Would this melt into my PC if I tried to glue it down?

Everything is a little frustrating that it fell loose. However, I fear that if I attach it via the small opening at the end, the computer will heat up to the point where the glue magically melts back into a liquid and spills all over my machine.

Tape it for safety. or seal it

Yes, I gave this some thinking, but I think it will look really tacky then, so I might as well just leave it.

Perhaps some glue tack or something like, provided it isn’t handled too roughly? Perhaps using double-sided tape?

Is that a Dell 7559?

roughly eight years old?

It can be glued. My wifi antennas are taped to the outside of my screen lid. originating from the heat sinks.

It’s a 2017 Dell Inspiron 5577. Although it may seem outdated, it functions well for all I need and all of my games. 16GB RAM, i7 (7th generation, hehe, so it’s ancient), GTX 1080. However, thank you I can probably simply glue it.
