Pros & Cons
Pros
- ✓ Six 6mm AGHP 4th-gen heat pipes feed a dual-tower, 96-fin aluminum stack
- ✓ Pure copper contact base under all six pipes for direct CPU heat transfer
- ✓ 66.87 CFM TL-D12W PWM fan stays at or below 25.6 dB(A)
- ✓ S-FDB bearing rated for 20,000 hours with anti-vibration silicone feet
- ✓ Covers AM4, AM5 and Intel LGA 1150-1851 with included mounting hardware
Cons
- ✗ 120mm dual-tower height can foul tall RAM or small-form-factor cases
- ✗ Ships with a single 120mm fan, so push-pull needs a second purchase
- ✗ 1500 RPM ceiling limits headroom versus 140mm or 2000 RPM coolers
- ✗ Air cooling only, so no AIO-style aesthetics or display block

Key Features
- [Brand Overview] Thermalright is a Taiwanese brand with more than 20 years of development history. It has a certain degree of popularity in the domestic and international markets, and has a decisive influence in the cooler market. We have been focusing on the research and development of computer accessories. The R&D product line includes: CPU coolers, CPU water cooling coolers, case fans, thermally conductive silicone grease, accessories and other products.
- [AGHP Technology] 6x6mm heatpipes adopt AGHP upgraded 4th generation technology to solve the effect of anti-gravity caused by vertical/horizontal direction, and 6 pure black fully plated heatpipes, which will bring out the heat dissipation to a better level with the help of 12cm performance fans.
- [Thermal Advantage] CPU cooler's strong heat dissipation is created by 6 heatpipes + dual tower + performance fan, dual tower structure for 48 pieces of all-aluminium fins * 2, to a certain extent, increase the cooling area, by the pure copper base to heat transfer to the 6 heatpipes, and then dispersed to the dual tower, and finally by the pc fan will be blown out of the heat dissipation, to achieve the best cooling effect!

- [Stable output] CPU cooler with high-performance fan with PWM temperature control function, shock-absorbing silicone feet around to reduce fan noise, anti-touch fan blade design to improve safety, and S-FDB bearing is a solution to the fan lifting jitter vibration. The S-FDB bearing solves the problem of fan lifting vibration. It improves the cooling performance to a great extent.
- [PWM Fan] CPU Fan Model: TL-D12W; Standard Size PWM Performance Fan: 120x120x25mm (4.72x4.72x0.98 inches); Fan Speed (RPM): 1500rpm±10%; Power Port: 4-pin; Voltage: 12V; Air Flow: 66.87CFM (Max); Noise Level ≤ 25.6dB(A) The S-FDB bearing of CPU fan has an industrial life of up to 20,000 hours, which can ensure the service life of air-cooling radiator.
