Thermalright Peerless Assassin 120 SE ARGB White CPU Air Cooler

In this review the Thermalright Peerless Assassin 120 SE ARGB White is assessed as a midrange dual tower air cooler aimed at PC builders who want strong cooling and eye-catching lighting without spending top tier prices. The biggest reason to buy is its combination of a sixpipe copper core, dual 120mm PWM fans and ARGB lighting that together deliver notable cooling performance for mainstream to highperformance CPUs while remaining relatively compact at 125 x 135 x 155 mm.

Key Features

• 6 Heat Pipes with AGHP: Six pure copper sintered heat pipes use AGHP technique to reduce inverse gravity effects and keep heat transfer effective in different case orientations.
• Dual 120mm PWM Fans: The twin TLC12CWS fans run to 1550 RPM with a 4pin PWM connector for quieter, automatic speed control and up to 66.17 CFM airflow.
• ARGB Lighting: Colorful ARGB lighting on the fans and white heatsink cover adds visual flair for windowed cases and system builds focused on aesthetics.
• Solid Construction: A full electroplating reflow welded pure copper base and aluminum heatsink cover provide durability and consistent thermal contact.
• Wide Socket Support: Includes metal fasteners and mounting hardware for Intel 115x/1200/1700/1851 and AMD AM4/AM5 sockets for broad compatibility.
• Compact Double Tower: The double tower design balances improved dissipation with a 155 mm height that fits most midtower cases and leaves RAM clearance.

Who It's For

The Peerless Assassin 120 SE suits PC builders who want noticeably better cooling than stock coolers and prefer an air solution that also offers addressable RGB. It is a practical choice for gamers, content creators, and anyone running mid to high TDP CPUs who do not require custom water cooling.

Buyers who need the absolute quietest solution at very low RPMs or who are constrained by extremely tight case thermal layouts should consider low profile or larger tower coolers instead. Also, enthusiasts seeking extreme overclock headroom may still opt for larger highend towers or allinone liquid coolers.

Pros & Cons

Pros

• Strong cooling performance from six heat pipes and dual fans, frequently rated comparable to more expensive coolers.
• ARGB lighting and white cover improve system aesthetics for windowed cases.
• Easy installation with provided Intel and AMD metal fasteners and reasonable RAM clearance.
• Good value for performance, often beating stock coolers by a wide margin.

Cons

• Noise reports vary; some users find the fans louder under load compared with ultraquiet designs.
• At 155 mm height, it may not fit in very small form factor cases.
