The DeepCool AK400 is the objective winner of this comparison, securing two out of three spec victories. Its most significant advantage is its MSRP, which is 70% better than that of the alternative. While the DeepCool LS720 360mm holds a clear lead in thermal management capabilities, the overall spec-based evaluation favors the efficiency and value proposition offered by the smaller air cooler in the majority of measured categories.

Choose the DeepCool AK400 if you prioritize a lower MSRP and a more compact cooling solution for your build. Conversely, select the DeepCool LS720 360mm if your primary requirement is a higher TDP rating, as it provides a 59% advantage in that specific area. This choice depends entirely on whether you value the cost-effectiveness of the former or the superior thermal capacity of the latter for your system.
