FrosyTech posted a review on the Coolermaster GeminII S Heatsink

In this review Frostytech is evaluating the Coolermaster GeminII S - a low height, lower noise, down-exhaust heatsink for Intel socket 775 and AMD socket 754/939/940/AM2+ processors. Coolermaster's GeminII S heatsink stands just 88mm tall and ships with a 120mm fan mounted to its frame. An extra set of brackets allow that fan to be replaced with two 92mm or 80mm fans; say if you want airflow blowing directly down onto adjacent memory slots. The GeminII S heatsink weighs 560grams, features five 6mm dia. copper heatpipes and cooling fins that descend to the CPU base.
