Suddenly the fans on my GPU is going crazy.....(see picture - Fan speed curve) It goes from zero to 3000 rpm and then back to zero and to 3000 rpm again - on and on and on.... It drives me nuts..... The fans are clean - just air-spayed them and temperatures are okay. Gainward has an tool called EXPERTool - the only thing I can control with that is when I set the fans to full speed - but when setting it to Auto or manual to the lowest possible speed it still goes up and down and up and...... I have also tried with EVGA´s Precision X tool - same result.... Any ideas what i wrong ??
