Laptop coolings solutions have less marginal for safety in 100% CPU
utilization operation, but if the thing is in working order, it should not
cause any problems (cleaning of the heatsink with a vacuum cleaner or a can
of compressed air might be needed). If you are worried about the increase
in the surface temperature, you could place the laptop, with the lid open,
centered on a metal surface covering just 1/3 of the width (like the top of
a tower desk machine chassis). The cooling fan and the CPU socket is
usually to the side of the laptop, so this arrangement ensures minimum
cooling air inflow resistance and also makes sure hot parts don't damage
the surface below (unless the top of your tower is made from soft plastic...).

IIRC the temperature monitoring and pausing works only in Apple G3 and G4
laptops. If you worry about the noise of the fan, you could use a task
scheduler to run "dnetc.com -pause" and "dnetc.com -unpause" in a few
