Computers, when being used, generate heat. Specific parts of the computer, such as its processor or graphics card, are some of the components that generate the most heat. Those usually even come with their own heat sink to prevent them from breaking. But most users, if not all, will eventually experience trouble with their computers due to overheating. The best option to remedy that, is of course, to remove all of the excess heat, and that's where you need to do something about helping your heat sinks to do their job.
There are various ways for you to cool your PC, one is through a PC cooler, and another is by the computer's heat sink/s.
A PC cooler is a device in the System Unit which caries heat away from the inside of the PC. It's usually a moderately sized fan located on an available space on the case.
A Heat Sink is a device that channels heat away from certain components. Those components may range from a single processor, or something not even related to computers, such as components of a car. The method of how Heat Sinks transfer that heat may vary, as some would use a fan (quite common) while others may utilize liquid.
Coolers and Heat Sinks are there in the first place since certain parts of the computer tend to generate lots of heat due to use, and they need something to dissipate that heat. As said earlier, examples of these are the processor and graphics card (some graphics cards don't have heat sinks though), which are some of the most worked-out components of a computer. However, it should be noted that most, if not all, parts of the computer generate heat.
Heat can have certain negative effects on a PC or Laptop, with the latter holding a more significant claim to that statement due to its structure. Common sense implies that heat can fry/melt/singe stuff in the PC, and that holds true, and that's what's making heat a big problem for computers. PC and Laptops are built with some sort of fail-safe or countermeasure (such as shutting the computer down without any prompt) to prevent heat from doing something significant to a PC but chances are is that when that triggers, it means that the heat generated by the computer can no longer be handled by its heat sink and/or cooler, and that would be dangerous if a user experiences that regularly. If a user experiences sudden computer shut downs or the like due to heat on a regular basis, then things inside the computer might start to break, and since heat travels from one place to another, a lot of other parts might break as well soon after. Therefore, when that happens, you need to do something to get that excess heat away (unless you really intend on sniffing barbeque, which we highly doubt).
Another problem because of that is when the computer's cooler and/or heat sink/s can no longer sustain a satisfactory temperature, additional heat sinks and coolers require quite a bit of money, and one also needs to take many things into account and consideration, such as if the thing will fit in properly, how much more it will contribute to the electric bill, if it's even available etc.
However, we've found a remedy to that last problem, that may even remedy any computer heat related problems a user may encounter without too much of a hassle. A homemade computer cooler will allow a user 100% control on what he/she wishes to implement on a heat removing device. It's one of the best things a user can do with little to no spending, since implementing a homemade heat sink can have potentially dangerous outcomes.
Step 1: Precautions and Materials
One might ask, "Can we make a homemade heat sink? And why is it dangerous?"
Firstly, of course, but we highly recommend that if you are indeed going to make a heat sink yourself, then it might probably be best to leave things that require a heat sink alone (in other words, don't). Heat Sinks are built in a way that requires quite some precision, since they're cooling specific components, of which most easily break. Chances are is that if you're going to make a homemade Heat Sink is that you might encounter serious problems when you integrate it to your computer, unless you really know what you're doing.
Now that that's dealt with, the cooler we will be teaching you to make can double as a laptop cooler, and any improvisations for that will be discussed along the way.
You will need:
Wood, preferably small, long blocks, though other hard materials can do, since this for the frame.
A small fan, though not too small, of course (unless you're planning on making a laptop cooler instead of a computer cooler). This is the only thing you probably have to buy, but it's rather cheap. You might probably find some in your house though. You never know. Oh, it's also recommended to have more, since it definitely helps
Small metal bars, this to protect the fan from objects that might for some reason try to go through it, or to protect other objects from the fan should it "decide to fly."
Heavy Duty Glue
USB cable, if you want to plug it on a USB port instead of plugging it on a socket or something.
Any measuring device, to know how big things are
Solder, for connecting wires.
Electrical Wires, for expansion or other stuff
Electrical tape, for holding them safely together
pliers, go crazy, but not too much
