The Glacialtech Igloo 5610 PWM is a compact LGA775 Intel heatsink suitable for office work computers. It's 80mm fan is Pulse Width Modulation compliant, so Intel motherboards can direct it to spin only as fast as required (from a low 800RPM to moderately audible 3200RPM), thus keeping unnecessary noise down. The Igloo 5610 PWM is comprised of two heatpipes, a small section of extruded aluminum heatsink and a short array of aluminum cooling fins. A very simple CPU cooler, and one that is priced in the $10-$15 range making it cost effective for office PCs.
