If a computer isn’t too old, there is no reason for any hardware problems…unless you installed it yourself and made a boo-boo! This happens because your hardware becomes overheated.
Hardware becomes overheated due to poor airflow inside of your desktop PC case. It’s like a person, about to have heat stroke because it’s been sitting in heat for long periods of time…so how would you help the person?
Give him some water and a nice cool breeze! Of course I’m not saying to give your computer some water, but instead of water you can try cleaning it of dust and debris buildup every so often. As for the cool breeze, your case fans should take care of that for you.
So as you have learned, one of the main causes for hardware failure is poor airflow in the computer case. Airflow is as important to a computer as food is to people.
Without the proper airflow, your hardware will end up getting stale air instead of fresh air, and will increase the build-up of dust. Newer desktop PC cases are focusing on good airflow since this issue is becoming more and more common.
When looking to buy a new desktop PC case, or even just concerned with your own PC’s temperature, be sure that it has the proper airflow needed.
Desktop PC cases should have at least 3 fans/vents built into the case. You should have one fan placed in front of the case so that it can blow fresh air into the case.
You should also have a fan in the back of the case, blowing the air inside of the case out (PSU’s typically have a fan built in that also sends air out of the case. This creates a good airflow throughout your entire case, always keeping the air fresh and it will prevent dust from building up quickly.
Most of the newer cases also keep a fan on top of the case, this is called a blowhole. Just like any other blowhole, it shoots out air; this allows the air above the motherboard to rise outside of the case to prevent dust buildup. The most important fan inside of your computer is your CPU fan, this is because your CPU is the hardware that performs most of the PC’s tasks, and therefore it gets hotter.
You should always have a fan blowing directly onto your CPU.
There are other alternatives to cooling your system rather than setting up fans in the correct positions to make sure you get the correct airflow, but it’s the cheapest method and it gets the job done.
There is also water cooling, which is when water passes through hoses making sure the temperature stays cool. Water cooling is more expensive and is a hassle to install, but it is much more effective than traditional fan cooling. A method that is becoming more popular and is the most expensive is Liquid Submersion Cooling, submersing the hardware components in a thermally conductive liquid.
This method is the most effective and there is no need for fans or pumps.
