AI Versus Verdict
The Thermalright Peerless Assassin 120 SE is the objective winner of this comparison, securing two out of three spec victories. Its most significant advantage is a 41% higher TDP rating compared to the Noctua NH-U12S Redux. While the Noctua NH-U12S Redux maintains a slight edge in acoustics, offering a 2% improvement in noise level, the Thermalright Peerless Assassin 120 SE provides substantially greater thermal capacity for handling heat-intensive workloads.
Users prioritizing maximum thermal dissipation should choose the Thermalright Peerless Assassin 120 SE for its superior TDP rating. Conversely, those who place a premium on quiet operation should select the Noctua NH-U12S Redux, as it offers a quieter noise level. Your final decision should depend on whether your primary requirement is the higher cooling potential of the Thermalright option or the marginal acoustic benefit provided by the Noctua alternative.
