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.
