As there is always some difference in the ambient temperatures during testing, it's interesting to see what changes in order the reference heatsinks take with the heatsink being tested. In this case I think things are going to stay pretty much the same.

The AVC 112C81 is essentially a retrofitted extrusion heatsink which has been upgraded with a copper core. The addition of that copper, and AMD approval should guarantee that we are not looking at an OEM performance level heatsink, but more of a good performer.

True to form, the AVC 112C81 is able to produce some very respectable performance levels; in fact, coming quite close to the levels that the AVC Tundra 2 was able to attain. The copper core in the 112C81 adds that extra amount of surface area for the aluminum extrusion to make contact with - that that means heat energy is spread out over a larger area so that more fins are being used for cooling. The alternative may have been just a hot-spot at the center of the extrusion, which obviously would have been directly under the motor of the fan and doing no one any good.

AVC have let us know that they are actively making the transition from supplying OEM coolers to supplying consumers with heatsinks that work well. While the AVC 112C81 is certainly fine for your average AMD AthlonXP running at stock speeds, I don't think it has the cooling capacity to satisfy any level of performance overclocker.

My only request for this heatsink would be for it to use all three clips on the socket instead of just one. There are too many stories out there of broken socket clips, and use of all three in this instance would be good for everyone. Otherwise, the AVC 112C81 is a heatsink.
