Bed adhesion is an important factor and hairspray on blue tape, plus a tight calibration, a small brim and low first layer height helps greatly.
Besides bed adhesion you also want to make sure these critical areas in your part are already cooled enough before the next layer is put on.
Make them hollow, minimize the infill and place them in a position where the fan will hit them optimally. Another strategy is printing multiple parts at once during the same print run so the layers have more cooling time.
