The rare CPU fan speed controller with aluminum- alloy panel has undergone multiple matt treatments and is suitable for any chassis. ^^ Equipped with a wide LCD screen, 4 sets of fan speeds, 4 sets of temperatures are displayed on the LCD screen, so you can see the computer work at a ^^ With a safety system with high temperature alarm and fan anti-seize. When the computer temperature exceeds 60 degrees, the temperature flashes and an alarm sounds. ^^ Use PWM circuit to adjust speed to reduce high frequency noise, and at the same time reduce noise by reducing fan power ^^ High-specification capacitors are to high temperatures, have a longer service life, and refuse damages such as electricity running and leakage
