Weird Crackling Noise after PC start up

FeXate

Greetings, i had to repaste my new Nitro 5 notebook,BUT after turning it on, even tho i managed to do everything succesfully, i hear some kind of sound, i am not super sure what is it exactly, but its coming from the center of the laptop, kinda close to GPU.

Its not loud, i mean, i can hear it once its really super calm and fans are turned off... after i turn them on even slightly.. i cant hear the sound, but i know its there.. do i have to be scared ? dont want to get my PC destroyed month after buying it, and yes, i went to many many authorized acer services where they told me that they are after-warranty.. so i simply had to do it alone, i used Conductonaut cuz its the best for cooling...
 
Any ideas of what i can be ?

It is impossible to answer your question with any certainty except to say that there should be no weird sounds. I would go back through the teardown process and then reassemble it, if that doesn't solve the problem then I would take it to a PC repair shop and have them look at it
