Overview

The Thermalright Peerless Assassin 120 SE White ARGB is a dual-tower CPU air cooler that punches well above its price point. With six 6mm heat pipes and two 120mm PWM fans, it delivers cooling performance that rivals many 240mm AIO liquid coolers, making it a favorite among budget-conscious builders. This white variant features an ARGB fan and a white-coated aluminum fin stack, ideal for white-themed PC builds. It supports Intel LGA1700/1200/115x and AMD AM4/AM5 sockets, covering virtually all modern desktop platforms. The cooler is rated for up to 245W TDP, enough for high-end CPUs like the Core i7-13700K or Ryzen 7 7800X3D under normal workloads.

Connectivity & Compatibility

The Peerless Assassin 120 SE includes mounting hardware for Intel LGA1700/1200/1150/1151/1155/1156 and AMD AM4/AM5. Note that LGA1851 is not supported, but that socket is not yet mainstream. Both fans use standard 4-pin PWM connectors for speed control, and the ARGB lighting requires a 3-pin 5V addressable RGB header on your motherboard. Most modern boards have this, but older models may need an adapter. Memory clearance is adequate for most standard-height RAM, but tall heatspreaders (over 45mm) may interfere with the first DIMM slot. We recommend low-profile memory or installing the fan slightly higher (the included wire clips allow some adjustment).

Product Info

Released in late 2022, the Peerless Assassin 120 SE remains widely available. Pricing hovers around $35–$40 USD (approximately ¥5,000 in Japan), making it one of the best value dual-tower coolers on the market. The warranty is one year. The package includes: cooler body with pre-installed mounting brackets, two TL-C12CW-S ARGB fans, Intel and AMD backplates and brackets, a syringe of TF7 thermal paste, fan wire clips, and a manual. Market positioning is firmly in the budget-to-mid-range segment. Despite the low price, it competes directly with coolers costing twice as much, thanks to its efficient heat pipe layout and well-optimized fan curve.

Best Use Cases

Budget Gaming Builds: Perfect for pairing with a Core i5-13400F or Ryzen 5 7600. You get near-flagship cooling for a fraction of the cost, leaving more budget for a better GPU. White Aesthetic PCs: The white fins and ARGB fan blend seamlessly into all-white builds. It looks clean through a tempered glass side panel without being overly flashy. Quiet Office/Workstation: Under light loads, the fans are nearly inaudible. Even under full load, the 25.6 dBA noise level is unobtrusive. Great for content creation rigs where noise matters. However, this cooler is not ideal for: Small form factor cases: The 155mm height exceeds the clearance of many ITX cases. Always check your case's CPU cooler height limit. * Extreme overclocking: While capable, it will struggle to keep a heavily overclocked Core i9-13900K under 90°C in prolonged all-core workloads. For that, consider a 360mm AIO or a larger dual-tower like the NH-D15.
