The Fans:
For some reason which is really beyond me, Globalwin make a point of replacing the traditional manufacturers sticker with a plain black circle. I'd hazard a guess and say that the fan here is made by either Delta or YS-Tech and I doubt that is too far from the truth. The fan supports RPM monitoring and connects via a standard 3-pin motherboard fan header.

Bare Heatsink:

The heatsink frame is set up for 70mm fans only, so you can upgrade the 15mm thick version to something a little more beefy if you want. Moving to an 80mm fan would require a little more effort, and at least one fan adaptor. Again take note of those nicely spaced nickel plated aluminum fins and that mysterious space down the middle.... h'mm maybe it is some kine of "crop circle" but in the shape of a line, and in the fins of a heatsink!! Ohh scary stuff kids :)

Side B:
The fins are all 40mm tall, 0.5mm thick and spaced 1mm apart. The two horizontal lines you can see in the background of the fins are special punch outs that keep everything properly spaced. The copper base is a scant 3mm thick.
