Am going use my air compressor to blow any dust off after work today (It was to late & dark to do it last night)Have they got some dust on them and good airflow? Or is it just crysis 3. .

I just notice one of my GTX 580 temperatures is at 98c while playing crysis 3..
That most be very close to the temperature were the card auto downclocks..
MSI Afterburner, set up a fan control profile. Can't recommend this enough.
My 680 doesn't go over 67 at max load.
