Normal
That's actually the model I ended up going with. I got it for $40 on reddit! Would drilling holes in the top of the PSU case and adding and 80 mm fan be the best way to cool the power supply more? I have a 4.5 case and it's getting a little warm making my GPU fan go crazy due to the heat. It feels like most of the heat is coming from the power supply when I text the case.
