So your conclusion is that the BIOS software controls the fan speed, but for
some reason SUSE manages to disable this fan speed control function of the
BIOS? Or that Windows has its own fan speed control software?

There should be an option in the BIOS to control the CPU fan speed based on
temperature, it can be disguised under a number of weird names (I think mine
is "AI Fan Control" or something stupid like that).
As for the GPU fan (which is far louder on my machine than the CPU fan), it
seems this is built into the OS/driver. Actually I don't remember XP ever
reducing the speed, so maybe it's something new for Vista?

So are mine when the GPU fan is on!
