ah thxdidnt notice it had fan settings...!
Right just tried crysis at my stock fan speeds and yea it was on 25% fan @ 700/2000/1750 and the temp was going to 88 degrees. I've set fan speed to 50% now and i can hear it a little more but certainly not so it'd bother me and its now 78 degrees max so that'll do me nicely.
Use fan profiles mate. there is a nice tutorial on how to create them, and its so easy ( I could do it and I am kinda new to useing advanced rivatuner)
also, once you have done it, reboot pc to get it to work, and rivatuner has to stay open, don't close it afterwards.
