OK, I will.  I got taught, in extremely clear fashion, about the direct linkage
between keeping the temperatures low and even, and the ultimate reliability of
your system.  I won't go into the war story, but most everyone knows this is
true, anyhow.  I won't go into the fan either, because it's my personal opinion
that there are a large selection of good fans.  The item I want to extoll is the
Ultimate 120 heatsink from Thermalright.  Huge heatsink, and the 120mm fan that
you get separately mounts on the _side_, not the top, like you might be used to.
 One look at this, at the great engineering ... well you might possibly find
something else as good, but I bet you'd not be able to find anything better.
Get that installed, and you can be really certain you didn't short on the CPU
