The only way that would be a valid analogy is if the case was sealed
and did not exhaust the hot air. In reality a fan moves a lot more
heat than it generates. They use low vontage fans to make listing a
lot easier. U/L (and other NRTLs) scrutinizes line voltage a lot
closer than it does low voltage from current limited supplies. You
would also have the problem of PCs being sold around the globe with
all the different voltages available. A PC supply has a fairly "wide
mouth" running on virtually anything from 100 volts to 250 volts, 50
or 60hz.


That's true. I studied it for a while because this laptop (HP Pavillion)
has always run "hot" although it has three fans in it. I am sure the
insides are good and dusty after 3+ years of almost constantly being "on".
Maybe I'll try one.
