EVGA GTX 770 SC w/ACX - Fan speed in % showing wrong value

Recommended Posts

Hello!

 

I just installed my new GPU EVGA GTX 770 SC/wACX replacing my old ASUS GTX 470. Now I have noticed that AIDA shows GPU fan speed in rpm properly but scales it to wrong percentage value. While idling in 2d desktop fan speed % should show 41%. Instead AIDA shows 27% value.

With GTX 470 %-value was OK. All other sensor/measured values are OK.

Make sure to upgrade to the latest beta version of AIDA64 Extreme Edition available at:

 

http://www.aida64.com/downloads/aida64extremebuild2546y3mbp1kvdjzip

 

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

 

If it doesn't help, then please right-click on the bottom status bar of AIDA64 main window --> Video Debug --> nVIDIA GPU Registers.  Copy-paste the full results into this topic. Also, right-click on the bottom status bar of AIDA64 main window --> Video Debug --> nVIDIA SMBus Dump.  Copy-paste the full results into this topic.

 


Thanks,

I installed the latest beta version and rebooted but unfortunately fan speed %-value is still wrong. When idling at min. speed fan speed is 1350 rpm which is 41% from the max. speed.

 

Here is the nVidia GPU register data:

Thank you for the dumps.  Please check it with GPU-Z 0.7.2 as well, and let us know if it shows similar value to AIDA64 or not.

 


Thanks,

We've fixed the GTX770/GTX780 fan duty cycle issue. Please upgrade to the latest beta version of AIDA64 Extreme Edition available at:

 

http://www.aida64.com/downloads/aida64extremebuild2590hs6vgtb9xyzip

 

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

 

Let me know how it works.
