Not bad I installed 2 120mm long distance radiators, had to use a washer so I could mount them on a grille (with 120x15mm fans air out on the case) and the remaining fans are inserted. I haven't tried it on this non-liquid-cooled PC, so temperatures may vary depending on your preferences, with a bit of space needed to install fans without shims. Low profile fans are a must. The size is bigger than the PSU, I had to move it down a notch. I use Ryzen 5 5600x OC up to 4.5GHz.
