Pros & Cons

Pros

  • ✓ Dual PWM fans (120mm TL-C12B V2 plus 140mm TL-D14CB) move up to 66.17 CFM
  • ✓ Rated 25.6 dB(A) or lower even at the full 1500 RPM fan speed
  • ✓ Fits AM5/AM4 and Intel LGA 1700/1851/1200/1156/1155/1151/1150 out of the box
  • ✓ Reflow-soldered micro-engraved copper base under black nano-painted aluminum fins

Cons

  • ✗ 158mm height targets mid and full towers, ruling out most small-form-factor cases
  • ✗ Fans top out at 1500 RPM with no listed low-noise or high-speed alternative
  • ✗ Mismatched 120mm and 140mm fans mean replacements require two different sizes
  • ✗ No published TDP rating, so headroom on high-wattage CPUs is unstated

Key Features

  • [Better Heat Dissipation] The cooler is mainly composed of a twin-tower body with symmetrical mecha-shaped fins + pure copper six heatpipes + high-performance dual fans. The pure copper base senses the CPU temperature, then disperses the temperature from the heatpipes to the large-area aluminium fins, and then the 1500RPM high-volume dual fans dissipate the heat to achieve a good heat dissipation effect.
  • [Optimised Body Details] The body of the radiator features a black nano-painted layer, a combination of black-painted buckled FIN aluminium fins and heatpipes, and a precision reflow soldered micro-engraved copper base to form the cpu double towers cooler.
  • [158mm Height] The height of the cpu cooler is 158mm, which is suitable for large and medium-sized chassis, and is compatible with the installation of high-marshal memory and graphics cards, and the all-aluminium fins of the main body can bring the maximum cooling area.
  • [Dual PWM Fans] TL-C12B V2 Fan and TL-D14CB; Standard size PWM fan: 120x120x25mm /140x140x27mm; Fan speed (RPM): 1500rpm±10%; Power interface: 4pin; Voltage: 12V; Air volume: 66.17 CFM (MAX); The noise value is≤25.6dB (A), and dual fans can provide stronger air flow, further improving the heat dissipation effect of the cpu air cooler.
  • [Compatibility] CPU cooler slot support: Intel: LGA1150/1151/1155/1156/1200/1700/1851; AMD: AM4/AM5; for different CPU slot platforms, the cooler's mounting kit provides the appropriate mounting plate or fasteners, can be combined with the installation instructions or follow the tutorials to Install.
