Arctic Cooling Freezer64

Arctic Cooling Freezer64:
Supplied by: Arctic Cooling

Arctic Cooling has become famous with their excellent VGA coolers, while they also had a wide variety of CPU coolers in the product gamma, these heatsinks did not score very well in the performance area, although they were very quiet. The Freezer64 is Arctic Cooling solutions for those people looking for better performance and at a price of ~$35 it’s not too expensive either. Let’s see how it does.

    Construction :

    If you though the fan on the TTIC looked odd, well take a look at what Arctic Cooling came up with; a custom designed fan which does away with the housing and only keeps the fan blades and the motor, of course. The Freezer64 is a combination of copper and aluminum, 2 copper heat pipes pass through the base and dissipate heat through a series of aluminum fins. The base is fairly smooth, but small traces machine lapping are noticeable.

    Installation :

    Although the Freezer64 comes with its own back plate, it works perfectly well with the default A64 one also, installation is very simple, clip it on, flip a switch, done.

    In the documentation Arctic Cooling provided with the Freezer64 they mentioned that the heatsinks performs best when it sits vertical, so we’ve included results with the heatsinks orientated like that.

    Performance and Noise :

    The Freezer64’s performance is very impressive, the fan is very silent, even at full speed, and as you can see in the graph below, placing the heatsink vertically improves performance even further; especially at lower fan speeds the difference is very noticeable.
