Information on Frostytech's test methodology is available here.

The 120mm PWM fan on Zerotherm's Nirvana NV120 PWM heatsink is illuminated with a pair of blue LEDs and rotates at speeds of 900-1800RPM. Dense foam padding behind the fan motor prevents rattling sounds from occuring between the free standing blower and heatsink fins. Power is supplied by a 4-pin PWM motherboard fan header. The Nirvana NV120 PWM heatsink stands 145mm tall, 128mm wide and 90mm deep. From the rear you can clearly see how the fins overlap to create a rudimentary honeycomb shape.

The side fins of the Nirvana NV120 PWM protect the 120mm fan impeller from errant wires. The fins behind the fan are 61mm deep, split into three 20mm sections. These are alternatively bent up/down 10mm. The base plate is nickel plated copper, set within an aluminum frame that the mounting brackets attach to with a couple screws. There is 40mm clearance below the lowest fin for adjacent motherboard components.

Four U-shaped 6mm diameter copper heatpipes pass through the aluminum fins, and the entire assembly has been nickel plated. At the base the heatpipes are packed edge-to-edge to ensure good thermal transmission from the 3.5mm thick copper base plate. Each aluminum fin is 0.3mm thick and spaced 2.0mm apart from the next. The Nirvana NV120 PWM's base measures 32x30mm in size, and is 3mm thick on average. The entire heatsink is nickel plated, giving it a dark glossy surface for fingerprints to show up on.
