Hi i have a 290x water cooled idle around 30-40c depending i fi have 2 monitors connected and around 60c underload, any way today i noticed on afterburner it said max temp had reached 146C 
Its been left on over night so dont know when it happed, luckily GPUZ was running as well and it also max temp was 146C so it wasn't an afterburner fault.
So can a card give a false reading because im using it underload and its still not going much over 60c!
I have to point out that when i looked at the temps they were fine, it was just reporting it had at some stage reached 146c
Thanks
