Grandis XE1236v2

The Grandis XE1236 is the pinnacle of SilentiumPC CPU cooler lineup. This dual-radiator monster offers stellar cooling potential for the hottest processors on the market. The performance comes from massive heat dissipation area and the XE Technology, an additional solid copper heat spreader that transmits the heat from the CPU more efficiently to all six Φ6mm U-shaped heat-pipes unleashing their full potential.

The Grandis comes bundled with two exceptionally quiet GF12025 120mm PWM-controlled fans generating only up to 21 dBA at their maximum speed. Also included in the package are extra mounting clips for the third, optional 120mm fan and the high-performance Pactum PT-1 thermal compound. Robust, mounting system using a backplate ensures optimal pressure between the base and the CPU as well as quick and straightforward installation.

Despite the overall dimensions the optimized height allows the cooler to be mounted in every PC case at least 185mm wide. With the ability of cooling down any type of CPU on the market the Grandis XE1236 is an obvious choice for overclockers, hardcore gamers and professionals seeking total silence for powerful PC’s.
