How To Prevent Overheating Of Your PC's Internal Parts 

People who use their Computers for hours and hours always have a chance of getting their CPU fried due to Overheating. As PCs contain a lot of parts inside it, almost all of them generate heat when your computer is on. Some parts, like the CPU and graphics card produce too much heat, when the computer is on for too many hours. In a properly configured computer, much of this heat is moved out of the computer's case by several fans. If your computer isn't removing the hot air fast enough, the temperature can get so hot that you risk serious damage to your PC.

Causes Of Overheating:
  • Blocked or Malfunctioning Fans. The processor, some video cards, and even the CPU case itself have fans; however, when one or even all of them get blocked or damaged, insufficient air is allowed to go in or out, causing dangerous heat buildup. Dirt, dust, and other particles may stop the fans from working.
  • Improper Air-flow. Even if your fans are working properly, when cables and other peripherals are improperly arranged, they may block the airflow resulting to overheating.
  • Overclocking. Overclocking or “OC-ing” is a tweak done by enthusiasts to increase the speed and performance of their machines. It involves the modification of the voltage and frequency of the device, causing more heat. Overclocking needs high-performance or customized cooling systems. Without them, the system will surely overheat.
  • Location of CPU. The location of the CPU is also a factor for overheating. If the case is placed at a small crowded area, chances are, the generated heat cannot escape and proper airflow is restricted, rendering the cooling system useless.

The Dangers of CPU Overheating: 
There is a limit on how high the temperature each hardware can tolerate. Once the temperature goes over that threshold, things like these can happen:

  • Melt your device. Excessive heat may melt plastic components. For example, a processor with a jammed fan may melt the socket and even the motherboard, making it useless.
  • Shorten its lifespan. Some devices may be able to endure overheating but may have a severely shortened lifespan. An overheating video card may last only for a year or less rather than several years.
  • Cause fires. Cables and shells in your CPU may melt, short circuit, and later catch fire when the system overheats.
  • Consume a lot of electricity. When a device overheats, it becomes less energy efficient, consuming more power than usual.

Common Signs of Overheating:  
It is hard to know if your computer has a cooling problem. In some computers, you will only know that it is overheating once it's too late. Newer models have security measures that can detect temperatures when these are getting too high. Here are the common signs:
  • Hot exhaust
  • Frequent and sudden restarts
  • Frequent shutdowns
  • Noisy fans.

Getting Rid of Overheating:
Overheating not only damages your computer, but can also cause a big dent in your pocket when the electric bill comes. Here are some tips to prevent overheating:
  • Clean the CPU regularly. Dust and dirt can accumulate inside your computer and later block openings and fans. Use a brush and some pressurized air or a portable vacuum to easily remove those potential blockages.
  • Rearrange the cables. Arranging the cables in your CPU will greatly help reduce the amount of heat that gets trapped inside. IDE cables, floppy cables, and even the cables from the power supply should be arranged in a manner that it does not restrict or trap air flow from the cooling system. You can replace your Flat IDE cables with the round type so that it does not trap heat. If you have more than one harddrive, you may want to put them slightly apart.
  • Invest in a better cooling system. If you have high-end computer hardware, invest in a good cooling system. You can either go cheap by buying extra heavy duty fans or go hardcore and buy pricey water or gas cooling systems.
  • Let the CPU “breathe”. The place where you put your CPU matters. Don't place it down under your tight desk nor place it inside a closed cabinet. Place it in an area where its fans can get enough cool air inside the case plus enough space to throw out the warm air from inside.
  • A Temporary Fix When you don't have enough time or money to fix your computer's cooling system, a good way to temporarily get rid of overheating is by opening the case. You can then face an electric fan directly in front of it to cool it down as you use the PC. Just make sure you close the case right after you finish using your computer to prevent dirt and other foreign objects from entering it.

Summarizing The Tips (Given Above):

  • The easiest thing you can do to keep your PC cool is to give it a little breathing room by removing any obstacles to air flow. Most of the hot air flows out of the back end of the computer case. There should be at least 2 to 3 inches open on either side and the back should be completely open and unobstructed.
  • The Fans inside your PC are Responsible for Keeping the computer cool. Try to Clean them every once or twice a week to remove dusts, etc. These dusts slows down the fan and eventually makes it stop.
  • Replace the Fans with new ones if the old one doesn't work properly or gets partially burned.
  • Always keep your computer in a clean, well-ventilated area.
  • Open your PC's case once or twice a year and use a computer vacuum or can of compressed air to clean out built up dust and debris.
  • If your computer still getting heated with its built-in fans, get a small, external fan to blow into your computer.
