welcome to lessen sixth out one cooling mechanisms for the CPU and system unit. This is part two so mentioned earlier about controlling the fan in the BIOS. And here's two different system utility setups where we can see where we're there's options if you can control the fan right here on the left is a gigabyte. You e f. I
00:18
setup Italy, and you can see that there is
00:21
different ways we can control the fan here. Normal, silent or manual or full speed. On the right is an Azraq system utility showing pretty much the same thing, but in a different way. So what? That extra pin we get Maur capabilities of controlling fan speeds and so forth.
00:42
Hate sinks. We briefly talked about heat sinks before
00:46
so he thinks are a passive heat exchanger, and you've probably seen these multiple times throughout your times inside of a PC or other electronic components. We're gonna get into what a heat sink actually does and how it does it. So basically what a heat sink does it dissipates. Heat away from the component.
01:04
It's the heat transfer principle
01:07
going a little bit of further. There is based on the offer's law principle. That is the the the principle of heat conduction, and I'm paraphrasing. So basically with that law, states is heat will travel from and hot source to a cooler source. So
01:26
if you have ah, component inside of your system, that's generating heat.
01:30
Ah, heat. Think on top of that or connected to the device would draw heat from the hot source, which is the internal component to a cooler source, which is the heat sink. So
01:42
with that leads to a question is, So what does he thinks used to cool hot components? How does it do this
01:51
cool air? So if you look at the heat sink picture on the far right, you can see that at the bottom of the heat sink is a a strip of metal that connects to the generating heat generating device, whether it be a CPU or GPU inside of your system. Then, from there we have these tiny fiends off of that base,
02:10
and there are gaps in between those two those fans on that device.
02:15
So cool air flows in between those fans cooling those fans. So if we go back to the heat transfer principle or furs law.
02:25
Basically, if you have that heat sink on top of a heat generating CPU, that's really, really hot and that in that process, that transfer principal says, basically, he travels from a heat hot source to a cooler source. If there's air flow flowing in front of those fans and in through the in between those fans, it's cooler.
02:46
So he will be wick the way or pulled away from that device to the fans, where the airflow is cooling off.
02:52
And if you step back for a bigger picture. If this is inside of the system unit case, which it is, you got the airflow going around inside of that case, and that air is being pulled in from the system from of the system circulated around there in the system case and exhausted out the back.
03:08
So thus that's your cooling for those even those systems,
03:12
and it's done with the heat sinks.
03:15
Also, you may see a heat sink with a CPU, and when it's paired with the CPU on in a combo fan combo like that, it's regarded as active cooling because it has an active fan blowing across those those fans
03:30
and talking about, he sinks. Let's talk about the thermal pace that you would use on top of the component and at the bottom of the heat sink. So thorough peak paste, also known as CPU Greece thermal interference material, heat, sink, compound and other names. That is the pace that you would put
03:49
at the bottom of your heat sink. That's on the top of your CPU.
03:52
So basically, it's not only he. SIV is not sticking that he'd sink to that. Are that CPU to eat? Sing so it won't fall off. Basically AIDS and connectivity, and it conducts heat. It's a conducts heat from the heat source to the the dissipation of the heat, which is the the fans or the heat sinks.
04:12
So it's used to eliminate air gaps in transfer heat from the heat generating component to the heat sink. So again, it's not an adhesive or paste or glue. It's it's forming a barrier that conducts the heat from the internal. Some device to those heat sinks to those fans.
04:31
And last but not least, let's talk about liquid cooling.
04:34
Liquid cooling originated in the
04:39
custom systems or gamer systems, and it's now becoming more prevalent throughout the PC industry. Yes, they're on higher in systems, but now you can get liquid cooling kids, or you could buy these components individually.
04:51
So bottom line is liquid. Cooling is a cooling process where water is pumped were sent into a water block.
04:58
Now that water block eggs, oars, the heat from the device that thermal heat generated by the system and his past toe a heat exchanger were fans blow cool air across the exchanger. The cool waters returned to the block, and the cycle repeats now. Like I said earlier, you could buy the entire kit,
05:15
which is shown any image down below, which consists of the radiator
05:19
and that heat block and the tubing, or you combining his individual components. So liquid cooling works on the principle almost like a radiator in your car. It has the radiator that it pulls the water in, and that the fans blow across and cool it and cycles it back
05:36
again. High demand systems, gamers, or when you're over clocking your PC when cooling is a must on when you're trying to get the ultimate and cooling in a system, liquid cooling may be for you
05:50
commonly used to cool not only the CPU, but the GPU as well. The graphics processor unit components of liquid cooling like a set consist of water block on a pump slash reservoir. And to be these components, like I mentioned before, can be purchased separately or, as in any kit.
06:11
So this is the liquid cooling for your system. You know, high end systems, game systems over clock in your CPU. And when you need the ultimate in CPU cooling liquid cooling may be for you.
06:25
Okay, so that's it for today's lesson. We talked about the cooling of the sea pews and the GPU system. Cooling basics win one over basics of Cooley. We talked about case fans and what to look for and what to know. For case fans heat sinks and thermal paste, we also talked about how he seeks work,
06:44
what, what they do and where you'll see those that and also liquid cooling for your systems.
06:49
Now going further, we're going to be discussing this faras custom PCs when he's setting what custom PCs. And some of these components are part of that liquid cooling specifically thermic thermal paste. Heat sinks. They're going to be a part of that. So this is key for further learning later on in the lesson.
07:09
So that is it for this lesson. We will see you in the next lesson.
