A) Most likely is overcharged because it is cooling better than it is supposed to.
B) Is working great, even better than manufacturer's specifications.
C) Most likely has higher than normal airflow because of the higher-than-normal temperature drop.
D) Most likely has low air flow because of the higher-than-normal temperature drop.
