today i'm going to show you how to cool
a cpu with a peltier plate
now what this is is this little
12-volt plate
if you heat it on one side and cool it
on the other it will actually create
electricity however if you pump
electricity through it one side will get
extremely hot and one side will get
really cold this is used in a lot of
different chillers and air conditioning
tutorials and a lot of different things
it pretty much uses the law of
thermodynamics to create or take in
electricity and create something cold or
something hot so what we're going to do
is we're going to be putting the cool
side down on the cpu and then we're
going to put a heat sink on the top
where it's hot to draw out the heat
essentially
air conditioning our cpu
now we do need a lot of different things
for this tutorial so i'm just going to
cut i got everything here on the table
i'm going to just try to bring it to the
camera and show you what you need
obviously you need a motherboard cpu
that you're going to be doing this on
uh you do want a fully functional heat
sink you want the pal tier plate
you want vaseline that we're actually
going to put on the board because since
it does get cold it does create
condensation we don't want to short out
the board you also are going to want one
of these little adapters because what
we're going to do is we're going to
actually draw power from the power
supply
to the peltier plate
and i'm going to be using a secondary
power supply you really don't have to
but it is going to draw a lot of power
from your power supply to keep that cool
and pump power through it
so to begin we're gonna put vaseline on
the motherboard
[Music]
now obviously you want to do some
testing to figure out which is the hot
side and which is the cool side usually
wherever the text is if there's any text
on it that's the cool side and the hot
side is the other side
so since our motherboard is prepared
we're going to go ahead and take the
little adapter
just gonna cut the ends off here
okay strip the wires down a little bit
and then just twist them on
red to red black to black
i'm probably gonna use hot glue or some
type of tape just to secure it i just
realized i'm out of electrical tape
so i'm gonna have to use scotch today
which is fine
it should work for our purposes
[Music]
okay so first thing we're going to do is
we're going to test to see which side is
hot and which side is cold
so the one i think is hot
i'm going to go ahead and put that on
the heatsink side so it has somewhere to
transfer heat
and we're going to be putting thermal
grease on there and placing that on
there and then i'm going to just kind of
lightly touch this to see if it's cold
or if it's hot
because
you don't want to do this very long
because if you have it configured
incorrectly you're going to burn out the
plate and the plate is useless
everybody's afraid of
thermal grease and thermal paste
just wash your hands afterwards it's not
a big deal
and that is exactly
a perfect fit for that heatsink that's
awesome
okay i'm gonna put this on
that actually got really cold really
fast
that's awesome
wow
okay onto the motherboard
make sure that's lined up good
[Music]
okay let's add all the other connections
and take this for a test drive
okay that was a lot easier than i
expected so i'm gonna turn on both power
supplies the one running
the thermal plate
peltier plate
and just making sure that that's lined
up okay because i don't have them
screwed down
and the one running the computer
hopefully this will work but we will see
it would help if i plugged in the
computer right
[Music]
here are the temperatures with the plate
[Music]
and here are the temperatures without
the plate
[Music]
so we had some interesting results with
and without the plate um to me just
using the machine itself it seemed like
it only took it down anywhere between 5
10 maybe 15 degrees which is a
significant improvement especially if
you're overclocking
however the extra power needed to
actually power
the cooling unit and also having to
worry about condensation honestly i
would recommend an enclosed water
cooling unit or a better fan and better
heat sink versus this but this is a
cheap way to make an old computer cool
down and run a little quicker as always
