Is the Peerless Assassin Still King? Montech NX600 Tested

Today James reviews the Montech NX600 CPU cooler, a dual tower air cooler positioned in the same budget space as the Thermalright Peerless Assassin. On paper, the NX600 features a dual fin stack design, six heatpipes, and dual 120 mm fans, with support for modern Intel and AMD platforms including AM4, AM5, and LGA1700. As with any air cooler in this class, specifications only tell part of the story. In this review, the Montech NX600 is put through full thermal testing, noise testing, and 40 dB noise normalised benchmarks. The video also covers AMD PBO behaviour, installation on AM5, RAM clearance considerations, fan design, and overall build approach.
