Disable Processor Boost Mode for Cooler Temps Without FPS Loss 

This setting allows your CPU to temporarily boost its clock speed (commonly known as Turbo Boost) under load. While this sounds good in theory, it comes at the cost of higher power draw, increased heat, and louder fan noise, even when most games don’t benefit from it. 

Why Disable It? 

  • Lowers CPU temps by 10–20°C or more. 
  • Minimal to no FPS loss, often just 1–2 FPS in select games. 
  • Quieter system, especially helpful for laptops. 
  • Improves thermal stability and avoids thermal throttling. 
  • Reduces power usage, ideal for long sessions.

 

How to Show and Disable "Processor Performance Boost Mode" in Windows 

I. Press Win + S, type cmd, right-click on Command Prompt, and select Run as administrator. 

II. Copy, paste, and execute this command: 

reg add "HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7" /v Attributes /t REG_DWORD /d 2 /f 

III. Disable "Processor Performance Boost Mode" 

⚠️ Important Note- The steps below will change settings for your currently active power plan*. If you use a different power plan while gaming (such as High Performance or Balanced), then* first switch to that plan in Power Options*. Then proceed with these step, this ensures you’re changing the settings in the plan you actually use for gaming.* 

Steps to disable: 

  • Click the Start menu and search for and open Edit power plan
  • Click Change advanced power settings
  • In the window that appears, expand Processor power management
  • Find Processor performance boost mode and set it to Disabled on both battery and plugged in. 
  • Click Apply and then OK to save your changes

 

Tip- If you want to turn boost mode back on later, simply return to this setting and change it from Disabled back to Aggressive.
