Thank you BradtheRad for your feedback, unfortunately i got away from this project because i (finally) found work :-)
1. I used 2 transistors because i did not thing the comperator could turn the larger transistor on by it self, but if i can it would simplify the circuit allot.
2. I did not...
Yea, i never got round to actually building it, im not motivated not knowing if it would work or not.. i don't have the equipment nor the skills to bug find it once build.

Well, i guess i will have to just build it and seem what happends, had hoped for a little feedback.
I have since found a possible error with the 100K POT, i think that needs to be made part of a voltage devider, instead of just a plain variable resistance.
So i will change that and make a muck...
Hello, i am made a temperature controlled fan circuit, but since im new to this im not sure if i made it as optimal as i could.
I prety much used the standard recommended applications from the datasheets, and mixed it up into a circuit.
The temp. censor i use is a LM35, and i used it like...
