The fan on my laptop's heatsink starts to rattles really loudly at seemingly random, I've opened up the laptop to check for random bits of garbage that might've been causing it, but even after cleaning it it still goes crazy for no reason.

Is there any way to fix this ir should I just buy a new heatsink/fan?
