Rainmeter CPU Temp Code: Understanding the Differences in Windows 11

When it comes to monitoring CPU usage and temperature with Rainmeter, users often rely on its ability to provide accurate information. However, some have reported discrepancies between Rainmeter's readings and those from other tools like Task Manager or Gadgets. In this article, we'll dive into what might be causing these differences and explore the reasons behind them.

Firstly, it's essential to understand that all usage info provided by Rainmeter comes directly from Windows itself. This means that any inaccuracies in its readings are likely due to issues with Windows' thread scheduler or other system components. Microsoft has made changes to this scheduler for newer hybrid CPUs (p-cores vs. e-cores), which might be contributing to the differences between Windows 11 versions.

One user reported that Rainformer, a popular Rainmeter skin, worked perfectly on Windows 11 version 21H2 but stopped working accurately on version 22H2. In contrast, Gadgets' CPU meter continued to provide accurate readings on both versions. When comparing screenshots of Rainformer and Task Manager with the top CPU rainmeter from Gadgets on Windows 11 22H2, it's clear that Gadgets' CPU-meter is providing more accurate information.

It's worth noting that Rainformer's top CPU rainmeter shows incorrect CPU usage for processes, while Gadgets' version appears to be more accurate. The exact same symptoms can be seen in the Rainformer and Task Manager readings on Windows 11 22H2, where only a few processes are displayed at a time.

In conclusion, the differences between Rainmeter's CPU temp code and other tools like Task Manager or Gadgets may be due to changes made by Microsoft for newer hybrid CPUs. While Rainmeter relies on Windows' thread scheduler for its readings, Gadgets appears to be more accurate in its CPU-meter display. If you're experiencing issues with Rainformer or other Rainmeter skins, try checking the version of Windows you're running and exploring alternative tools like Gadgets for a more reliable view of your system's CPU usage and temperature.
