Dynatron A22 V-Shaped Skived Athlon64 Heatsink Review
Overall Rating:   75%
Abstract: The heatsink at first appears to be nothing more than a plain aluminum skived heatsink, but closer examination reveals a couple very effective innovations, not the least of which are the V-shaped fins.

Skived heatsinks are made with a heavy-duty machine that slices chips of metal from a solid bar of aluminum or copper so that they remain firmly attached at one end, left upright and straight. Skiving is a relatively new metal working technique, and it is very similar to the act of hand planning a block of wood except that 'shavings' are shorter and remain attached. The benefit of a skived heatsink has always been the lack of a thermal joint between the fins and base, since each is formed from the same raw material.

Dynatron has built up a reputation for itself by providing an array of skived heatsinks which continue to evolve fin and base geometries over successive product generations. FrostyTech tested out one of the companies latest socket 754/939/940 AMD Athlon64 heatsinks called the Dynatron A22. The heatsink at first appears to be nothing more than a plain aluminum skived heatsink, but closer examination reveals a couple very effective innovations, not the least of which are the V-shaped fins.

The Dynatron A22 employs V-shaped skived aluminum fins and an angled base geometry. The fins are not of equal depth from side to side, and the base basically has the shape of a large flat triangle to it.

A recess at the center of the Dynatron A22 heatsink provides space for the K8 clip system. The space between each set of 29mm wide aluminum fins forms a very broad V-shape as you can see above. The recess this creates just below the fan motor helps to reduce the build-up of hot spots. The triangular shape of the actual heatsink base facilitates good heat conduction, while gently directing exhaust airflow out and away from the body of the heatsink.

FrostyTech's Test Methodology is outlined in detail here if you care to know what equipment is used, and the parameters under which the tests are conducted. Now let's move forward and take a closer look at the Dynatron A22 V-shaped skived heatsink, its acoustic characteristics and thermal test results!
