Luckily for us, power supply manufacturers have begun to release low noise units - so the last frontier of a noisy PC is finally being cracked. It's no surprise that Zalman has launched a low noise power supply of its own, and no surprise then that the 600W unit packs in components from a standard heatsink to augment its cooling capabilities.

At the heart of the Zalman ZM600-HP is a short length of heatpipe that connects part of the power supplies' power circuitry to a compact aluminum heatsink fin array. The aluminum fins take the place of a second fan, and those horribly inefficient power supply heatsinks... well for the most part. More on this in a bit.
