What stands out
- Six 6mm AGHP heat pipes with precision reflow soldering for efficient heat transfer.
- Dual 120mm fans with S-FDB bearings offering up to 1850RPM speed and 2.21 mm H2O static pressure.
- Magnetic top cover with a digital display board for visual customization.
- 162mm overall height compatible with mainstream ATX chassis and high-profile memory.
- Broad socket support including AM4, AM5, LGA1700, and LGA1851.
Who it fits
Good fit for
You should consider this cooler if you use an AMD AM4, AM5, or Intel LGA1700/1851 processor and want reliable air cooling without excessive noise. The dual-tower design and six heat pipes handle modern dual-platform heating characteristics well. Its 162mm height fits most mid-tower cases, and the included mounting clips simplify installation. If you prefer a black aesthetic with ARGB lighting and a unique digital display, this unit offers both performance and style for your build.
Who should skip it
You should look elsewhere if your case has a CPU cooler height limit below 162mm, as this dual-tower design will not fit. The product data notes that AMD installation requires the motherboard's original backplane, which is not included. If you need silent operation below 25.6 dB, the maximum fan speed may be too loud for your preference. Additionally, if you prefer a white color scheme, you must select the specific white variation, as this listing describes the black model.
Verdict: This cooler delivers solid thermal performance through its six heat pipes and dual fans, making it a practical choice for standard ATX builds. The digital display adds a unique visual element without compromising its core cooling specifications.
Key specs explained
Fan Size: 120mm
This indicates the fans measure 120 millimeters on each side. This is the standard size for most mid-tower cases, ensuring the cooler fits without blocking RAM slots. You benefit from widespread case compatibility. When shopping, check your case specifications to confirm it can accommodate 120mm fans in the front or top positions for optimal airflow integration.
Heat Pipes: 6
The cooler contains six copper heat pipes. These pipes transfer heat from the CPU base to the aluminum fins efficiently. More pipes generally mean better heat distribution across the fins. You benefit from stable temperatures under load. Compare this count with other air coolers; six pipes is a common standard for high-performance dual-tower designs.
Tower Design: Dual-Tower
This design features two stacks of fins with fans blowing through both. It provides a larger surface area for heat dissipation compared to single-tower models. You benefit from improved cooling capacity for hotter processors. When comparing options, dual-tower coolers are typically larger but offer superior thermal performance for high-end CPUs in similar price ranges.
Socket Compatibility: AM4/AM5, LGA1700/1851
This lists the processor sockets the cooler supports, including AMD AM4 and AM5, and Intel LGA1700 and LGA1851. You benefit from broad modern platform support. Ensure your motherboard socket matches one of these. Check your specific CPU socket type before purchasing to guarantee physical mounting compatibility with the included brackets.
Design and build details
The listing describes a dual-tower layout with two 120mm fans. This structure uses six pure copper heat pipes and a pure copper base. The pipes utilize AGHP technology to manage heat transfer. The base features precision reflow soldering for better contact with the CPU. You get a magnetic top cover that includes a digital display board. This design adds a visual element while maintaining the cooling function. The unit comes in a black finish with ARGB lighting support on the fans.
Dimensions are listed as 138x125x162mm. The height of 162mm means you must check your case clearance. It fits mainstream ATX chassis but may interfere with tall RAM modules. The fans operate at 1850RPM with S-FDB bearings. This bearing type suggests longer life and stable operation. Airflow is rated at 88.89CFM with noise levels at 25.6dB. You benefit from efficient cooling without excessive sound. The fans use a 4-pin PWM interface for speed control.
Weight is noted as 3.53 ounces. This is light for a dual-tower cooler. The listing states it includes mounting clips for AMD AM4/AM5 and Intel LGA1700/1851/1150/1151/1200 sockets. You need the original motherboard backplane for AMD installation. The design aims for compatibility with high-capacity memory. The digital screen offers a unique look for your build. According to the listing, this combination balances performance and aesthetics.
Setup and everyday use details
Installing this cooler requires matching the included mounting clips to your specific motherboard socket. The listing confirms compatibility with AMD AM4 and AM5 platforms, as well as Intel LGA 1851, 1700, 1150, 1151, and 1200. You must use the original backplane for AMD installations, which is not included in the box. Follow the provided instructions or tutorial for proper placement. The cooler stands 162mm tall, fitting mainstream ATX chassis. This height allows for the installation of high-capacity memory modules and graphics cards without physical interference. The dual-tower design with dual fans supports this clearance. For daily operation, the fans run at 1850RPM with a ten percent tolerance. This speed generates up to 88.89 CFM of air volume and 2.21mm H2O of static pressure. Noise levels remain at or below 25.6 dBA. The fans use S-FDB bearings, which are designed for long-term durability. The magnetic top cover features a digital display, adding a visual element to your build. The cooler connects via a 4-pin PWM interface, allowing your motherboard to adjust fan speed based on thermal load. The six pure copper heat pipes and precision reflow soldering base ensure efficient heat transfer from the CPU to the aluminum fins. This setup provides reliable cooling for dual-platform systems without requiring complex configuration.
Check compatibility and setup needs
Before purchasing the Thermalright Peerless Assassin 120 Digital, verify your case interior height. The cooler stands 162mm tall, which fits most ATX cases but may clash with large RAM modules. Check your memory clearance against the fan profile. You also need to ensure your motherboard socket is supported, including AM4, AM5, or LGA 1700/1851. This model adds a digital display feature not found in standard versions. You must manage the ARGB connection separately from your motherboard header. Keep the fans clean to maintain the specified 25.6dB noise level. This option suits users who want high performance with visible customization. It sits alongside other dual-tower coolers by offering unique aesthetics. Compare its 1850RPM speed and 88.89CFM airflow against simpler black models. If you prioritize silent operation, note the fan specifications carefully. Ensure your chassis allows for the dual-tower width. This cooler is a strong choice for modern dual-platform builds that need efficient heat dissipation without excessive bulk.
Check before you buy
- Verify case height exceeds 162mm for clearance.
- Check RAM height compatibility with dual fans.
- Confirm motherboard socket supports AM4, AM5, or LGA1700.
- Ensure ARGB header is available on motherboard.
