The Jonsbo U1 Plus is a nice aluminum silver cabinet with a glazed sidewall, but with only one rear opening for the 80mm fan. Therefore, I proceeded to edit. In front was drilled a hole for 120 mm. Fan-SCYTHE SY1212SL12L Slip Stream 12cm SLIM (1200rpm). Drill holes drilled at the rear for mounting two fans - ARCTIC F8 PWM Rev.2 80mm case fan with PWM control. Next I tried the cooler cpu Noctua NH-L9i and Cryorig C1. I decided for Cryorig C1, but the original fan 140x140 mm is quite noisy, so I decided to replace it with a fan- Noctua NF-P14s redux-1500 PWM-Cpu fan, but beware, spacing holes do not match the fan 140x140 mm., But 120x120 mm. I used the PHANTEKS Halos Lux 140mm RGB-LED to illuminate the fan - Alu Black.
