T470 i7 constantly CPU thermal throttling?

Q: T470 i7 constantly CPU thermal throttling?

Hi all, First of all, I love my T470! It is by far the best laptop in this form factor on market. To be brief, I used HWiNFO 5.52 today just wondering what info can I get from many sensors. However immediately when I open the sensor status window, I see it used red font to shout out that my CPU core #0 is thermal throttling. I get interested and kept watching on, and I find that ever a few moments (probably a few tens of seconds to no more than 2 minutes) there will be a short moment that either core #0 or #1 is thermal throttled, or some times both. So I tried to look a bit into the issue. I searched Internet, but could not find a explanation yet. I tried to restart and immediately after boot it is doing this. I left it unwatched for a while, then it is still doing this. I restored OS, removed all attached devices, and load defaults in BIOS, it is still doing this. My question is, should I be worried? During the whole time I am very sure there's not a hot spot on surface of the laptop. And HWiNFO reported CPU temp range never exceeds 72 degrees Celsius on either core, with a average around 50. Although I would think the temp is not low, but I really don't think it qualifies for throttling all the time. Is this normal for new generation i7? Or is there something wrong with heat sink in my laptop? I attached a screen shot of HWiNFO just in case. Thank you all for reading!

I have a T470 with a I5-7200u and the cooling is not performing optimally. When I first got the laptop I could run it under full load for hours and the cpu temp wouldn't even budge from 50 degrees Celsius. When idling the fan would almost always be off. Recently however things have gone not so optimal. The fan usually runs at high speeds when the computer is idling. The cpu temperatures sometimes get all the way up to 60 degrees celcius. Once it got up to 70. When I run some heavy work like 3D rendering I can't even get to 3 GHz on turbo boost. Then sometimes it runs cool while idling. Any ideas to the cause? Thanks

For some reason, my laptop will throttle my i5 down to 5% CPU speed (0.38ghz) when it's on battery - Slows the laptop to a crawl. I've set the min. speed to 50% but I have a feeling something is wrong. 2.

Hi, My CPU has been throttling down to 400 MHz when on battery. This does not necessarily happen on low battery - it sometimes happens when I have over 50% battery life left (albeit the removable battery is low), and sometimes when i have less than 25% battery life left. My temperatures appear to be good (according to Core Temp), usually around 40-50C. Has anyone encountered this problem before? All of my drivers are up to date according to Lenovo companion, and I have placed power settings in windows to High Performance, and changed the Intel Speedstep settings in the BIOS to max performance as well.

Hi, I have a y50 with an Intel i7-4710HQ and a GTX 860M.The biggest Problem I have is that after a short while it automatically throttles the CPU down to 800Mhz and while I do understand the need to limit CPU-Speeds at high temps, all cores are running at about 50 degrees Celsius.While I do understand that conservative Threshholds are probably in the companies best interest, overdoing it and in consequence making the Notebook almost unusable probably isn't.I was wondering if there is any way to loosen the Threshholds or maybe doesn't let it throttle down quite as much so i can actually have a reliable Notebook again.

Hi all,I recently purchased a P51 laptop with a I7-7820HQ CPU and Nvidia M2200 GPU.What I noticed, almost immediately, is that the CPU fans frequently reach high RPMs (~4500) even when loaded only for a few seconds during application launch.Testing with Intel Extreme Tuning Utility uncovered almost immediate thermal throttling, only a few seconds after a CPU stress test is launched. Expected core frequency of 3.5 GHz is reached only briefly and after this it is throttled to 2.7-3.0 GHz within 5 minutes of the test.Since the system board was replaced recently, I guess there is a possibility of improperly installed cooling system, however, what causes additional concerns is a big temperature difference between the cores which is more than 20 degrees Celsius under 100 % load.Except this, it seems that the air coming out of the laptop during the stress test is only slightly warm and significantly cooler than what I am used to on other laptops.On the other side, Nvidia GPU seems to behave quite well under stress test (Furmark).Except this, I also tried to run Intel Processor Diagnostic Tool but the test failed before reaching GPU stress test because of too high temperature with the following result:Current Junction Temperature is 99CCurrent Degrees Below Max 1CMaximum Junction Temp Allowed 100CTest Result - FAILPlease check your Processor Thermal SolutionTemperature Monitor Stopped by User Can you please advise how to solve this issue and share your results with similar lapto...

