Thermalright Peerless Assassin 120 SE 6-heatpipe CPU cooler 🧊

This dual-tower air cooler brings robust heat management to mid‑range and high‑performance desktop builds, with a taller yet compact profile that helps keep temperatures lower under sustained loads. It pairs two 120 mm PWM fans with six heat pipes to increase airflow and improve thermal transfer, which makes it practical for gaming, content creation and overclocking scenarios.

Key Points

The Thermalright Peerless Assassin 120 SE Black combines a dual‑tower aluminium fin stack with six copper heat pipes and two standard 120 x 120 x 25 mm PWM fans. It includes mounting hardware for both Intel and AMD sockets, and the cooler’s 135 mm height aims to balance cooling capacity with case and memory clearance. Fans are tuned for a moderate noise level while offering a stronger airflow than single‑tower alternatives. 😎

Usage Recommendations

Allow some space around the cooler to ensure unobstructed airflow, particularly if your build uses tall memory modules or compact ITX cases. When installing, follow the supplied mounting parts to match the socket on your motherboard and check clearance for RAM height before fitting the cooler. Fans are PWM controlled so they can be connected to a motherboard header to adjust speed automatically based on CPU temperature. 🔧

Advantages and Considerations

The double‑fan, double‑tower arrangement increases the effective fin area and tends to outperform single‑tower designs in sustained loads, according to the manufacturer. The modest 135 mm height improves compatibility with many mid‑tower cases, but it may still conflict with very compact enclosures or some large RAM heatsinks. Noise remains comparatively low at typical operating speeds, though peak airflow figures are achieved closer to the stated maximum RPM. 🌀

Consider that while the core components are optimised for balance between size and performance, very high TDP CPUs might demand larger coolers or liquid alternatives if you plan extreme overclocking. The product includes platform‑specific brackets and instructions to aid installation across the listed Intel and AMD sockets.
