Zalman ZM600 heatpipe-cooled modular power supply
 

As power ratings grow larger, power supply manufacturers struggle with the battle of heat dissipation. The common method of tackling this problem is by using standard heatsinks and fans. Zalman brings another idea to the table — not necessarily a new one, but one that proves to have some merit — heatpipes. SilverStone used this idea with their ST30NF Fanless PSU, and came out with a pretty decent product.

Zalman is a company better known for their heatsinks and other cooling technologies, and with the ZM600-HP's power output and price tag, it looks like they're taking a shot at the high-end power supply market. Zalman is no stranger when it comes to using heatpipes, as we saw with the TNN-500 and the TNN-300 Fanless PC Enclosure System SPCR reviewed in February 2006. Heatpipes offer an effective method for transferring heat from one area of a system to another, provided that the temperature difference between the two is great enough.
