Alphacool MC-2 ARGB Black 2 in 1 accessory

What this accessory does

The Alphacool MC-2 ARGB Black is a dual-fan memory cooler that clips directly onto RAM modules to lower temperatures during heavy workloads. It targets enthusiasts and overclockers who need extra thermal headroom for high-frequency memory kits. The unit adds 5 V addressable RGB lighting that synchronises with compatible motherboard software. Builders seeking passive-only cooling or those with extremely low-profile memory should look elsewhere.

Build integration and clearance

The cooler measures 120 x 60 x 25 mm and is designed to sit above the motherboard without clashing with the fins of most standard air coolers. It fits typical four-slot desktop boards and attaches using tool-free clips on each side of the memory stick. A 4-pin PWM header on the motherboard is required for automatic speed control; the fans will not self-regulate without that connection. Systems lacking a spare PWM header or using oversized CPU coolers with tight clearances may not accommodate this accessory.

Thermals noise and power in normal use

Two fans spin up to 3200 RPM ±10 % and move 16.17 CFM across the memory surface, cutting module temperatures under sustained load. At that speed the assembly produces a measured 20.17 dBA, staying barely audible inside a closed case. PWM control keeps the fans quiet at idle and ramps them only when memory temperatures rise during intensive read or write activity.
