I’ve tried replacing the fans but the problem is still there, it sounds like a fan rubbing and it gets worse if the laptop gets flexed in some way.
I took it apart to look for the issue, but I can’t see anything, when it is open and upside down it runs quiet, unless you press certain places to make it flex around the fan, which is not unexpected. But I can’t see anything out of place or see what can be fixed.
The laptop is a Dell XPS 15
The problem with finding where and how to make adjustments is I can’t work out the physics/engineering of what is causing it, or what the original design was meant to be like. But the other comment does sound useful in this way
