Do the new MacPro fans stop in sleep mode?

The fans on my previous generation 8 core MacPro never stop, even when you try to put the system to sleep. So it basically never goes to sleep. Do the new MacPros actually go to sleep?

Thanks, Ed

MacPro, Mac OS X (10.6.5)

There sounds to have been a problem with your 2008's SMC.
It should and is normal for fans to shutdown during sleep.
And this on very first Aug 2006 PM1,1.

So the fans should definitely shutdown even with my old system? I thought they kept going all the time because even in sleep mode the CPUs and memory ran too hot. I don't have much Mac experience. What does SMC stand for?

Thanks, Ed
