Figure 1
Figure 1 above illustrates a typical CPU cooling installation. Notice the use of Coolsleeves in very tight bends to prevent the tubes from kinking.
Also note the position of the auxiliary power supply in the uppermost drive bay. Since this unit generates a significant amount of heat, a case
with a blowhole on the top panel is desirable to reduce the overall internal case temperature. Candidate case-modders may take this one step
further by adding a blowhole with a very slow (quiet) 80mm fan directly above the power supply vent. This will provide constant cooling to the
power supply, and prevent its’ 60mm fan overheating protection to quick in. The benefit is reduced noise, and prolonged life for the PSU.
We installed a blowhole in this chassis to provide adequate ventilation to the auxiliary power-supply.
