Zalman CNPS10X Flex CPU Cooler Review

Mid-Speed Fan Performance Results

2.6GHz

While not as impressive as the high speed fan results, these are still very good numbers. It may no longer be in the same league as the best HDT coolers out there, but up against other solid base deigned coolers (even ones weighing a heck of a lot more than the Flex) it does trade blow for blow and even beats the Prolimatech.

3.42GHz

With only a degree and a half separating this Zalman cooler from the Prolimatech, we feel comfortable in saying that the Zalman engineers did get it right with this improved design. We really are starting to like not only its flexibility at low and higher heat loads but the fact that it costs significantly less than the CNPS10X Extreme.

3.8GHz

At high heat loads there is such a thin margin between first and fifth that if you are planning on using a single moderate speed fan, then ANY of these coolers would be a perfect fit. Considering the level of competition in this chart, that makes the above statement all the more impressive and we are not only beginning to love this cooler but really come to respect its abilities. It really is the rare cooler which can perform so amazingly well at such a wide range of speeds and heat loads.
