Just tried two sets of fans and got system fan errors. PWM Fans Arctic Cooling. 140mm fans are generally quieter and move more air, making them a great choice for any case that can handle the larger size. But Cooler Master's exclusive Silent Driver IC slows down the signal rate, suppressing the PWM switching sound. IIRC, the originals were also 38mm deep, but virtually all replacement fans will be less than that since they don’t have has large a motor, and smaller is OK in this case. SilentWings® 3 fans stand for state-of-the-art technology, virtually inaudible operation and superior cooling. These fans can move an amazing amount of air through restricted environments compared to other fans at the same, minimal noise level. Noctua competes with other top brands whose fans are much more powerful, and yet it still delivers.

More efficiency means less heat wasted, and that means quieter fans. Pulse Width Modulation (PWM) is a nifty current control technique that enables you to control the speed of motors, heat output of heaters, and much more in an energy-efficient (and usually quieter) manner. That and the booster fan on the heatsink are the loudest. In my opinion, I would say all CPU Cooler fans are PWM-controlled. Hi, I have a VIII Hero. It has a broad range of application, like in the field of telecommunications, audio equipment, servo motors, etc. Supporting fully automatic PWM speed control, the fan uses Noctua’s custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. - Fantastic build quality (as expected). We will be looking at them as case fans. I bought the two we will be testing for a heatsink, since these are PWM fans. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds. The P12 is optimized for static pressure. Best Static Pressure Fans 120mm Reviews 1. Stops at 0% PWM. Some CPU Fans can be quite loud and annoying when running at 100% but when using PWM the fan is running quieter unless the CPU gets very hot thus cutting down on noise and electricity. Achat vérifié.
