3-pin vs. 4-pin cooling fan: Analysis of advantages and disadvantages of PWM speed regulation and voltage speed regulation
Mar 24 , 2025
Cooling fans play a crucial role in electronic equipment, servers, industrial equipment and other fields. For different use needs, there are two main types of 3-Pin (3-pin) and 4-Pin (4-pin) fans on the market, and their main difference is the speed regulation mode - 3-pin fan speed regulation by voltage, while 4-pin fan uses PWM (pulse width modulation) speed regulation. So, what are the advantag...

What is gridlock feedback technology?
Feb 17 , 2025
The cooling fan with gridlock feedback technology refers to a technology used to prevent the fan motor from gridlock (that is, the motor shaft is stuck or unable to rotate) during operation. It monitors the speed and current of the motor in real time to determine whether there is a lock-up, and when it detects a lock-up, it feeds back to the control system to start the protection mechanism or take...
