Gelid Solutions Tranquillo CPU Cooler Review
 

As part of Gelid Solutions Silent line-up, the implication is that the Tranquillo will be silent. In that respect, the expectation has been met and exceeded. One of the compliments I can bestow on this cooler, is that my son walked into the room and asked what was broken since it was so quiet in the room. Kind of an eye-opener once the white noise of high CFM fans used in air cooling are no longer there. Performance enhancements for the Tranquillo will be limited to adding a higher CFM fan to increase the cooling capacity of this cooler, since running a second fan on the back side is not supported due to its 'v'-shaped design. But then you step away from the concept of the Tranquillo.
