Fans speed control

Q: Fans speed control

I have a problem: i just bought new motherboard and sometimes i have bsods. Well the fans works always at same speed and i thing it isnt ok. How can i make them chenge the speed in automatic, without FanSpeed software?

Preferred Solution: Fans speed control

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Fans speed control

Boohoo, no specs. In any case, a BIOS update may take care of it. I had a tornado going on my last board but a quick check and a BIOS update fixed it. There's usually fan control in the BIOS as well. Some motherboard manufacturers provide utilities that will allow fan and temp changes and/or alarm settings. System specs would go a long way in helping to provide specifics.

I have 3 fans in my PC, 1 of them is CPU cooler and another 2 are for blowing air in and out from my PC. The one what is blowing air in isn't on 100% and the one what must blow out air is just stopped so Where could i find place in BIOS to set their speed?

Or can you tell me some good program for that?

I just installed Win10 as part of the free upgrade package. I was using Win 7 Pro. Everything seems to be running real well with one exception, both of my fans are running at top speed. Nothing is hot. I checked the temperatures and everything is way in the green, not even close to being hot. Is this a known problem? If so is there a solution? I guess other than my fans wearing out sooner than normal it isn't a major problem but I'd like to fix it if possible.

Hello, I have put a new motherboard, power supply, and processor into a computer. The first time I turned it on with all peripherals plugged in, the fans stayed at max speed and it eventually shut down. I unplugged all peripherals except for the DVD drive, and then replaced the power supplie again and and the cpu has a temp of about 124 and the fans still stay at max speed, has not turned off yet.

Any Ideas??

I have 4 variable speed fans in my case; when I run 3D applications or run any other demanding programs, naturally, my computer will heat up. Therefore causing the fans to go ape-sh*t, constantly changing speeds. I phoned my system manufacturer and they said my motherboard was controlling the speed of the fans; I checked in my bios and couldn't find any options to do with then fan's RPMs. Then I updated my bios with a "bootable BIOS Flash diskette" that I downloaded from my system manufacturer. But there are still no options to do with my fans. After all of this I started looking for software to control my fans and so far have been unsuccessful. Does anyone know of anything that I could do, or any software that I could buy/download to solve this problem? It's really driving me crazy!

A:Variable speed fans

Are your fans plugged directly into your PSU or into your system board?

You're probably just not finding the settings. Look through your documentation...you're bound to find it somewhere.

After that...just call Micron PC and ask them.

So I assembled this PC:
Motherboard: Gigabyte GA-780T-D3L
Processor: Fx-6100
Ram: Hynx 2x2gb 1333mhz DDR3
Graphics cards: Gigabyte RX560 2gb gaming oc

I have 3 fans in my case and need to speed them up as my computer is overheating.
How do I check/change the speed of my fans?


A:How do I check/change the speed of my fans?

The simplest method would be to restart your PC and go into your BIOS. Most BIOS''s have a "PC Health" option, which will tell you temps and fan speeds.

Depending on the age of your motherboard, it might have options to control fan speeds.

Your specs don't say what CPU you have. You have a pretty good video card, so the obvious things to check are that the fans are big enough (at least 120mm), and you have good airflow

But, there are literally hundreds of threads here about cooling, overheating, and related topics. Rather than restate all of those, it would be worthwhile doing some searches here. You'll find plenty of good advice throughout the many threads.

hello i have the g500 i would like to know how to make the fans run constanly so it dont overheat plz help

A:how to make the g500 fans max speed

Hi TheRealTo , 
Welcome to the Community Forums. 
If you already have the latest BIOS from the support site , at the moment there are no options offered in the BIOS to change fan control as it is already pre-programmed thru its firmware to automatically launch on demand. 
If you currently encountering heating issue , best that you check further for any obtructions from the vents and call in tech support for checking further on the heatsink and fan assembly if needed repair specially if the pc is within warranty.
If you have the tools and skills for cleaning the internally , follow the hardware manual  guide .
Alternatively , external laptop cooler can also be an option.
Hope this helps.

