I knew there was a formula, I kept getting stuff about air conditioners and science projects when I searched.

Yeah, It reads a coolant temp. sensor and controls the radiator fan speed. This is...

Ok Thanks, I'll try some of those.
I like the to-220 package better. Do you think it will get hot mounted in a small project box with the rest of the circuit?

I intend to control an automotive radiator mounted fan using HPWM on a P16F690. I selected this transistor to drive the fan, but please look at it and tell me if this is a poor choice.

Thank you very much :)

Second is a question,
It may be my paranoia from the stamps but how does one keep up with the...
