Fan making odd noise sometimes
Hello, so recently I've started running into an issue with my laptop fan. The fan will sometimes start being really loud/start making an odd noise (noticed this tends to happen when I put something onto the table with a bit more force or when I put down my headset onto the laptop keyboard). I've not had this issue before like a week or so back and I'm not sure what could be causing this and how this could be solved (will pin a video of the fan noise).
*Not sure how relevant this info is but I've recently (about a month back) upgraded the CPU, which of course involved taking the fan out and putting it back in. I've checked countless times and there's no screws or anything important missing to my knowledge but mentioning it in case it could be related.
Any kinda help or advice is appreciated in advance!
