MXM heatsink and what screws to install with

HP Recommended
Touchsmart 520-1050
Microsoft Windows 10 (64-bit)

Hello everyone, I've had this AIO for 8 years now and I've decided to give it a little bit of an upgrade. Swapped out the cpu, brought the ram to 8 gigs, and even bought an MXM that matches the specifications on the support page (3.0 Type A, 35W TDP, etc.)


I've run into a roadblock though. I don't quite know what size those two screws would be to lock the MXM card in place, and on top of that, I can't seem to find the MXM heatsink out there. I know it exists, I've seen it in this video (


I know that video is for the Envy model and everything, but the dimensions all look similar to the internals of my 520: same mobo, same cpu heatsink, the emi cover seems the right size too.


I'd take whatever help you all have. Thank you very much.
