Here is my problem. My friend's PSU(Q-tek btw
) recently died. I bought him a 300W beQuiet PSU that from what l know is a good brand. The only way for the PSU's 120mm not be covered would be for me to flip the PSU upside down. That positions the 120mm above the 80mm exaust fan of the case.
Is positioning the PSU in such a way considered acceptable?
