t43/FC5: when does T43 start suspending?

Hi, there, I installed fc5 on thinkpad t43. no problems really.
However, when I close the laptop, the fan is still running. Why is that? Is this normal behavior? (That would really really suck).
I do happen to be running yum at the time to do updates, so that may be why the fan stays on.
In the power management options in FC5, I see that I can change certain behavior: put display to sleep and put computer to sleep. Also I have an option about whether closing the laptop will cause suspension or simply for the screen to go blank. That reassures me, and I'll try that out tonight.
If I suspend, will it still be able to run chron jobs? run yum? bittorrent?
If the computer goes to sleep, what happens?
Will the fan stop running when the laptop has actually gone to sleep?

In suspend/sleep mode the CPU is not working. No programs run, only the ram remains powered to preserve the system status. Fans will be off.
Try System -> Suspend to see the effect.

It's the same like in Windows.. you put your system to sleep it's as good as turned off.

Also note that there is a RediSafe feature that is supported, in both Windows, BSD, and Linux, in the BIOS that will automatically backup the RAM suspend state with a hibernate that occurs at the same time; so, if the RAM is deprived of power for awhile, you can still recover and resume your work from where you left off.
In addition, I believe swsusp goes to the S5 state and not the S4 state which, as far as the BIOS is concerned, is the same as simply powering down the system without hibernating first. As such, you can save your linux session, then go into Windows or what have you, then boot back into your linux session after you are done. Just make sure you don't touch the swap partition the hibernate image was stored to in the first place.