So I built my PC just over a year ago and have had absolutely no issues with it, until about a week ago. I noticed that my PC was running slower than usual, I was getting FPS loss while gaming, and everything else lagged too - opening/closing programs, switching tabs, etc. After downloading a few things to check what was going on, it appears that my CPU is thermal throttling. This is strange, as my PC states that the temperature is sitting at about 27-30 degrees Celsius. As soon as it throttles, the multiplier drops to 8x, causing my core speed to get stuck at 0.80GB, which is why it starts to lag (rather than 36X multiplier at 3.6GB speed). Sometimes my CPU throttles the entire time, from the moment I turn it on. Other times, I can see it fluctuating between 8x and 36x every few minutes. When I run a CPU stress test, I noticed that the temperature doesn't change (stays at 27), which is making me think maybe the heat senses aren't working properly. If the CPU is actually very hot, I don't understand why it's hot now when this was never an issue.
The CPU fan is still working. I've dusted out my entire PC. Yes, all power settings are on high performance. The slow-mode switch on my motherboard is turned off. I've reset the BIOS. I've turned off EIST (Enhanced Intel SpeedStep Technology). I haven't made any changes to my PC for this to be happening. What could be the problem?

I purchased my Z710 Laptop 2-3 years ago. Currently I seem to suffer from thermal throttling on both the CPU(i7-4700mq)(85C) and GPU(gt-745m)(75C). I tried cleaning dust from the fan and heatsink but that did not seem to solve the issue. I tried to underclock CPU down to 2.4GHz but still reaches 85C and GPU still throttles as well. So I am thinking of two options:1) Buy a laptop cooling pad and put it under the exposed underside of the laptop and hope that it can cool it down.2)Replace the thermal paste of the CPU and GPU (boy oh boy how sketchy this one is, but exciting at the same time!) and hope for the best? I am looking for your advice on which of these I should choose or if there is anything I am missing? Thank you in advance!

Hi everyone, I am new ownere of P71  E3-1535M   CPU and NVIDIA Quadro P5000  GPU.I am not too familiar with thermal and current level throttling but I am experiencing both on my 2 days old mashine.  Would someone give me quick explanation of what is normal and what will eventually harm the hardware over time? I bought this laptop to keep up with some more intensive tasks that come with interior designs and 3D rendering that comes with it.  When I start rendering I see Thermal Throttling nonstop and current limit throttling on and off eery other second. CPU temperatures running between 90-94C  with Core frequency around 3.57 GHz.  Greaphics temperatue around 70C. See attached screenshot from Intel XTU.   Is this normal or do I need to call Lenovo to get it corrected?  If there would be no Thermal throttling and Current limit Throttling would I see faster core frequency?  Sorry if these questions have ovious answers.. It's a lot of money for me and I want to make sure  I am getting best use of it now and in the future.        Thank you for your input.   Charles

So I finally received my heavily delayed P71 and so far I'm pretty happy with it save an issue with CPU throttling.  I noticed when doing extremely CPU heavy SQL or GIS analytic workloads that the frequency was constantly dropping from 3.9Ghz (4 core turbo) down as low as 2.4Ghz.  I downloaded Intel XTU and pretty quickly found the problem...it's running into BOTH current and thermal throttling!   In the graph below the yellow and red spikes are thermal and current limit throttling, respectively. I can reproduce this with either real world workloads in SQL or various GIS applications and using synthetic benchmarks as well (XTU, AIDA64). I might expect this from a gaming PC but certainly not from a mobile workstation costing almost $5,000. Specs:Xeon 1535m v6Nvidia P400032GB DDR42 x 512GB NVME RAID 02 x 1TB SATA software RAID 0 All of these tests were done on a raised, vented monitor stand for the best airflow. I'm sure an undervolt and repaste would take care of the majority of the problems, but I simply refuse to have to go that route on a PC in this class. Thoughts?

