cooling fan problem?

may be dumb but here goes...

is the cooling fan on my computer supposed to run all the time when the computer is on? it used to kick on and off but now stays on the entire time the pc is on. is there somewhere you can adjust this setting...maybe it was changed accidentally or something?

The fans in any PCs I've dealt with stay on all of the time. I guess it's possible that some newer ones may have some sort of thermostatic control to turn the fan on and off but I've never seen them. Maybe someone else will have something to add but in the meantime, the fan running constantly is not a problem.

BTW, if I were you I'd just call Dell and ask if it's normal. You should have a free 24/7 800 tech support number if I'm not mistaken.
