Not Much Room Around The CPU: ALPHA FC-PAL15
First of all, the FC-Pal15 has been designed especially for PCs that don't leave much extra room for a CPU cooler.
Considering its low profile of a mere 25 millimeters, its cooling capabilities are nothing to sneeze at. But it would be rather overwhelmed trying to cool an overclocked processor. We would prefer not to plonk it onto a gigahertz Athlon.
The base plate of the FC-PAL15 consists of aluminum and contains the copper inlay that comes standard on Alpha coolers to improve heat distribution and dissipation. Like the large Alphas, this cooler has hexagonal pins made from aluminum pressed into the plate to increase the cooling surface.
