In the meantime here’s a link to a video that shows the teardown of a MSI GS65 laptop. From about 10:00 minutes on in the video the fans can be seen being removed from the motherboard.
@joe_q chances of it being torn down by the iFixit team are slim. Remember that their teams are busy with all kind of projects. Now, this isn’t to say it is not going to happen but chances are slim. Also consider that the devices that are being tore down are purchased by iFixit. Maybe you could purchase a MSI GS65 and send it to them and hopefully one of their great techs would find the time to tear it down. Of course, you can purchase one and do your own teardown and post it so the rest of the community gets to see it. It’ll make you a trendsetter for sure. https://www.ifixit.com/Guide/new
Fixing GS65 fan is relatively easy. Disassemble the laptop and heatsink assembly (very small screws) and pull your fan outward. What you will see is a small metal shaft that comes out of a small magnetic hole. Put a very very small amount of olive oil in the metal flange and reassemble the blade assembly. Try rotating it and do not put much pressure while reassembling it (this is the main trick). Rotate the fan and you are good to go.