Hello all I've just got myself a M93p tiny desktop and it's a great machine apart from one problem... In gaming (light gaming, OpenGL DOOM 2 and Unreal Tournament at 1080p) the machine is suffering from thermal throttling. I've applied Thermal Grizzly thermal paste (said to be the best thermal paste you can buy) to the CPU but still it throttles itself causing a massive drop in frame rates. I also notice it drops performance a lot in Handbrake video encoding where the encode rate goes from 60fps to around 27fps. My CPU is the quad core i5 I5-4570T. I know this machine has a pretty small cooler but even with the best thermal performance setting selected in the BIOS it still does it and the fan doesn't seem to speed up to help the thermals. It just stays quiet which is great but I expected it to speed up under load and cool the machine instead of thermal throttling first. I've also tried to disable the ICE thermal alert setting in the BIOS. Do any of the newer BIOS releases address this issue or help in anyway as I'm 99% sure I'm using an old BIOS revision. Are there any solutions to this issue as it makes the quad core CPU rather pointless as it just throttles itself and performs half as well as it should whenever you do something taxing.  Any advice or help greatly appreciated.

A:Pavilion dv6 overheating (7690m XT thermal throttling)

Hey guys.. So after finding out that some people on this forum are rude, and tell you to download drivers that were released in 2011, I decided that I would experiment a bit. Updating my drivers did indeed do the trick (GPU temperatures dropped from 103 degrees to 87 degrees in the same game after the same period of time) I did not use HP's official drivers because I already had their latest version, and it made my GPU thermal throttle like mad. PS: If you have the 7690m xt GPU, it is indeed the 6770m just with 2GB memory instead of 1GB BEFORE DOING ANY OF THE STEPS BELOW, I WOULD RECOMMEND MAKING A SYSTEM RESTORE POINT  I downloaded the drivers that are found on AMD's official website ( http://support.amd.com/en-us/download )Because I have 7690m xt (AKA: 6770m), I downloaded the drivers under following heading: AMD Radeon? HD 6000M and HD 5000M? SeriesOnce the driver download is complete, go into device manager and open the "Display Adapters" drop-down menu. Then delete the AMD GPU's drivers. Don't worry if your resolution looks a bit weird now. Then download Driver Fusion ( https://treexy.com/products/driver-fusion ) and delete the remains of the AMD drivers.Restart your notebook.Switch of Wi-Fi or any other mechanism of connecting to the internet.Install the AMD drivers downloaded earlier.Once installation is complete, restart your notebook.Everything should be good now. You can also switch Wi-Fi back on if needed

Until recently the laptop worked fine, but now it experiences something that resembles thermal throttling.
Initially, everything is OK, but after 10-15 min of heavy use (and by heavy use I mean a 1080p youtube video), it starts to really chunk the responses. You would think is because is overheating, but the temps never gets really high.

[check attachment for higher resolution]
As you can see, the highest temp was presumably 77C, and the current one is 50C, while the On-Demand Clock Modulation is 50%, but it feels way worse. Once the ODCM kicks in it's very slow.
I'll give it a good clean inside and a new thermal compound this weekend, but I doubt that's the issue, it looks clean already.
Any thoughts on why is ODCM kicking in ?

