Frequently asked questions

Is the Thermalright Peerless Assassin 120 SE compatible with AM5 sockets?

Yes, this cooler supports AM5 processors. The specifications list AM5 alongside other modern sockets like LGA 1851 and LGA 1700. You can install it on your AMD Ryzen 7000 or 9000 series motherboard without needing special adapters. It ensures broad compatibility for your current platform.

Does the PA120 SE fit in small ITX cases?

It depends on your case height. The cooler measures 6.1 inches in height. You should check your case specifications to ensure it can accommodate this clearance. If your case has low height restrictions, you might need a lower-profile alternative like the Mini version, which stands at 4.92 inches.

What is the difference between the SE and Dual Fan versions?

The SE version typically includes a single fan, while the Dual Fan variant adds a second 120mm fan for increased airflow. Both share the same dual-tower design and six heat pipes. The Dual Fan model offers slightly better cooling potential but requires more vertical space inside your computer case.

Does the Peerless Assassin 120 SE have RGB lighting?

No, the SE model does not include RGB lighting. It is designed for users who prioritize thermal efficiency and socket compatibility over aesthetic features. If you want addressable RGB effects, you should look at the Burst Assassin 120 ARGB instead, which includes lighting and a single-tower design.

How many heat pipes does the Thermalright PA120 SE have?

It features six heat pipes. These pipes help transfer heat from the CPU base to the aluminum fins efficiently. This configuration allows the dual-tower design to dissipate thermal energy effectively, making it a solid choice for mainstream processors that generate moderate to high heat loads.

Is the aluminum version of the PA120 SE a good budget option?

Yes, the aluminum version is a solid choice for budget builds. It uses a dual-tower aluminum design with six heat pipes to deliver consistent cooling. You get high airflow and strong socket compatibility without the extra cost of premium materials. It fits users who value performance over aesthetic lighting.

Can I use the Mini Black version for AM5 builds?

Yes, the Mini Black version supports AM5 sockets. It is designed for compact cases with height restrictions. While it provides adequate performance for standard processors, it may not match the raw cooling power of the larger dual-tower models. It is ideal if you prioritize case compatibility in tight spaces.

What fan size does the Peerless Assassin 120 SE use?

It uses a 120mm fan. This standard size ensures good airflow across the heat sink fins. You can expect efficient cooling performance from this fan size. If you prefer quieter operation, you might consider the Dual Fan version, which also uses 120mm fans but adds a second unit for better heat dissipation.
