CPU-koeler Akasa VIPER H6L – tower-luchtkoeler van Akasa (model AK-CC4034HP01)

Akasa VIPER H6L is a low-profile tower-style CPU air cooler designed for compact and standard desktop builds. The model AK-CC4034HP01 combines six heat pipes, aluminum fins and a quiet 120 mm PWM fan with S-FLOW blades to provide active and passive heat dissipation. With a height of 76 mm and a compact footprint of 120 × 120 × 76 mm, the VIPER H6L fits small form factor (SFF) systems while supporting mainstream Intel and AMD sockets and a rated TDP of 165 W.

Advantages

The VIPER H6L delivers balanced cooling performance and low noise through a 120 mm fan operating between 600 and 1900 rpm, offering maximum airflow up to 83.63 CFM and air pressure up to 2.98 mm-H2O. Its six copper heat pipes paired with aluminum fins improve thermal transfer while maintaining a lightweight 550 g design. The low profile allows easier installation in compact cases and reduces interference with memory modules or motherboard components compared with taller tower coolers.

Suitable for

• Small form factor (SFF) desktop builds where cooler height is limited
• Mid-range CPUs requiring up to 165 W thermal dissipation
• Systems where quieter operation is preferred over maximum overclocking headroom
• Upgrades from stock coolers to improve temperature control and acoustics

How to use

Install the cooler following the motherboard and case manufacturer instructions: mount the supplied backplate or retention brackets compatible with the chosen socket, apply a thin, even layer of thermal paste to the CPU heatspreader, position the heatsink over the socket and secure it with the provided screws or clips. Connect the 4-pin PWM fan connector to the CPU_FAN or AIO_PUMP header on the motherboard to enable automatic speed control. Ensure sufficient clearance around memory modules and case components before finalizing installation.

Recommendations

For best results, use a quality thermal paste and set the motherboard fan curve to balance noise and cooling performance. Periodically clean dust from the fan and fin stack to maintain airflow. The VIPER H6L is suited to systems prioritizing compact size and lower noise; consider case airflow improvements if you pair it with high-TDP processors under sustained load.