Power Limit 1 goes from 45w to 20w then back to 45 for about 10 minutes, then goes down to 15w and stays there for an undefined amount of time (even if temps are low at about 75 degrees)

Hello everyone, I have a lenovo z51-70 with i5-5200U and 4gb r9 m375. It has been performing excellently for the past 1.5 years or so, but suddenly one issue came up with gaming. When i game, its fine for around a minute and then the game starts stuttering, checked the cpu speed and found it to be 0.48Ghz, which dropped from near 2.6Ghz. Checked out the intel extreme tuning utility when this happens and found that it was THERMAL THROTTLING by the CPU, this doesn't happen even when benchamrking.So, I want to know why this thing has suddenly started out in my laptop and is there any way to cure it. Other info: Haven't changed anything with that tuning utility, drivers and all are updated, still in warranty, adapter connected to the socket, gaming in high performance, cooling policy set to active, max cpu usage set to 100%, virtualisation enabled(default) The picture: Started the Witcher 3 to show the throttling, the peaks are when the game was running and then suddenly after 30s, poof to 0.48Ghz. Memory consumption is normal, it will reduce after i have shut down the game.

Hi everyone, I just got a Thinkpad x270 and I'm having an issue where the processor gets throttled to 60c / 2GHz when the lid is closed on battery power.  I posted about it in detail on the Linux Mint forums here.  I originally thought this was a Linux kernel / driver issue, but it turns out this happens on Windows too, no matter whether I set every setting in the BIOS and OS power management to max performance, power save, balanced, etc.  I can get around this by closing the lid on A/C power and then unplugging, or just running the  laptop on A/C while the lid is closed.  If there is some kind of inherent danger in running the processor over 60c with the lid closed, I would expect it to thermal throttle at that temperature regardless of whether or not it was plugged in when the lid was closed.  I can also boot up the laptop with the lid closed and bypass the throttling limitation. It seems like either:- the temperature should always be throttled to 60c when the lid is closed for some reason, and it's not being enforced in all scenarios even though it should be, or...- it's a bug and the CPU shouldn't be throttled at such a low temperature at all. Either way, it seems like there is a firmware issue that needs to be fixed.  Can anyone from Lenovo shed some light on this issue?  Is it by accident or by design?

Hi,
I got a new Aurora R7 yesterday, with Intel core i7-8700 CPU. Right off the bat, when I was installing browser, and doing other small stuff, I could see that the fans would spin at high RPM and create a lot of noise. 
I opened Command center and saw that at small loads 15-25% of CPU, the package temperature was high, from 68C going to 84C and fans would spin high and it would again come down to 60s.
I decided to do stress test using Dell Support assist and temperatures reached 98-99C within 3 minutes and fans were blowing so hard it felt like an airplane was about to takeoff.
I decided to dig further and downloaded Intel Extreme Tuning utility. When I run stress test, I can see that MAX Core Frequency drops to 4.28 GHZ and temperatures rise to more than 90C. It does not reach the processor max speed of 4.60 GHZ at all during stress test.
I feel there is an issue in how the CPU and Heat sink are connected and something is wrong.
What do you guys think?

After i completely dignosed the issue it seems to me that there are problems in BIOS, Drivers and thermal management as when I start playing a game (GTA 5, Battlefiels 1) i runs smooth for 5 minutes but after that i starts lagging and freezing. I have also run some benchmarks but results are similarly as there is the issue of cpu thermal throttling. And audio distortion is due to unstable and poor compatibility drives. In dell forms i read people saying that all this is caused due power management issues which i have also noticed as when CPU is idle is consumes around 20 watt at 50°C but when put under load it once reaches 50 watt of peak usage at 100°C but with in few seconds it thermal throttles and used only 15 watt at 80°C which is even less than idle speed which causes many problems and freezing also all with in few minutes of gaming or proper use. Many uses are facing same problems as i have read on reddit and dell community form but not all the systems are affected as the review units that some YouTube channels and Websites like Laptop Mag reviewed did not exibit such problems or otherwise the reviews are fake. I don't know why dell is not solving the issues and sending me the same problematic Laptop again for the third time.!!

