AVC Tundra 2 All Angles

The Fan: A plastic translucent fan grill protects the fan intake from loose wires, and blends in so that it is almost invisible. The fan here uses hydraulic bearings which are supposed to increase the useful life of the cooler, which is listed at 35,000 MTBF. The fan connects via a 3-pin fan header on the motherboard and is held in place by four machine screws.

Top: If you're thinking about dropping in a newer, or larger 70mm fan, the first thing will be to find screws with the relatively tight pitch used here (M3-P0.5). The two stainless steel posts are held in place by small copper rivets at the base. The clip is really stiff. Even though it has a small thumb tab we had to use a pair of pliers just to help engage it.

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 26x28mm 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 tool free, but very, very stiff.
Side B:
The first thing that we noticed when looking at the Tundra 2 is just how thick the base is. At just under 6mm, it is an improvement on the original. The area where the clip fits in is 4mm thick, and the relatively flexible sides where the stainless steel fan mounts attach are 2mm thick. Each fin is 0.3mm thick and spaced just over 1.0mm apart.

Heatsink Base:

The base of the AVC Tundra 2 has been sanded to give it a slightly textured surface (it is fairly smooth, but looks rough). Flatness is good, but not perfect, as the sides of the heatsink rise up a little. Overall, the base where the processor comes in contact is pretty flat though.
