Extreme overclocking entails extreme cooling, and extreme cooling would require some measures against condensation. Here’s a rather detailed condensation prevention guide.
Here’s my guide to insulation on PC hardware and cooling devices. First of
all, let me list out the materials that will come in useful when it comes to
insulation during usage of extreme forms of cooling on PC hardware.
This is one of the most common material people use for insulation. It feels
like a cross between sponge and rubber but air cannot pass through it as it
is closed-cell. The common way to use it is to have it in between the hardware
and a clamping device.
Neoprene clamped against the back of the socket
Or to wrap it around waterblocks or cold plates with tape.
Neoprene piping/tubing insulation:
This is very commonly used in the air-conditioning industry and is excellent
for insulating pipings and tubings. There are grey foam-like versions which
are even better at insulation but are more expensive.
These dense styro-foam sheets have great insulation capabilities
and come in many thickness.
Cork Seal tape or Seal String:
This is the Seal String stuff that the Prometeia uses. This is very useful
for hardware insulation, such as motherboards and video cards as it sticks
very well without the need for any clamping pressure. It also eliminates all
possible air pockets so condensation is avoided. It retains its stickiness even
under very cold temperatures. However, surfaces must be clean and oil/grease
free as it does not stick to oily surfaces.
not require any clamping device
sticks to your fingers
chance that SMD components on the motherboard can be ripped off if the solder
job was bad to begin with
The clear RTV sealant variant works very well at protecting hardware from
insulation. All air pockets can be eliminated with it and once it cures, it
stays there for good.
from condensation and corrosion
it gets on the array of pins behind the motherboard
The common essential stuff to use on CPU pins and motherboard socket holes
for prevention of condensation and corrosion. Also used as a general touch up to
areas where moisture is expected.
area of hardware
This basically works similar to dielectric grease, but its less liquidy.

The grease that we all use for our CPU and GPU cores can also be used to
eliminate air-pockets and prevent corrosion. Take note that it should be
something electrically non-conductive. Useful for areas around the core so that
thermal interface is still good even if some gets onto the core.
PCB lacquer spray:
A spray that coats surfaces with a clear lacquer.
it does not prevent condensation
The clear nail varnish that women (and some men) use for their manicure can
be used as a protective coating for your hardware.
