Product Description

This Thermalright Peerless Assassin 120 SE Black CPU Cooler is in brand new condition and offers outstanding, flagship-tier cooling performance for modern desktop processors.

Featuring a dual-tower heatsink layout, 6 high-performance anti-gravity heat pipes (AGHP), and a nickel-plated pure copper base, this cooler easily manages heavy thermal loads. Built with a high TDP (Thermal Design Power) capacity of up to 265W, it is fully capable of taming power-hungry, high-end processors. It easily handles top-tier CPUs including:

  • AMD Ryzen: 7800X3D, 7900X, 7950X, 9800X3D, 9950X

  • Intel Core Ultra: Ultra 7 265K, Ultra 9 285K

  • Intel Core 13th/14th Gen: i7-13700K / 14700K, i9-13900K / 14900K

The cooler comes equipped with two high-efficiency TL-C12C 120mm PWM fans utilizing S-FDB bearings to deliver strong airflow while maintaining low noise output. A tube/packet of Thermalright thermal paste is included in the box.

Note on Compatibility: At a total height of 155mm, this cooler will comfortably fit the vast majority of standard ATX and Micro-ATX mid-tower cases. However, if your PC case is smaller than standard cases (such as certain budget, compact, or Mini-ITX chassis), or if you are using tall RGB RAM sticks that require the front fan to sit slightly higher, please check your case's CPU cooler height clearance before ordering.
