Thermalright Assassin X 120 (Single-Tower Air/4 Heatpipes/120mm PWM Fan/155mm Height/Extreme Budget Value) Review
Thermalright Assassin X 120 budget single-tower air cooler, 4 heatpipes, 120mm PWM fan, 155mm height, AM4/AM5/LGA1700 support, 180W TDP, extreme value pricing.
Thermalright built its reputation on selling far more heatsink than the price tag suggests, and the Assassin X 120 continues that at the entry tier — four heatpipes and a single PWM fan for well under the cost of a name-brand equivalent, aimed at builders who'd rather spend the savings on a GPU.
Comparison to Alternatives
It's the little sibling to the Peerless Assassin 140 in this catalog: the same value-first philosophy scaled down to a single-tower, single-fan format for tighter budgets and smaller cases. Against the Cooler Master Hyper 212 Black Edition, the Assassin X 120 typically undercuts it on price while landing in a similar thermal band.
