Thermalright Peerless Assassin 120 White CPU Cooler - Dual Tower

In this review of the Thermalright Peerless Assassin 120 White CPU Cooler the bottom line is simple: it is a compact dual-tower cooler aimed at builders who want strong cooling without a large footprint. The reviewer found the combination of six heat pipes, a pure copper base and twin 120mm PWM fans delivers notable temperature drops on both AMD and Intel mainstream CPUs, while the white nanoscale finish and ARGB fans make it a tidy visual match for white builds. Installation is practical thanks to included Intel and AMD metal fasteners and an offset asymmetric layout that frees the first PCIe slot and memory clearance.

Key Features

• Double tower heatsink: The twin-tower aluminum design increases the effective heat dissipation area to 9600cm2 for improved sustained cooling.
• Six heat pipes with AGHP: Six pure copper sintered heat pipes use AGHP technique to address inverse gravity effects and optimize heat transfer in different orientations.
• Dual TL-C12W PWM fans: Two 120x120x25mm PWM fans provide up to 1500RPM and about 66.17 CFM airflow for quiet, effective cooling under load.
• Offset asymmetric layout: The cooler is designed to leave room for the first graphics card slot and memory modules, easing installation in tighter builds.
• White nanoscale finish and ARGB: A full electroplating reflow welding process and nanoscale white spray deliver a clean aesthetic while the fans add colorful ARGB lighting.
• Broad socket support: Mounting hardware covers modern Intel and AMD sockets including LGA 1700 and AM4/AM5 for wide compatibility.

Who It's For

The Peerless Assassin 120 White is best for PC builders who want a balance between strong air cooling and a compact tower height of 157mm, making it suitable for mid-tower and some compact cases. It is a particularly good fit for users running mainstream high-performance CPUs who want quieter operation and improved thermals without moving to a large 140mm or full-size tower cooler.

It is less suitable for extreme overclockers seeking the absolute top thermal headroom or for very small form-factor cases that cannot accept a 157mm tall cooler. Also, builders who require the absolute lightest weight or lowest profile should compare low-profile or top-flow designs instead.

Pros & Cons

Pros

• Excellent cooling for its size thanks to a 9600cm2 dissipation area and six heat pipes.
• Quiet operation with twin PWM fans that move a lot of air without high noise levels.
• Thoughtful layout that preserves first PCIe slot and memory clearance for easier installation.
• Solid build quality and attractive white finish with ARGB lighting for aesthetic builds.

Cons

• At 157mm height it still requires checking case clearance; not for the smallest SFF enclosures.
• The cooler adds weight to the motherboard and may be overkill for ultra-low TDP builds.

Specifications

Our Verdict

The Peerless Assassin 120 White is a compelling mid-height dual-tower cooler that gives mainstream enthusiasts strong cooling, quiet fans and a clean white aesthetic at a reasonable value. It suits builders who need reliable thermal performance without jumping to larger coolers and who appreciate ARGB accents; just confirm your case clearance before buying.

Frequently Asked Questions

Will this cooler fit in my mid-tower case?
It requires about 157mm of clearance in height, so measure the available CPU cooler clearance in the case before installing.

Does it support modern Intel and AMD sockets?
Yes, the package includes metal fasteners and mounting parts for Intel LGA 1700 and common 115x/1200/2066/2011 sockets and AMD AM4/AM5.

Are the fans quiet under load?
Customers report quiet operation; the TL-C12W fans top out at around 1500RPM and are rated near 25.6 dB(A), providing good airflow without being loud.
