TL;DR: fan scraping noises, fix by flattening “sticker” below where fan sits.
Upon first power up I noticed a sort of scraping noise coming from the right fan. Blowing into each, I could replicate the issue. Went to pull the fan out (only needed the GPU housing removed > four black captive screws loosened > two gold screws taken out on black plastic bar next to the fourth black screw.) Probably should’ve disconnected the wire, but I was careful.
Took the affected fan out, blew on it, and no noise occurred. When I put it back it did the same thing. Took it out again and noticed the black “sticker” (for lack of a better term) below where the fan sits was up just a tiny bit. Pressed it down with the spudger and my finger, put everything back and that fixed the issue.
Additionally, the Interposer lid appears to be brittle on it’s hinges.
While annoying, the experience of just being able to take things apart SO easily like that without a guide (especially with the incredibly satisfying slotting and magnetics everywhere) made me enjoy fixing it.
UPDATE: As the fans spin up and I use the laptop… on my lap, I can hear the noise again. Not as severe, but definitely there. Still noticeable when I set it on a desk. Perhaps the heat made the “sticker” come up? When I looked inside there was barely anything to remark about, but still produces quite an audible sound. Not as much on the other fan, and no unordinary noise from that side either.
Also, the Interposer lid does like to pop off, at least, particularly if one of the hinges is bent. I do wonder with it’s tendency to sometimes flip down while working in there if more users are inclined to push the lid back further.
Now I’m just trying to figure out why I can’t boot into my SSD or a Ventoy USB. Not seeing any secure boot related options in BIOS…
SOLVED: You have to spam F2 before you get any boot errors in order to get into the Administrate Secure Boot options.
