ASUS ROG Strix LC II 240 AIO Liquid CPU Cooler - High-Performance RGB

Our review of the ASUS ROG Strix LC II 240 finds it ideal for PC builders who want a balance of strong cooling performance and striking RGB aesthetics. The unit uses a seventh gen Asetek pump that runs quietly at low speeds yet provides dependable thermal headroom, and ROG-designed radiator fans boost airflow and static pressure for sustained cooling under load. With reinforced sleeved tubing and addressable RGB on the pump, the Strix LC II 240 is aimed at enthusiasts who want reliable liquid cooling that also complements an ROG-styled build.

Key Features

• Seventh Gen Asetek Pump: Delivers efficient heat transfer with an operating range starting at 840 rpm to keep noise low while maintaining strong cooling performance.
• ROG-Designed Radiator Fans: Optimized for both airflow and static pressure to move air across the 240mm radiator and lower CPU temperatures under sustained load.
• Individually Addressable RGB: Customizable lighting on the pump head provides vivid multi-color effects to match motherboard RGB or a themed build.
• Reinforced Sleeved Tubing: Durable, braided tubing resists kinks and wear over time, making the closed-loop system easier to route during installation.
• Wide Socket Support: Compatible with modern Intel and AMD sockets so it fits many gaming and productivity builds without extra adapters.

Who It's For

The Strix LC II 240 is well suited to PC enthusiasts and gamers who prioritize a clean look with integrated RGB and reliable all-in-one liquid cooling for mainstream and high-end CPUs. Builders using ROG motherboards will appreciate how the lighting and styling complement an ASUS ecosystem.

It may be less appropriate for users who need extreme cooling for heavy overclocking on very large Threadripper-class dies or who prefer a passive, fanless solution. If ultra-low noise is the single highest priority, results vary among users and a custom loop or very large air cooler might be preferable.

Pros & Cons

Pros

Cons

• Noise reports are mixed; some users find it very quiet while others note audible fan or pump noise under certain conditions.
• 240mm radiator size may limit compatibility in smaller cases or when maximum cooling headroom is required.
