@Suban228Ah, same manufacturer month as you for both of them.

I will let you know what Scan says once they assess the return, but looking like that whole batch was f*cked. Hopefully more people looking at purchasing this motherboard can find this thread on search engines.
 

@Mark Kaine Ah yeah, you’re right - sorry, completely missed that.
 
Have just unplugged the AIO completely and then the back fan which is separate… sadly the same noise issue. Also changed the PSU whilst I was at it.
 
It’s definitely the motherboard sadly 😞 Unless I’ve missed something, I’ll give it a few weeks and potentially RMA with Asus. It does seem to only be an issue once booted into Windows, so I shall try USB Linux in a bit.
 
 

I wouldn't touch Gigabyte this generation, really low quality materials and poor performance overall.
