A fan script for a beginner

[sdetweil]

@peter so, you made a transistor based relay… cool…

but that doesn’t help his speed control question…

[sdetweil]

@cyrus1337 the specs do not say how the yellow wire is used to control the fan.

Maybe you misunderstand me. I just want to turn on the fan and turn it off when the CPU has more than 50 °. I have 3 wires on my fan as shown above.

That is exactly what I told you before.
Read the article and you will see how to connect the 3 wires.
And you can change the temperature of the fan to start.
My fan starts at 65 and runs for 30 seconds to cool the cpu.
