Air cooler Akasa Alucia H4 12 cm Black Blue Hydro Dynamic Bearing

Alucia H4 is a 120 mm air cooler designed for CPUs with up to 185 W TDP. It combines a compact all-black heatsink with a blue 120 mm fan driven by a Hydro Dynamic Bearing for reduced noise and extended life. Four copper heat pipes use Direct Touch Technology to transfer heat efficiently from the CPU to the high-density fins. The cooler includes a mounting kit compatible with a wide range of Intel and AMD sockets and comes with T5 Pro-Grade Plus thermal paste.

Advantages

The cooler features four copper heat pipes with Direct Touch Technology for efficient heat dissipation and a high-density fin stack electro-painted in black for corrosion resistance. The Alucia fan implements advanced blade geometry, intelligent PWM speed control and damping pads to minimise vibration. Hydro Dynamic Bearing improves lubrication and longevity, with rated life up to 40,000 hours. A metallic Akasa badge provides a premium aesthetic.

How to use

Install the Alucia H4 using the supplied mounting kit following the motherboard-specific instructions. Apply the included T5 Pro-Grade Plus thermal paste on the CPU heatspreader in a thin, even layer before seating the cooler to ensure good thermal contact. Connect the fan to the CPU_FAN or appropriate PWM header to allow automatic speed regulation. Ensure clearance for RAM modules and confirm orientation for optimal airflow through the case.

Recommendations

For reliable performance, use the cooler on CPUs up to 185 W TDP and enable PWM control in BIOS for dynamic fan speed. Check that your case and RAM clearance accommodate the cooler’s 120 mm width and heatsink profile. Replace thermal paste if the cooler is removed and reinstalled.
