That's akin to saying that a mainframe generates more heat than a PC. Sure,
it will, but the reason is not that it has a bigger power supply.

The point is ismply that if you have two otherwise identical running
computers that differ only in the size of their power supplies, the one with
the larger power supply will not generate any more heat.

Hi Sharon-It's a Pentium 4. HP told me last night that 51 degrees was
perfectly normal, but she didn't elicit any real confidence from me. Intel
responded but they want the cpu's spec #-I'm waiting for them to tell me
where it's located. On the cpu itself, I'm guessing. (slxxx, or something)
I would never have posted this question, & I'm referring to the wattage
vs heat issue, if had known it was going to create discord, Thanks-Alan

No problem, Alan. You have a new power supply and noticed a slight increase
in heat. I misinterpreted your concern about the heat. Sorry about that.
Probably due to my frame of reference: I run AMD chips which can fry in
seconds if temps are too high. Rare but this can happen even with temp
monitoring/auto-shutdown enabled in BIOS. P4s are not immune to heat
problems either but they are a little more resilient.
