My last few prints the chamber fan has been extremely loud during the start of prints, and then returns back to normal after around 30 seconds. The printer only had around 100 hours on it so i dont think there is any wear and tear from use. I recently moved and im worried something got bent or came loose and is causing the issues. I have a video but its not an accepted format. If you have advice on what may be going on or how to get to the fan to take a look at it.
I have the same issue, but it comes and goes. I printed a fan grill in case there was debris getting into the fan housing, which seems to have limited the problem
Here’s how to get the back off:
I had one chamber fan die really early but they have started using better fans since then.

With the last two firmware updates and the previous version of the fan hardware itself, this is a known issue.
