With this function, the fan indeed runs at maximum speed, but for some seconds. The laptop does has a tool that provides a function called “Dust Removal”. The problem with the laptop is that the BIOS doesn’t allows setting up the fan speed and neither does it provide a “Turbo” mode, something that some gaming laptops have to allow the fan to spin at the maximum speed and prevent overheating.

This laptop fan is a 4-pin fan but the connector is propietary, meaning that the cables aren’t in order. It is a 2013 model (and we are in 2018 now. The laptop we will be seeing today is the Lenovo Y510p. The 3rd cable again is the cable that sends rotational RPM information to the PC, while the 4th cable is the one where the PC sends the signal to the fan to change their speed.

This is very dependent on the machine.Ĥ-pin fans are PWM-controlled. The 3rd cable sends rotational speed information to the computer and depending on the heat and the BIOS, it will either increase or decrease the fan to a specified RPM. 3-pin fans are Voltage-controlled, where the variance in voltage changes the CPU fan speed. In this post, today I’ll share you this method that will surely end with your laptop overheating issues.Īs you may know, CPU fans comes normally with 3 or 4 pins.
