So I decided to make my own lightweight application with the OpenHardwareMonitorLib API, and here is what I got so far. The existing UI is a HWMonitor clone that allows to set a manual fan speed to any fan, but no temperature/speed fan curve here. OpenHardwareMonitor is divided into two parts, an API to interact with your hardware ( CPU, RAM, Fans. However, thanks to the code base being open sourced, there are a couple of active branches, LibreHardwareMonitor being the best one I found, supporting my MSI Z390 Edge AC board and being updated regularly. The first link is an original project which could be downloaded here , but just like SpeedFan, the project is not updated anymore. I searched around for an alternative software with this particular feature and only found a paid option (Angus Monitor). (My BIOS only supports CPU temperature as a temperature source for the PWM fans). I used it to bind my case fans speed to the hottest component of my PC, my GPU. The main feature I used was the custom fan curves with custom temperature sources.

I built a new custom UI on top of OpenHardwareMonitor with additional features, mainly linear fan curves with custom temperature sources.Īs you guys may know, SpeedFan is sadly not updated anymore, so newer boards are not detected properly.
