CF 5770 load temps

  1. So I'm running two XFX HD 5770's at 850/1200 mhz, 85% fan speed. Air flow is pretty decent, although the PSU sits a little close to the bottom card. While gaming I'll hit up to 76-77C but never over 80C. I've read a few posts and reviews and heard that these cards can run sub-90C fine, but a lot of these included users running their fan speeds at like 60% or below.

    My question is : Is reaching almost 80C at 85% fan speed too high? Is it safe to run this for 3-5 hours a day/ 7 days a week?

    Thanks for any info/help you can give :)

    If your cards are right next to each other then yeah, they will run pretty hot.

    It's pretty common to see GPUs running at 80-90C and they're designed to take that kind of temperature anyway, wouldn't worry about it too much if I were you. 3-5 hours a day isn't really that much compared to bitcoin miners who run 24/7.
