I've just recently acquired a NEC ND-3500AG to replace my failing 1300A. Now, I burn a lot of discs (typical geek stuff, if you must know) and I've been pondering if there was a decent method to keep the burner cool whilst it worked. I was thinking of sticking it in an extenal enclosure with a fan, but the increase in CPU load wouldn't be particularly desirable. Anyone have any ideas?
