In this lesson, we're going to install

active cooling for our CPU,

as well as some passive cooling

using a heat sink and thermal paste.

Then, we're going to install a few case fans for active cooling

for the rest of our motherboard and associated components.

Now, when you're installing a CPU,

you're first going to place the CPU into the motherboard

by aligning it into the processor socket.

You could see we've already done that here.

Once installed, you're going to apply thermal paste

to the top of the processor.

The thermal paste is a chemical compound

that's going to be used to ensure

that we get the best heat transfer

from that CPU or processor outward and upward

into the heat sink by eliminating any small gaps

or air pockets that could be developed.

This is important because the first step in removing heat

from the processor is to use passive cooling

through convection.

And so it's going to go from the processor,

through the thermal paste, into the heat sink.

Now, once that thermal paste is applied,

we're then going to insert the heat sink

on top of the processor,

and this goes on top of your thermal paste.

This is going to increase the surface area

that's being exposed to the cooler air within the case

and helps to dissipate away

all of that extra heat from the processor.

But your thermal paste and the heat sink

are not usually going to be enough

to dissipate all of the heat generated

by a modern computer processor,

so we also need to install an active cooling system

by installing a CPU or processor fan

on top of the heat sink.

This will pull air over the heat sink

and help to rapidly cool down the CPU.

All right, now I talked a lot about the processor

and cooling, but we're not going to install that yet.

First, I want to do the cooling fans,

and this is going to be for the case.

Now, the reason I'm going to do the cooling fans

for your case first

is because otherwise, that CPU processor

is going to get in the way,

because it's a big honking unit like this

and this makes it really hard to get to the cooling fans,

which on this case, there are six of them,

one on the rear, two on the top and three on the front.

So we're going to go ahead and install those now.

Now, when you open up the box,

this particular one does come with a choice of colors.

You can have white, yellow, blue, green, red, or black.

Now, I'm not really a huge fan of colors

and components on computers, but for these particular fans,

you will choose the color you want

and put it on the side of the fan.

This is actually a rubber-type device

that's going to help prevent vibrations

from when the fan is moving

and rattling the case and making a metallic noise.

So I'm personally going to go with blue

because that's my favorite color,

even though I'm not a huge color fan.

Now, once you pull everything out of the box,

you're going to start with your case fan.

Notice, you do have a cable connecting from this case fan,

and it will connect down to your motherboard

where the fan plugs in and I'll show you that in a moment.

Now, the first thing I'm going to do is I'm going to place

my four colors on here, which I chose to go with blue.

You'll notice on this fan,

you have two sides, one with the label and one without.

I'm going to go ahead and use the side with the label

and I'm going to face that outward on the back of the case.

So first, I'm going to put in my colors,

which in my case are blue.

And when you're dealing with these,

you're simply going to push the two little nubs

into the holes and push down until they push and click

and that will put them all in place.

So now I have my four rubber knobs

all the way around this cooling fan.

Then, I'm going to go ahead and face this upward

so that when the case,

right now it's laying on its side,

it will go into the back of it

and you're going to screw it from the outside going in,

so I'm going to walk around and show you that

as I screw this in.

Okay, so we're going to go ahead and put the case fan in.

I'm going to center it here on the rear case part

and I'm going to make sure I line up my holes

and then get that first screw going.

I'm just going to finger tighten it at first,

so I don't drop it.

And then again, I'm just going to go ahead and screw this

using my screwdriver right into the case fan.

And you're just going to center it on this back grate.

I'll do that with the second one.

And once I get both of these in,

I should be able to let go of my hand from behind it.

Now, some people ask why don't I use a power tool

like a drill, screwdriver or something like that?

Well, the problem is when you use something like that,

you can either over-torque it and break things off,

or they also create an electromagnetic field.

And so when you do that,

you can actually short out circuits on your motherboard

or your processor or other sensitive components.

So I always use a hand tool when I'm putting these in,

but some people you will see use an electronic tool

and it's not a best practice,

so I do not recommend doing it.

And this is the last screw.

Each case fan does require four screws

to be properly set in place.

And once you have that in,

you can then just give it a little twist

and make sure it's not moving.

It's nice and secure, in this case.

