The PRIME LC 240 ARGB is a closed-loop liquid CPU cooling system intended for desktop PC builds where both cooling performance and coordinated ARGB lighting are required. Its CPU block uses a copper contact plate with precision micro-channels to improve heat transfer from the processor into the cooling loop. ASUS also specifies a three-phase, six-slot pump motor, a ceramic bearing system, and a PPS pump housing.
The radiator measures 277 × 120 × 27 mm and is connected to the CPU block with 400 mm sleeved rubber tubing, providing flexibility when positioning the radiator inside the chassis. The cooler comes with two pre-installed 120 mm PRIME LC 24025 integrated fans.
The water block features customizable infinity-mirror lenses, while the fans and block support ARGB lighting through ASUS Aura Sync. ASUS has also integrated the fan and lighting connections to simplify cable management.

CPU contact plate:
The cooler uses a high-purity copper plate with micro-channel construction. The enlarged contact area is designed to improve heat transfer between the CPU and the cooling system.
Pump:
ASUS specifies a three-phase, six-slot motor together with a ceramic bearing system and PPS pump housing. The design is intended to provide stable coolant circulation while maintaining the compact water-block format.
Radiator:
The radiator measures 277 × 120 × 27 mm, with 400 mm of sleeved rubber tubing connecting it to the water block.
Fans:
Two PRIME LC 24025 Integrated Fans are supplied and pre-installed. They operate from 600 to 2200 RPM ±10%, with up to 75.7 CFM airflow and 3.2 mmH₂O static pressure. ASUS specifies a maximum acoustic level of 34 dB(A).
The water block incorporates a customizable infinity-mirror lens, creating a layered illuminated effect when the ARGB lighting is active. The included fans are also ARGB-equipped and come pre-installed on the radiator.
The cooler supports ASUS Aura Sync, allowing its lighting to be synchronized with compatible ASUS components and other Aura Sync-compatible hardware. ASUS also uses an integrated fan/ARGB connection arrangement to reduce cable clutter during installation.
