Laptop Is Too Hot - Cool it!

Here are a bunch of ideas to cool your laptop.

Firstly I use a chill pad that runs from a USB port. It goes under the laptop and allows it to breath and introduces additional airflow to the bottom of the laptop.

There are some pads that are just made to allow airflow with out active fans.

Are you using your laptop on the bed or on cloth? It wants to breathe just like you so let it.
Blankets keep you warm at night and so as they contain heat duh...
Your legs can block the airflow if you use it on your lap.

If you want to use a found object, use a tray top or a hard surface that will allow the heat dissipated by fans, to get through the vent and allow the bottom to stay cooler, as well.
It needs air circulation all around it.

Laptop CPUs.

Usually have max temp of 100C before shutting down.. more or less.
Once the laptop reaches a certain temperature, it will either throttle (slow down) or shut right down.

Gamers often like to get into the computer and overclock it to make it respond faster... that causes more heat from the CPU. If you are overclocking, then guess who is to blame for high heat.

For the most part, you should be able to get away with it to some extent although different laptops will have more or less or no tolerance to overclocking..

Some laptops overheat due to faulty fans.

Or, even chips, thermo regulators or especially blocked ventilation. You would be surprised at how much dust can accumulate in the venting system of the computer. Keep those vent ports clean.

Check the manufacturer's web site.

For more info. If you feel that you must, you can open it up (possibly violating any warranty) and clean out the dust.

Firstly unplug it and remove the battery. Let it cool until the hottest parts aren't hot. If you aren't using a brand new laptop, you will see dust.

The laptop is often working is dusty places although you don't realize it, and it gets in there.
That definitely causes heat build up. Most laptops have a large fan that cools the whole thing and a smaller one that cools the CPU.

My home desktop CPU provides the heat for the second floor in the winter.

Blow out the dust

With compressed air. You can get it in a small can from an office supply store. Don't blast the fan directly without holding it gently in place so as not to cause it so run faster than it was designed to spin.

If you ever smell anything like a burnt smell, unplug it, and if it is safe to do so pull the battery carefully, so as not to burn your hands. Check it.  Smoke and fire are a bad sign. You have a bigger problem than you can fix yourself. Most likely toast. Below is a checklist for common issues that lead to heat.. Scroll down for more info.

 
  1. Did you leave it in the car in hot weather?

  2. Is it sitting in the direct sunlight?
  3. Are you running it in a carrying case or bag?

  4. Did you spill something onto or into the laptop?

  5. Are you watching DVD's (that runs hot) in a hot environment?

  6. Are you burning multiple discs one after another?

  7. If you spilled something in to it after it is cleaned out by either you or your technician, you might at first smell some odor as it burns off the residue.

  8. Inside are there loose heat sinks?

  9. Do you have a battery manufactured by Sony?

  10. They did have a recall on one type of Sony lithium-ion battery.

  11. Has it been kept on a hot surface?

  12. In the summer, I have used a small desk fan on it as an additional method of cooling.

  13. In my work, I will run the computer actively for up to 6 hours straight, so it does have reason to heat up.

         I take all of the aforementioned precautions. So cool it.
