The Gelid Tranquillo heatsink stands 153mm tall and ships with a single 120mm PWM fan mounted. The tower-style heatsink weighs 645 grams and is compatible with Intel socket 775/1156/1366 and AMD socket 754/939/940/AM2+/AM3 processors.

While you might expect the Tranquillo to be an exposed base heatpipe heatsink, it is not. Instead the four copper heatpipes are grouped closely at the base on a small copper heatspreader, and also grouped relatively closely to one another where they pass through raw aluminum cooling fins.