I've encountered an usual problem... I recently had to pull 1 of the 2 video cards in my PC because it appears to have failed. Ok, not a big deal - not the first time I've had a video card die on my. (GTX 460's). Not sure if that's related to the problem or not, but thought it was worth mentioning as it's the only recent hardware change I've made.
A few days later - when I boot the PC, 2 of the case fans are running at maximum speed - the rear-facing case fan, and the fan mounted behind the motherboard - roughly behind the CPU. The CPU is liquid cooled. All temperatures are running under 50 degrees C, and this is from a cold start after hours of non-use, so no built up heat. The fans persist at maximum speed and never slow down.
I tried the trick I found online re: unplug and disperse any current to get the BIOS to reset, and it worked the first time but has not since.
Anyone have any ideas? The system still loads and appears to be running normally - no problems running any applications (including gaming) - but these fans are very loud at this speed.

A:PC fans running full speed

How are they connected controlled?

If they are attached to motherboard headers (not recommended), verify the BIOS configuration. Depending on the motherboard brand/model, there may be options for how they are controlled.

If that has no effect, the onboard controller could be faulty. You could simply install a fan controller, which is the recommended way to control fans anyway.

For a week now, my laptop's fans have been running full speed as if a process is running in the background. I've tried everything I know of to resolve it. Rebooted numerous times, cleaned registry, virus scan, full system scan, terminated processes using too much CPU memory, yet the problem persists. Its affecting page loading and searches when I'm on the internet, file retrievel, and gaming is jumpy.

Any suggestions?


A:Fans run continuously, High speed

The PC's fan speed should not affect the PC's performance. I suspect you have something keep the PC very busy causing the problem. The first thing to try is a System Restore and select a date before the problem started. Windows Help has more details on System Restore if you need it.

Switched on the pc this morning Fans running at full speed ... switched off and restarted two or three times with the same effect. Looking inside the pc the cpu was clean and virtually free of dust and connections were fine.I started the pc again and ran pc wizard to check temperatures (quad core ) all threse were fine, however noticed that one of the Hardware monitors was reading 90 c.(TMPIN1).

The pc is not very old

16 G memory

Thinking that the pc is still under warrenty thought I wouldn't start taking things to bits, so put the side on andthought I'd try it again ... I haven't really done anything , but it started fine and several reboots have been ok.

The only thing I did different was to disconnect the power lead and press the start button a couple of times ( discharge the caps).

Any ideas ?

REgards Roy

A:Fans running full speed

Yes, one idea. Sometimes a device in the system does not "enumerate" correctly during the BIOS boot. Put simply, the BIOS "names" each connected device and keeps a list (checksum). When you boot the connected devices are checked against the list. If one of the devices on the list does not respond correctly then the system has to try and resolve the discrepancy. The BIOS will not completely release the system to the OS until it has done so. If it gets stuck in a loop then it will search forever.

I believe what you accomplished was some sort of "soft" ClearCMOS. By cutting power and draining the caps you allowed the system to refresh. It found all it's parts and you are good to go.

This type of behavior does not need to indicate any failing parts. It can happen simply due to a minor power fluctuation or data logjam. One time does not make a pattern. Keep your eye on it and if it happens more often then you may need to look into it further.

Good day,

Sorry for the vague title, i'll be as precise as I can describing my problems.

First of all, whenever I start my computer, more often than not, the fans go full speed, I can use my computer normally until it heavily slows down, the sound when playing music is messed up, and there it happens, the shut down. This usually happens after 10 to 15 minutes after startup.

But here's the thing. When I start it up again after that, it works fine, fans are quiet, everything runs as smoothly as it can. Not a single issue. So, that's the first problem.

