This article covers Thermalright Peerless Assassin 120 SE ARGB CPUエアクーラー. The Thermalright Peerless Assassin 120 SE ARGB is a dual-tower CPU cooler featuring six 6mm heat pipes and two 120mm ARGB PWM fans.
It supports a wide range of sockets including Intel LGA115X/1200/1700 and AMD AM4/AM5, making it compatible with modern Ryzen and Core processors. Despite its impressive 265W TDP cooling capacity, the cooler stands only 155mm tall, fitting most mid-tower cases.
The two TL-C12C-S fans operate at up to 1550 RPM with a noise level of 25.6 dBA, offering a great balance between performance and acoustics.
The cooler is compatible with Intel LGA115X/1200/1700 and AMD AM4/AM5 sockets. Its dimensions are 125 x 135 x 155 mm (W x D x H) and it weighs approximately 0.97 kg.
The two 120mm PWM fans use standard 4-pin connectors, and the ARGB lighting connects via a 3-pin 5V header for motherboard synchronization. The offset fin stack design provides clearance for tall memory modules, though front fan position may need adjustment with very high-profile RAM.
Always verify your case's maximum CPU cooler height (155mm required) and memory clearance before purchase. Released around 2022, the Peerless Assassin 120 SE ARGB remains a popular choice in the mid-high performance segment.Check the retailer's page for the latest price.
The package includes mounting kits for Intel and AMD, a backplate, thermal paste, fan clips, and an ARGB controller (depending on version). This cooler is widely regarded as one of the best value air coolers, often competing with premium models at a fraction of the cost.
This cooler is ideal for users building a quiet, high-performance air-cooled system with mid-range to high-end CPUs like an Intel Core i5/i7 or AMD Ryzen 5/7. It's also a great alternative to liquid cooling for those who want excellent performance without the risk of pump failure or leaks.
If you're building a themed PC with RGB lighting, the ARGB fans add a customizable aesthetic. However, ensure your case has at least 160mm of CPU cooler clearance (the cooler is 155mm) and that your RAM height is not excessive.
