Typically, the PC power supply is one of the main culprits for making fan noise, because usually its internal components generate so much heat that a fan is inevitably required in order to keep its temperature down. However, NoFan have taken a different approach with their new fanless power supply. It offers ample power and complete reliability and safety, even though it has no cooling fan whatsoever!
It is designed primarily for excellent efficiency, which in itself reduces heat output because more AC power is converted to DC power with less unwanted heat being generated in the process. In addition, the whole of the base of the power supply is one big heatsink, as can be seen from the fins on it. By using a heatsink with such a large surface area, heat can be dissipated passively and without the need for forced airflow.
Given that modern processors and SSD drives have ever-decreasing power requirements, the 400 watt continuous possible power output from this NoFan PSU will be ample for almost any general-purpose PC.
If a high-power 3D gaming card is installed, however, we would recommend that a conventional power supply be chosen because such graphics cards alone can easily consume 200-300 watts and sometimes more! However, for most people who are not 3D gaming enthusiasts, the NoFan P400-A represents an excellent investment for a silent-running, dust-free, reliable and long-lasting computer.
