"Tuniq's Tower 120 Extreme is an enthusiast grade heatsink that cools very well, pretty quietly. In fact I'll save you the suspense and tell you straight up that it tops Frostytech's Intel reference chart and that it's one of the Top 5 best-ever heatsinks tested on Frostytech's AMD reference chart to date. The 152mm tall Tuniq Tower 120 Extreme heatsink weighs in at about 775 grams and is compatible with Intel socket 775/1366 and AMD socket 939/940/AM2/AM3 processors. The claim to fame is of course its integrated 120mm fan which is not visible from the outside. "
