CPU load based fan control

[Samwell]

Hi

 

Does anyone know of any software that can control a fan based on CPU load?

CPU load is too erratic for it to be a reliable fan control.  Temperature goes up and down much slower than load so that's what people use.  Otherwise your fan will spike up and down all the time with CPU load.

SpeedFan will do the job!

 

EDIT:

 

SpeedFan will let you adjust the temperatures at which the fan speeds up

Well I was thinking of using it more for 'if CPU is above x frequency for y amount of time, speed up'. The temperature sensors for an older motherboard and CPU I have are borked so I can't use temperature based control

Do you know how to make it work with CPU load? I had a look into it and I can't work out how

You can configure the fan curve for CPU fan according to temperature inside the BIOS, then, the temperature always rely's on your CPU's workoad. You can get a splitter if you want to power more fans

Temperature pretty muxh depends on how loaded the CPU is. And if it's not actually heating up, why would you want to generate more noise?

It's not very useful to tie fan speed to frequency- the reason being that frequency jumps around A LOT- sometimes some cores are parked while others are at high freq. And additionally, even if you are at a low frequency, you could be at a high temperature due to something else in your system or the ambient temp.

 

Remember that fan speed is directly for lowering cpu temp. So, theres little point in raising speed unless it really needs cooling- but you can adjust the cooling curve to high speed fan kicks in more quickly.

There is no way to tell what temperature the CPU is at. The way the computer is used right now is the CPU idles most of the time but it sometimes needs to ramp up to 100% for half an hour. In the BIOS it says the CPU is always at 73 degrees (Celsius) and the system temp seems to be in a world of it's own.

Use cpu-z or msi afterburner to check the temperatures

Edit: CPU at 73°?! Run a Aida64 stress test and check at what temp does your CPU get at and chack if it's throttling

Tried those along with a couple of other pieces of software, none worked. Gigabytes own software reports -21 for the CPU and -32 for the system. I'd have thought that if the BIOS can't read the temps, nothing else has a chance?

I know there is something wrong with this motherboard and CPU but for now it needs to run. It reports 73 all the time. As soon as I boot up, after a stressful load, it never changes. It's frozen at that temperature and it won't change, which is why I can't use temperature based readings. Because there is no reliable temperature to go off. When encoding video it goes to 100% for about 10 minutes then switches off from overheating. I just need something to tell the CPU to ramp up when its at full load because the rest of the time, 35% fan speed is enough.

I dont think there is anything that controls fans based on CPU load sorry

How old it is? can't you RMA it?

Was bought 2nd hand ages ago so nope. Its used as a home server which is why there is normally very little to no load on it at all. Only when encoding ripped DVD's to mp4 does it overheat.

Does the heatsink feel hot? Otherwise you could connect the cpu fan to the PSU directly, will run at full speed always, but will probably not have the overheating issues

It does get very warm when encoding (otherwise it feels cool to the touch). Well I have fan controlling software which allows me to set a speed and let it go. But if there's a way to not have to do that then I'd rather not. Because it's rare that I need to rip a DVD and having the fan on full isn't an option due to where the server has to live. I was thinking if there is no software that can do it, I'll have to heavily underclock and undervolt the CPU until I can find a way to quietly cool it (get a very large heatsink and some quiet but powerful fans)
