| Details: Processor Cooling for Peace and Performance!
Rather than using clips, this unique cooler is mounted using screws through holes in the motherboard, and this means that it is amazingly versatile. Not only is it compatible with socket 423 Pentium 4 processors, it also works with Xeon socket 603 and AMD socket 462/socket A! It features an ultra-quiet 60mm fan and is effective up to 3 GHz. It comes presented in a box containing the heatsink/fan, Fan Mate speed controller, thermal compound, screws/bolts/washers, bag of spare parts and instructions.
Because of its excellent cooling performance, and relatively small form factor, this cooler is recommended for multiprocessor machines. With minimal CPU socket overhang, it is very unlikely that there will be any clearance problems in mounting two or more of these coolers adjacent to each other.
The speed of the fan is controlled using a Fan Mate variable voltage regulator, so you can set this manually to the speed you require, for best balance between noise and CPU temperature. At its lowest speed setting, adequate cooling is achieved even for the fastest processors, and the fan is almost completely inaudible.
It is recommended that you try to keep your CPU temperature below 70-75°C for reliable operation, but there will be no problem achieving this with the CNPS5100-CU cooler. In practice, temperatures as low as 35-50°C are often achto people who need a quiet computer, and also those who need minimum CPU temperature for best stability when overclocking (overclocking is done at your own risk).
IMPORTANT: To be able to successfully install this cooler, your motherboard needs to have four holes around the CPU socket as shown below. A S423 layout is pictured, but if the cooler is to be used with S603 Xeon or S462 AMD, similar holes must be present.
