Overclocking

The i7 3960x is stock clocked at 3.3GHz. In order to achieve 4.8GHz clock speed, the CPU was liquid cooled with a 360mm radiator using a push-pull fan configuration. The MOSFETs that make up the VRMs are also cooled in series with the CPU. The main limitation on the clock speed is the VRM cooling.

Future Upgrades

To combat the VRM cooling issue, it is planned to add a second VRM waterblock on the reverse of the board, thus sandwiching it together between 2 waterblocks. The pump will also be upgraded to a Gorman Rupp Industries INTG2 running on 12V. The radiator will be replaced with 2 high density copper radiators, both in a push-pull configuration.