And now, I'm going to go to the other side

and show you how we plug that case fan

into the motherboard to get power

later on once we connect our power supply.

Now, again, there are six fans that can go on this case.

We just installed the first one,

so now we want to go ahead and plug it in.

You'll notice up here

close to the rear port cluster is four pins sticking up,

and next to it, it says sys fan 6

which is our sixth fan or our rear case fan.

So we're just going to go ahead and take this,

and we are going to go ahead and put it in place.

You will notice right here,

there's a notch on the back of it.

And what you want to do is line that notch up

with the pins because there's a notch also on those pins.

So I'm just going to go ahead and do that.

Line those pins up

and then you just push down and it will click into place.

Don't worry too much

about this cable sitting here right now.

Later on, we'll move all the cables around,

bundle them together with zip ties

and keep them out of the way for proper cooling.

But for now, I just wanted to get it in there

and plugged in, so I've done that,

and I'll just push it over here to the side

to get it out of my way.

All right.

The next two that we're going to do

are going to be here on the top side.

On this particular case,

there's a mesh netting, and I'm just going to pull that off,

that uses magnets and put that to the side.

Notice we have these tracks

and that's where we're going to screw into.

On the top of the computer,

we're only going to have two fans.

Notice we have three strips here.

When you put the fans in, we're going to put one here

with four bolts and then one here with the other four bolts.

I'm going to go ahead and do that in fast speed for you

so you don't have to sit here watching me

screw these things in for a long time.

Okay, now that we've gotten the two case fans

on the top of the case in,

we need to get the three on the front of the case.

Now for the two on the top of the case,

we're also going to make sure we plug those in

exactly where they say system fan on my motherboard,

which is on the front edge of my motherboard

and it's going to be done the exact same way.

We're just going to go ahead and put those four pins in,

line them up and click.

And we'll do the same thing with the other one.

And click it into place.

Okay.

Now, the next thing we're going to do

is we're going to grab this next fan

and we're going to put these three on the front.

I'm going to start on the lowest part of the case

which is all the way down here, and then move myself

over to the middle and move myself up to the top.

And again, on this case, we can see over on this side,

you can see here that we have this grate on the front,

and on this case, if we just pull it,

it comes right off and it's held in place

by these little notches into those catches.

In addition to that, we do have this grate in the front.

And again, we can just grab it and pull it off.

And that makes it easier for us

to be able to screw those case fans from the front

and we're going to have them facing this way,

so they're blowing air, they're sucking air

and then pushing it out throughout the case.

Okay, we're back.

Now, what I've done is I've put in those three case fans

which are sitting here on the front of the tower,

and you'll see that I do have the three cables.

Now up here at the top,

we're again, going to plug in our system fan.

We have a couple of places here.

The first two are at the top part of the motherboard.

I'm going to do that here and here.

And you're just going to make sure you line those pins up

and put 'em down.

And then my last one is all the way down here

on the bottom center, which says system fan number four.

So I'm going to go ahead and plug that in over there.

Okay, so now we have all of our fans plugged in.

We have six case fans all properly plugged

into the motherboard.

None of them have power yet

because we haven't put a power supply into this computer yet

but we'll get to that in another section.

Now, the last thing we need to do in this particular video

is go back and give cooling to that CPU right there.

Now, what I'm going to use for this

is actually a Dark Rock Pro 4,

but you can use any cooling fan

that's appropriate for your processor.

Now you may be wondering

why do I have six cooling fans in this case?

And do you really need all six cooling fans?

Well, that depends what you're putting in the case.

We're putting a pretty beefy processor into this computer,

so we're going to need a big heat sink with a big cooling fan

and lots of case fans,

because I'm also going to be putting in

a pretty powerful graphics card.

Now, this particular system could have used liquid cooling

or active cooling, but for our examples,

I wanted to keep us with active cooling,

because if you're working in the business world,

you're more likely going to be finding

active cooling in your system.

If you're working with a standard HP or Dell computer,

normally you're going to find yourself

with about one or two cooling fans in those cases

because they tend not to be very powerful units

in most office environments.

All right, let me go ahead and unwrap this

and I'll be right back.

All right, we've unpacked the box,

and one of the things I want to point out

is that often with these heat sinks, they will make them

so they can work with either Intel or AMD processors.

