Igloo 2400 From All Angles

The nine bladed impeller on this 20mm thick fan only creates about 20CFM of air flow according to the manufacturers specs, but given the small size of this heatsink that should be sufficient. Oddly, the fan has been placed off center on the heatsink as you can see. The fan connects to the motherboard via a 3-pin fan header which supports RPM monitoring.

Top: With the fan removed for a moment you can really see what we meant about he off center placement. This could be a good thing as this places the dead spot of the fan to one side, rather than directly over the area in contact with the processors core. The red aluminum fan shroud does the usual duty of keeping the fan in place, and helping to direct airflow.

Heatsink Base:

I really like these heatsinks which come with a pre applied swath of thermal paste. In this case, the Igloo 2400 features 'silver' based thermal material and not the standard white silicon thermal paste we see everywhere. Base flatness is good, but the surface shows some deep scratches from the extrusion sanding processes. Lapping is recommended if you want to take the time.
