I have had this unit since shortly after they were released. Up to now it has worked perfectly. The Board version is H90766-402 I am on the latest BIOS - KYSKLi70.86A.0051.2018.0110.1800. OS is Windows 10 Pro.
SN is BTKY619000RS Manufactured July, 2016
Recently the fan has started making a winning noise that I haven't heard before. I opened the system, and there was minor dust on the fan blades. I used a vacuum cleaner close to the fan to spin it up, and remove dust, and also any dust in the air intake passages. Reassembled, and it is still noisy - almost sounds like bearing failure.
Is there a way to get a replacement, and then send this one back? I would hate to be without it for weeks.
