The verdict
The phrase is ambiguous: PC searches compare CPU cooling methods, while this air-cooler category covers rooms. Noctua NH-U12S redux and Cooler Master Hyper 212 3DHP Black ARGB are CPU coolers, not room appliances. If you meant home cooling, compare evaporative coolers with air conditioning instead.
Dry, ventilated conditions: Noctua NH-U12S redux
Evaporative cooling can suit dry air with fresh-air exchange.
Cooling in humid conditions: Cooler Master Hyper 212 3DHP Black ARGB
Refrigeration does not add moisture to room air.

Common questions
Questions before you buy
Which is better, air cooler or liquid cooler?
For a CPU, it depends on heat load, case clearance, noise and maintenance. A room air cooler is a separate product category.
Does a 120mm liquid cooler beat an air cooler?
Radiator size alone does not decide results. Compare independent testing for the exact CPU and cooler, plus case fit and noise.
Can a CPU liquid cooler cool a room?
No. It moves heat from a processor to surrounding air; it is not room air conditioning.
What does air cooler mean in this search?
It can mean a CPU heatsink or an evaporative room unit. Check surrounding terms before comparing models.
