The stock fan in the 7*** series and I believe also in the 8*** series has a feature that automatically increases the speed of the fan as the internal temperature rises and subsequently lowers the speed as the temperature falls again. That could explain why the fan appears to be labouring on warmer days. If the processor temperature is 27 C, I would consider that excellent and wouldn't be concerned about overheating.
