Zalman CNPS9900DF Heatsink Review

Zalman's CNPS9900DF heatsink is a twin tower cooler that stands 154mm tall and is built around three 6mm diameter composite wick copper heatpipes. For a look inside a composite wick heatpipe, check this out. The CNPS9900DF comes with two fans, a 120mm intake fan that runs at a fixed speed of 1000RPM and a center, 135mm PWM fan than operates at 1400-900RPM.

The six heatpipe ends are laid out side by side at the base and soldered to a thick copper heatspreader which conducts heat from multi-core processors more evenly than exposed heatpipe thermal solutions can. The heatpipes support two 135mm diameter torus shape nickel plated copper fin stacks. Zalman's design is efficient, in that the shape of the small cooling fins harnesses both intake and exhaust airflow from the fan impeller blades. The CPU cooler weighs 900 grams, stands 154mm tall and has a footprint of 136x111mm. Zalman rate this heatsink for a maximum thermal load of 300Watts... but until Frostytech's LGA2011 test set is up and running we have no way of validating this assertion.

Zalman's CNPS9900DF heatsink retails for around $80USD and is compatible with Intel socket LGA2011/1366/155/1156/775 processors and AMD socket AM2/AM3/FM1/FM2 CPUs.
