3. Power supply ventilation
The following information is optional, and subject to the existing ventilation of your particular chassis. Please disregard, if your computer
chassis already features a blowhole, with or without fan.
The S320-12 power supply features a built-in temperature controlled fan, which activates as needed. Since the power supply is being installed
in a confined area, and in order to reduce a heat build-up inside the chassis, it is essential to optimize exhaust of the hot air that the power-
supply generates. A blowhole will accomplish just this, and should be located as close to, or preferably directly above the power supply fan
exhaust vent. Ideally, a low CFM 80mm fan could also be added, if space permits. Such solution will typically greatly reduce the activity of the
power supply built-in cooling fan, resulting in lower operating temperature both inside the power supply and the computer. If such a fan is
installed, it should be extracting air from the case (blowing towards the outside).
The template below provides holes dimensions for such 80mm fan blowhole. A fan guard and snap rivets are provided with the kit to complete
the installation.
