[SOLVED] Aorus Master x570 Chipset Heat Issue - after 20H2 Windows Update - FIX NEEDED


Nov 24, 2015

Recently I updated Windows to 20h2 and since then I'm facing Chipset temperature spikes.

Every Windows app including Start Menu and Search instantly gives 10-15 celsius degrees spikes. The chipset on Idle is 38°.
Components are brand new bought a month ago.

I had no issues before the update.

Device Specs:

Device name DESKTOP-EB3MMG1
Processor AMD Ryzen 9 3900XT 12-Core Processor 3.80 GHz
Installed RAM 16.0 GB
Device ID XXXX
Product ID XXXX
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display
Mobo Aorus Master x570

Windows spec:

Edition Windows 10 Pro
Version 20H2
Installed on ‎12/‎29/‎2020
OS build 19042.685
Experience Windows Feature Experience Pack 120.2212.551.0

Once again,
Everything related to APPS including App Settings ETC is giving temp spikes followed by intolerable fan noise.


PowerPlan CPU tuning fixed the issue.

I made a mistake and bought Wraith Prism. Too weak cooler for 3900XT. Too much noise.

Minimum Processor changed from 99% to 15%.
Minimum is OK even with 5%, that's what I do. Drops idle frequency to less than 2000MHz vith less than 1v keeping it very cool.
Maximum CPU set at 99% will get CPU to run at at it's base frequency, no matter what boost and PBO is set to. Less than 99% down to 50% lowers maximum CPU frequency even more.
What I do is to modify 2 power plans, one to 50 and 5% which keeps CPU up to 2200MHz more than enough for day to day mundane work like internet browsing etc. and one PP to 100 and 5% which allows full boost and PBO when needed for some heavy work and gaming.
