Overview

The Thermalright Peerless Assassin 120 (PA120) is a dual-tower CPU air cooler featuring six 6mm heat pipes and two 120mm PWM fans. It supports a wide range of sockets including Intel LGA 1700/1200/115X/2011/2066 and AMD AM4/AM5, making it compatible with modern Ryzen and Core processors. With a rated TDP of 245W, this cooler is designed to handle mid-range to high-end CPUs efficiently. The included TL-C12 fans spin up to 1500 RPM while keeping noise levels at a modest 25.6 dBA, striking a good balance between performance and acoustics.

Connectivity & Compatibility

The cooler measures 125mm (W) x 135mm (D) x 157mm (H), fitting into most standard ATX cases. Its offset design helps avoid interference with RAM slots, allowing clearance for most DDR4 and DDR5 memory modules. Socket support covers Intel LGA 115X/1200/1700/2011/2066 and AMD AM4/AM5. The package includes mounting kits for both platforms, and installation is straightforward without requiring special tools.

Product Info

The Thermalright Peerless Assassin 120 is priced around $40-50 USD (approximately ¥6,000 JPY) on , positioning it as a cost-effective mid-range air cooler with excellent value. Included accessories: two TL-C12 PWM fans, Intel and AMD mounting kits, thermal grease, and an instruction manual. Warranty typically ranges from 1 to 2 years depending on the region.

Best Use Cases

This cooler is ideal for budget-conscious PC builders who need reliable cooling for CPUs like the Ryzen 7 or Core i7 series. Its 245W TDP rating ensures adequate thermal headroom for gaming and content creation workloads. It is also a great choice for users who prefer air cooling over liquid cooling to avoid pump noise and leakage risks. The simple, robust design offers long-term reliability. Additionally, noise-sensitive users will appreciate the PWM-controlled fans that stay quiet at idle and remain relatively subdued under load at 25.6 dBA.

Things to Consider

Before purchasing, verify your case's maximum CPU cooler height. At 157mm, the PA120 fits most mid-tower cases but may not clear compact or slim chassis. RAM clearance is generally good, but users with tall heat-spreader memory modules may need to use the second DIMM slot first to avoid physical interference. Lastly, the 245W TDP rating is a theoretical maximum; real-world performance depends on case airflow and ambient temperature. For sustained heavy loads, ensure your case has adequate intake and exhaust fans.
