"In this review Frostytech will be testing Coolermaster's Hyper 212 Plus tower heatsink - an exposed heatpipe base cooler that comes ready out of the box for socket 1156 Intel 'Lynnfield' P55 motherboards. Coolermaster's Hyper 212 Plus heatsink stands 161mm tall, weighs in at moderate 626 grams and packs in four exposed 6mm diameter copper heatpipes on its base. Otherwise the Hyper 212 Plus is a pretty standard 'tower' heatsink. A 600-2000RPM, 120mm PWM fan is supplied with swept-forward impeller blades. Between the fan and aluminum fins of the heatsink are vibration absorbing pads to cut down on rattling noises."
