So I got a GL62MVR 7RFX MSI laptop few months ago, and the HDD started with this fan noise few days ago. At first I thought this noise was comming from my fan but it was too noisy, usually my laptop makes no noises when idle, until now.

This sound started after changing the thermal paste of my laptop so I don't know if there is any relation with that. I didnt touch it anything as I was very careful with everything.

I don't know if there is something making my HDD doing that. I already checked other threads about HDD's noises but no one is the same noise, mine sounds like a permanent fan running very loud. Sometimes I hear a continous very very low "piiiiiiii", but I don't know if that's from the hard drive.

Should I be worried about it? At the start everything was perfect but now I'm getting too many problems with this laptop.
