Case fans running at 100%

[imginy]

Hi guys I asked in general hardware as well.

Recently my case fans have started running 100% in windows and I don't know how to fix it. The pc runs silent in bios but as soon as windows loads my case fans hit 1200 rpm and changes I make in bios are not making a difference.

My temps are all low idle at 29c cpu (600rpm fans) and 39c gpu (0% fans)

I had this case for 3 months and it was always silent I done a couple of updates recently windows and nvidia driver so not sure if they caused it.

Check the motherboard software, should be able to control the pwm from there

I had never used moptherboard software before so I took your advice and downloaded the gigabte app center and installed the system info viewer that says it controls fans but none of the controls do anything to my fans.

The gigabyte app seems really bad tbh.

Im still stuck at 100% case fans.

Right so I have found a temporary fix on this webpage it seems it's an issue with the gigabyte boards http://forum.gigabyte.us/thread/2413/system-fans-full-rpm

I need to put computer to sleep and wake it up again every time.

@GIGA-Man is there a fix for this?

No idea why an update would've changed that though. Unless Windows is sensing some temps incorrectly (??!!)

I had thought that my self so set fans to run it off cpu temps instead but no difference as soon as I hit windows my case fans run 100%.

As I mentioned above I have temporary fix now.

Could do with permenant fix though if you can think of anything. I suppose a format or buying a fan controller would do it but hopefully there is a simpler fix.