Hey, I have the following problem: For some time now, my U41-70 throttles down to 0.48 Ghz with the fan constantly running. This behaviour is likely to something called thermal throttling or BD PRODHOT, where other hardware tells the CPU to throttle down in order to not overheat. The throttling can be circumvented using Throttlestop (or MSR on Ubuntu), but having the fan constantly running is quite unbearable. I already tried a number of things, including updating the BIOS. Unfortunately, in the BIOS there does not seem to be an option to turn of thermal throttling altogether. I also cleaned the fan, and tried to change the fan speed manually. None of these measures had any effect. My interpretation of this is that some heat sensor is broken, because the the sensors I can access rarely show a temperature above 40C. I do not have any warranty any more, so I can not just send the laptop in. If I could make out where the faulty sensor is, I could maybe exchange that part of hardware. Does anybody have an idea what part I should replace, or how else I could solve this?I run my U41-70 on Windows and Ubuntu, with the problem occuring on both. I have a 256GB SSD, an Intel Core i5 processor and 8GB RAM.

Hi, I have recently received a brand new T470 (20HE model, i7 CPU) and ordered it together with a Lenovo Thinkpad Bluetooth Laser Mouse.OS is Windows 10 64-bit. This problem below has happened all the time, with brand new laptop and mouse hardware. I.e. it has never worked during the time I have used the machine. I have the strangest problem: The mouse disappears & stops functioning completely sporadically and sometimes "all the time". It may work for 30 seconds, stop working -> recycle power button -> works for 1 minute and stops -> recycle power button -> works for 5 minutes.. etc etc. My actions to resolve the situation so far: - Download & install latest Bluetooth drivers from Lenovo site- Download & install latest Bluetooth and WiFi drivers from Intel site (after I discovered there was something newer there for 20HE)- Uninstall & Install Lenovo mouse suite- Remove and Pair the mouse several times- Adjusted WiFi band preference to 5GHz (after reading that it helped some, due to possible interference with WiFi)- Disabled WiFi device- Changed batteries to the mouse (problem started with a brand new machine + brand new mouse with new batteries)- Tested the mouse on another laptop (HP) where it worked without a single interruption- Adjusted "Allow windows to shut down this device -> uncheck" Power management settings for all possible Bluetooth related devices, Mouse related devices, wireless chipset devices => Nothing...

Have scouted around in the forums & don't see this topic, so here goes. Would appreciate some guidance on the optimal placement for thermal pads & thermal paste on an AMD FirePro M6100 graphics card in a Precision m6600. I am upgrading the stock FirePro M8900 to the M6100. The cards are similiar, but not identical. I know I need to put thermal paste on the GPU itself, so I've secured some IC Diamond 7 Carat to do just that. However, the VRAM's & other raised surfaces on the card most likely need thermal pads or paste & the vendor just put a big light blue/green thermal pad in w/ the card & doesn't have any guides on where it is to be put, exactly. I have plenty of pad material to use from the M8900 & heatsink currently in the notebook, as well, & have re-purposed many of them, but temp still spikes to 90 degrees & climbing when it's pushed w/ high-end graphics in various applications, so I'm looking to stop that. Greatly appreciate any pointers you can provide. Have contacted AMD re: this & they said I need to ping Dell. Have reached out on several forums as well & still no go. Thanks again!

A:Precision m6600, AMD ATI FirePro M6100 FireGL graphics card installation, thermal pads and thermal paste

Hi there... I know the post is old but would like to share my experience on the topic. I have the M6600 with 2820QM processor and AMD M6100. When adding thermal pads over the GPU there is a potential for the GPU card to bend so I did not risk it - I simply added thermal paste. The GPU sits perfectly flush on the heatsink body, the supporting hardware modules around the card also sits flush on the segments within heatsink body. My unit is happy at 47 celsius when idling, and will not go over 85 celsius when pushed to the limit. I suggest that you keep it simple and and just strip the pads out.

