240 mm ARGB liquid cooler

The Antec Ultra 240 ARGB is a closed-loop liquid cooler built for modern desktop CPUs. It includes a mirror-finish pump head that produces layered lighting effects alongside two 120 mm ARGB PWM radiator fans. The unit targets enthusiasts who want strong thermal performance with addressable RGB aesthetics. It fits mainstream Intel and AMD platforms using a single mounting kit.

PWM control and noise limits

Fan speed is governed by PWM signalling so the system can balance airflow against acoustic output. The pump runs at 2600 RPM while keeping noise below 23 dB(A) under typical load. Radiator fans reach 33.05 dB(A) at maximum speed, which defines the practical ceiling for quiet operation. Builders needing silent idle behaviour should verify case airflow can dissipate heat at lower fan curves.

Copper base and broad socket support

A large copper base plate contacts the CPU heat spreader directly to improve thermal conductivity across the interface. The mounting hardware covers Intel LGA 115X, 1200, 1366, 1700, 1851 and 20XX sockets plus AMD AM4 and AM5. This breadth suits upgraders moving between platforms, but the fixed 240 mm radiator length restricts case compatibility to chassis with suitable top or front mounting points.

Questions about this item

Which socket should I pick for my Intel LGA 1700 or AMD AM5 build?

The cooler includes mounting hardware for Intel LGA 115X, 1200, 1366, 1700, 1851 and AMD AM4, AM5; select the bracket that matches your motherboard socket.

What does the 2600 RPM pump speed mean for daily temperatures?

The pump runs at 2600 RPM while staying below 23 dB(A), providing strong coolant flow that keeps CPU temperatures low under load.

How does the PWM fan interface affect noise at full speed?

PWM control lets the motherboard adjust fan speed automatically; at maximum the fans reach 33.05 dB(A), dropping to near-silent levels when the CPU is cool.
