Biggest selling feature of this cooler is the low-profile design, and also this cooler is nice and quiet, which is a plus if you're going to use this cooler for a HTPC where noise can be an issue. The fan on the Nano Silencer is also equipped with a PWM-controlled fan, so if the CPU temperatures rise the fan will also spin up automatically. This fan will speed up to 3,000 RPM if necessary, however in all our testing we never saw fan levels go much over 1200 RPM, which is virtually silent.
