thermal paste i need help with gpu thermal paste

[georgian boy]

hello, recently i changed thermal paste on my gpu, i had problem mounting screw, i wiggle it little bit but i didn't take it off (I didn’t put much pressure either) than i Thoth it would be good to check and i remove heatsink for a second, paste looked like volcano on bottom and On the head as well, it was not spilled over from main square, i don't know what to do, my pc was already dead when i did that and i cant test temperatures, tell me what you think please.

so i changed thermal paste on my gpu first time. i had problem with mounting  heatsink, finally i did it but before i tightened screws i remove them, remove heatsink and check thermal paste (i am dumb) i did it for just second  i do not think The dust managed to penetrate, before removing i didn't put any pressure on heatsink, paste was not spilled over main square (this square what is on the photo) it looked like a volcano, i am worried now and don't know what to do.

p.s. i tightened screws until i can't more, maybe i over tightened them but they had little springs on them and i think they don't allow me to overtighten it
