This problem related to this Heatsink making noise (like crackling)

Hi, my problem is identical to the one described in the link above. I even have the exact same laptop. I've been looking for this problem for weeks on the internet, but I've never been able to solve it. Everything is the same, when replacing the thermal paste and pads, I bent part of the heatsink a bit and now with the fan on, it hisses and crackles in games. The problem is definitely not the fan or debris, the sound is coming from the heatsink. What should i do ?

I copied a photo from another thread, it's identical with me where the heatsink was bended and probably where the noise comes from.
