I have a small apartment and a large freezer; I'm concerned about heat build up in and around the freezer.
I have a similar problem with an old PC tower, to which my solution was to create and external radiator from empty coke cans and fix it to the exterior of the computer case. It's worked very well and the always-on PC is as cool as can be.
My question is, besides warranty issues, is there any reason I couldn't/shouldn't make another external radiator, and use crocodile clips to fix it to the grounding and the internal heat dissipator?
