Thermalright Peerless Assassin 120 White CPU Air Cooler - Quiet Dual

In this review the Thermalright Peerless Assassin 120 White is judged as a capable midtower CPU air cooler for builders who want strong cooling in a compact footprint. It stands out for pairing a dual 120mm fan setup with six copper sintered heat pipes and a pure copper base, delivering real-world temperature control without a bulky size. The white aluminium cover and measured noise profile make it suitable for mainstream gaming rigs and productivity PCs where both looks and cooling matter.

Key Features

• Six copper heat pipes: Six pure copper sintered heat pipes transfer heat quickly from the CPU contact plate to the aluminium fins for sustained thermal performance.
• Dual TL-C12W PWM fans: Two 120mm PWM fans provide high airflow up to the specified CFM while allowing motherboard control for quieter idle operation.
• Pure copper base and reflow welding: A full electroplating reflow welding process and a pure copper base improve contact and durability for consistent heat conduction.
• AGHP technique to reduce orientation loss: The 66mm heat pipe design employs AGHP technology to mitigate inverse gravity effects when the cooler is mounted vertically or horizontally.
• Compact double tower size: At 125 x 135 x 157mm the doubletower heatsink fits many mid towers while still offering stronger cooling than single tower designs.
• Platform compatibility: Ships with metal fasteners and mounting hardware for Intel and AMD sockets including AM4, AM5 and recent Intel LGA platforms.

Who It's For

The Peerless Assassin 120 White is best for PC builders who want a balance of aesthetics and cooling: gamers running midrange to highefficiency CPUs, content creators on air cooling, and users who appreciate a white cooler to match their build. It suits cases with clearance for a 157mm cooler and users who will benefit from PWM fan control to tune noise versus performance.

Users who need the absolute smallest lowprofile cooler or who require extreme overclocking headroom may want to look at larger tower coolers or AIO liquid solutions. Also, silentonly enthusiasts should test for fan whine on higher RPMs, since some reports indicate audible variation under load.

Pros & Cons

Pros

• Excellent heat transfer from six copper sintered heat pipes and a solid copper base.
• Good balance of airflow and control using dual PWM TLC12W 120mm fans.
• Attractive white aluminium cover that complements modern builds while remaining compact.
• Broad socket compatibility with supplied metal fasteners for Intel and AMD platforms.

Cons

• Some users may notice fan whine at higher speeds, so noise behavior can vary between systems.
• Assembly hardware receives mixed feedback, and a careful install is required to avoid mounting frustration.

Specifications

Our Verdict

The Peerless Assassin 120 White is a strong pick for mainstream builds that need reliable cooling, a clean white appearance, and flexible PWM fan control. It offers clear value with a compact doubletower layout and six copper heat pipes; just be prepared for occasional fan noise at full load and follow mounting instructions carefully during installation.

Frequently Asked Questions

Will this cooler fit in a midtower case?
Yes, at 157mm height it fits most midtower cases, but check top clearance in your chassis before purchasing.

Is it compatible with AM5 and Intel LGA1700?
Yes, the cooler ships with mounting hardware to support AM4/AM5 and multiple Intel sockets including LGA1700.

How quiet is the cooler in real use?
The fans are designed for low noise and PWM control helps at idle, but some systems report audible whine under higher fan speeds.
