darkFlash DG240 All-in-one Liquid CPU Cooler - Quiet High-Flow 240mm

In this review the darkFlash DG240 AIO cooler is evaluated for gamers and content creators who need effective CPU thermal management without excessive noise. The bottom line: this 240mm cooler pairs a high-speed, durable pump with PWM-controlled ARGB fans to deliver strong airflow and adaptive cooling while remaining relatively quiet, making it a practical choice for single-CPU gaming rigs and mid-tower builds where a balance of performance and aesthetics matters.

Key Features

• High-speed pump: A 3-phase 6-pole motor runs up to 3000 RPM to handle up to 315W TDP, providing reliable heat transfer under heavy CPU loads.
• Ceramic bearing: The pump uses a ceramic bearing for improved durability and resistance to heat and wear over long-term use.
• Efficient fans: Fans deliver up to 81.5 CFM at about 33 dBA and use PWM control to scale cooling with system load for quieter idle operation.
• ARGB sync: The pump head and fans support 5V 3-pin ARGB sync so lighting can be unified through compatible ASUS, Gigabyte, or MSI motherboards.
• Long, protected tubing: A 400mm high polymer rubber hose offers low resistance and flexible routing for varied case layouts while resisting abrasion.
• Included mounting: The kit provides mounting plates and fasteners compatible with Intel and AMD sockets for straightforward installation.

Who It's For

The DG240 is aimed at PC builders who want an all-in-one 240mm liquid cooler that balances raw cooling capacity with low noise and visual customization. It fits gamers running mid-range to high-end CPUs, streamers, and creators who push sustained loads and need a pump rated to handle higher wattage.

Those who should look elsewhere include users who require extreme overclocking headroom beyond the stated 315W TDP, or buyers who need a larger radiator footprint for maximum thermal margin; a 240mm radiator will be limited compared with 280mm or 360mm solutions.

Pros & Cons

Pros

• Strong pump performance with a 3-phase motor and ceramic bearing for longevity.
• Fans provide high airflow with PWM control to keep noise near 33 dBA under moderate loads.
• ARGB lighting supports motherboard sync for coordinated system aesthetics.
• 400mm tubing and protective hoses simplify installation in diverse case layouts.

Cons

• As a 240mm AIO, it can be less effective than larger radiators for extreme overclocking.
• ARGB requires a 5V 3-pin header on the motherboard for full lighting control.

Specifications
