AVC Z7H2403012 Internal Prism Base Heatsink Review
AVC Z7H2403012 Internal Prism Base Heatsink Review
Abstract: What is the newest trend in heatsink thermal design? Hint, it's not heat pipes, prolific amounts of copper, phase change materials or cold forging...

AVC Z7H2403012 Heatsink From All Angles
The Fan:
The AVC Z7H2403012 uses a thermally controlled fan to scale up its RPM from 2900-5400RPM depending on the temperature. The fan connects to the motherboard fan header with a 3-pin connector and supports RPM monitoring. No fan grill is included with the heatsink to protect the 70mm fan impeller from objects which might jam it up.

Heatsink Top:
The copper fins are spaced about 1.0mm apart, using the stacked fin process (I believe this is the name given to it) which is so common these days. Essentially, each copper fin is interlocked to the adjacent fins to form an evenly spaced assembly. The copper fins are very thin, measuring no more than approximately 0.2mm thick.

Side A:
From the side, it is easy to see the peak of the internal prism base. The photo was taken from the side of the heatsink, so if its base were flat, you would be able to see all the way through. Instead, we can see the copper prism rise about 13mm into the fins of the AVC Z7H2403012 heatsink. At the very edges, the base comes to about 1mm thickness.

Side B:
The 70mm fan sits on an aluminum fan shroud which has been anodized and coloured to look like copper. If you look closely at the bottom center, you can see the edge of the copper prism which forms the base of the AVC Z7H2403012 heatsink. Spring clips mount over top of the heatsink to hold it firmly in the socket 478 heatsink retention frame.

Heatsink Base:
There is 11mm of bare fin on either side of the copper prism which forms the base of the AVC Z7H2403012 heatsink. This space allows exhaust air from the fan to escape out and away from the body of the heatsink easily. AVC ship the Z7H2403012 with a pre-applied patch of white silicon thermal compound, which we removed before testing. The base is pretty flat (very slightly domed), and has a sanded finish to its surface.
