PC enthusiasts have been looking for ways to keep their rigs from turning into little mini ovens or large ovens as it were for a very long time. And even people who aren't tech heads have had to fight smartphones, game consoles, or even televisions that get too hot. But while there's plenty of discussion online about how to set up the most effective cooling solution, a question you don't often see asked is why the heck do our electronics heat up so much in the first place? Okay. Well, before we dive into the specifics, it's important to understand one of the fundamental laws of the universe that ultimately causes heat generation, not just in computers, but in everything from car engines to light bulbs. I'm talking about the second law of thermodynamics. And while there are a bunch of smart guy sounding ways to state the second law, for the purposes of this video, it's pretty easy to understand. Whenever energy is used, some of it becomes waste heat. Now, we could just say that since electronics use energy and therefore generate waste heat, they need to be cooled and end the episode there. I mean, I'm feeling kind of hungry. Lunch break, right? But we're all about viewer satisfaction here at Tequicki. So, let's dive a little deeper. If you watched our previous episode about motherboard components right up here, you'll remember that nearly all electronic circuits feature resistors to limit the flow of current so that the sensitive parts of your system like your processors and RAM modules get the correct amount of power since too much can cause them to function incorrectly or even damage them. And this energy that gets resisted has to go somewhere. So, it ends up as heat that needs to be dissipated. And with as many resistors as there are in modern electronics, that heat adds up pretty quickly. But what about the hottest parts of your computer? Your central processing unit or CPU and your graphics processing unit or GPU? Well, processors are made up of millions or even billions of tiny transistors which switch on and off. you know, zeros and ones to run programs. And since modern processors run through billions of cycles a second, these transistors can generate lots of heat due to the extra current that they use while you're putting a load on your processor, such as while gaming or video editing or compressing files. The heavier the task you're running, the more of them need to be switching. And this is all happening within a space of a few square centimeters, necessitating those hunks of metal or heat pipe type coolers that come directly into contact with the CPU or GPU package carrying heat away usually to a large metal radiator structure to be dissipated into the surrounding air. Again, usually by fans. And this is interesting. Even if you're only using your computer for things like Facebook and Microsoft Office, you still won't get very far without a cooler as some current is always running through your processor. This is called leakage, even when it's idle. So, seriously, don't try it unless your goal is to start another one of those weird tech destruction YouTube channels.
