GPU Fan Spins Up and Down when Idle

firedragon852 · Jan 24, 2016

I have an ASUS GTX 750 OC 1Gb video card, BIOS version 82.07.32.00.31.

The GPU fan spins up and down approximately every 10 seconds even when the video card is completely idle. In GPU-Z, the Fan Speed (RPM) reading goes from 0 to 3000 RPM every 10 seconds even when the Fan Speed (%) is constant at 22%. When the RPM reading is over 3000 RPM, the GPU fan becomes extremely loud.

If I boot to the BIOS instead of Windows, the GPU Fan does not spin up and down periodically.

This same problem exists in both Windows 7 Ultimate and Windows 10 Pro.

Nvidia driver version is 361.43.

Please help and let me know what I need to do to stop the fan from spinning up and down when the video card is idle.

whys it showing as 1050MHz? thats not idle

It looks to me as if 30celcius is the diving line for your fan to kick on and off, since J see the fan spimes, and also 30C strsight through.

Have you considered a fan profile, using say, Afterburner, or Precision? It's worth trying a 6 to 8 point fan profile and see if it fixes it.

This is a factory overclocked version of the GTX 750 video card.

Tried both MSI Afterburner and Asus GPU Tweak 2. Defined a custom fan curve but for some reason the video card spins up and down the fan and ignores settings in the fan curve.

at idle shouldnt it drop below those clocks? could be causing more heat, and therefore the fan spinups.

The GPU fan spins up and down with or without a web browser open.

firedragon852 · Jan 24, 2016

The strange thing is when I am playing a game eg Far Cry 4, the GPU fan stops spinning up and down.

Normally I don't mind the GPU fan spins but it's quite annoying to hear the loud fan noise every 10 seconds.

Try to force a constant RPM via Afterburner, try 40% or 50%. Does the fan still revving up and down?

Yes it does.

Hmm.. that's strange.

Try to increase the speed bit by bit starting from 50% until it reach 100% fan speed. Maybe using 10% increment.

Does it still revving up and down? If not, at what speed does the fan stop revving up and down?

Beertintedgoggles · Jan 24, 2016

Since it doesn't do it in BIOS and you said forcing constant fan % still has spin ups and downs... can you try completely removing the drivers and reinstalling them? For completeness, try a fresh install of windows on the system. I saw you mentioned it does it in both Win 7 and 10 but I'm not sure how Win 10 was installed (if you updated the Win 7 install to 10 or did a fresh install).

The strange part to me is that the fan % is not shown as increasing and decreasing yet the fan RPMs report exactly what you are saying is happening.

Windows 10 Pro was installed fresh. Also tried using DDU in Windows 7 to completely reinstall the NVIDIA driver. The problem still exists.

It does for fan speed below 70%. If I set the fan speed to 70% (manual control), the GPU fan does not spin up and down.

Does it ever change temperature? Your first GPU-Z shows a constant 30 C. The sensor could be broken.

Yes the temperature does change in GPU-Z.

GreiverBlade · Jan 24, 2016

btw... 1050mhz indicate a load not that it's a factory OC ... i.e: my 980 off load is at 639mhz idle and it's clocked 1279mhz off boost and goes round 1415+ on boost ... you have something running that use the GPU probably, oh and try to edit your post rather than double post

so yes normally

it would do that

It could be power delivery from PCI-E slot that causing this, have you tried forcing the PCI-E to always run at performance mode?

NVIDIA Control Panel > Manage 3D Settings > Global Settings > Power Management Mode > Prefer Maximum Performance

GreiverBlade · Jan 24, 2016

oh... and can you list your system specs just in case (and fill your sys specs also in your user control panel at the same time )

also non idle :

can't shot a idle now but even the vRAM lower speed on idle, your's show it does not.

now that's idle, altho don't double post: there is an edit function on the bottom left of your post, thanks.

you might want to consider a RMA if the card is still under warranty and nothing else do.

vega22 · Jan 24, 2016

go speak to asus, might need a better bios.

^This^

Try the card in another system for a while to test... if you have no way of doing this then try running it under a Linux version (this will eliminate windows as a problem).

See if your fan on the card spins easily while off. Make sure it is not binding in any way.

Okay - I think the case is solved - just got an email from GAINWARD Support:

Hi,

This sounds you have a card with a defective chipset fan control.

The fans are controlled from the chipset after the driver installation because the 770 card has GPU Boost 2.0.

A defective chipset fan control is not repairable.

You will get an exchange card.

Please contact your reseller Komplett to start the rma procedure.

Thanks all fo trying to help

Your card, too, seems to have GPU Boost 2.0 according to the ASUS site.
