The reason I say is that they may have been a pre production run to get them out early for reviews.Wouldn't really make any difference if they were or not. Intel know sites do teardowns on cards and they know all about first impressions. Using tape really made the build quality seem cheap and wasn't a good look especially for their first proper gpu. It's been brought up a few times by GN since so presumably it was also in retail cards. Didn't seem to be a factor in third party card with their own coolers design though.
