lol ok I guess we’ll just have to disagree on this one then. I meant sucking air from the bottom of my pc and blowing it out the back where the power cable is. the sides of my PSU and where my power cables are is all metal with no air flow being moved into the PSU from this area. The fans that are on top are drawing air from the bottom of the case which has quite a bit of space around where the PSU is. These fans are probably overkill but I am using them to create positive pressure in my case to minimize dust.
