Hi I just got my Powercolor X850XT @PE =D When I want to control the fanspeed and set it to "Override fan speeds" and "Dynamic based on GPU temerature" I get a high sound from the fan. =( Even if I check the fan speed % before changing it and then sets the "Fixed percentage" to the same %, I get the same high "light" sound! It doesn't matter what I set the percent to because the sound is on every percent. =( I don't have this sound in default settings at any fanspeed, only in ATITool. I have the latest version...and I tried 0.24 Beta 1 to..same problem. Should the temps really be that high set in Dynamic based on GPU temerature? 17% @ 91 degrees?
