Thermalright Peerless Assassin 140 Digital White CPU Cooler - Dual-Fan

In this review of the Peerless Assassin 140 Digital White CPU cooler, the bottom line is simple: it is for PC builders who need strong air cooling with modern visual controls. The cooler pairs a dual-tower heatsink and two high-flow fans with a magnetic ARGB digital display, making it a good pick for systems that mix performance cooling and chassis showmanship. The single biggest reason to buy is the combination of six 6mm heat pipes with AGHP version 5.0 and high airflow fans that handle today's mid- to high-TDP CPUs while offering an easy-to-read temperature display.

Key Features

• Dual-tower design: The two-tower heatsink structure increases fin surface area for consistent heat dissipation across sustained loads.
• Six 6mm heat pipes: AGHP version 5.0 heat pipe technology and precision reflow soldering improve thermal transfer and reduce orientation-related performance loss.
• High airflow fans: The included 120mm/140mm S-FDB fans spin up to 1850/1500 RPM with up to 82/77.8 CFM for strong cooling while remaining PWM-controllable.
• Magnetic ARGB display: A magnetic top cover with a digital display shows temperature and occupancy data and can be colour-mapped via TRCC control software for visual feedback.
• 165mm height compatibility: With an overall height of 165mm, the cooler fits most mainstream ATX cases while still allowing for tall memory in many builds.
• Wide socket support: Comes with SS2 fasteners and dual-platform mounting grommets to support AMD AM4/AM5 and a broad range of Intel sockets.

Who It's For

The Peerless Assassin 140 is ideal for PC builders who want near-high-end air cooling without moving to a liquid loop and who value on-system telemetry and style via the ARGB magnetic display. Gamers and content creators running mid to high TDP chips on AMD AM4/AM5 or modern Intel platforms will appreciate the six heat pipes and dual fans.

Users with very compact cases under 165mm of cooler clearance or those needing extreme overclocking headroom beyond high-performance air cooling should consider larger custom solutions or AIO liquid cooling instead. Also note AMD AM4 installs require your motherboard backplate, which is not included.

Pros & Cons

Pros

• Strong thermal transfer from six 6mm AGHP heat pipes and a micro-engraved copper base that improves sustained cooling.
• Two S-FDB fans deliver high airflow and PWM control while keeping noise moderate at rated RPMs.
• Magnetic ARGB digital display provides on-case temperature readout and software-controllable color mapping for system monitoring.

Cons

• At 165mm height, the cooler may not fit in very small cases and requires checking clearance before purchase.
• AMD platform installation requires the motherboard's original backplate, which is not supplied with the cooler.

Our Verdict

The Peerless Assassin 140 Digital White is a strong value for builders who want effective air cooling plus modern visual telemetry. It combines six AGHP heat pipes, a dual-tower heatsink and high-flow S-FDB fans to cool mid- to high-TDP CPUs reliably, while the magnetic ARGB display adds useful temperature feedback and aesthetics. Choose this cooler if your case has at least 165mm clearance and you want a performance-oriented white air cooler with smart visuals.

Frequently Asked Questions

Does this cooler fit in standard ATX cases?
The cooler is 165mm tall, so it fits most mainstream ATX cases but you should verify case-to-CPU cooler clearance before buying.

Is the ARGB display controllable?
Yes, the magnetic digital display supports ARGB effects and can show temperature figures that can be colour-mapped using the TRCC control software.

Does it include mounting for AMD and Intel?
Yes, it ships with SS2 fasteners and dual-platform mounting grommets for AMD AM4/AM5 and a wide range of Intel sockets; AMD installs require the motherboard original backplate.
