Igloo 3300 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. The fan has been placed slightly 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 sort of of to one side, rather than directly over the area in contact with the processors core (but not by much). 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 pre applied thermal paste. In this case, the Igloo 3300 features 'silver' based thermal material. The entire base has been milled flat prior to plating and this means the surface is fairly well finished.
