![]() This is because 4 pin fans change their RPM and voltage as per the needed for maintaining good temperature of CPU. The life expectancy of 4 pin fans is more than 3 pin fans. While 4 pin fan connectors are designed for modern CPUs with higher power consumption. The conventional 3 pin connectors are designed for small fans with low power consumption. ![]() ProductivityĬPU fans are always placed on a copper or aluminum heatsink use either a 3 pin fan or a 4 pin fan connector. While 3 pin fans rotate entirely at high potential by which you will experience much more noise than 4 pin fans. In this way, the fan changes RPM based on the need for temperature and eliminates the loud fan noise to a greater extent. NoiseĪs you know that PWM regulates the fan RPM. That’s why PWM presents on the modern motherboard, and other video cards, etc. This might not be suitable for modern PC needs. That is, the less voltage we apply the slower will rotate. You can also control the rotation speed in the case of 3 pin fan connectors but the thing is that they are up to some extent and not as automatic and accurate as much as 4 pin fans. Similarly, as the processor shifts to light work, the voltage and RPM of the fan slow down automatically. For example, if the processor is busy with heavy work on the computer the 4 pin fan increases the voltage in order to control the temperature. PWM fans i.e 4 pin fans simultaneously control the voltage of the fan. ![]() There are four differences between 3-Pin and 4-Pin Fan connectors. Now let’s see the difference between 3 pin and 4 pin fans. I hope you got clear of 3 and 4 pin fan connectors. In other words, the longer the voltage is applied to the fan motor coils, the higher the rotational speed and vice versa. It adjusts the RPM using a PWM signal and simultaneously provides tachometer feedback. The PWM wire is very important for proper CPU cooling in modern PC towers. ![]()
