Close to water cooling
The Verax polargate sets new standards for cooling performance and noise development. With an Rth of 0,167 K/W, it achieves cooling levels, which up to now have only been attainable with water cooling systems. And it remains pleasantly quiet. Intel's benchmark demand of 0,33 K/W for their 3,2 GHz CPUs leaves the two fans running below 2000 rpm and hungry for more. Der polargate consists of a cooling fin heatsink with one or two Verax fans. The generated air current passes over approx. 2000 cm 2 of copper surface.
The secret of polargate's high cooling performance and low noise lies in the principle of thermal counterflow. Cooling air and heatsink possess an approximately constant temperature gradient throughout the system. The Verax polargate makes this working principle possible. Cooling begins already at the tip of each fin.
Cooling directly at the CPU
Cooling air reaches the CPU directly. That's where the heatsink is the hottest. The air's cooling potential becomes fully utilized. Ribbed heatsinks do not allow for this, due to the nature of their construction. A hot air cushion is generated above their CPUs, which does not aid the cooling.
Radial fan, diffusor with boundary layer
The Verax radial fan produces an air current with high velocity inside the fins. The heatsink is designed as a diffusor, it converts the energy of the air current into static pressure. A boundary layer is produced on the surface of the smooth fins with the resulting friction guaranteeing a very good heat transfer.
The temperatur-rpm - curve can be adjusted to various settings via a miniature switch, which is mounted on a slot sheet accessible from the outside.
