It will produce heat none the less. It's just not allowed to build up by cooling effects. (air, or a heatsink) It's probably some faulty component that is below spec, and once you heat it up it loses efficiency.
Notice I said power supply, not transformer, there really should be no heat radiating from the supply. Dissipating 25W (SMPS are 85-90% efficient) shouldn't be a feat in engineering for Microsoft, Taiwans been producing fanless 400W PC supplies for a few years now.
lol...the PSU is the hottest component of a computer. The one's that are fanless are large, expensive and run hot as hell. I'm actually surprised that MS made the 360 PSU that small. I figured it would have been much bigger in which it should have been to preven these problems.
I'd guess if they did make it bigger and add a fan to it, then they wouldn't have this overheating problem, however, consumers would be turned off by the sheer size and potential noise it would create.
True. I personally think it should have been in the system. It should be interesting to see what Nintendo and Sony does with their PSU's.
Sony's might require some hefty power, whereas maybe Nintendo's will probably the most energy efficient of the three of them.
Considering how Nintendo doesn't do internal power supplies, I predict that we'll have another nice little Gamecube brick, which will draw a whopping 75W.
Indeed. Just found that out for myself yesterday...heard a little fan noise and felt cool air gently blowing out of it. I just keep mine perched on top of a book and it stays nice and cool...no ill effects with my system in over a week of heavy use.