Now, the other issue I encounter, is that one of my fans, speeds up, and down, and up, and down, whenever I launch Steam. Not a game, just Steam. And it'll do that, until I close it. It happened before for one specific game, but I thought it was, well, an issue with that game only. Now it does it whenever I launch Steam.

Any ideas about the why and how to fix it ? Thanks for time you took reading.

I have a Dell Optiplex GX 280 medium tower with XP Pro. It was working great and I sent it to my son via UPS. When it arrived. It wouldn't boot at all. I now have it back here.

When you push the power button, I get a yellow light and the fans turn on but run at a very high speed. On the inside I get a constant yellow light which indicates a hardware failure.

I have disconnected and reconnected everything several times, changed the memory, cleaned the processor and added Arctic Silver 5 to the CPU and Northbridge.

The CD-ROM tray works but won't read anything. It won't start in safe mode and won't bring up "set-up" or "boot sequence". The screen never shows anything.

I found a couple of problems similar to this on Google but have tried everything that anyone suggested.

My question: Is there anyway to isolate the problem. It's an older computer and not worth the expense of just replacing parts at random.

Any suggestions appreciated.

I'm picking up a few (3) 2-pin 12v fans to put into a isolation box I am making for my present computer. I want all the fans to run simultaneously but want to be control them via an external pot. The problem lies in how to control them all at once.

I haven't been able to find a single variable resistor that could control all three together which means I might have to wire them in parallel/series. I know the impedence would start changing drastically, but is it feasible if I use an external 12v power supply?

A:Rigging up simple variable speed fans

Use this config. You will want to have the pot plug in from positive to negative on the ends that the resistance does not change. The connector that the resistance changes should be connected to your fans positive connectors. ground connections should be connected directly to ground. This is a parallel set up. If you set this up in series, each fan after the first will have less power and will spin slower.

Not sure how best to describe this, also confirmed by others who have updated to BIOS 1.1.3
since installing the BIOS update the fans will rev to full at various times, rebooting is one time, they are forced to 100% with no ramp up, this causes a high pitched noise as the fans cannot cope with being revved up so fast.
When the fans kick in they will not kick in at 2500rpm (minimum), they will ramp up about 1000rpm faster then settle down.
This has never happened in the time I have owned a 9550 and 9560 until this new BIOS update.
I have reset the BIOS to defaults a few times, reflashed the update and it still does it.

Changing Dell power command doesn't help either.

Device Manager, Mice, rightclick on HID-compliant, power Management,
uncheck "allow this device to wake the computer"

(I'm not 100% sure on this but this worked a few months ago. Fans came back on recently, and I see the box became checked again - probably due to a Windows 10 update, so I unchecked it again. So far so good)

I have an Emachines T6414 with a new videocard and sound card, neither of which require a seperate power connector than their slot on the mobo. THey were both in the machine for a few months when I decided to update my BIOS. I was updating my bios, and everything appeared to have worked. At the end it said: "success...press f1 to reboot" so I did. Then the problem started.

When I rebooted the PC the computer did not post, it only had all the fans (CPU, Main and Videocard) going full blast and the hard drive made a little noise, but nothing booted. I reseated the CPU, same thing. I called Emachines tech support and decided that the bios process actually didn't work. So, I bought a replacement bios from an online vendor, Biosman. I gave them the BIOS that the tech support had emailed me. I switched out the bios for the new one, and the same process happened still-no post, full fans and the hard drive warming up. At that point I bought a new PC and got the Geek Squad to transfer the data over.

So now I have come here for a last gasp attempt to revive the POS. I just read that the power supply could be the culprit. How should I determine what part has become faulty?

Thanks in advance. :dead:

Hi all,

So I've had this computer with few issues since I built it but recently whenever i start it in normal mode it runs fine for about 12 mins then the fans (GPU I think) start whirring at max speed and it stops sending anything to the monitor. It works fine all day in safe mode. I've tried: reinstalling graphics drives, reinstalling windows (+ reformat), dusting it, resetting the CPU with new goop, resetting the GPU after dusting, prayer to gods old and new etc... I haven't messed with bios at all. Can anyone help me resolve this? Was there a bad driver released or is this definitely a hardware issue? Thanks!

