AVC 112AM1 Copper Skive Heatsink Review

Abstract: The first thing that we noticed when looking at the 112AM1 is just how thin the base is. At just 3mm thick it is half what most other heatsinks are.

AVC 112AM1 Heatsink From All Angles
The Fan:
The hologram really does nothing for cooling, but looks nice in this shot. That the fan is translucent is merely marketing. The fan draws 0.19A and is very quiet in operation (it is not a high-RPM fan). For the size of the heatsink the fan is proportionate. It connects via a 3-pin fan header on the motherboard and is held in place by four machine screws.

Heatsink Top:
If you intend to drop in a newer, or larger 60mm fan, the first thing will be to find screws with the relatively tight pitch used here. The two posts are held in place by small copper rivets. The clip is really stiff. Even though it has a small thumb tab we had to use a pair of pliers just to engage it, it required so much force.

Side A:
The skived fins always have a very clean side, and bumpy side to them - this results from the process and is unavoidable. Each pair of fins is 21x18mm square, with a scant 3mm distance between the base of the fan and the tips of the fins. As we mentioned before, the clip is very, very stiff.
Side B:
The first thing that we noticed when looking at the 112AM1 is just how thin the base is. At just 3mm thick it is half what most other heatsinks are. The area where the clip fits in is just 2mm thick, and the relatively flexible sides where the stainless steel fan mounts attach are only 1-1.25mm thick. Each fin is 0.5mm thick and spaced just over 1.0mm apart.
Heatsink Base:
The white material is pre applied thermal goo, and it makes installation simple. The base has a hair line finish and is smoother than it looks. With a good quality thermal goo (or what comes with it) you probably shouldn't be concerned about lapping, the base is fairly smooth. Flatness isn't to great, but that is to be expected from such a think base plate. There is a little waviness visible when we tested with the engineers straight edge.
