Hi guys,

2 days ago I reformatted my computer and reinstalled windows.

Today after logging in to windows (a few seconds later, network and audio icons appear first) then the CPU fan (not case fans) will run fast/loud as if the PC is under load - even though its idling at 5% CPU usage and 50 degrees celcius (122f). It works normally in safe mode.

This started to occur yesterday at the same time as an odd error message I received from Gigabyte Easytune 6 which was installed but I had not been using. I then uninstalled Easytune 6 using Revo Uninstaller Pro and restarted. That didn't solve it, I did a system restore to the oldest point possible which only brought back the Eastune error message. I then uninstalled Easytune again.

I checked inside the PC, almost as clean as new. Checked connections, all good.

I checked the fan settings in the BIOS which was set to auto for fan speed, tried changing the CPU to PWM (My case fans are Artic Cooling PWM fans.)

Flashed BIOS to latest version.

Used autoruns to check what drivers are running at startup, disabled grdv.sys from Gigabyte.

I am stuck and don't want to reformat and reinstall again! Please help!

It may not be exactly what you're looking for, but I think it's very similar. Good luck :)

Scratch that - it isn't the CPU fan - its the VGA Fan!

ATI 6800 series. Reinstalling drivers now.

Thanks Mike, i just reinstalled the ATI drivers to no avail, but when i went into the CCC control panel - AMD Overdrive, I could see the fan was running at 50% with auto speed enabled. I checked manual speed, applied, then changed it back to auto and it is now running at 25%

Odd, something caused the fan to stick at 50% but it appears to be normal now.

That actually does happen from time to time with ATI video cards, its an odd bug, experienced it a few times myself. If its running fine now, I wouldn't be to concerned about it unless it starts it up again. The one thing to monitor is to make sure the auto speed control turns it up under load like its supposed to. If it does it again, try using a third party fan controller such as Riva Tuner and see if that solves the issue.
