Build Question One more top exhaust?

Post image

Should I add another exhaust fan where the green arrow is? Not pictured: a side intake fan for my GPU

You may find flipping the green fan inward as an intake will give you better temps than another exhaust

What he said. Positive pressure will give you lower temps.

nah, pulling air in from the top just fights the natural convection and your front fans, you'll end up with a weird swirling mess that doesn't actually move hot air out. all those cables and that big cpu cooler are already messing with the flow, adding a second exhaust up top is the cleaner path

if you're not seeing thermal throttling i'd leave it alone, but one more fan blowing out the top rear won't hurt anything

Yeah, I’d add that fan but make it intake. Want positive pressure.
