Provided with all new Intel CPU, the Box is one of the most common radiators. The one provided with the Pentium4 540 is a standard model with copper base and aluminium blades. An 80-mm fan powered by the new 4 pin connectors ensures the ventilation. The installation system is the same as most of the thermal dispersal’ because it is, of course, Intel’s official solution.
Installation
There are no particular difficulties for the installation. It is done in a few seconds.
Measures and results
The box fans reacts strangely to Voltage modifications. Below 7V, the rotation speed re-increases to reach 1740 RPM at 5 V. 5 and 6V voltages therefore do not offer any particular interest.
Appraisal
The Box is far from being the best cooler in terms of thermal efficiency, but Intel made some serious progresses for the fan choice. This one is quite silent compared to previous generations. At 7V it even has an excellent noise level, but thermal performances are much lower, and so it is unfortunately practically last. We can’t really complain anyway about it because it is given for free with each processor…
