there might be dust in the heatsink, or the heatsink is loose and not making a proper connection to the gpu chip...
If it is loose, the thermal paste has already cured because of the heat, so you need to take it apart, remove/clean the old paste from the chip and bottom of the sink, apply some new paste and screw it back on...

What is the make/model of your PSU?

Which coolermaster case did you get?

I agree with kari, it's probably dust or thermal paste.Just to give us a better idea download HWMonitor and post back what your GPU temps are at load and idle.

As mentioned, download this:

You can check your card's temps with it. If it's getting up to 98 - 100 degrees C that's the issue. Blow out the cards heat sink, and if necessary, reapply thermal compound.
