PC Power & Cooling Silencer 750 Quad CF-Edition

The Fan



There is only a single fan installed in this PSU, which is somewhat surprising given the high power rating. The 80mm fan is located at the back of the housing and pulls air through the internals. The front of the unit has several long openings in it that serve as air intakes. The openings are located directly behind the components that need the most cooling, though, so the airflow is put to maximum effective use.



This is a very common arrangement as it provides for better control and direction of airflow. The fan side facing the rear is labeled with a PCP&C-sticker. Note the small decimal point in front of the 45A near the at symbol (@); for a moment we thought we had discovered the destination for most of the electricity. The other side of the fan makes the rating a bit more clear: it is an ADDA fan rated at 0.45A.



One thing we didn't mention before is the length of this power supply. At 18cm/7" in length it is a very long PSU. A look at the website of PCP&C explains the reason for the size. By keeping the fan at least one inch away from the PCB and its components, according to PCP&C this is the best way to avoid noisy air turbulence infront of the fan.
