Adam - my Al-book (1.25G, 1Gb RAM) also runs hot. 
I now use Temperature Monitor to measure it.

I am currently 63.2°C.  The main cooling fan is 
on a lot of the time.  The additional fan also 
comes in from time to time (just gone off now, as 
the Temperature is down to 60.5°C).

Actually, the regular cooling fan is relatively 
quiet (compared to the original Ti-500 that I 
had, that sounded like an airplane revving up).

It is unfortunate that the FAN is close to the 
internal microphone.  So if I am recording a 
meeting, or using internet telephony, the 
internal microphone picks up the fan in a biig 
way.

It means that recordings of meetings are poor, 
because every few minutes the recording is 
swamped by the sound of the fan, and it also 
means that I can only use internet telephony when 
the Al-book is very cool, otherwise my voice is 
not heard above the whirr of the fan.

I would say that these are design issues.  I am 
not sure where to feed this back to at Appple.

I know that an external microphone would solve 
these issues,. but that is a workaround, not a 
solution.
