Default temp cantroled fan circuit

i know this is not an amp, but it uses a chip, and will be used in a chip amp.

will any/all of the following 3 circuits work? will my circuit (attached) also work? do i need to add anything, can i remove anything? do i need feedback? one of the 10k resistors in the right hand potential divider will be a verial resitor to set temp. also, the values are not correct, i will have to play around. thank you for any help in advance.
