The heatsink itself measures 2.5" tall without the fan which adds another full inch to the height. Fifty-five fins and three large 8mm heatpipes do the brunt of the cooling, while a smaller, thicker, 12 fin heatsink directly on top of the base will also help dissipate a little heat away.
The 92mm fan used is very refreshing to look at - I can't say I've seen a fan with a baby blue frame and white blades before, but I sure like it. This is a PWM controlled fan and is branded as GlacialTech's own (even the center hub has their logo stamped right into it). The fan speeds range from 800-2000RPM, with a maximum airflow of 40CFM and maximum noise level of 27dBA. Although 27dBA is louder than a lot the 120mm fans being used on coolers these days, it actually isn't too bad in comparison to a lot of other fans in the same ballpark as this one. The PWM controlling will also help shave off some extra noise when the CPU isn't at a high load.
