Optimized CPU Cooling Performance with Top-Down Heatsinks

Admin Topics 199

A few years ago, back when I was busy publishing my guide on the Best Thermal Paste Application Methods, I noted the performance difference between heatsink orientation. That is, the physical direction of the heatsink and heat-pipes in either the vertical or horizontal position. What I missed was the difference between tower U-style heatsinks and their down-facing C-style counterparts. While I’ll be using the Cooler Master GeminII S524 Ver 2 heatsink to illustrate my points, the benefit of each style will be the focus of this article.
