Product details


The Sigma 540 Air CPU cooler from GameMax is a new and redefined CPU Air cooler which offers a superb cooling performance of 200W TDP and a virtually silent operation, the Sigma is perfect for overclocked systems and the most demanding workstations.

The small upgrades that we have made to the Sigma 540 raises the bar and takes the performance to the highest level when it comes to four heat-pipe CPU coolers.
The four 6-millimeter-thick high-performance heat-pipes with a nickel-plated finish are closely fitted between the radiator and CPU, absorbs the heat directly from the processor. The design of the heatsink is made with a larger surface area compared to other GameMax models this is one of the latest innovations used on the Sigma to provide a stronger and improved thermal dissipation. Overall, the Sigma provides the precise combination of air flow and heatsink.
The aluminium top cover with the GameMax brand logo stamped on adds a sleek look to this innovative, refined and sophisticated CPU cooler.
Includes a 130mm black fan with PWM functionality and featuring nine fan blades and a durable fluid dynamic bearing motor. With a strong airflow of 81.0 CFM and even with its very good cooling capacity of 200 Watts TDP, the fan is a quiet one with the noise level going as low as 18 dBA.
Upgraded metal mounting kits ensure a simple and safe installation with support for the latest Intel & AMD mainstream platforms.

Key Features

  • Top Performing CPU – The Sigma 540 is a high-performance CPU cooler built with an impressive rating of 200W TDP and with no compromise on silence or performance for overclocked systems and the most demanding graphics applications. Efficiently dissipating 200W of heat achieves low temperatures even when the CPU is at the top of its game.
  • 130mm PWM Black Fan Included – One unique 130mm cooling fan is included with a nine-fin fan design delivering huge airflow potential at 81.0 CFM at 1600 RPM and the noise level going as low as 18 dBA for an ultra-silent cooling performance. Adjust fan speeds to accommodate the demands of your system.
  • Anti-Vibration Pads – The 130mm cooling fan is equipped with four anti-vibration pads that effectively reduce the vibration and noise generated by the radiator during operation.
  • 4 x 6mm Heat Pipes – Including 4 x 6mm direct contact heat pipes made of copper to accelerate the heat conduction through the entire heat pipes. This guarantees heat to be transferred quickly and efficiently throughout the aluminium heatsink.
  • Aluminium Heatsink – The heatsink is made using 56 pieces of aluminium fins and built with optimised fin stacked distance between each layer. It equates to 6600cm squared thermal surface area which compared to its predecessors is a 30 percent increase providing a stronger heat dissipation.
  • Intel Compatibility – Capable of handling intel high-end CPUs (Intel 13th Gen) Intel Socket LGA115X Intel LGA1200 / Intel LGA1700.
  • AMD Compatibility – Capable of handling AMD high-end CPUs (AM5) AMD Socket AM4 / AM5.
