Shut up Surface Pro 7 fan noise!

less than 1 minute read

I recently bought a Surface Pro 7 with an Intel Core i7 and 256 GB SSD and it was a quite good deal. I’m using it primarily for my studies in computer sciences which involves lots of development with Java, Python, C, Linux and so on. Furthermore, I’m using it to write blog posts for this blog.

One thing which annoyed me since day 1 was the fan going absolutely crazy when plugged to AC power. Having only OneNote open and a couple of browser tabs and maybe teams the noise was way too loud and even heard by other participants in meetings.

On Reddit I found a hint to a setting which indeed solved my solution.

We need to adjust the “max. processor power state” setting which is not visible by default on surface devices. To show the setting add this reg key with PowerShell:

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\bc5038f7-23e0-4960-96da-33abaf5935ec" -Name Attributes -Value 2

Afterwards, we can change the “max. processor power state” setting within the power settings in the control panel:

Power settings

Hope this helps you as well to enjoy your Surface Pro 7 with a much quieter fan. 🐱‍💻
