As said the fans don't effect temps on the motorway

Should run around the 85 mark , can't remember off the top if my head if the 306 stat opens at 83 or 86 but the temp shouldn't be any lower than 80.
If it is lower than that it would point to a sensor issue or guage under reading.

Changing the stat isn't a problem, bleeding the system and making sure you have all the air out isn't so easy
