Just dip your rig in non-conductive oil
So they make a 500mm fan? Where??
I'd only do 3 fans at max. Just like the setup ZZK suggested. Quiet and gets the job done. I think my computer now only has 2 though. Wait, it only has a back fan.. What's up with that?
Well Nooo I don't think anybody does make a 500mm fan for a computer I think I was being a bit exaggerative lol but I do know for a fact that 400 mm fans are made where to buy them I really don't have any clue as far as I know they're only made for computers that were designed to fit a 500mm fan
like this case for ex.
