When it comes to aircooling there are a variety of different ways to
go. The current aftermarket trend is to use an elaborate maze of
heatpipe to quickly draw heat away while OEM solutions tend to be solid
blocks of finned metal. Both do a decent job however heatpipes tend to
work a little more efficiently The one downside to heatpipes is that
for them to work well one side of the pipe has to be cooler than the
other and for this we turn to the tried and true method of active
cooling, i.e. the fan. @ Ninjalane
