u/Accomplished-Toe-811

Air cooled PC.

Gonna run either 3 x 120 fans (right most fan as intake) or 2 x 140 mm fans (Still with right most fan as intake) at the top. But I am unsure what would be best?

120 will look better but have more noise.

140 will look worse as there will be a gap between the two fans.

in terms of noise, I guess 140? 120 for performance? But how much does this differ.

Fans used will obviously be Noctua. Leaning 140s as I can get the Chromax G2..

Please help me decide.
