- Four 6mm heatpipes equipped with 5th-generation AGHP technology to prevent orientation-based thermal loss
- High-velocity 120 mm ARGB fan delivering up to 2400 RPM for enhanced thermal headroom
- Cohesive all-white aesthetic with integrated addressable RGB lighting
- Lacks Intel mounting hardware, strictly limiting compatibility to AMD AM4 and AM5 sockets
- High 2400 RPM peak fan speed produces notable acoustic noise unless governed by a custom PWM curve
Overview
Clean monochromatic styling pairs with proven thermal dissipation mechanics in a single-tower footprint tailored specifically for modern AMD desktop platforms. Utilizing four 6mm copper heatpipes treated with Thermalright’s fifth-generation Anti-Gravity Heat Pipe (AGHP) engineering, the heatsink counteracts gravitational capillary resistance to maintain steady phase-change thermal transfer regardless of whether the system chassis is oriented horizontally or vertically. The stacked aluminum cooling fins feature a uniform white surface treatment, presenting an understated aesthetic that integrates cleanly into light-themed systems without crowding adjacent memory slots.
Airflow is managed by a single 120 mm TL-N12W-R9-S V2 ARGB fan tuned for high-velocity output, scaling up to 2400 RPM to drive air through the dense fin array. While this elevated rotational threshold provides ample headroom during peak processing spikes, running the fan at maximum RPM generates substantial acoustic output, making proper PWM fan curve tuning essential for daily operational quietness. Integrated addressable RGB lighting illuminates the frosted fan blades evenly, allowing standard motherboard headers to coordinate illumination without requiring proprietary background software.
Installation relies on direct mounting hardware tailored exclusively for AMD Socket AM4 and AM5 platforms, utilizing the stock backplate for predictable retention pressure and straightforward setup. The trade-off for this dedicated configuration is the complete absence of Intel mounting brackets in this SKU, eliminating cross-platform migration paths. For builders standardizing on AMD hardware, the cooler delivers dependable physical construction and capable thermal transfer within a focused, single-tower profile.
