The Arctic Liquid Freezer III Pro 360 A-RGB is the objective winner of this comparison, securing victories in two out of three measured categories. Its most significant advantage is a superior TDP rating, which outperforms the Noctua NH-D15S by 40%. This substantial lead in thermal design power capacity makes the liquid cooler the more capable option for managing high-heat output components compared to the air-cooled alternative.

Users prioritizing maximum thermal headroom should select the Arctic Liquid Freezer III Pro 360 A-RGB for its superior TDP rating. Conversely, those focused on initial acquisition costs should choose the Noctua NH-D15S, which holds a 33% advantage in MSRP. The decision rests on whether the user values the increased cooling capacity of the liquid solution or the lower entry cost offered by the air cooler.
