CPU cooler Gamemax Sigma 620 LCD Black ARGB CPU Cooler

Gamemax Sigma 620 LCD Black ARGB is an air CPU cooler, aimed at mid-range and more serious gaming/workstations, where you want stable temperatures and a bit of visual effect. Rely on two 120 mm fans with 5V ARGB backlighting and a standard 4 PIN connector for PWM control. Wide compatibility with sockets like AM4, AM5 and LGA 1700 allows you to use it on most current platforms. This is a variant that combines effective airflow and controlled RPM for balanced cooling.

What you get

With two 120 x 120 x 25 mm fans, this cooler can push up to 142.37 CFM air, which is a serious airflow for air cooling and is suitable for more loaded CPU configurations. The range from 800 to 1800 RPM gives you flexibility – you can keep lower RPM for quieter work in idle and raise to maximum at serious load. Maximum static pressure of 2.54 mmH2O helps air pass effectively through dense radiator fins. The ARGB connector (5V) allows you to synchronize the backlight with the rest of the components, and 4 PIN PWM control gives smooth fan control according to temperatures.

• Air cooling – easy maintenance option without liquids and pumps, suitable for long-term daily use.
• Compatibility with sockets AM4, AM5, LGA 1200, LGA 115x, LGA 1700, LGA 1851 – you can use it with both modern Intel and AMD platforms, without changing the cooler on upgrade.
• Two 120 mm fans (120 x 120 x 25 mm) – larger radiator coverage and better hot air dissipation compared to a single fan.
• Speed 800–1800 RPM – allows balance between quiet work at low load and more aggressive cooling at high temperatures.
• Airflow 142.37 CFM – high air throughput, suitable for more powerful CPUs and cases with more limited airflow.
• Static pressure 2.54 mmH2O – better efficiency when blowing through the radiator, which helps with higher thermal load.
• Noise level up to 42 dBA – expected more serious audibility at maximum RPM, but in exchange you get more aggressive cooling.
• 4 PIN + 5V ARGB connectors – full control from the motherboard: PWM for RPM and ARGB for synchronized backlight with the rest of the components.

Who is it suitable for

It is suitable if you are building a gaming or work computer on a current Intel or AMD platform and are looking for an air cooler with good airflow and ARGB look. It fits builds where you want a visible cooler with backlight and are OK with the fact that at maximum RPM the noise reaches up to 42 dBA. If you are chasing an absolutely silent machine or extreme overclocking, you can also look at quieter or more massive solutions.

The most sensible thing in Gamemax Sigma 620 LCD Black ARGB is the combination of strong airflow, two 120 mm fans and wide socket compatibility, plus 5V ARGB to visually fit the cooler into the whole build.
