The backlight noise is very quiet, and in fact didn't even realize it was happening until someone else mentioned it. So that's not a problem, but the fan noise was obvious from the beginning. Although, maybe if the fan goes quiet, the backlight noise will be more pronounced. Let's hope not.
I'm in the US and ordered it from China, so now I'm on the fence as to whether I should crack it open and fix the fan, probably voiding warranty, or send the thing on a round trip and be without a scope for who-knows-how-long.
Anyway, I've yet to see any thorough reviews of this model, so I'll post what I can about it, provided I don't kill it fixing the fan. If nothing else, photos of the guts if/when I crack it open.
