Hi everyone! I recently noticed this strange noise coming from my Anycubic Kobra 2 Neo when I turn it on or when the printer starts heating up.

The noise seems to be coming from the lower part of the printer, possibly from the power supply or one of the fans. What is interesting is that after the printer has been running for a while, the noise usually becomes much quieter or disappears.

I recorded a video so you can hear the noise.

Has anyone experienced something similar with their Kobra 2 Neo?

I would especially like to know:

• How can I properly diagnose which component is causing the noise?
• Could it be the PSU fan, motherboard fan, or another fan?
• Is this a common issue with this printer?
• If the fan needs to be replaced, what replacement fan/brand would you recommend?
• Are there any specific voltage, size, or airflow specifications I should look for?

I would appreciate any advice or recommendations before I open the printer or replace any components.

Thank you!
