Dec 17, 2012Martin Reviews the PMP-500 Pump
The PMP-500 does most things outstandingly well. It has a great price, build quality, g1/4 barb compatibility, built in heat-sink, and about double the power of the PMP-450 all while actually getting smaller in size. The hydraulic performance is nothing short of amazing and can push through pretty much any build out there... King of 12V single pump performance.

Astonishingly, the Koolance CPU-380 outperforms all of today’s top blocks in both single and dual pump configurations... Koolance’s CPU-380I is an all-around great water block that has a sleek and robust design... Overall there’s a lot to like about the Koolance CPU-380I.
