The system is not overclocked. (I don't think I could if I wanted to).
Compared with my desktop, the backend system is less crowded and
better ventilated, so I agree there must be something else causing the
increased temperature.

It's an HP Pavilion d4999t that I got used a couple of years ago. It
has an Intel Core 2 Quad processor, and I believe it has an Intel
ICH9R chipset.

I'll do that. Thanks.
