Blizzard S370 Perspectives

The Fan:
The Blizzard uses a 60mm, 7-bladed Sanyo Denki fan like the MC462A Rev1. This fan though is only 25mm in height. Fan is powered from a Molex connector so it draws its' power directly from the power supply. The Molex connector is not a pass-thru type however.

Heatsink Top:
It's always mesmerizing looking down onto a fresh set of copper pins, and the S370 is no different. The heatsink ships unassembled, so it is up to you to put it together before it will cool a single thing. All the fins are on a 2mm spacing regime, and each fin is ~29mm tall.

Note the four clips, one on each corner which help to hold the fan in place securely.

Side A:
From this angle it is easy to see how the fins are interconnected with the copper base. The Blizzard uses a wire-based clip to hold itself in place. The benefit of this approach is that no fins have to be cut down in order for the heatsink to be mountable. The clip is quite easy to engage, and places a moderate amount of force down onto the processor core. The entire heatsink sits 59mm tall.

Side B:
Looking at the other side you can see the basic component which has gone into making this heatsink. Each fin is identical to another and is stamped from a sheet of copper. The fins measure 62x31mm and have (10) fingers measuring 4x20mm.

The base of the Blizzard is notched out 2mm to make space for the socket cam arm.

Heatsink Base:
Though this photo of the base is a bit washed out, the base of the Blizzard is polished smooth. The base is not perfectly flat, but rather very s
lightly domed inward. The curve is so slight that is shouldn't pose any problems with a small silicon die mounting properly.

Time to test out the Blizzard S370 copper heatsink on the Frosty Synthetic Temperature Test platform and compare it with several other reference heatsinks.
