hd 4890 fan stuck at full speed help!

orthowen · 10-31-2009, 12:20 PM

Help my fan on my msi HD 4890 is stuck at 4600+ rpm. I cant even turn it down in ccc. Infact when check the manual control and hit apply it speeds up. even when set down to 20%. Then when I uncheck it and hit apply it slows back down to 4600 rpms. gpuz shows the speed while ccc a shows the percentage speed at only 7%! it sounds like a space shuttle take off. I took the card out the day before to clean the fan. but i did not dissemble anything. I then placed it back and booted up and everthing was fine. until the next day when I booted up the card spun up immediatly after turning on the power and stayed at max speed.two other things I did that day were flash my bios and upgraded to the 9.10 video driver. but it worked fine untill the next day.any help plz. I can paste any info i needed when i get home from work.

It would appear the driver or bios did it. Try simply reverting back to the old driver or bios first.

The bios is fine, its a known issue for some of the Catalyst releases, try reverting back to 9.8 and see how they work.

Reverting the bios and driver did not work. I will try the CCC next. Right now GPU-z is showing 4500rpm while CCC is showing only 7% load on the fan. Does any one know what the rpms should be at 7% or even 20%? Thanks for the help guys.

The problem is that you need to clean the drivers totally out for anything to do with ATi and then install the entire Catalyst suite, you cant just install the driver and ATi TT and expect the perfect results with these newest Catalyst because half the time you will end up without full acceleration or you will end up with blue screens going on about the memory or something along those lines. All in all you need to have the most recent .NET, DirectX and BIOS and from their you need to test all the different Catalyst drivers from 9.4 on since they were the first with the 4000 series included at full potential. Hope that helps...Cheers!
