The G5 uses the same basic cooling methodology as the G4, but jet density has increased and a pure silver baseplate was used instead of copper. The middle and top plates are black Delrin (which will not crack), the barbs used on the Storm have a slightly larger inside diameter than normal 1/2" barbs (and are chrome). As with the G4, the cups in the baseplate contain a small pin in their center to increase turbulence.
