I had bad experience also with a chip without glue on. I tested around 30+ SKL chips now mixed of i3/i7/i5s
and delidded around 10. All 10 tested cold with the glue on and no problems, non of them died on me. Then
I bought a delidded chip without glue on so I used white bond paper as a spacer, 1st day tested on AIO works
and second day powered up my gene and instant 00
* Looks like removing the glue is bad for our health
