The Story
DeepCool LM240 ARGB 240mm AiO CPU Liquid Cooler White R-LM240-WHDMMC-1
The LM series brings a fresh update to liquid cooling with a compact 2.4" IPS display that now supports MP4 video playback for a more dynamic screen experience. Cooling performance is refined with an upgraded pump for better efficiency and quieter operation.
Features:
- Control the speed and lighting of both the pump and fans precisely using PWM connectivity for optimal performance.
- Experience exceptional heat transfer capabilities due to the large surface area provided.
- Achieve powerful airflow (66.23 CFM) and significant static pressure (3.27 mmAq) to force air through dense radiator fins effectively.
- Customise your system’s appearance completely with addressable RGB lighting that connects via the standard 3-pin (+5V-D-G) header.
- Maintain system quietness where possible, with fan noise kept below 36.07 dB(A) even at maximum rotational speed.

CLEANLY FOCUSED 2.4" LCD
See more from any angle with the 2.4" IPS display. A 320×240 resolution ensures crisp visuals, while enhanced color accuracy and screen stability deliver consistent clarity throughout. The soft perimeter lighting adding structured contrast to the minimal design.
DeepCreative: THE CONTROL CENTER
Take full control of your LM cooler with DeepCreative software. Monitor essential system information in real time, personalize the screen display, or switch to Zen Mode for a distraction-free experience when performance matters most. Screen brightness and display orientation can also be adjusted to suit your setup.
GEN 6 WATER PUMP WITH PWM CONTROL
The LM240 WH features DeepCool's newly developed 6th-generation pump, engineered for greater thermal efficiency and quieter performance on today's high-end CPUs. A 3-phase, 6-slot, 4-pole motor with FOC control powers the pump from 2,500 to 3,400 RPM with precision and stability.
EFFICIENCY IN MOTION
Equipped with a long-life hydro bearing, the included FL12 SE fans delivering steady airflow and reliable cooling over long-term use. Distinctive lighting effects bring vivid colors to every edge, working in harmony with your system’s lighting setup.
ANTI-LEAK TECHNOLOGY
DeepCool’s patented Anti-Leak Technology helps maintain internal pressure balance within the liquid cooling system. A built-in valve releases excess pressure once it exceeds ambient levels, reducing the risk of leakage and improving long-term operational stability.
SIMPLIFIED INSTALLATION
The included mounting hardware provides an easy installation process that ensures proper contact and equal pressure on both Intel and AMD platforms. Everything needed to mount the LM240 WH to the latest mainstream CPUs is included in the box, so you are ready to go.
