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.
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.
