Hi Riccardo, I’ve hit this a fair bit too, but it’s usually too late to be clear on the exact cause by the time I hear a fan spin up and spot what’s happened. I was suspecting mine being triggered by the use of keyboard shortcuts in GWorkspace (e.g. creating directory, moving a file to recycler). It seems to happen less when I’m not using GWorkspace keyboard shortcuts so heavily, but I’m not very certain on this!
