The MCX-4000 continues the Swiftech tradition of using helicoids pins. This helicoid pin design increases surface area for heat dissipation. This design is also supposed to increase air turbulence for more efficient heat dissipation compared to traditional fin design. Maybe it’s just me, but I can’t help thinking of the oxygen reactor from Total Recall when I look at this.
The copper base measures 3/8" thick. The center part is the heat spreader, which is the part that actually makes contact with the CPU. The heat spreader has been machined flattened to 0.001", and a micro surface finish 8 (or better). It’s about as attractive as a heatsink gets, with a nice mirror like shine. The twin sets of holes allow the MCX-4000 to accommodate both 70 and 80mm fans. As always, an 80mm fan will provide the best performance.
