Presentation
The Freezer 7 is one of the rare, cheap, heatpipes (less than US$40). The heatpipes’ specificity is that the evaporation area is halfway between the beginning and the end of the tube and not at the end. So, this system is closer to a four-heatpipe configuration. The copper base looks relatively raw, as do the finishing touches. It is made up of two parts to capture the two tubes. Blades are in aluminium, and they are present all the way to the top of the cooler.
The original (70 mm) ventilation is suspended by some sort of trapeze. The lack of skirt is quite surprising from the point of view of airflow optimization and guidance. Finally, the chosen fixing system is based on Intel’s clips system for box models. That means this one is only compatible with the Socket 775.
Installation
The installation is no more difficult than the radiator Box. Be careful with the cables as the fan blades don’t have any protection.
If it is used in a tower, one can orient the airflow generated either to the power supply or to the outside.
Measures and results
The table below presents some of the measures for 7 and 12 V. The ventilation, even it is low, is still acceptable for 9 and 12V. At 5V, the fan doesn’t start without external help so we did not carry out any measurements with this voltage. Finally, we measured results at 7V except for the full load phase in o/c, which wasn’t at all stable because of an overly high temperature:
Appraisal
The worst of all in terms of performances! Despite average performances in 12V and a moderate noise level, it is incapable of dealing with the load imposed by the Pentium 4 in full load if the voltage is reduced. In Overclocking, we were unable to obtain a result because the system crashes too fast. It is also the only one that makes the system completely unstable.
Performances went down rapidly when the voltage was slightly reduced. Temperatures reached were very high and the rotation speed was dramatically reduced. The low diameter fan and the lack of skirt don’t help at all and they don’t force the air through the blades. This design must be left out, even if it is silent under 9V…
