Best LGA 1700 CPU Cooler For 2U Server System

Aluminum zipper fin stack

Aluminum zipper fin stack is manufactured by stamping sheets of aluminum and with interlocking features as designed, aluminum alloy is one of the most common meterial of heat sink as its cost-efficient, lightweight, and great thermal conductivity, but most importantly, aluminum has excellent thermal dissipation performance which is even better than copper, so it typically used to be the material of zipper fin stack. Aluminum zipper fin stack is usually soldered with heat pipes or vapor chambers to dissipate the heat transported by the heat pipes or vapor chambers. aluminum zipper fin can be manufactured with a range of geometrics and thickness. The stamping fin technique provides high production efficiency, high aspect ratio, lightweight, and good thermal performance. 

Heat pipe direct contact design

Heat pipe is one of the most effective cooling device, which is composed of a sealed tube, wick structure and working fluid, heat pipe is a two phase cooling components which utilizes vapor and liquid phase change to transport the heat. This CPU cooler uses 5 heat pipes and the heat pipes are contact with CPU directly, this design significantly reduced the thermal resistance between the CPU and heat sinks, the heat can be conducted to heat pipes directly and then be transported to the aluminum fins, this design makes the heat conduction and transportation faster, so the thermal performance is greatly improved. Also the copper pedestal is not needed, which can save some cost.