And that's the case with this one.

So inside, they actually give you two packages.

One is labeled Intel and one is labeled AMD.

Now, because we're using AMD, I don't need the Intel one,

so I'm just going to throw it over there.

All right.

Inside the AMD one, the first thing we're going to do

is we're going to remove the retainer clips right here.

On either side of the processor,

you'll see these plastic retainer clips

that are in the way and instead, we want to replace them

with these specific AMD brackets for that heat sink

because that is a beefy heat sink

and we need to make sure it can be properly mounted

on top of that processor.

Also, you'll notice at the bottom,

this is where the processor's going to be mounted,

right on here, and they have a protective coating on it

that we're going to rip off

once we put our mounting brackets in the right place,

our thermal paste, and then our heat sink,

and then that goes through these, into this heat sink area

and fans will pull the air out of that

and get all that heat from the processor

out where the case fans can take over

and push it out of the system.

Now that we've gotten our heat sink unpacked,

we're ready to go ahead

and install it on top of the processor.

Now, you'll notice here on top of the processor,

you have two plastic retainers that are sitting here.

So what I'm going to have to do is actually unscrew

both of those retainers

and replace them with this metal retainer

that came in my package for AMD 4 socket sets.

When I do this,

the little notch is going to be towards the processor

and the heat sink is going to bolt onto these.

There's going to be one on each side of the processor.

Now, when you do this, there's actually a retaining clip

underneath the motherboard,

so I'm going to go ahead and take off the back of this case

and show you what that looks like.

Now, here on the backside, as I unscrew this case,

I can, again, just pop that side off,

and I'll put that to the side.

And then here, you can see that we do have

this retaining piece right underneath the processor.

And this is where those four plastic retaining screws

are going to be.

So what I'm going to do is I'm actually going to put my hand on it

from this side while I unscrew it from the motherboard side

to make sure that it doesn't go anywhere.

Okay, so I've undone that screw part

and I'm going to be mounting on the metal bracket

from the other side.

So what I'm going to do is I'm going to go ahead

and turn this around so you can see me

mount this metal bracket.

Now, before you put this metal bracket on,

you need to use some spacers.

So in your package, there will be some spacers.

Now, what I'm going to do is just open up that package.

And then you have these long screws and these spacers.

So what I'm going to do is I'm going to put the screw

through the metal bracket.

I'm going to put it into the spacer,

and then I'm going to go ahead and screw it in from this side.

Now, you'll notice that there is just a very tiny little bit

of the screw hanging out once you put that spacer on.

So what I'm going to do is just go ahead

and put it on my screwdriver here.

And

I need to also make sure that mounting bracket

doesn't go anywhere on the other side.

And then I'm just going to give it a little twist here,

and it'll go into place.

There we go.

Now I need to do the same thing for the other side.

So we're going to go ahead and twist that up that way.

I need to go ahead and get this

spacer in there.

And then put the screw through the spacer.

Now that I've gotten it started,

I can use my screwdriver for the rest.

And again, you don't want to go too tight

and crack your motherboard,

so just lightly do it with your two fingers.

Next, we're going to take off the other retainer,

which is right here.

And there we go.

And go ahead and grab the other metal bracket.

And I'm going to put my screw through there

and my spacer through there.

And again, I want that little notch to face upward,

so I'll just go ahead and put that in there.

Go.

And then, I need the other spacer,

which will be right there.

And there we go.

Okay.

Now that I've gotten it started,

I can use my screwdriver for the rest.

There we go.

And I'm just going to make sure it's tight on both sides.

And again, just finger tight with your two fingers.

All right.

So now that we've done that,

let me go ahead and put these other parts

in the plastic retainers off to the side.

We are now going to go ahead and put on our thermal paste.

Now in your container,

you get this little syringe-looking thing.

And inside of it is this gray thermal paste.

Now, I want you to be careful with this.

You don't want to get it on your hands.

You don't want to eat it.

If you get it in your mouth for some reason,

you need to immediately wash out your mouth,

drink lots of water and contact Poison Control

'cause this stuff can be dangerous.

Now what we're going to do is we're just going to put

a little bit of this on our processor in the center.

When I talk about a little bit,

what I'm really referring to here

is just about the size of a pea,

and we're going to put it right in the center.

