Adhesive to secure fan piece to logic board

I opened up my laptop after hearing a buzzing coming from the right fan at high speeds. It looks like the nut(?) that connects the top screw on the right fan (top right on left fan, when opened up) had become disconnected from the logic board.

What do I need to do to reconnect this piece? Photo shows just how large a gap there is when it’s removed, so I assume I need to reattach it to the logic board. Is there a special adhesive or solder I need to use?

@finch1 - The pics appear to show the mounting stud on the logic board has been snapped off! This 'nut' needs to be remounted to the logic board so the fans mount screw can be secured to it.

Can you take the fan fully off and then take a nice clear pic of the mount area on the logic board, as well as the mating side of the stud if you still have it.

@danj Updated post with plenty more pictures! Thanks for letting me know the name of the piece too :)

@finch1 - Rachel you’ll need to clean the mating surfaces with a some acetone (reagent quality) to make sure the old Cyanoacrylate glue that was used to hold the stud is removed. Make sure the surfaces are smooth any unevenness will prevent good adhesion.

You might find the stud will fit better in one position rotate it around until its at the best placement make a mark with a fine point marker to index the placement.

Here’s a good reference on Cyanoacrylate glues

I would use a gel type and while it is weird you want to breathe onto the area! The moisture in your breath will speed up the setting.

You’ll want a small but heavy weight to help hold stud in place as the glue sets. While holding it with your finger might make sense on some jobs, I find our bodies move too much which causes glue to fail to set correctly.

So you want to get your setup just right before you start and you want to wear dust-free nitrile gloves so you don’t glue your self ;-}

When you put the screw back in you don’t want to over tighten it as the stud can shear-off again. Just tighten snugly and place a drop of nail polish on the edge for the head of the screw to prevent it from loosening up from the fans vibrations (don’t over do it)

First, disconnect the battery and find the screw!

Sorry, I should have been clearer! The screw is there, I just removed it for the photos to show the loose piece. The nut(?) that connects to the logic board is loose. So the screw can screw into the nut, but that part isn't connected to the logic board.

The first photo shows the nut, and how it isn't adhered.
