what is the system cooling policy on windows and how do you set it


Howdy, readers! I’m here to guide you through the ins and outs of system cooling policy on Windows. Whether you’re facing overheating issues or simply want to optimize your PC’s performance, understanding this policy is crucial. So, let’s dive in and learn how to keep your Windows machine running cool and efficiently.

Understanding System Cooling Policy

Active vs. Passive Cooling

Windows offers two main cooling methods: active and passive. Active cooling involves using fans or liquid cooling systems to actively remove heat from components. Passive cooling, on the other hand, relies on heat sinks and heat pipes to dissipate heat without the need for fans.

System Cooling Policies

Windows features multiple system cooling policies that determine how the system responds to changing temperatures. These policies include:

  • Passive: The system primarily relies on passive cooling mechanisms, with fans only activating when temperatures reach a predefined threshold.
  • Active: Fans are actively used to maintain a specific temperature range, regardless of the load on the system.
  • Optimal: Windows dynamically adjusts the cooling policy based on the system load and temperature, aiming to balance performance and energy efficiency.

Configuring System Cooling Policy

Accessing Cooling Policy Settings

To configure the system cooling policy, follow these steps:

  1. Open the "Control Panel."
  2. Choose "Hardware and Sound."
  3. Select "Power Options."
  4. Click on "Change plan settings" for your active power plan.
  5. In the "Advanced settings" tab, expand the "Processor power management" section.

Setting Cooling Policy

Under "Processor power management," you’ll find the "Cooling policy" drop-down menu. Here, you can select one of the following policies:

  • Passive: Focuses on reducing fan noise and energy consumption.
  • Active: Prioritizes performance by keeping the system cool even under high loads.
  • Optimal: Balances performance and energy efficiency based on system load.

Cooling Policy Customization

Creating Custom Cooling Policies

Windows allows you to create custom cooling policies to meet specific needs. To do this, select "Create a custom plan" in the "Power Options" window. Then, configure the settings in the "Processor power management" section as desired.

Monitoring System Temperature

It’s crucial to monitor your system temperature to ensure it stays within safe limits. Use tools like HWMonitor or Core Temp to track temperatures in real-time. If you notice high temperatures, consider adjusting your cooling policy or upgrading your cooling system.

Table: System Cooling Policy Options

Cooling Policy Description Pros Cons
Passive Relies on passive cooling mechanisms and activates fans only when needed Reduced noise, lower energy consumption May not be sufficient for high-load scenarios
Active Uses fans to maintain a specific temperature range Optimal performance under all loads Higher noise levels, increased energy consumption
Optimal Dynamically adjusts cooling based on load and temperature Balances performance and energy efficiency May not provide maximum performance in all scenarios
Custom Allows for granular customization of cooling settings Tailored to specific needs Requires understanding of temperature monitoring and system behavior


Understanding and configuring the system cooling policy on Windows is essential for maintaining optimal performance and preventing overheating. By choosing the right policy and monitoring temperatures, you can ensure your PC runs smoothly and efficiently.

FAQ about Windows System Cooling Policy

What is the System Cooling Policy?

A system cooling policy is a set of rules that the Windows operating system follows to manage the temperature of the computer’s components, such as the CPU and GPU.

How do I set the System Cooling Policy?

To set the system cooling policy, follow these steps:

  1. Open the Control Panel.
  2. Click on "System and Security".
  3. Click on "Power Options".
  4. Click on "Change plan settings" next to the current power plan.
  5. Click on "Change advanced power settings".
  6. Expand the "Processor power management" option.
  7. Expand the "System cooling policy" option.
  8. Select the desired cooling policy from the drop-down menu.

What are the different System Cooling Policy options?

The available System Cooling Policy options are:

  • Active: The system will actively cool the computer’s components to maintain a specific temperature target.
  • Passive: The system will only cool the computer’s components when the temperature reaches a certain threshold.
  • On: The system will always cool the computer’s components, regardless of the temperature.
  • Off: The system will not cool the computer’s components, even if the temperature reaches a high level.

Which System Cooling Policy should I use?

The best System Cooling Policy to use depends on the specific computer and its usage patterns. If the computer is used for intensive tasks, such as gaming or video editing, then an Active cooling policy is recommended. If the computer is used for less intensive tasks, such as browsing the web or checking email, then a Passive cooling policy may be sufficient.

How do I know which System Cooling Policy is currently being used?

To check the current System Cooling Policy, follow these steps:

  1. Open the Command Prompt.
  2. Type the following command:
powercfg -getactivescheme
  1. Press Enter.
  2. The output will show the current active power scheme, as well as the System Cooling Policy that is being used.

What should I do if my computer is overheating?

If your computer is overheating, there are a few things you can do:

  • Check the System Cooling Policy and make sure that it is set to Active.
  • Clean the computer’s fans and heatsinks of dust and debris.
  • Ensure that the computer is properly ventilated.
  • If the problem persists, you may need to contact a qualified technician.

Can I create a custom System Cooling Policy?

Yes, you can create a custom System Cooling Policy using the Group Policy Editor. However, this is not recommended for most users.

How do I disable the System Cooling Policy?

To disable the System Cooling Policy, follow these steps:

  1. Open the Registry Editor.
  2. Navigate to the following key:
  1. Create a new DWORD value named "DisableCoolingPolicy".
  2. Set the value of the DWORD to 1.
  3. Restart the computer.

Do I need to restart my computer after changing the System Cooling Policy?

Yes, you need to restart your computer after changing the System Cooling Policy for the changes to take effect.
