Abstract: Conversely, the standard socket A versions need only be cut to size, and a space cut for the clip to sit in.

Igloo 3300 From All Angles

The Fan:

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.

Side A: There are no cross cuts in the body of the 89mm long heatsink body and the fins are not scalloped or patterned. The entire heatsink has been nickel plated which has given the aluminum a nice looking finish, but it is hard to say what effect this will have on its heat spreading properties.
Side B:
This very simple heatsink extrusion uses 28 tapered fins of 1mm to 0.5mm in thickness. The fins are all spaced roughly 1.5mm apart and are no more than 29mm in height. The baseplate is the standard 6mm thick which most aluminum heatsinks adhere to. The shroud keeps the fan 4mm above most of the fin tips.

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.
