Glacialtech, known more for its OEM-replacement and value-ended CPU coolers, sometimes takes the time off to release audaciously-designed performance CPU coolers, such as the UFO V51. It seems to be the case with the Igloo 5751 PWM, the latest in the making. The Igloo 5751 PWM uses a CPU base in which four 6 mm thick heat pipes make direct contact with the CPU, capped with an aluminum heatsink, with the heat pipes conveying heat to an aluminum fin array that propagates along the plane of the motherboard, covered with metal plates on four sides, and two 92 mm fans on two.

It measures 100 (W) x 135 (L) x 130 (H) mm, weighing 550 g. The fan on the top spins at 1400 rpm, while the one on the bottom spins at speeds between 800 and 1800 rpm, controllable by PWM. The Igloo 5751 PWM supports all current CPU sockets, including LGA1366, LGA1156, AM3/2(+), and LGA775. A tube of Glacialtech IceTtherm II thermal compound comes bundled. The company did not give out a price, though one can expect it to be moderately priced.
