That’s very overpressure, maybe too much so. I’d move the bottom rear fan to the top rear as exhaust.
But there's no additional fans on the bottom, just power supply
Or explain to me what do you mean, english is not my first language :/
Maybe this photo is misleading, there are 4 fans in total in this case, those fans market as "120/140mm fan"
Rest of the fans are from power supply, cpu cooler and gpu itself
Photo updated, how about now?
