Overheating – The Summertime Headache

Many of us may have heard about overheating, even if not, many of us face problem of excessive heating of computer parts mainly in summer (I am one who used to live with PC that used to overheat frequently). Those who get their motherboard and PSU fried are probably the victim of overheating. For those who are new to computer technology, overheating is simply excessive heating of computer parts which sometime results in malfunctioning of those parts. Overheating is mostly prone to parts like processors, graphic cards, hard disks and power supply unit.

Now that you know about it, one may ask how does this happen. Well, the major factor for overheating is high working temperature i.e. temperature of your room or workspace. Other reasons may be dust and dirt clogged in components, lack of application of thermal paste in processor’s and GPU’s surface (and in my case too), failing or defective components and sometime also due to heavy tasking like multi threaded works or games.

How to know about it?
One of the easiest way to find if a component is overheating or not is to touch it with your finger and to see if it burns the finger (just a pun, no offence to anyone). While the above mentioned option is recommended to the braver ones, there are other ways to find it out.
1. Just enter into your BIOS setting and check the temperature of processor, motherboard etc.
2. If you want to play safe and not get into mess by fiddling with your BIOS setting, you can use one of many software like Speed Fan, which monitors temperature of your processor, motherboard and hard disk.
3. If you are too lazy to do the both, just relax and play some heavy games. If it’s overheating then the PC will shutdown. When you restart it, it will display a message stating that your computer is overheating. Voila, you have found about it without doing anything…. Err... (Playing isn’t doing work right?)
(By the way I found that my PC was overheating by the same way as above i.e. playing games ;) but it was two years ago).

Now to find what temperature is normal for PC and which is not, you can use index below:
1. upto 45 oC = it’s normal temperature, no need to worry
2. 46 oC - 70 oC= it’s pretty high but no need to hit panic button right away.
3. 70 oC and above = now it’s time to panic, run for your life!
(When my PC was heating it used to reach temperature up to 100 oC!!)

Read my next post to learn how to minimize risks of overheating your PC and getting stuck with a fried motherboard and processors.
Overheating - The Solutions


  1. Computer circuit contains large number of transistors and resistors, made from semi-conductors. The movement of electrons in semi-conductor results friction and friction momentarily results heat.

    Cooling pads for notebooks are very helpful to maintain the temperature. But it's notebook and most of them have battery life up to 2.5 hours (formal normal 6 Cell packed batteries) and that is how long the laptop must run.

    Another solution can be using latest products. If a program that requires higher specs is executed in lower end products then heating is obviously excessive.

    But for me, the best alternative to overheating problem is, TURN OF YOUR COMPUTER.

    NEA officially is helping us to reduce the problem of overheating by higher loadsheding schedules.. LOL

  2. lol, you are right NEA does one thing perfectly and that is power cuts.

  3. good article but could have been better. I'm waiting for your next post.
