A laptop, and/or notebook cooler, cooler pad or chill mat is an accessory for laptop computers that helps reduce their operating temperature, which is normally used when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related discomfort. A cooling pad may house active or passive cooling methods and rests beneath the laptop. Active coolers move air or liquid to direct heat away from the laptop quickly, while passive methods may rely on thermally conductive materials or increasing passive airflow.

Active Laptop Coolers
Active coolers use small fans to generate additional airflow around the body of the laptop. This helps convect heat away from the device. The number of laptop cooler fans usually range from 1 to 6. Many cooler pads support the use of a power adapter, though they typically run on power drawn through one of the laptop’s USB ports. Additionally, many cooler pads come with a built-in USB hub, so as not to consume one of the laptop’s often limited number of USB ports.
Some active coolers draw heat from the underside of the computer; others work in the opposite way – by blowing cool air towards the machine. The fan speed is adjusted manually or automatically on certain models and on others stays at a fixed speed.
Poorly designed coolers may use fans which draw more current than allowed by the USB standard. Without correct protection, such devices can cause damage to the USB power supply.
Inside the laptop, the USB power-supply has to output an additional amount of watts for the USB-powered fan, thus generating a small amount of additional heat. This additional heat generation is usually insignificant in relation to the amount of heat a fan moves away from the laptop.
Passive Laptop Coolers
Typically, a conductive cooling pad allows for the cooling of a laptop without using any power. These “pads” are normally filled with an organic salt compound that allows them to absorb the heat from the laptop. They are good for a limited amount of time from around 6–8 hours of cooling. Other designs are simply a pad that elevates the laptop so that the fans in the laptop are allowed greater airflow.
The conductive cooling pads are not advisable for laptops that have fan vents built into the bottom as the cooling pad blocks the vents leading to overheating or premature system failure. The best way to determine if a cooling pad would be suitable for a particular laptop would be to take a look at the bottom of the laptop and look for air vents or fan vents. If they are on the side and not on the bottom, it is usually safe to use the cooler pad; otherwise, it may not be safe to use a conductive cooler pad.
The other variety that can be used simply has a hard resting surface that provides a gap between the cooler and the laptop is normally safer to use.
Multi-surface Laptop Coolers
A type of passive cooler that allows both airflow between the laptop base and cooler, as well as, between the base of the cooler and the users’s lap. These laptop coolers are well suited to laptops that have vents on its base because it prevents these vents from being blocked regardless of what ever surface the laptop is used on. Therefore, these multi-surface coolers are suitable for use on desk, lap and uneven/soft surfaces (couch, bed/duvet, carpet) and outdoors.
Multipurpose Laptop Coolers
Recent advancements have brought forward coolers that are multipurpose. Features include card readers for various forms of media such as key drives, memory cards, and 2.5″ laptop hard disk drives. In addition to the above coolers that are a combination of mini work desk with fans are a convenient addition to users that want to use the laptop on a bed or a couch – although they tend to be too heavy and bulky to be carried conveniently everywhere, limiting mobility.
One variant is a cooler with writing pad having an area meant to be used for placing a book or a writing pad – designed with students in mind, although the bigger size limits its mobility and the weight usually results in tired legs for the user when used for a prolonged period of time. A recent addition to the above is an attachable laptop cooler and a comfort pad built into one.

I have been using my laptop two or even three times more than I had ever had during any period of my life in the past. This is good because I have progressed and learned so much.
But I must also pay attention to how hot my laptop gets. I think my best choice is to purchase a multipurpose laptop cooler.
Thanks for suggesting this solution.

This is an amazing review you have here about Laptop Cooling Devices.
These products are super amazing, my favorite among them is the Multipurpose Laptop Coolers; It will be best for the PCs in my office as they work 10 hours non stop.
Thanks for sharing this with me, I will inform my boss about this device.
Thank you so much for your interest in this product. You can share this information with everyone you would like to, as well as your boss.
Thank you again for your support,
Many Blessings and Peace unto You!
This is awesome!
One of the biggest problems I have had with laptops is the extreme amount of heat they can produce.
When I am either watching a video or working for a while on mine, and I hear the fans kick in, I’m always nervous about the laptop crashing because of overheating.
This is a really simple solution to that problem and one that I have never heard of before.
Thanks for bringing it to my attention!
Thank you for committing a portion of your time to read, comment, and considering this post to be really informative information on Laptop Cooling Devices.
I really appreciate your remarks and it definitely pleases me to learn that this is considered new information to you. I have personally experienced laptop crashing because of overheating, losing valuable, unsaved work, what a terrible feeling.
I ended up purchasing the three fan cooling device. I am glad that you have the knowledge about this information, and this shows me that progress is being made in the spreading of this information.
Blessings and Cheers To You My Friend!
I sure can tell you have been building a website or websites for some time.
It really looks amazing that one could land on and get some great information about “the active, passive, and multi-surface laptop coolers.
I’ve tried the bottom coolers that didn’t seem to work too well so I just upgraded and purchased a better laptop that has the cooling vents coming from the sides, it works really well especially if your hand needs warming.
I noticed that you talk about the things in the Bible which I like a lot since I teach the Word of God as well!
I put a blog post up when I first started in WA and I didn’t know that was against the community rules so I removed it because I was getting some slack from some.
Anyways my friend, Great website and I know you will be blessed!
Much more Success,

Hello CJ “Super Cycled” Allen,
Yes I have. I has been around three years up to this point. It really amazes me when I look back and see how far I have come with my websites, podcast, and YouTube channel.
I think serving GOD is what interest me the most out of anything that I do.
Active, passive, and multi-surface laptop coolers are a great addition to any laptop though. They are accessories that really work.
Thank you for your time, the Great website accolade, and the blessed wishes.
Much more Success and Blessings To You As Well,
Oh wow, I didn’t even know cooling pads and multipurpose laptop coolers even existed!
I thought you either get the slide on ones or you replace the eternal fan. This is great information, especially with the world going more digital.
I’m going to have to pick up that multi purpose one with the attachment for the book, that sounds neat!
Thanks for stopping by. I am pleased to be of assistance.
Blessings My Friend,