For reference I'm running:
ASUS p867 le mobo
AMD radeon HD 6950 GPU
Intel i5 2500K CPU
Windows 7
some ram and shiz etc

P.S. sorry if this is in the wrong forum.

Starting about two days ago both my case fan and CPU fan have been stuck running at full speed  constantly.

I have already attempted updating drivers and updating windows but nothing has resulted in a fix, i'm not sure what else to do

I've been using Windows Vista for many years, and I've finally done some more depth research into CPUs and upgraded. With the upgrade (as the new core is 64 bit whereas the old one wasn't) I decided to upgrade my OS to Windows 7 Professional.
Mostly it's great, but I've noticed that after the computer is woken from being asleep that one of the fans is running at it's maximum speed until the computer is restarted. This is irritating for two reasons as I don't want to wear my fans out and because it is very noisy.

I do use speedfan, but generally have it set to run off the automatic fan speed. Usually the fan runs at around 1560 RPM depending on what I'm doing, but when this error is happening Speedfan is registering it at over 4000 RPM and this continues until a restart.

For now, I have disabled the sleep function to avoid this, but it would be great to know why this was happening and how I could avoid it.

Thank you!

Hi @FizzyLicious, Welcome to the HP Support Forums. From your post, I gather that your Compaq no longer boots up but the fans are starting and some of the lights used to blink but don't seem to be anymore on startup. Please follow the troubleshooting steps in the HP and Compaq Desktop PCs - Resolving Startup Problems (Windows XP, Me, and 98) document. It will walk you through the troubleshooting. I suspect that you are going to end up having to follow the steps in the HP Desktop PCs - Computer Does Not Start and Emits an LED or Beep Code document. If this post helps you to resolve the issue, please pay it forward by clicking "Accept as Solution", to the right of the Thumbs up icon.

when I boot my PC, the monitor stays blank, the gpu cooler runs at full speed and I get the 1 long 3 short beep code from bios indicating malfunctioning RAM. Nonetheless, the system boots, but without a video signal. After shutting it down and restarting, the system fires up just fine and runs smooth as ever. That happens only if I leave the PC turned off for some while.

Before that, I had sudden powerlosses while playing games. Therefore I replaced the PSU. After that the troubles described above began.

The operating system is Windows 7 64 bit

My hardware:

Mobo: ASUS M3A79-T Deluxe
RAM: 4Gb Corsair XMS
CPU: Phenom II X6 1090t
Power: Enermax Revolution87+ 550W
GPU: XFX 6870

I have read, that several others had similar issues, but none could come up with a solution. The best solution I found, was replacing my GPU, which is a PCI-E 2.1 version, by a GPU that uses PCI-E 2.0. But that's what I'd like to do least. Especially since there should be no complications between PCI-E 2.1 and 2.0.

I am desperate for suggestions.

I have a new SATELLITE S50-B 15, i7-5500U, 8GB Ram, SSD etc. and iv been having a few issues with it.

for reasons unknown the CPU fan will start running at high speed even though the CPU temp has not reaching 35%.
it has also frozen about 10 times since I got it (April this year).

The only way to get it working again would me to hold the power button until off and start it back up.
Once started back up there is no mention of any problem in the event logs other than the forceful shutdown.

I just wanted to know if anyone else has experienced any issues?



A:Satellite S50-B 15P - Fans running at high speed and system crash's

The only way to get it working again would me to hold the power button until off and start it back up.

Forcing shut down resets the fan activity and the performance?
Hmm? this sounds like there must be some kind of system issue? probably the some background processes locks the CPU and therefore the fan activity increases.

You could start the task manager and in the tab called ?Processes? you will find all background applications which would use the CPU.
Click on the CPU column to show all processes loading the CPU.

