Glue or suction cup might work, yes (though with glue, I’d be scared of damaging something if the glue for example grabs something wrong too).
Also, someone mentioned about the gaps on the sides of socket for fingers to fit that I did not know, so that might work too.
I apparently don’t know the difference between IHS and cooler heatsink, no. Looks like, what I meant was IHS.
It’s not as much dropping, as just letting go of it from slightly above, since again the socket was in the way, and well, nothing was fried or bent from this (at least the PC booted up fine), but yes, it’s not exactly ideal.
And yes, I watched the videos, they did not explain properly, someone actually did, there is a gap in the socket, for your finger to fit in, no one mentioned that, this might be the solution.
