Fan is struggling and whirring, do I need to replace it or is this somehow not a motor issue?

Model: Lenovo Legion Pro 5 9th gen

I have no clue how to open it up and check it without fucking it up bad, but I don’t think it should be dirty as I’ve had this for approximately 4 months

Contact Lenovo for warranty

I still have warranty, I’m guessing the motor needs replacing?

You said you’re not willing to open it up, so you’ll need to let Lenovo decide that
