Of the eleven heatsinks we used for comparison, the Blizzard S370 managed to rank in a number 4 position. The results of the S370's performance came in roughly 6 degrees ahead of the lower-profile S370-L. A difference easily understood by the differing sizes of the two Blizzard heatsinks, and by the much more powerful SanyoDenki fan on the S370. Comparatively the CAK38 ranked in the number one position - though the CAK 38 is a much rougher looking heatsink.

The new Vantec FCE-6030D came in a couple degrees behind that of the S370 on both the large and small copper die template tests. While the S370 is intended for Socket A processors we still find testing each heatsink on both the large and small copper die template to be invaluable. Generally, the results with the large copper die template should be lower than those of the small copper die template. In instances where this is not true, it can indicate a heatsink may have difficulties with larger heat loads.

Once more we can see just how well copper does when stacked against aluminum based coolers. The Blizzard S370 manages a number four position against our set of reference heatsinks, and a very impressive large copper die template temperature value.

Conclusions:

While the Blizzard S370 has not managed to wrangle in the number one position from our group of eleven reference heatsinks, it has managed to place in the top four. The temperature rating coming in only three degrees less than the popular Globalwin CAK 38.

The Blizzard offers thicker fins than the CAK38, and a much better base finish but cannot match its' level of cooling performance, even if just by a few degrees. At a cost of $58USD the S370 does offer some what you would expect from a copper heatsink of its' size. The Sanyo Denki fan is a great cooling solution, though it lacks the RPM output craved by many motherboards these days.

The clip used to attach the heatsink to the socket is easy to engage, and not so stiff that you wonder if you're putting your processor in danger. Definitely worth considering if you are in the market for a solid copper heatsink.