At the other hand you could also try to modify the ?cooling method? option which is available in Windows advanced power options.
Go to control panel → power options.
Here click on the power plan which is currently in use.
Then click on Advanced power options and navigate to Cooling method.
Here you can change this from active to passive.

Additionally you can decrease the max CPU state to 90%-05%

I'm having a big issue with my computer and seeking all the help i could get. Many thanks in advance.
This issue started upon the first day of building my new computer. I did not care about it due to the fact that it did not occur that often. Maybe 1 time a month, not more. The issue did also only appear when running Alpha games, so did not reflect that much about it as it could be memory leaks etc in these Alpha games.
- Whats the issue? Computer freezes and the display turns black with the fans running on highest speed (All of the fans). Any music/game -sound in the background freezes and sounds like "Bzzzzzzzzzzzzzzzzzzzzzzzz". This remains until i force a shut down. No Minidumps are visible as this is not a bluescreen.
- Something iv'e noticed and could be worth mention. The black screen got worse and more intense after i replaced my 2 screens with a brand new Samsung 34 inch curved display. 
- I tried only a few things thats within my reach. Replacing the mems, resetting the bios etc. Nothing more.
- When connecting the computer to a low res tv (1920x1080) its working as intended, no black screen.

Hey there, i changed my computer case about 3 days ago, all went well, only a few minor issues that were fixed, PC was running fine all day today, went out then when i came back turned it on and all is fine, after about an hour i decided to start a game (League of legends) all was fine until the loading screen came up, suddenly i heard my computer fan getting faster and faster and louder, before i knew it the fan is running extremely fast and the PC just shutdown instantly.

Now whenever i try to boot the PC the motherboard beeps and windows will load, but the fans are going at maximum speed, and again the PC will eventually just turn off after about 30 seconds (i believe its my GPU fan) i have tried replugging the wires and my graphics card but this has not worked.

Please help

A:[URGENT ] [HELP NEEDED] Computer turning off FANS full speed

It sounds like the system is overheating and shutting down.

I would check and make sure the CPU heat sink and fan are still properly attached and have not been knocked loose during the chassis change.

I got a R850 and complete random the laptop lockups. When it locks up fans begin to spin full speed and windows is locked up. I need to poweroff the laptop and start again.

This can happen three times on a evening, but it can also occur only ones a week.

Its complete random.

A:Tecra R850 - sometimes OS stuclocks-up, fans spin on full speed

On this virtual way it is not easy to say what happen exactly.
Every new notebook is delivered with clean preinstalled OS and something like this should not happen. Later when you start to install updates or own applications it can happen that some background application ?blocks? the system.

In my opinion either you must check preinstalled stuff, processes that run in the background to see which one can be responsible for this, or you must install recovery image again and check how it works with ?factory settings?.

The laptop was put to sleep and after about 30 minutes when i tried to switch it on, it showed no response. So i put the power cord in. As soon as i kept the power cord, the fans ran full speed. This behavior repeated whenever i pressed the power or recovery key. Eventually the battery drained out and now its totally unresponsive except for the battery light glowing brown (red plus white) Help !

Hi guys, hope you can help me please. I'm not too computer savvy so sorry if I'm missing something important or I say something dumb. I'm really frustrated and I'm trying my best to learn and solve this problem.
So I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communication...

Hi, welcome to the forums,
Go to Device manager(right click bottom left corner), uninstall the "VAIO care" driver, get the new driver from Sony support:Sony eSupport - Computers - Support
Install and see whether it helps, check your system for virus infections with Malwarebytes as well.

i got da program speedfan 4.32 and i cant control my fan speeds it doesnt even show my fans rpm..

A:why cant i control fan speed

It depends on what motherboard you have, that will allow Speedfan to work properly. The fans that can be controlled must have 3-wires. You can always install a fan controller, if you really need to control fan speed
