[Plugin] FanControl.CurveReader - Temperature and PWM logger

[JesusRomero77]

Hi everyone,

I'd like to share FanControl.CurveReader, a plugin that logs temperatures and PWM values from FanControl to a file, so you can analyze how your fan curves behave under load (gaming, rendering, etc.).

What it does

• Logs the temperature of the sensors and the PWM of the controls you select in FanControl.
• Writes to the log only when a value changes, so the file stays small. The log size is capped at 100 MB and old entries are purged automatically.
• Each profile gets a summary at the start with all its controls, curves and sensors, and profile changes are detected and logged.
• Per-element settings: include it or not in the log, minimum interval between entries (1-3600 s) and change threshold (1-10).

Configurator app
It comes with a small portable app (CurveReaderConfigurator, Windows Forms, .NET Framework 4.8) to choose what gets logged and with which interval and threshold, without editing files by hand. English and Spanish are supported.

Things to know

• Like any FanControl plugin, it only runs while the FanControl interface is open (that's when FanControl loads plugins and the app takes over fan control from the service).
• Built for the .NET Framework 4.8 version of FanControl. I tested it with FanControl 282.

Download and source code
https://github.com/JesusRomero77/FanControl.CurveReader/tree/Release
Latest version: v2.2 (plugin DLL + configurator in the same release).

It's a very recent project and I think I'm the only user so far, so feedback, bug reports and suggestions are very welcome (please use the issues of my repository for them).

Planned for the next version
The profile summary written in the log is currently in Spanish (PERFIL ACTIVO = ACTIVE PROFILE, and others etc). The log is written in the log is currently in English. I'm planning to make it follow the language selected in the configurator (English/Spanish), so the log messages match the language of the app.

@Rem0o if you find it useful, feel free to add it to the community plugins list in the README. Thanks!

UPDATE: Log language now available in v2.2, see this comment.

Language support is now available in version 2.2! You can pick your language in the configurator app, and the log follows it. Download it from the v2.2 release. Let me know if you find any missing or incorrect translations.

It’s very easy to add a new language in the code: in Language.cs, copy an existing language class, paste it, and change the values. Do it in both projects (the plugin and the configurator), using the same Name in both, and then recompile. That’s it. Or, if you prefer, just send me the translation and I’ll include it in a new release.
