Thermalright has recently launched the Peerless Assassin 120 Mini series of twin fin-stack CPU coolers. This cooler is a smaller version of the Peerless Assassin 120, released in 2021, featuring a more compact heatsink and only one fan.
This cooler features a nickel-plated copper base, with six copper heat pipes (6mm) and two aluminium fin stacks at each end. The Thermalright TL-D12B fan has a fluid dynamic bearing and can reach up to 1,500 RPM, providing up to 66.87 CFM of airflow at 1.53mm H2O static pressure. The noise level of this fan is relatively low, with a maximum noise of 25.6 dBA.
In addition to a smaller heatsink, the design of this cooler includes a single fan between the fin stacks, drawing air from one stack and pushing it through the other. With the fan installed, the Peerless Assassin 120 Mini measures 125mm x 110mm x 145mm (WxDxH). The height is reduced to 135mm without the fan. For comparison, the original Peerless Assassin 120 measures 125mm x 135mm x 157mm and comes with a twin 120mm push-pull fan arrangement. The Peerless Assassin 120 Mini weighs 820g, including the fan.
The cooler is compatible with various CPU socket types, including LGA1700, AM5, AM4, and LGA1200. We know the cooler will be available in black and white, but pricing and the release date have not been shared yet.

KitGuru says: If you plan to build a compact system with limited CPU cooler clearance, the Thermalright Peerless Assassin 120 might be worth checking out. The original Peerless Assassin is still quite good (especially considering its price), so we expect something similar from its Mini sibling.
