So, I got a HIS Radeon HD 6770 IceQ, and have been messing around with MSI Kombustor. Then I ran the furry donut test. And within 10 seconds, the core temperature has been rising from 50 degrees Celsius to a whopping 105 degrees celsius. My question is, is it normal for the card to get that high, and what's the max temperature the card can handle without any artifacts, or worse, crashes?
