Hi ​@alex, welcome on board! It’s not currently possible, but I think the idea may have been floated around. 

It’d be good if you could add that as a feature request in the Launchpad, to help the team gauge how popular that option would be  If it gets some upvotes that’d be a good indication.

(To add an feature request, create a new post, and select “Idea” as the post type).

Great question, and thanks for sharing it! Are you working on a project with the Metis PCIe at the moment?

hey, we are very soon going to release an SDK update that will enable automatic fan speed control on the PCIe card. We agree it is unnecessarily noisy :)

Thanks for your patience!
