After I installed an M.2 NGFF AHCI NVMe SSD M Key Converter Adapter, I put in a Samsung 970 Evo and a SATA Samsung 850 Pro. I noticed that the boot time is slower from my Samsung 970 than my MacBook with a SATA SSD it has in it. Im not sure why that is. After I put the display back on, I noticed after a couple days the screen wasn’t fully on and it was popping out in some areas. I tried 3 adhesive strip sets from iFixit and 1 from OWC all having the same problem. I was wondering if 3M mounting tape would be a good alternative? Another problem I have after the SSD upgrade is my microphone is not working. The cable itself looks broken. Where could I find a microphone replacement for it?

Ouch! You’ll need to open your system up again to replace the adapter as its bad. I really don’t recommend using these adapters in iMac’s as its such a bear to get to them Vs a MacBook Pro. I would recommend going with a OWC Aura Pro X2 SSD. Yes, its more expensive! But how many times do you want to tear into your system? You microphone issue may not be a bad unit! I bet you managed to clog the microphone hole with the tape!
I strongly recommend using the proper tapes designed for the system. I use a single hole paper punch to trim the tape for the needed gap. A common issue is using poor quality solvents to wipe the surface. Then often leave a film which messes up the adhesion, the other issue is not pressing the screen into the case so the adhesive is able to grip firmly. I use a small rubber J roller to help me press the display down. Lastly, temp is a factor too! A room that’s cold will prevent the adhesive to cure effectively! Even in a war room I would use a hair drier or variable heat gun to warm up the surfaces and keep them warm so the adhesion is firm.
