This article covers Thermalright Assassin King 120 SE White ARGB CPUエアクーラー.

Overview

The Thermalright Assassin King 120 SE White ARGB is a mid-range CPU air cooler featuring a white color scheme and addressable RGB lighting. It utilizes five 6mm heat pipes and a 120mm PWM fan to efficiently cool CPUs with a TDP of up to 180W. The fan includes ARGB LEDs that connect to a standard 3-pin 5V ARGB header on the motherboard, allowing customizable lighting effects. With a height of only 148mm, it fits comfortably in most mid-tower cases, making it a versatile choice for budget-conscious builders. This cooler supports Intel LGA 1150/1151/1155/1156/1200/1700 and AMD AM4/AM5 sockets, covering a wide range of modern and older platforms. The included mounting kit is straightforward to install, even for first-time PC builders. The Assassin King 120 SE White ARGB strikes an excellent balance between cooling performance, noise levels, and price, earning it a strong reputation among DIY enthusiasts.

Connectivity & Compatibility

Socket compatibility includes Intel LGA 1150/1151/1155/1156/1200/1700 and AMD AM4/AM5. The cooler measures 120mm (W) x 73mm (D) x 148mm (H), so ensure your case has at least 148mm of CPU cooler clearance. The fan uses a 4-pin PWM connector for speed control via the motherboard's CPU fan header. ARGB lighting requires a 3-pin 5V addressable RGB header; if your motherboard lacks one, you can use an optional ARGB controller (not included).
