Arctic Cooling has just announced a low-profile version of their Freezer 7 CPU cooler for the Intel platform; this designed primarily to suit slim cases, HTPCs etc.
The cooler is just 53mm high (with fan holder) and uses an 80mm PWM controlled fan with a speed range of 600 to 2000RPM. The heatsink itself makes use of dual heatpipes and a patented fan holder that is designed to help eliminate the humming noise.
Head over to Arctic Cooling's website for further information.
Apart from its lightweight and low profile design, the Freezer 7 LP also performs excellent cooling execution. Two heatpipes, 40 fins and an 80mm PWM fan dissipate heat from the CPU core efficiently and rapidly. Together with the highly thermal conductive pre-applied MX-2 thermal paste and voltage regulator cooling, the Freezer 7 LP is 20% cooler (thermal resistance) than the generic E8500 low profile cooler, giving media centre users an unexpected cooling experience.
