Temperature testing is vital because if your Diamond Radeon HD 6770 XOC Graphics Card gets too hot it could cause the Diamond Radeon HD 6770 XOC Video Card to stop working. As we all know heat is the mortal enemy of computer components. To test the Diamond Radeon HD 6770 XOC I ran Aliens vs Predator until the Diamond Radeon HD 6770 XOC Video Card was at 100% load and left it for one hour. The idle temperature was also done the same way, the Diamond Radeon HD 6770 XOC GPU was left at 0% load for one hour.

As you can see the Diamond Radeon HD 6770 XOC Video Card is one of the hottest running cards that I have tested to date. It idles at 56 degrees which is 14 degrees higher than the next highest temperature and it’s load temps were even worse coming in at almost 90 degrees. It actually caused the room I was in to rise in temperature significantly. Since the temp were so I high I decided to remove the stock thermal grease and apply a high end thermal grease to see if there was any difference. Well, there was and it was a big one. The Idle temps dropped down to 50 degrees a six degree difference, but the most drastic change were the load temps coming down a full 17 degrees to 72 degrees. I don’t know what type of thermal grease Diamond is using, but they need to change it. 89 degrees is way too high.
