I tested my player on my desk for a whole day with a MDF dock with NO vent holes drilled in it, and the temprature never got above 100F. In my car, the Empeg averages around 110F-115F. Maybe this is because it's my basement, and it's usually really cool down there (I wear a sweatshirt usually) but I don't think temperature is going to be a problem. I would say it might be because it's driving two drives, but I have two drives also, a 40g and the stock 10g.
