I have recently installed a Denon 3801 and finally have it running smoothly. But it runs *very* hot, particularly now that I have it running the TV audio signal which means it gets heavy use. You can almost burn your hand on it. It is bad enough that after running continuously for about 4 hours, it started going into something like protect mode, where the power light flashes. This could be a short in the speaker connections, but given how hot the unit was, I am guessing it was heat (the manual says it can be either of those 2 things). Is there somewhere I can buy a small fan that will clip on to almost any service and uses a conventional plug? I am looking for something that will fit in the back of my TV cabinet where the Denon resides. It must be pretty small, as there isn't much space there. Any other cooling suggestions would be helpful.
