Review on 🌈 Cooler Master MASTERFAN ARGB/PWM Hub - 6-Port Addressable RGB Lighting with PWM (1-to-6 ARGB PWM Hub) by Christopher Shah

Based on other reviews I only half expected the PWM functionality to work. Unfortunately, all three of my 120mm Noctua fans are running at 100% regardless of the PWM setting in the BIOS. The documentation says absolutely nothing about what to do if this feature doesn't work, other than making sure a PWM fan is connected to the RED connector. I need to dock the stars for this undocumented limitation. I could try switching the fan ports and see if that has an effect, but I'm currently hesitant to open the computer again.
