Well, alas, there's really nothing to be worked out. It's a pretty good computer, which was given to me free. I'm going to keep using it until it dies or it gets too slow, so that means I simply get no temperature sensors and have to hope I'm not melting it.

But it HAS ensured next time I go looking for a gaming computer, Dell won't be on the list of sources. Probably just build the damn thing myself.
