Keeping your laptop computer cool is important, use a laptop cooler, or a gas duster, or something
A hot laptop computer is not a good idea. Keeping your laptop cool is smart. Keeping a laptop cooler is easy with a laptop cooler and/or a gas duster.
There are plenty of laptop computer horror stories out there, many involving overheating machines. I have had a particular laptop computer that for about three years has now developed a severe overheating disorder. I have figured out ways to keep the laptop from overheating, without spending too much money. You can make your own laptop coolers if you are up to the challenge.
When you think about it, there isn’t much to a laptop cooler. It’s either a base with fans, or a base that simply gives more air-space to the bottom of the laptop.
Purchasing a cheap laptop cooler base is the easiest way to go
The most effectively cheap way, and the most time-effective way (you won’t have to build your own) to keep your laptop from overheating is by going out a picking up an fan-based laptop cooler. There are many options on the internet available for purchase:
- Here’s a laptop cooler for cheap
- Here’s a laptop cooler for a little less cheap, yet still very cheap
- Here’s a laptop cooler that has a multi-port USB hub, and it’s still really cheap
- Here’s a laptop cooler that doesn’t use fans
And then I ran across QuadCooler.com
- The Original Quad Cooler
- The Tri-Cooler
- The AOP Cooler (using Aluminum)
- The Big Brian
The stuff at quadcooler.com looked pretty sweet. And for kicks I also found a review site that looked promising as far as providing reviews of the quadcooler, but it degraded pretty quickly into a bunch of arguing about laptop coolers.
Are you thinking to yourself, “wait, these things look pretty simple, I want to make one”?
If you are you might want to check out this Instructables page about making your own laptop cooler. Or you might want to check out how to make a laptop cooler in about an hour and a half. Even if you don’t follow these instructions to make your own laptop cooler, these page might give you a good idea about what some other people have done to make their own. They might help you to get started on your adventures of trying to cool your overheating laptop, on the cheap.
My overheating story, it’s not that interesting
I have used a simple 2 fan device, powered by USB. It has worked fine, and kept my laptop from overheating. One of the fans eventually got clogged up with dust and needed to be cleaned. Then after that the fan did eventually just wear out. Now it makes all kinds of noise while it tries to spin. I’ll need to replace the fan or buy another. I’ll be looking into a fan-less unit this time around, mainly for power consumption reasons.
Even as much as the 2-fan laptop cooler was important to keeping the heat levels down on my laptop, using compressed air to clean out the air channels in the unit was just as much important.
Try this out: buy and use a can of compressed air, or more correctly a gas duster. Yep, they’re actually called gas dusters. Check it out at that link if you have some extra time.
So, it comes down to 2 things
2 things, that is, to help keep your laptop cool:
- Use an under-laptop cooling unit, either fan or non-fan based
- Use a gas duster to clean out your machine and allow for better air flow
- Turn up the air conditioning (gratuitous 3rd unnecessary item)
Yep.

It also helps to put a thawing or defrosting tray (for quickly thawing frozen meat) underneath the laptop. The aluminum plate has fins and acts like a heat sink. Combine that with a fan underneath and your laptop barely gets warm.

Concerning the fan, I got a throwaway desktop fan from a computer repairman, cut a hole in the corner of my desk with doorknob hole cutter, and mounted the fan underneath the desk. Then I took the USB connector from an extra cable and attached it to the fan. It is underpowered with the five volts from the USB port, but it doesn’t need to run fast, especially with the addition of the aluminum plate. The fan is completely silent at low speed and should last longer than I do.

PS: Having the laptop at the corner of the desk means that I use an external monitor, mouse and keyboard. In short, I treat it more like a desktop computer which can become portable when necessary.

When I take the laptop somewhere, of course the aluminum plate goes with. By the way, to insure maximum contact between laptop bottom and aluminum plate, I removed the feet (little rubber stick-on strips) from the laptop. That way, the plate works pretty well to keep the laptop cool, even without the fan.

I have a Dell Inspiron 5160 and it runs really hot. How would I go about using a thawing tray and a fan to cool it? Would it be bad to take the rubber feet off the bottom and set it on the tray? Because I’m not sure if that might make the fan intake on the bottom of my laptop stop up and get even hotter. Let me know what you think

I would think you’d want to leave the feet on the bottom of the laptop. they will keep the laptop up off the surface a little more to allow better airflow
