The Arctic Liquid Freezer III 360 is the objective winner of this comparison, securing a lead in two out of three measured specifications. Its most significant advantage is a 25% higher TDP rating compared to the DeepCool Assassin IV, indicating superior thermal management capabilities. While the two coolers tied in one category, the Arctic Liquid Freezer III 360 consistently outperformed the DeepCool Assassin IV across the majority of the evaluated technical metrics.

Users prioritizing maximum thermal headroom should choose the Arctic Liquid Freezer III 360, as its higher TDP rating provides a clear advantage for demanding cooling requirements. Conversely, the DeepCool Assassin IV remains a viable option for those who prefer the specific design characteristics that allowed it to tie in the remaining category. Selecting between these two components depends on whether you require the increased thermal capacity of the liquid cooler or the alternative specifications offered by the air cooler.
