i found this, it's a IC that sends PWM into a fan to control it's speed according to temperture meassured by a termistor.

the problem is that it's for two fans and two termistors i only need one fan and one termistor.

Hi,

Read the datasheet and see how it works.

Hi,
Use one fan and one thermistor, leave the other thermistor input as a 1K5 resistor, don't worry about a fan.

Just a suggestion.
