Upboard fan control

I have the fan heatsink, i want to use the up-board for a NAS drive and since it has a fan I am worried about 24 7 operation and damaging the fan. Is there a way to controll the fan switching on and off based on cpu temps?

We use the GPIO pin to control the FAN VCC ON or OFF , , when boot up this pin is high level , when power down this pin is low level .

We can’t read the FAN RPM .
Current design is use a GPIO to simulate like PWM signal control the FAN VCC
