Igloo 3300 From All
||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
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
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.
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
