Generally Laptops have two methods of cooling down, one is performed by a Fan and other is from a Heat sink, the goal of these two are to cool down the Central Processing Unit (CPU) and the Graphics Processing Unit (GPU) . The reasons / causes for the Heats up may be the dust accumulation blocking the Air vents as a result the computer might expel the excess heat out this makes a fan to spin faster. Meanwhile the Thermal Paste which is connected through the Heat Sink may get dry overtime due to overheating, this causes the laptop to get / run hot very quickly. There are programs out there such as SpeedFan which will monitor your Laptop Heat level. If you do not take actions to prevent / stop overheating, this will cause some serious damages to your internal components.
In this guide we will discuss How to Cool down Laptop. Solutions / fixes used here will be applicable for all the popular manufacturers such as Hp, Acer, Dell, MSI, Asus, Macbook, Samsung, Toshiba and Lenovo. Let's move to the topic,
1. Adjust the Power Options
Windows comes with 3 Power options as Balanced, Power saver and High Performance. The difference between the three are Balance reduce the CPU speed when needed, Power saver reduces CPU speed all the time, High Performance doesn't reduce the CPU speed at all.Â
Generally Windows is set to Balance Power option which reduces the CPU speed when needed. But manually setting the Power options to Power Saver makes sure that the Processor does not run in maximum speed which ultimately makes the laptop cool.Â
To enable Power Saver,
     1. Press Windows + X key.     2. Select Power Options.
     3. Choose Additional Power Settings below the RelatedÂ
       Settings.
     4. Create a Power Plan.
     5. Select Power Saver.
2. Reduce CPU Usage
When performing high end tasks such as Gaming and watching Watching 4K videos will raise your CPU usage level as a result there will be more Heat built up inside the laptop. So it is always recommended to keep your CPU usage level to 45 to 60 %, it will make sure that the system doesn't become unresponsive.Â
Most at times Anti Virus and other programs will contribute most to the high CPU usage so it is better to End task them using the Task manager.
3. Enable Active Cooling
Windows 10 comes with one of the best known features known as the System Cooling Policy. From the The System Cooling Policy users are free to select the cooling mode in which the computer cools. There are two such modes as Active and Passive. Active mode raises the fan speed before slowing the processor and Passive mode reduces the fan speed before increasing the Processor.Â
While Passive mode may be helpful for Power saving, it is recommended to enable Active mode for the Laptop cooling.
To enable Active mode,
    1. Go to the Start Menu.    2. type '' Control Panel '' and Press Enter.
    3. Choose Power Options.
    4. Change Plan Settings.
    5. Change Additional Power Settings.
    6. Change Settings that are currently unavailable.
    7. Expand Processor Power Management.
    8. Change the System Cooling Setting to Active.
4. Purchase a Cooling Pad
Generally Laptops suck Cool air from the bottom and expel Hot air from the Air Vents. Due to the size and the design, the laptop may not be efficiently provided enough cold air. Meanwhile the inbuilt fan inside the laptop too may not be effective enough in expelling excess heat out like a Desktop Computer.Â
The solution for this required Air flow is by purchasing a Cooling pad. The Cooling pads does a effective job of cooling down your laptop merely by 2 to 3 ℃.
There are two types of Coolers available in the market, Active and Passive Cooler. Active coolers does the job of both sucking and expelling heat while Passive coolers only does the job of absorbing heat, according to your laptop model you have to consider between these two.
5. Place the Laptop on a Flat Surface
Generally the Modern laptops suck Cool Air from the bottom and expel Hot Air from the Air Vents present on the side. If any of the above is blocked it will cause overheating, therefore the surface where the laptop has been placed plays a crucial role in cooling down the laptop.Â
Always make sure to place the Laptop on a Flat surface which provides enough Air flow and do not place the Laptop on Soft surfaces such as Bed, Pillow, Sofa and the Lap.
6. Ensure Cool Surroundings
Hot Surrounding may be one of the possible reasons for a Overheating laptop. Laptops has to be placed on Cool surroundings for it to function efficiently, if the surroundings are more hot then the fan has to do the work to remove the additional heat.Â
Do not place your Laptop on a place where it get direct sunlight such as near a window and always make sure to place it in the shade. Most ideal places for a Laptop are an Air Conditioned room.
7. Clean the Fan and the Air Vents
Overtime dust and other particles might have blocked the fan and the air vents, this makes the laptop not to get enough Air flow. You can check this by placing your hands near the Air vents, if you feel Hot air is blowing out then the fan does the function if you do not feel anything then something has clogged inside.Â
So the simple way to solve this is by cleaning the fan and the air vents. Carefully remove the battery and the back cover and clean the Fan and the Air vents with a Cotton cloth or with a Air Compressor. If you are unsure of removing the Laptop components you can get a Professional's help.
8. Shutdown the Laptop
Shutting down the Laptop may be the last option you may try after trying out the above methods. Sometimes prolonged usage of the system makes programs to take too much resources from the system. So by simply restarting it may give the laptop a rest and provide a temporary solution.
