Masterfan 120 rgb issues

Recommended Posts

I really thought these were going to be the best fans on the market. Theyre a combination of a good coolermaster fan reminiscent of the xtraflo fan from the 212 evo, and RGB LEDS which can never go wrong. The big issue is noise. These things sound like a lawnmower. The noise gets worse at higher rpms and much better at lower rpms so its not bearing noise, its a form of coil whine. Theres also control issues such as the fan not even going to 0 rpms on pwm, and if you use voltage, the leds turn off as you lower the voltage. The PCB is too bloated. The design has 4 super bright leds, a pwm mosfet, probably some led mosfets, 4 giant radial coils, an overcomplicated driver and finally, the leds are powered off of the fan header instead of the simpler solution  of just using RGB power.
