OK, I've had a bit of a look, and there are no case fans at all at the moment. Which leads me to wonder why the guy that put together the system didn't try to upsell me on a fan or two...

So some fans are definitely in order. Or should I just bite the bullet and get one of Intel's "Thermally Advantaged Chassis"? I'd love to hear from anyone running the 540 processor in a standard case (likely with fans).

I've also checked the temps in the BIOS, as I read somewhere that ASUS Probe has been known to give inaccurate readings -- and found some strange results. Idling on the BIOS screen, my cpu temp was hovering between 65-67c! When I booted into WinXP, the temp started out at 60c and gradually cooled to the 46-48c I've been idling at in Windows.

So I booted into Windows with the side off my case, and was running a cool 36c idle. And then I booted into the BIOS again, and watched the temp start at 52c and climb up to 60.5c.

While in the BIOS, I noticed that the setting for the "cpu target temperature" was at 66c -- which seems odd, since the max is supposed to be 67c. I tried to determine what setting this should be at, but Intel's documentation makes no sense to me really, so I dropped it to 57c. I'm now running at 45c as I type this, and haven't gone back into the BIOS to check what happens in there.

So now I've got some new questions:

-anyone think setting the "cpu target temperature" in the BIOS at 57c is a bad idea? The only thing that I can think that it would effect would be the cpu fan speed, and it's pretty quiet right now. Should I set it as low as possible (which happens to be 51c)?

-any ideas why the BIOS would heat up the cpu so much?

-any reason I should not bother with fans & just go straight to the "cone-over-the-cpu" Intel-recommended case?

-as for fans: my power supply doesn't have an intake fan, and isn't using the connector on the mobo. Should I get 3 fans: 2 for the back (exhaust) and one for the front (intake)? Anyone else have other config ideas?
