  1. 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.
  2. Cooler Master V750 Semi-Modular noise

    Hi, I have "Cooler Master V750 - Compact 750W 80 PLUS Gold Semi-Modular PSU". When I connect it to power cord I am getting a buzzing noise similar to this. When I switch-off the on PSU power button I still get the same noise. I am already using a surge protector and my electricity connection is grounded. I am not using any PCI GPU. Is this coil whine? I have just purchased a new GPU which will be arriving in ~November. I don't want to damage it. What should I do now? Product was bought from amazon and it's about a year old.
