Anyone build one of these? Homemade fan temp controller?

I want to build this for a non-pc related project but I need it to do temps around 45-60 F for lagering beer.

I figure someone here has likely built it or something similiar. Anyone know what temp ranges this will work with?

Thanks

Well, first off... You'd need a sort of refridgerant system for keeping your temperatures under ambient.

I mean, you can't cool anything with a fan, unless the air you're pushing is cooler than ambient.

So, in my opinion... You'd want to make a very compact chiller (use an old air conditioning unit rated under 4000BTU/hr) and have it switch on if the inside compartment temperature climbs above 60f or so.

Yes, I am aware of the chilling aspect, it will be pulling cool air from the kegerator. The fan and "door" would operate when the temps got too high and off when the cool air from the kegerator cooled the lagering cooler to the right temp.
