There is a mechanical grinding noise coming from my bambu x1 carbon and i cant seem to identify it. I have not yet disasembled it to poke around. Bambu X1 Carbon Grinding Noise. - YouTube
Bad MC fan - VERY common problem. Send that video to support and they’ll, eventually, send you a $20 code to buy a replacement from their online store. Many of us have replaced this with a Noctua fan (specifically Noctua NF-A4x10 5V PWM), or you can use a larger fan with holders you can find on Printables.) Some splicing of wires is required.
