Insulation on the CPU side

Insulating on the CPU side is also quite important. Let’s take
for example the Intel P4. There are components below the CPU core. So flip it
over and cover these components with a layer of nail varnish carefully making
sure you don’t smear any onto the pins. If you do, just clean it up with nail
varnish remover. Wait for it to dry first. Then, if you choose to go the 200%
garantee against corrosion route, smear dielectric grease over all the pins
with a brush.

Now, you can place it into the socket. Hang on first if you have
removed the IHS of the P4. As we all know the CPU core is raised above the chip
and within these area is an air gap. Now, you can choose to eliminate this air
gap by doing what I do. I cut insulation tape and paste it around the core,
layer after layer until just a little below the height of the core.

Make sure no part of it gets higher than the core. I like this
method because it serves as a shim to protect the core from chipping as well.
The rest of this air gap can be taken care of by a layer of grease. For area
surrounding the core, thermal grease is recommended so that you don’t accidentally
get non thermally conductive grease over the core. Or if you’re lazy, just fill
the whole gap with grease.

Now for the AMD chips, the components are on top of the chip around
the core. So you will need to cover these with nail varnish.

Then you can double protect the pins by brushing dielectric grease
over them. And once you’ve fitted on the CPU, take care of the rest of the
air pockets between CPU and cooler with thermal grease near the core area and
silicone/dielectric grease further away from the core.

Once again, I bid you to double CHECK the base of the cooler for
a good imprint of thermal grease, an implication of good contact and mounting.
Once the cooler is mounted on, you can even triple protect by adding a layer
of seal string all around the bottom of the cooler and the motherboard to make
sure it is very air-tight.

The reason why I’ve gone so thorough is because it is better to
play safe and do a thorough overkill job once then have a lot of headaches when
you run into condensation problems because it is very difficult to trace the
problem area once everything is set up.
