Today we'll be looking at another iteration of Coolermaster's popular 'Aero' line with the very unique blower fan. The Aero 7 Lite is an "Aluminum extrusion with copper inserted" type heatsink. The idea is that the copper draws more heat from the CPU die, and the aluminum disperses it. Those of you familiar with HSFs will be familiar with this concept. The benefits of this design is that while the temperatures may be slightly higher then an all-Cu design, the heatsink itself will be significantly lighter.
