I can buy that, but, anecdotally, my machine is noticeably warmer when I'm under Windows [0], and it does blow its fan too, just like my colleagues'.

So, I don't think it's just a question of fan profiles. Plus, on Linux, I can't control the fan. I can't even read its speed. On Windows, they have all the "recommended" HP crap, but it's true that I didn't fiddle with those, and I doubt my colleagues did, either.

[0] I do use Windows rarely, but when I do, it's for fairly long stretches (multiple days on end) so it has the time to do its scanning, updating and whatever elsing.
