Zalman CNPS9300 AT

When Benchmark Reviews corresponds with manufacturers to request product test samples, we ask them for the very best CPU cooler they make. So when Zalman accepted our request, they sent the Zalman CNPS9300 AT to represent their interests. At first, I must admit there was a little aprehension. First I had to get over the fact that the Zalman CNPS9300 AT was such a small cooler. But here at Benchmark Reviews, we like to leave no stone unturned.

A proprietary mounting system utilizes a bolt-through kit with a brace-arm clamping the CNPS9300 down with ample force. Designed for Intel 775 and AMD AM2+/AM2/754/939/940 socket mounting, the Zalman CNPS9300 AT is ready to cool practically every CPU made in the past four years.

There are two copper heat-pipe rods spanning from the copper-inset mounting base. The four heat-pipe ends curl around the round-shaped copper fin-sink array, and are cooled by Zalman's proprietary SuperFlo-bearing 92mm fan.

A mirror-polished copper contact surface mates to a metal upper-base segment, with heat-pipes pressed between the two parts. Because of the very smooth contact surface, only an extremely small amount of thermal paste is needed for best heat transfer.
