The bright yellow 140mm PWM fan spins at 1400-700RPM and draws power from a standard 4-pin motherboard fan header. Five 8mm diameter nickel plated copper heatpipes rise up through the 124mm tall aluminum fin stack. Heatpipes are offset 9mm and the pipes range from 105/85/65mm apart. Each aluminum fin measures 0.2mm thin and is spaced 1.5mm apart.

Glacialtech's Igloo H58 heatsink stands 174mm tall, the bottom-most fin being 39mm above the CPU socket for clearance. The fin tower measures 64mm deep, 124mm tall and 147mm wide. The five heatpipes are swaged into a rather narrow extruded aluminum base plate with a flattened oval profile.

The exposed heatpipe base of the Igloo H58 heatsink measures 40x52mm in size. The 8mm diameter heatpipes are swaged in flush and machined very flat and smooth. The four small holes in the fins (top view) are where the wire fan clips lock into position. The plenum behind the fan is 4mm.
