Keep Computer from Overheating

Keep Computer from Overheating

Have you ever been in the middle of setting the newest high score or completing your almost due assignment and had your computer become unbearably slow, and begin glitching? just freeze? or completely black out on you?

If you have, I can testify to the whole new level of frustration you have been experiencing, for I myself, have been in similar situations more times than I would care to count.

The issue we’re experiencing here is overheating. Further along the article, I share some things I’ve done to keep computers from overheating and I’m absolutely positive that they will work for your computer as well.

If there is no problem at all with the software or applications that you use, you have come to the right place for solutions.

Here at My Computer Talk I, as much as possible, try to advocate the simple things that we as end users tend to ignore that come back around and bite us in the heel!

(Hence the site name: My Computer Talk – The Simple Things) … that’s beside the point.

The advice I give here is backed by; 1. My personal experience and 2. Researched knowledge.

Keep computer from overheating.

So, what are some things I’ve done that you can also do to keep your computer from overheating?

  1. Use External Fan USB Fan.
  2. Check and clean internal fan.
  3. Avoid doing certain things with your computer.

Note that there are other complications (and hence more advanced solutions) that may arise due to prolonged overheating of a computer, such as the degradation or complete and utter destruction of other components on the motherboard due to burning or melting etcetera.

However, this article is for those who are not entirely reckless users and can identify when a problem is occurring, no matter how small, and are trying to rectify it. Good on ya!

Use an External Fan.

Notice that wherever you are using your computer, the general area or work space tends to heat up.

If your office or work area has air conditioning or is generally a cooler than average working area, then this isn’t much of a problem for you.

Otherwise, after the prolonged usage of your computer, your environment heats up and becomes not-so-conducive for both yourself and your computer.

A mini desktop USB fan (i.e. an external fan) is a small, portable fan that can be powered by your computer via the USB port. These fans are a great investment for yourself and your computer.

Check and Clean Internal Fan.

This is usually a task that I advise you seek professional or expert assistance if you are in no position (i.e. not have the know-how) to do yourself.

In your average computer – desktop or laptop, the internal fan is placed on a heat sink over the CPU (Central Processing Unit). The CPU is the sole component responsible for carrying out the actual ‘computing’ in a computer.

It is responsible for processing what happens when and how. It is usually referred to as the “brain” of the computer, does most of the work and hence, heats up faster than any other component.

Overtime, as we use our computers, the fan tends to accumulate dust. If your computer is experiencing overheating regularly, the fan is most likely not working at its full capacity because of accumulated dust around the fan blades and the heat sink.


If your computer is a desktop computer, cleaning out the fan would be fairly easy. The chassis when opened should then show you the mother board on which the fan should be easily identified.

Using a can of compressed air the dust from the fan and the heat sink can be easily blown away.

IMPORTANT: Make sure your computer is turned off and disconnected from the power supply and you are well and truly grounded before opening up any component of your computer.

Also remember, a static discharge is important before opening the chassis and can be simply done by rubbing your hands together and placing them on the metal part of the chassis.

Otherwise, you may damage other components while trying to eradicate one simple hindrance. You can always ask help from someone with a little experience to help you if this seems like an overwhelming task.

However, if you own a laptop you should ask assistance from someone who has experience with opening up a laptop of your model as laptops are slightly more challenging than desktop computers and will take experience and /or patience to figure out.

Note that in an average desktop computer, a fan will be used to cool the PSU (Power Supply Unit) as well. While cleaning out the fan over the CPU using the compressed air there is no problem with going ahead and cleaning out other components you see that have accumulated dust.

But always remember, : Be careful and if you’re not comfortable doing it yourself, your neighbors teen might be able to. Otherwise, there are people who are paid to do the job for you. 🙂

Avoid doing these things.

A couple of things that we should avoid doing for the safety and health of our computers. These DON’T’S are small things that we tend to get careless with over time.

Avoid doing the following;

  • Running many applications simultaneously on your computer.
  • Placing computer (laptop) on cushy or plush surfaces that cover up the air vents.
  • Leaving on computer for indefinite periods of time or not shutting your computer down correctly.

It is okay to run applications you need to run to get a specific job done, but avoid leaving them running and moving to the next thing. Close applications, windows or tabs that you are not using to save virtual memory and processor power.

If you leave applications that are not being used running, your computers processor works double time to keep that application running AND whatever other application you are actually using.

If about 50% of the processors power is used to keep all these applications running, you are tasking your processor to work for more than you need and at the end of the day only 15% to 20% of that 50% was productive.

The other very obvious DON’T would be to not to place your computer on plushy surfaces like on your bed on the sheets. The sheets cover up the vents and the hot air produced by the processor is unable to leave the motherboard “efficiently” thus spiking the heat levels within the computer.

Lastly, but not least would be to make sure that you shut down your computer when you are done with what you’re doing. Otherwise, similar to DON’T Number 1, your computer’s processor will be working for more than you need.

It’s really that Simple!

So its not an entirely complicated issue even though the consequences seem pretty drastic. A less intrusive solution to your problems is a mini USB fan.

If however, that would be to not a suitable solution for you, consider having your computer cleaned or ‘aired’ out (being mindful of the risks against you and your computer and follow safety regulations).

Otherwise, the best advice I can give you to avoid overheating computers for as long as you can, is by being mindful of how you use your computer. Like the saying goes, prevention is better than cure!
