Okay, Silly Question time. I'm now the proud owner of a Cooler Master Silent Pro 1500W M2. I'll be putting in a Cooler Master HAF X case, and in THOSE cases, the PSU is mounted on the bottom of the case. My question is, do you mount M2 in the case with the PSU Fan facing up or the fan facing down, or does it REALLY matter? Thanks in advance!
