The kit is meant to work on a naked P3 SECC2 (slot 1). So you
will need to remove the plastic cover from the CPU. This is
very easy to do. The plastic cover is held on the CPU by two
pins going through the CPU. You have to squeeze and push them
out of the CPU.
peltier unit itself will also need some preparation. You have
to apply some silicon all around the unit, between the two ceramic
plates. This will prevent condensation formation inside the
peltier. A tube of silicon is supplied with the kit so this
is no trouble.
will also have to identify the hot side of the peltier. If you
install it upside down you will burn your CPU in seconds. Take
it in your hands and plug it for about 2 seconds. You will immediately
see witch side is hot. Don't ever let the peltier run for more
then 2~3 seconds without a heatsink on the hot side.