And then when we put our heat sink on,

it's going to squish down and spread out that thermal paste

into a nice small layer for us.

So there's a little tip on this.

I'm just going to go ahead and twist it off.

Okay.

And then, we're just going to go ahead

and put a little bit right here in the center.

And there you go.

So you can see here, I've got

basically about a pea size right there on the processor.

I'm going to go ahead and zoom in real quick

just to show you a closeup of that.

And now you can see it's basically

just about the size of a standard green pea

you might have in some fried rice or something like that.

All right, once you've done that,

you're going to pick up your heat sink.

And on the bottom, we're going to peel off

that clear plastic that we had

to make sure we have a nice clean bottom.

Now, once we've done that, I'm going to go ahead and pull this

out to the side and you want to locate

where your CPU fan is going to be.

On my particular motherboard,

it's actually here on the top of the case

is where the CPU connector is going to be.

I'm not going to plug this thing yet because on this one,

we're actually going to have two fans,

one here and then one that slides in between.

And that way, as air is coming up from the processor

with that heat transfer,

air can be pulled away from it this way

and pushed out this way,

so it's in both directions away from our processor,

and so we're going to have two of these cables

that are going to go through this Y connector

and plug into our motherboard.

So now that I've done that,

what I'm going to do is I'm going to line this thing up

and I'm going to make sure I have it in the right direction.

Now you'll notice, we have those two holes on either side.

And what we're going to want to do

is be able to mount them using these two

going all the way through.

So now that we have our mounting bracket,

we're going to take our cooling fan.

We've applied our thermal paste

and we're going to go ahead and put this into position.

Now on the top, you're going to notice these two knobs.

We're going to take those off.

And this is going to allow us to attach our mounting bracket

on the inside once this is in place.

So here at the bottom, you'll see there's a notch here

and this is going to go over it

and that's going to be able to screw down

to those mounting brackets that we just did.

But you could see it'd be really hard to get to

inside of the computer,

so we had to put a really long, small screwdriver

through that hole and then put those screws in place.

So what I'm going to do is go ahead and put this in here.

Go into position this

into the case

and place it directly on top of the processor.

Now that I have done that,

we're going to go ahead and put this mounting bracket

right in between.

Going to put that mounting bracket right in between there.

And then get that screw into place.

Okay.

Now that we've gotten that screwed in,

we'll just put our caps right back here on the top

so that they are out of the way.

And then, we need to put our fan into place.

So what I'm going to do is I'm going to take my fan

and I have the be quiet! side facing me on this fan,

and so I'm going to do the opposite on the other way,

so that the quiet is going to be facing out on the other way.

That way, air will go one way

and air will go the other way

to be able to push it out of the way.

I'm going to go ahead and feed that cable through.

And I will go ahead and plug that in afterwards.

And then we're going to slide that into place.

Now, once you slide that fan into position,

you're going to take your retainer clips,

and what you want to do is grab it on your heat sink

and pull it towards you and it will catch on there,

'cause there's a little lip.

Once you've done that, you can hold the fan in place.

And what you want to do is get it

to catch onto the corners of that fan.

There's a little hole on each side

so you're just going to do that,

and that will allow it to stay into position

without moving once you have this locked in place.

And you'll do that on both sides,

and at that point, you will have

your active cooling in place,

because again, you have your processor, your thermal paste.

Above that, you have your heat sink

and then these two fans that are then going to be connected

into the Y adapter, and from the Y adapter,

we're going to plug that into the motherboard

where it list the CPU fan.

On my particular motherboard,

that's actually in this back corner

just underneath the CPU.

It's kind of hard to see and hard to get to,

but you're going to be able to see it there

before you put that heat sink in

and then you'll be able to get to it

right here on the corner

and you'll have to just kind of twist your fingers

to get it in place.

I have larger hands, so what I'm going to have to do

is actually get a pair of tweezers to hold it

and put it into place and get it there properly.

Now remember, when you're installing a CPU,

you have four parts that must be installed

in the proper order in order to properly cool it down.

First, the CPU.

Then, the thermal paste.

Then, the heat sink.

And finally, the processor's cooling fan.

Keep these four parts and their order in mind

as you get ready to take the certification exam.
