My experience with the problem which obviously is one of the several engineering design shortcomings of the model which aimed high but unforunately hit low. (Other engineering mistakes (apart from bad thermal management (active and passive) which breaks the fan prematurely are insufficient rigidity (when using the laptop!!! on your lap, resting both arms on the panel klicks the right mouse button from beneath!!!) and useless WiFi) is the following:
The helicopter noise which renders the notebook unusable came after several weeks of making some (tolerable) noise, so it was no great surprise, nevertheless it was on a trip away from facilities and other computers that I could use. So I took the thing apart, following the instructions in the video and lubricated the fan bearing (axis) with wd-40 and sewing machine oil.
The effect didn't start immediately. It took the fan more than an hour of operation to "react" (which under the circumstances was several days since it was too loud to work with and I thought the experiment had failed). But then suddenly the fan run as silently as NEVER before. Not even when it was brand new. The fan noise was always a problem with this computer, now it ceased to be. Moreover, this has been 3 months ago and the fan is still running in stealth mode (the computer is used daily for a couple of hours). I have ordered a replacement fan for the time it will start to rattle again, should it start again, but from what I see it might be another three or even 12 months. So yes, I vote SOLVED! (At least buys you a long time to order a new fan).
The reason I am writing this is: if the solution does not work immediately, give it some time (leave it on and go out of the room, after an hour, maybe more, maybe less, it should stop. I lost days that I could not do any useful work on the trip for not knowing that.
