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.
Conclusion: The Zalman CNPS10X Flex is certainly worth considering for LGA1366 CPUs. On LGA1156 or Socket AM2+, the cooling power of the heatsink was comparatively poor no matter which fan we used. However, on LGA1366, the Flex was more interesting.
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.
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.
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...
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.
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...
Pros: Good Performance, Support for 2 120mm Fans, Compatible with all recent CPU's