This is all about the chronic heat problem on HP consumer-grade laptops. I need an opinion on thermal paste vs. thermal pad on a dv5-1002nr, before I start tearing the whole thing down. Prior to that, I had no problems - I was running VM's, multiple browsers with several tabs as well as streaming music/video, with temps ranging from 40-85*C on Power Saving Mode (maxes out to 54-72 when used in conjuntion w/a custom laptop cooler; and set to High Performance Mode). I haven't really opened the unit for cleaning since purchasing it back on 2008, save for a whiff of CO2 spray at them vents for those dust bunnies. But this time, it seems that the average temperature of my unit has risen to a steady 60-82*C, even on PS mode. Having not visually checked the CPU as well as the cooling elements - esp. thermal pad (?), maybe it's time to tear the laptop apart for inspection. My questions:

- Does the AMD core use a thermal pad, or a paste?
- If it uses a thermal pad, can I use thermal paste instead?
- Any (good or bad) consequences in using a paste or pad, for that matter?

*AFAIK thermal pads shrink from heat over time; same thing with thermal pastes that dry over time. All translate to head, as I have seen on desktops. But for laptops.....not seen yet
 

A:Needs opinion on thermal paste vs. thermal pad before I tear my dv5-1002nr!

I think you will see in this forum that BOTH are recommended ......

I prefer paste - but then I only make a couple of machines .....

you may find that the cleanup does the Job without having to remove the heatsink - and its only a couple of years old at most.

Is there any real difference between the two? The pads are so much easier, I have trouble getting a unified layer of paste to apply properly. I know the differences in manufactures. The reason I ask is I have an AMD64 3700+ with a Zalman CNPS7000B cooler and my temps are +50 under load. This seems too high for me, especially since I am not even overclocking her yet. Thanks for all your help.
 

A:Thermal pads vs thermal paste

paste is waaay better. Artic silver 5 over a pad will probably drops temps 7 degrees.

First of all hi everyone, great to join such a good forum.

I was looking a bit of advice on what would be the best to use, thermal paste or thermal pads. I'm currently using a thermal pad that was already on my arctic freezer pro and it seems to be doing a good job, sitting around 36c.
Would it be better to use the paste or just use another pad as i have never had to apply the paste before and am a bit dubious about doing it if i don't have to. Also if applying the paste would you say it's better to apply it to the heatsink or to the cpu itself.
Many thanks in advance.

With regards to your question, apply thermal paste to the cpu directly, the paste should come with instructions. The paste i have says that you should rub a small amount of it into the base of the heatsink but do whatever the specific product tells you to do.

If you don't think that you need to replace your paste then don't worry about it, 36C is a pretty good temp.

Hi, im just in the process of building my brothers computer. I bought some artci silver thermal paste and planned on using it, but reading the AMD instructon booklet that came with the AM2 3700+ X2, it says that the heatsink provided already has thermal paste applied to it, and it does. i was wondering if that is enough, and that i should just slap it on the processor with that stuff on, or should i add teh artic silever (do you put it on the processor surface) as well and have them both? I heard that too much is just as bad as too little, so what should i do?
 

A:Applying thermal paste to heatsink 'pre-loaded' with Thermal Paste?

All I've ever run in my computers are AMD chips. The pre applied thermal paste is enough. You don't need to add any more. I overclock my chips and I haven't run into any problems as of yet with overheating.

Don't all Heatsink's come with a Thermal Pad(s)? If so why would anyone who keep their CPU's in for large amounts of time, or do not alter them want to bother with Thermal Gel? I say this because apparantly Thermal Gel is only for tests and quick use, according to AMD. They also specificly say do not apply Thermal Gel in conjuction with a Thermal Pad, is that just AMD?
 

A:Heatsink - Thermal Pad/Thermal Gel

Some heatsinks don't come with a thermal pad, ones that come with the processor do, but many aftermarket ones don't. Also, thermal pads aren't as good as thermal paste for dissipating heat, which is why many people who push their CPU's past their limits (overclocking) use thermal paste, to help keep the processor as cool as possible. Combining a thermal pad with thermal paste makes the distance between the CPU and the heatsink too big, so the processor stays hotter.

I don't know why they say thermal gel is only for quick use, unless thermal gel is something other than thermal paste....Arctic Silver takes at least 24 hours or so to get to its' optimal state, so you wouldn't want to use that for a quick test.
