Ok if i put my motherboard in mineral oil and in a cat litter box and if i stuck cat litter box in the mini frigde/feezer, and put fans to stir the oil alot .. would that supply good cooling?

Actually the question might be more to:
If I stuck three 100watt lightbulbs always on in a freezer and left it there all day. And opened the freezer.. Would it feel warm or cold?
