Successful! System is being restored to the new Seagate MomentusXT, 500GB, hybrid drive as I have a celebratory beer - appropriately, a Sierra Nevada Celebration Ale.
Hmm, that 7200 RPM HD shouldn't be generating that much more heat to rev the fan full blast. Are you sure the HD sensor and cable is solid?
Unless the SSD integration is causing it, but those are supposed to run cooler. If the computer is sleeping and you wake it do the fans come on soon after waking? The HD should take quite a while to build up enough heat to rev the fans is what I'm getting at.

(ambient room temp is 73ºF at the moment, and FF and Mail are the only apps running. It takes a few minutes before the fan ramps up after waking.)
The fan ramps up when the CPU is being used/maxed and heats up. Maybe I made better cable reconnects when I reassembled the Mini yesterday. Internal sound is working again, too.

From my travels I've found that an open/bad connection on a temp sensor will cause the machine to think that the temp has risen though. It's a failsafe mechanism that I've seen on all kinds of equipment in case of a bad sensor or open connection so that your unit doesn't overheat.
If it was a bad thermal sensor connection it would cause the fans to ramp up right away.
BTW I mentioned resetting the SMC as fan speed control is one of its functions.

The most noticeable improvement is with virtual memory. With only 2 gig-o-ram in this little Mini, VM reads and writes were becoming quite noticeable with the "old" drive. Since installing the hybrid drive, there is no noticeable system sluggishness when the physical RAM is fully occupied.
