Zalman CNPS10X Extreme

Zalman is a very well-known name around the cooling industry because they were the first to begin using copper materials in their product while everyone else was still cutting corners with aluminum. The other factor which has helped add to their success is their promise to deliver good performance without all of the noise. Most all of the Zalman CPU coolers I've tested have been very quite, some completely silent, and performed as well as the very best (noisy) products.

In this article the Zalman CNPS10X Extreme introduces the PWM Mate fan speed controller, so you can fine tune the fan speeds for the optimum balance between cooling performance and noise level. The Zalman CNPS10X Extreme includes compatibility with AMD socket 754, 939, 940, AM2, AM2+ and AM3 platforms, as well as the Intel LGA775, 1156 and 1366 platform. At the time of this writing, the Zalman CNPS10X Extreme was available at NewEgg for $79.99, while others had stock for $67.99. This price is among the highest we've seen for CPU coolers, and it's worth comparing the alternatives.


Five nickel-plated copper heat-pipe rods are staggered and span from the polished nickel-plated mounting base up into the aluminum finsink. The heat-pipe rods and finsink are cooled by a Zalman PWM 120mm Blue LED Fan. The Zalman CNPS10X Extreme includes PWM Mate, the world's first RPM-controllable PWM fan speed controller, with the option of 3-Speed Auto or Manual Control modes.

A polished nickel-plated 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. The Zalman CNPS10X Extreme includes a large syringe of the new high-performance thermal grease ZM-STG2, which maximizes heat transfer from the CPU to the base of CNPS10X Extreme for improved cooling performance. Benchmark Reviews recently tested the ZM-STG2 thermal compound in our 80-way Thermal Interface Material Performance Test.

What was the backing plate you used on the Prolimatech Megahalem . Was it the Xigmatek ACK-I5361 Intel Core i7/Core i5 compatible Bracket Set or Xigmatek ACK-I5363 Intel Core i7/Core i5 compatible Bracket Set

The ProlimaTech Megahalems has its own backplate that comes with the heatsink, and is far superior to the Xigmatek versions. Take a look at the full review that's linked in this article.

If I buy the Megahalems will I need the backplate if I'm going to use it on a 1366 Socket?

The 1366 backplate is already included in the kit.

I mean will I have to use it or it will go on to the 1336 socket without the backplate?
