I have just received one myself from Amazon UK, I too also have the FAN issue, however it seems its an EC/BIOS tuning issue as the clicking is related to the fan trying to spin up (AKA not having enough power to spin it up).
However it will then come on at full wack for 5 seconds before going back to click click click.
I have noticed on the site that there is an update for the EC and BIOS question is which way do we flash it, BIOS first then EC or EC first then BIOS. the instructions on the site isn’t clear at all.
