The Thermalright Peerless Assassin 120 SE Extreme is a robust, dual-tower CPU air cooler designed for PC builders and enthusiasts who need reliable thermal management for modern processors. It offers exceptional cooling performance through its six-heatpipe architecture and dual-fan layout, making it an excellent value for high-wattage CPUs. One caveat for prospective users is that its dual-tower design is quite large, which may cause clearance issues with certain tall RAM modules or compact PC cases.

Yes, the Thermalright Peerless Assassin 120 SE Extreme explicitly supports the LGA 1851 socket.
Yes, standard thermal interface material is typically included with the mounting kit.
Due to its dual-tower design, it may overhang RAM slots; low-profile RAM is highly recommended.
Yes, the unit uses standard 120mm PWM fans, allowing you to swap them with other 120x120x25mm fans if desired.
The mounting system is straightforward, though the size of the cooler makes it slightly more challenging than smaller single-fan units.
Depending on your environment, cleaning the dust out every 6 months will maintain maximum cooling efficiency.
Check the PWM settings in your BIOS; ensure the fan cables are securely connected to the CPU_FAN header.
Verify that the thermal paste was applied correctly and that the cooler base is tightened evenly across the CPU.
Ensure the 4-pin header is plugged into the correct motherboard port and check that the fan blades are not obstructed by cables.
Installing the cooler requires mounting the backplate specific to your processor socket (LGA 1700/1851 or AM4/AM5). Ensure you have sufficient clearance in your chassis; measure the distance from the motherboard to the side panel to ensure it is at least 155mm. When installing, apply a pea-sized amount of thermal paste to the CPU surface before securing the base plate. To maintain performance, periodically remove dust from the heatsink fins and fan blades using compressed air every 6 to 12 months to prevent airflow blockages.
