There is no leak detected & the thermostat seems like a likely component to suspect (or simply replace, since it's relatively inexpensive, not hard to get to & could be 10 years/164K old).
2. I checked RockAuto out of curiosity this morning & they have the following array of fans that are substantially less costly than the BEHR....Are these fans fraught with danger?
(I know someone already mentioned steer clear of Dorman)
TYC 611400 $156.79 ( I noticed Bavarian Auto also sells this..but for $219)
DORMAN 621213 $175.79
FOUR SEASONS 76164 $298.79
VDO FA70744 (no price...out of stock)
(and I suppose I should ask the same of the thermostats at RA, but those choices seem to be the same array as the common BMW vendors.
thanks again for the feedback.

You should have a mechanical fan attached to the water pump, in addition to the aux fan. Unless the mechanical fan is also faulty, your X shouldn't be over heating with the AC off.
A scan of the X with BMW Scanner 1.4 or any BMW specific scanner will indicate the fan fault and a bad thermostat.
I wouldn't be driving the BMW until you get the overheating issue under controlled or else you risk warping the head which will be an even more expensive fix.
If people just wants to drive a cheap car why do they buy a BMW and use cheap parts on it?
