Zalman CNSP7000A-Cu Heat Sink Review



Last month I took a look at the CoolerMaster Aero 7+ heat sink, which brought forth a new unique design. Today, we'll be looking at a new heat sink from Zalman, who as many know also have a unique design of its own� H U G E. For those of you who complain about your computer noise, read on, as the CNSP7000A-Cu heat sink is something you are really going to like.

Zalman is, as far as I know, the only company that specializes in producing low noise cooling devices for computers. Zalman's Computer Noise Prevention System (CNSP) technology, can reduce computer noise to 20 dB(A) or lower, which is blow what most people would even notice. This is excellent for those looking to build a hi-fi system out of a PC, or even for those who sleep with the computer in the same room.
