Fermentation Chiller circuit

Hey everything else is done, I just have to wire this baby up then i am going to post some pics of the finished unit. I got a digital thermostat that I will extend the leads coming off the board for the thermistor, so I can mount the thermostat outside of the chiller. I am taking a huge shot in the dark with the fan circuit though, as I have never used a thermostat before. does this circuit look like it will burn my house down?



if that didnt work try this one:

Im gunna bet this is way wrong...
Thanks a lot for reviewing my circuit, any input will be greatly appreciated.

im thinking maybe connect that one wire to the G terminal instead of Y? ((bump))
