Fix Laptop Thermal Throttling

You all know it is normal for a laptop to produce heat. But when they bring out more heat due to heavy load, it impacts the performance and slows down the PC. Sometimes, overheating could cause permanent damage to components like GPU, CPU, memory modules, and other hardware. The PC has a safety mechanism called thermal throttling for Windows PC to protect it from excessive heat, designed by Microsoft. If you are worried about thermal throttling laptops, read this guide to perform a thermal throttling test and fix laptop thermal throttling.

How to Fix Laptop Thermal Throttling

The CPU has a critical temperature of nearly 80 degrees Celsius. When a Windows PC reaches a high temperature, its performance is reduced to stop excessive heat from piling up and start cooling.

  • Overall, it optimizes the power usage by automatically adjusting the speed of a microprocessor and preventing internal heat and damage to components.
  • It is primarily due to overheating generated by CPU or GPU, whenever it takes a lot of loads and heavy usage, which happens when you play an intensive game, poor airflow, prolonged laptop usage, and overclocking.
  • If you overlook the thermal throttling issue and rectify it, your laptop may get damaged permanently.

Therefore, it is very crucial to check its usage often and resolve it at an earlier stage itself.

Note: The critical temperature varies with respect to the processor’s manufacturer and model.

Preliminary Steps

Below are the basic fixes to prevent thermal throttling.

  • Ensure you do not have dust in the laptop’s internal components as they could block airflow and clog it due to its compact nature and leave no space for adequate cooling, which in turn causes overheating.
  • Try to minimize laptop usage as thermal throttling can happen when the PC is used for a long time with a heavy workload.
  • Decrease the graphic quality settings while playing games.
  • Perform monitoring software checks regularly, which helps to detect laptop thermal throttling.
  • Increasing the clock rate makes the processor work faster than the usual speed, significantly raising the temperature. Try to reduce the clocking speed.
  • A cooling pad or even a chill mat could help you keep the overall temperature of the laptop down. Therefore, place a pad or mat below the laptop and use it.

Always keep the power plan of your laptop as high or best performance mode to prevent thermal throttling issues in the future. This method can fix the thermal throttling problem and be considered a preventive measure.

Method 2: Edit Power Plan Settings

Another way to control thermal throttling is to edit power plans in Windows 10 and change them. Here, you need to keep the minimum and maximum processors to 100. If it is below 100, it impacts the laptop to throttle under high usage. To keep these states as 100, follow the steps given below.

1. Type Control Panel on the Windows search bar and select Open as shown.

Method 3: Modify Registry Editor

Disable thermal throttling via the Registry Editor can be unsafe, and it is possible to lose all the data in your PC. Therefore, ensure to make a backup for the whole laptop. Also, this method will prevent laptop Thermal Throttling. To disable it, follow the steps given below.

1. Press Windows + R keys together and open the Run dialog box.

2. Type regedit in the dialog box as shown and hit Enter key.

Type regedit on the Run dialog box

3. Click Yes in the User Account Control prompt.

4. On the Registry Editor window, navigate to the path:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

5. Locate the Power folder in the left pane and right-click on it.

Navigate to the path and right click the power folder

6. Select New and then click the Key option on the sub-menu as depicted.

Method 4: Use Thermal Paste

Applying thermal paste could be a fix for thermal throttling laptops. All computers have a thermal system that is small which connects the CPU. Due to its compact nature, there is no air between them. Still, some air can get in between those gaps.

  • You are well aware that air is a bad conductor of heat. So, when the CPU heats up, the thermal conductivity decreases due to the air present, which does not allow the CPU’s excess heat outside.
  • Also, it prevents the cooling process of the CPU and thus leads to thermal throttling.
  • Applying the thermal paste to the gap blocks the air and allows the thermal system to cool down with better thermal conductivity.
