AVC 112BJO Heatsink Review
AVC 112BJO Heatsink Review
Abstract: In the days of copper-this and copper-that it is refreshing to see a good old all-aluminum heatsink crop up to tackle a 1.4GHz Athlon.

AVC 112BJO Heatsink Perspectives

The Fan:
The fan is 60mm wide and only 11m thick - very slim. Listed as a ball bearing cooler, the 11-bladed fan pushes air into the fins at a respectable 4800RPM. The fan connects to the motherboard via a three-pin connector, and has a lead for RPM monitoring. A fan shroud helps move air over the full 78mm length of the heatsink.

Heatsink Top:
Contrary to some heatsink designs, there are no cross-cuts other than the 6mm gap for the chip to sit in. Each fin section is 35mm in length, and there are a total of 28 fins in the heatsink.

Side A:
Each of the 28 fins is roughly 0.5mm thick and 23mm tall. The fins are spaced 2mm apart. The base measures 5mm thick and is undercut to make room for the socket cam arm. The fan is attached by simply squeezing the screws in between the outermost fins.

Side B:
The only cut mark in this heatsink is the 6mm path which forms the clip trough. The finish on all the fins is quite smooth, and no serrated marks are evident to increase turbulence. The clip requires a screwdriver to engage - which can be a bit of a pain at times.

Heatsink Base:
The base has a fairly standard non-machined finish to it. A pink thermal interface material is shipped on the mounting surface. For our tests we removed this thermal substance however. The base shows some very slight marks from the extrusion die, and is bowed outwards a small amount. Machining of the base would have been nice to see.
