Framework Laptop 16 Windows Fan Control Tool
Framework finally released a BIOS with the EC tool that has the ability to control fans. 
I built a lightweight tool that allows you to control fans and create a basic fan curve.
Framework 16 beta BIOS 3.06 is required (BETA) → BIOS
Here’s a link to the actual app: Framework Control
Need to install a lightweight Rust service to be able to use it. Link provided in the APP
All code belongs to me and is open. If paranoid, you can build the service from source (steps in the repo)
@Lupin and anyone else who needs a tool to be able to control fans on FW 16 on Windows. Might work for other Framework laptops, not tested.
