Jeebus that's one heckuva wall of text. I skimmed:
ca glue
When it comes to the broader "superglue" you mentioned, I've used several that create a bond by melting the surfaces it's applied to. I get it - you were trying to get across "metal good" and "superglue" just gets across easier. But if you knew the horror stories I've seen in the process of helping thousands of newbies troubleshoot hardware issues, you wouldn't be so flippant about your instructions.
Based on the ops own post, the ssd is idling at 67 or so c. We wanna keep it below 90 for [explanation redacted].
the heat is coming from inside the ssd
OP's ssd that should be idling in the 40C range is idling at 67C. Do you think addressing just the ssd temps with a heatsink will solve OP's issue or is there some core problem that needs to be addressed before we even start talking about ssd load temps? With 3 ssd failures so far and unaddressed heat issues in other components reported by OP, how long do you think OP's motherboard, PSU or other components are going to last?
