Well of course it depends on the model. My powercolor runs HOT! There is a solution though. The accelero x2 isn't work getting for the simple reason that it doesn't blow the air out. The stock cooler on most will do a fine job cooling however you have to tweek the settings. If you use ATITOOL then you can change the fan speed settings which aren't available with CCC (Catalyst Control Center). The one that I found to like the best is the option to change during different temp ranges. See, at least for the powercolor, the fan doesn't rev up until it hits over 75 c. My powercolor ran way hot. They wanted a quiet card but the problem is that it severely increases the ambient system temp. Use ATITOOL and you are set.
