Cooler Master V10

When I first heard Cooler Master mention how large their V10 CPU cooler was during the 2009 CES, I immediately envisioned a product of Mack truck-sized proportions. It turns out that my imagination actually came pretty close to the real thing, and since the RR-B2P-UV10-GP SKU is easily the largest thermal cooling solution Cooler Master has ever offered the retail market it seems the V10 name is quite fitting. The V10 is the largest CPU cooler Benchmark Reviews has tested, and the 9.32" x 5.11" x 6.36" dimensions push it well outside of the standard confinement of most ATX coolers.

Cooler Master has included everything but the kitchen sink on the V10, and if they thought it might be helpful then the sink would be there too. Weighing in at 2.65 lbs, the Cooler Master V10 is also the heaviest CPU cooler we've ever handled. There are a total of five heat-pipes running through the V10, creating ten heat-pipe ends for enhanced cooling performance. As of March 2009, the Cooler Master V10 was sold at NewEgg for $139.99.


At first, I thought that maybe Cooler Master decided on the V10 name as a reference to the extended cylinder engine; especially since they released the V8 cooler just a few months ago. In reality, I have a feeling that the ten heat-pipe ends are more involved with the name than the shape, since the RR-B2P-UV10-GP model really doesn't resemble too many things I'm familiar with.

Something I am familiar with is Thermal Electric Cooling, or TEC. The principle behind TEC coolers (also known as a "Peltier" coolers) is a solid-state active heat pump capable of transferring thermal energy from one side of the device to the other. Peltier Coolers have been around for quite some time now, based on the Peltier effect. The Peltier effect is the reverse of the Seebeck effect; a creation of a heat difference from an electric voltage. Using the Peltier effect, Cooler Master has created a cooling device which can force heat away from the CPU faster than it could travel by its own means.

The Peltier effect occurs when a current is passed through two dissimilar metals or semiconductors (n-type and p-type) that are connected to each other at two junctions (Peltier junctions). The current drives a transfer of heat from one junction to the other: one junction cools off while the other heats up; as a result the effect is often used for thermoelectric cooling. This effect was observed in 1834 by Jean Peltier, 13 years after Seebeck's initial discovery. Peltier coolers are also called thermo-electric coolers (TEC).


The Cooler Master V10 control unit does not apply power to the TEC modules unless the CPU reaches a certain temperature. Up to this point, the CPU is cooled by the heat-pipes on the "cold" side of the TEC. Once the CPU is hot, power is applied to the TEC and the CPU is chilled. The hot side of the TEC is cooled by the second set of heat-pipes. This perfect balance of thermo-electric cooling and heat-pipe cooling ensures the CPU is kept at the perfect operating temperature. Ideal for hardcore cooling, Benchmark Reviews will discover the potential advantages over standard air cooling solutions.

Had one of these and whilst they work well the fans didn't last more than a year, first one went down and then the other a few weeks later.
