270 msi max temperatures.

Solution
The new R9 line sets it's temperature target to 85c, so that's fine as long as it occurs when you're stressing it to 99-100%. The GPU will overclock based on the temperature, and won't throttle down the overclock until it hits 85c. You can increase the speed of your fan if the heat is bothering you though.
