In the case of motherboard PWM speed control, due to the motherboard current limit, adjust to 10% at a speed of 1050 rpm, and adjust the fan to increase the level of 405 per revolution at 10% to 100%, so it cannot reach 5500 RPM .
The maximum speed can be reached by directly connecting the power supply to a 12V positive and negative power supply.
Note: When the fan is undergoing a very, very violent test, please pay attention to safety. Don't let the blade cut your fingers. When turning 11 blades, the fan speed will cut the wind ruthlessly like an 11 cutting knife. Area, and cut mercilessly...time is up.
It is strongly recommended to use it with a safety net.
Start our exclusive support, you can use up to the current 5A speed controller with the fan
High-quality 12V DC current cooling fan speed, up to 5A
