The Arctic Liquid Freezer III 360 A-RGB is the objective winner of this comparison, securing two out of three total spec categories. Its most significant advantage is a TDP rating that is 59% better than the alternative. This superior thermal capacity makes it the more robust choice for handling high-heat output components. By outperforming the Thermalright Peerless Assassin 120 in the majority of measured specifications, it establishes itself as the more capable cooling solution for demanding hardware configurations.

Users prioritizing maximum thermal headroom should select the Arctic Liquid Freezer III 360 A-RGB to ensure optimal heat management under heavy loads. Conversely, those focused on budget efficiency should choose the Thermalright Peerless Assassin 120, which offers a 76% advantage in MSRP. This makes the latter an ideal option for builders who want to minimize costs while still securing a functional cooling solution that remains competitive in specific technical areas.
