Is there any way to fix a stripped screw hole in GPU PCB?
I'm trying to tighten the heatsink but one of the screws just keeps turning.

get a smaller screwdriver, one that actually fits
or get a screwdriver that strips the screw and makes a new head, fucking your shit up even worse
>>54517891
Yeah. With a hammer.
Get an appropriately sized tap.

I think you misunderstand. The actual screwn and screw head are fine, the part in the actual pcb though seems messed up, the twisting pathway for the screw. I don't know how else to call it.
English is not my native language.

Something like this maybe?
>>54517947
I see. get a bolt for the other side.

Chase the threads with the appropriate size and pitch tap.Heli-coil may work too,provided the hole is deep enough.Last resort? Try two part epoxy.

or a nut, sorry.

Pretty sure this is conductive.You want to be extremely careful and not slop this on a trace.It would certainly work though.
Put a piece of toothpick into the hole. The wood is soft enough to Co form to what's left of the hole and provides pressure to push the screw against the threads.
Hope it helps OP

so, the thread on the cooler screw hole is fucked up? either put a new larger screw in it and see if it sets ok (forced tap) or get a new cooler

I took a picture. Hope it helps you help me.

yup cooler screw hole thread fked up
you could buy a slightly wider self-tapping screw
or you can buy a new cooler
or you can just jam a slightly wider screw you have around you in there and force fit it (might make it way worse or might stay in place)

???
>>54518185
Don't fuck around, just use a self tapping screw or drill it out.
>>54518312
Sorry man, I thougt it said stripped screw, not screw hole.
>>54518299
That's for a seized screw, not a stripped screw. Anyway I think in OP's case the screw isn't stuck.

Can you take the whole heatsink off and take a picture of it without the PCB there, doing anything which is probably going to cause metal filings around a PCB is generally a bad idea, also I/we can see if there's something better to be done.

I bootlegged it by adding a tiny piece of metal wire with plastic around it (the ones you use at grocery stores to tie a bag). Screw screwed in fine but I had to apply a lot of force.
I'll update in a few minutes on how the temperatures are.
Could try adding some threadlocker to your screw. Since it isn't a moving part it may be all you need to help it grab and hold. Make sure you get some that tolerates heat.

Re tap it a size bigger and get a bigger screw
shits easy

Temps are mostly the same, -2C at 100% load since I changed the thermal paste. Guess my bootleg worked.

Does the actual pcb heat up that much?
Is there a chance that the little plastic thing I added might melt and cause damage?
