Coolink H2T From All Angles

The classic "H" design of this heatsink seeks to double the surface area in direct impact with the airflow in a minimum of space. Each of the two fans are held in place with two small spring clips. The central portion of the heatsink measures 6.25mm thick. The fins are roughly 25mm long, 1mm thick and spaced 1.70mm apart.

Top: The copper base of the heatsink is 4mm thick and dip brazed to all of the bottom side fin edges. The three large cross cuts are only superficial, and are just there to allow the clip to lock into place. The main clip is locked into place within the heatsink and the holes cut for it also serve as exhaust vents.

Heatsink Base:

The base has two really large indents from a stamping procedure which is used to ensure proper alignment on the fin assembly. The copper base is dip brazed to the nickel plated aluminum and so the thermal joint should be pretty consistent all the way across. The base is perfectly flat in one axis, and slightly curved in the direction that the sanding went. The base itself measures 48mm x 57mm.
