Expert Features Twin-Tower Titan Cooling Power – The PA120 SE uses a dual-tower aluminum heatsink layout engineered to maximize surface area and airflow, delivering ultra-stable thermal performance for modern multi-core CPUs. 6×6mm AGHP Anti-Gravity Heat Pipe System – Six C1100 pure-copper, nickel-plated heat pipes use AGHP (Anti-Gravity Heat Pipe) tech to eliminate performance loss from case orientation—vertical, horizontal, tilted spaceship mode… doesn’t matter. Premium Copper Base + Full Electroplating – A pure copper C1100 base, fully nickel-plated and joined with an electroplated reflow welding process, ensures rapid heat transfer, durability, and exceptional temperature consistency. Dual TL-C12C 120mm PWM Fans – Two 120×120×25 mm fans with 1550 RPM±10%, 66.17 CFM airflow, 1.53 mmH₂O pressure, and ≤25.6 dBA noise strike a perfect balance for heatsinks and radiators alike, powered by smooth long-life S-FDB bearings. Universal CPU Socket Compatibility – Supports Intel 115X / 1200 / 1700 / 17XX and AMD AM4 / AM5 platforms. Intel & AMD metal fasteners included (AMD uses motherboard’s stock backplate). RAM-Friendly Clearance – Slim-profile TL-C12C fans avoid bulky RAM interference, keeping installation clean, accessible, and stress-free. Enhanced Installation Experience – Comes with Thermalright’s redesigned SS2 mounting system for secure, even mounting pressure and easier setup. TF-7 Thermal Paste Included – High-performance Thermalright TF-7 paste arrives in the box for an optimal out-of-the-box cooling boost. Thermalright Heritage – From a respected Taiwan brand with 20+ years of cooling innovation—fans, pads, greases, mounts, and accessories trusted by global PC enthusiasts.
