Thermalright Peerless Assassin 120 Digital CPU Air Cooler - Temp

In this review of the Peerless Assassin 120 Digital the bottom line is simple: this compact tower cooler is aimed at desktop builders who want strong thermal control and a convenient onboard temperature readout. It stands out for its integrated temperature display and robust six heat pipe layout, which together deliver sustained cooling for mainstream and highperformance CPUs. The review focuses on real use: installation, noise and cooling under load, and whether the digital display and TRCC control are genuinely useful in day to day system monitoring.

Key Features

• Digital Temperature Display: The front panel readout shows CPU temperature and usage plus graphics card data via the MB 9 pin/USB connection, making oncase monitoring straightforward without extra software.
• Six Heat Pipes: Six 6 mm copper heat pipes and a nickel plated C1100 copper base provide rapid heat transfer to the aluminum fin stack for steady cooling under sustained load.
• Dual Thickened PWM Fans: Two TLC12CX28 V2 120x28 mm PWM fans deliver up to 88.89 CFM at about 1850 RPM while keeping audible noise down to about 25.6 dBA in most use cases.
• AGHP GEN 5.0 Technology: The GEN 5.0 heat pipe design reduces orientation related performance loss, which helps maintain cooling efficiency whether the cooler is mounted vertically or horizontally.
• High TDP Capacity: With the full electroplating reflow welding process and design choices the cooler is rated to manage CPUs up to an advertised TDP around 265W, suitable for many highend chips.
• Platform Compatibility: Includes metal fasteners for Intel and AMD platforms, covering modern sockets such as Intel 1700/1851 and AMD AM4/AM5 for straightforward mounting.

Who It's For

The Peerless Assassin 120 Digital is best for PC builders who want an air cooler that pairs strong thermal performance with an oncase temperature display and cable connected monitoring. It is a good fit for gamers and content creators who run moderately heavy loads and value real time temperature feedback without relying only on software.

Users who need the absolute lowest noise or who require a very compact lowprofile cooler for small form factor cases should look elsewhere, as the cooler measures L125 x W110 x H162 mm without fans and uses dual 28 mm fans that need clearance.

Pros & Cons

Pros

• Excellent heat transfer thanks to six copper heat pipes and a nickel plated copper base.
• Integrated temperature display with TRCC control gives clear oncase monitoring of CPU and GPU temperatures and usage.
• High airflow 120x28 mm PWM fans push significant CFM while keeping noise at a reasonable level for the performance.
• Strong platform compatibility with included metal fasteners for Intel and AMD sockets.

Cons

• The cooler is not a lowprofile solution and requires adequate clearance inside mid tower and larger cases.
• At full fan speed the noise is noticeable compared with larger, slower fans optimized for nearsilent operation.

Specifications

Our Verdict

The Peerless Assassin 120 Digital is a sensible choice for builders who want strong air cooling with a builtin temperature display and modern socket support. It pairs six copper heat pipes and high CFM dual fans to keep CPUs well under control during sustained workloads, and the TRCC display adds convenient monitoring. It represents good value for users who accept a midtower footprint in exchange for reliable cooling and oncase temperature feedback.

Frequently Asked Questions

Does it support AM5 and Intel 1700 sockets?
Yes, the cooler ships with metal fasteners for both Intel and AMD platforms and supports modern sockets including AM4/AM5 and Intel 1700/1851.

How loud are the fans under load?
Fans run up to about 1850 RPM with a maximum measured noise around 25.6 dBA, which is audible but acceptable given the airflow delivered.

Can the digital display show GPU temperature?
The display and TRCC control can show CPU temperature and usage as well as graphics card temperature and usage when connected via the motherboard USB/MB 9 pin interface.
