no you only need the freq. generator (NE555) and a thermoresistor
then put a normal pc fan on the ground and the freq. out
just play a little bit with the freq., duty cycle and diffrent caps

I want to see the actual circuit...

from whre can i get this pwm???
-
What microcontroller are you using?
Is there anyway you can share the code?
-
He's right!
First God damn Google it before asking questions of those you can find the answer on

nice. what/where can i get something for my shuttle 200w fan. it's quiet but moves air with such force it makes noise when hits metal fan guard. DX has a cheap 7-12v rated 3-pin resistor. i'm not sure if i can connect to +5v red wire psu fan.

u dont know?
lets google it out ;-)
Type in search bar on wikipedia-site "PWM" - pulse with modulation.

This not use a µc.
Totaly analog circuit, using Operational Amplifiers.
