Overclocker Cafe checks out a budget
heatsink, the Thermalright SK-6+.
In this narrower SLK configuration, the air from the fan, blows through
the fins directly onto the mainboard keeping the hot stagnant air from just
sitting there keeping the base warm. The thinking behind the more traditional
SK squarish base is that the additional metal will help pull heat
laterally away from the processor helping to evenly distributive the heat along
the length of the cooling fin.
