We started philosophizing about different ways to cool things. Computer processors, motorbike motors, lots of other things are cooled by having a fan blow over cold metal.
We thought that if we could think of a construction whereby the intake has to pass over a fair sized amount of metal, it should cool it.

Then I went home. Sat there thinking that glass should be just as bad a conductor of heat as metal, so I fitted an old stormlight cooltube that I had lying around to the intake, shut the door, left it alone for 20 mins, then checked again. The temps dropped 3c.

I was really surprised at the difference it made. This idea could be developed further, I'm sure.

Thoughts?
