The Arctic Liquid Freezer III 360 is the objective winner of this comparison, securing two out of three total spec victories. 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-performance hardware that generates substantial heat. By outperforming the DeepCool AK400 in the majority of measured categories, it establishes itself as the more capable cooling solution for demanding system configurations.

Users prioritizing maximum thermal headroom should select the Arctic Liquid Freezer III 360 to ensure their components remain adequately cooled under heavy loads. Conversely, those focused on budget efficiency should choose the DeepCool AK400, which offers an MSRP that is 70% better than its competitor. This makes the latter a more cost-effective option for builds where the highest possible TDP rating is not the primary requirement for the user.
