GPU fan speed ramps up and down during "idle" usage

[DONK89]

Hi,

 

My MSI GTX 770 has recently encountered a issue where the fans will begin to spin up and down creating a ton of noise while the card is getting little use but does not do this while running games. I have tried setting a custom fan curve in MSI afterburner and forcing a set speed but this does nothing unless I set a speed above 70% where it will hold that speed fine. The GPU is clear from dust and the temps are fine around 25c idle. I also used DDU to uninstall the driver which actually fixed the problem only for it to instantly start again the second I installed the Nvidia driver again. This problem also does not happen in Linux running from a LiveCD so I'm assuming there is something happening within Windows but  I can't figure out what.

 

If anyone here can help or advise what I should try it would be really appreciated.

 

Other specs.

Mobo: MSI Krait edition Z97

CPU: i7 4790K (stock speed)

RAM: Samsung 1600MHz DDR3 - 16GB

PSU: Corsair RM750

OS: Win 10 Pro x64

This is actually a common problem with cpu's as well. The thing you're looking for isn't the temperature that your fan's spin up, or slow down at, but the delay.

 

If your fans spike for a second with no delay, then you'll get a constant ramp up noise, and slow down noise. What you're looking for is a few seconds delay between a new temperature registering, and your fans changing speed. This will give time for a bad value, or a temporary increase in load to clear before your computer overreacts to a temporary condition.

 

Be aware however that this will slow down your computers response to a genuine emergency.

The fans spike up to around 2500RPM for a bout 2 seconds and then drop again and it does that in a loop. Looking at the temps in MSI afterburner when it does this they were below 30c the entire time with the temps fluctuating 1-2c at the most.
