Summary: The Zalman CNPS10X Optima heatsink is a fairly standard tower cooler in most respects; it offers pretty good thermal performance, accomodates a front and rear fan and has an exposed copper heatpipe base.
Summary: The Cogage TRUE Spirit did an excellent job keeping our Core i7-965 cool, even besting its bigger brothers, the Thermalright Ultra-120 / eXtreme . Its reduced airflow impedance seems to allow the heat radiating off the heatsink to be blown away more quickly. However, we suspect these design aspects would harm its performance when working on a hotter processor, a situation where the total heat dissipation area is more important.
Pros: Excellent performance at both high and low fan speed, Solid, bolt-thru mounting, Price, Excellent performance at both high and low fan speed, Fan controller included
Cons: Support for only one socket (one model for LGA775, one for LGA1366), Stock fan has poor acoustics, Backplate for LGA775 installations only, Mounts facing upward on AMD boards
Excerpt: The Zalman CNPS10X Flex follows a slightly different path than other CNPS10X models. When compared to other CNPS10X models, the fans are not included and the heatsink is now able to take full advantage of two fans.
Excerpt: Zalman's heatsinks have carved out their own path in the CPU cooling market and turned what used to be large chucks of aluminum and copper and into stylish, modern, and functional works of art. Their new CNPS10X series has been very impressive and we saw low temps when we reviewed the original CNPS10X Extreme last year. So, when they informed us they were adding a new member to the group called the CNPS10X Flex, we had to get one to test in our LGA 1156 test bench.
Summary: The Zalman CNPS10X Flex heatsink ships without any fans, so users can install one or two 120mm fans of their own choosing. In all other respects the CNPS10X Flex is identical to Zalman's CNPS10X Quiet heatsink, so today's review is not going to be a huge departure from what we saw from the Quiet.
Summary: When we tested
a few months ago we were very impressed by its rock-solid aspect and by its performance. Today testing its "little brother" we also liked the results. Although CNPS10X Flex is not as beautiful as its most expensive brother - at least in our opinion, but taste is a very personal matter -, it performed practically the same as the other model.
Summary: The Zalman CNPS10X Flex has some inherent advantages over the more extravagant CNPS10X Extreme . It sports a lower price-tag thanks to its lack of the Extreme's nickel coating, fan controller and loud stock fan. In addition, the mounting system has gone through a much needed overhaul. The Extreme ships with a several sets of mounting hardware to accommodate the different CPU sockets, lacks a backplate for LGA1366, and points the fan upward on AMD boards.
Pros: Simple and secure multi-socket mounting system, AMD mounts in the "proper" orientation, Good high airflow performance
Summary: When you open the box of the CNPS10X Flex its pretty tough to get too excited as its only a heatsink, but once you get this cooler equipped with a couple of your favorite 120mm fans and see the performance that this cooler offers its a whole lot easier to get excited about the CNPS10X Flex (or about as excited as you can towards a CPU cooler).
Pros: Good Performance, Support for 2 120mm Fans, Compatible with all recent CPU's
Excerpt: The Zalman CNPS10X Quiet cpu cooler can be summed up to be a quiet winner. Although the installation was a little daunting, the performance after the fact made this cooler worth the effort and frustration. It beat everything with ease and could even be used for mild overclocking if temperatures are monitored and the speeds adjusted for the fan's capacity.
