ID-COOLING DX240 MAX Liquid CPU Cooler 240mm - Extreme Cooling

In this review the ID-COOLING DX240 MAX is evaluated as a mid-sized AIO aimed at gamers and high-performance builders who need effective heat control without a bulky radiator. The main reason to consider the DX240 MAX is its emphasis on raw cooling surface area: a 38mm thick radiator increases cooling area by about 40%, which translates into lower sustained CPU temperatures under load. The unit pairs that radiator with a GEN 7 pump and two high-airflow 120mm fans to tackle TDPs up to 300W, making it a straightforward choice for overclocked mainstream systems.

Key Features

• 38mm Thick Radiator: The expanded fin stack increases cooling surface by roughly 40%, which helps dissipate heat more effectively than standard 25mm radiators.
• GEN 7 Pump: A pump running at up to 2900 RPM provides strong coolant circulation to maintain stable temperatures for extended workloads.
• Two 120mm High-efficiency Fans: Fans deliver high airflow and pressure, supporting rapid heat transfer from radiator fins during sustained loads.
• Zero RPM Support: PWM control allows the fans to stop at low temperatures, eliminating fan noise when the system is idle or lightly loaded.
• ARGB Pump Cover: The illuminated pump cover adds visual flair with a fluid, stream-like lighting effect for users who want aesthetics as well as performance.
• Simple Cable Management: Daisy chain fan connectors reduce cable clutter and make installation cleaner in modern builds.

Who It's For

The DX240 MAX is best for PC builders with mid-tower or larger cases who want a reliable 240mm AIO that edges toward higher cooling capacity without moving to a 360mm radiator. It suits gamers, content creators, and overclockers running CPUs with a TDP up to 300W who need improved heat dissipation from a thicker fin stack.

Users who need whisper-quiet operation at all times or who plan extreme multi-core overclocks beyond the cooler's 300W rating should look at larger radiators or custom loops. Also double-check case clearance, since the thicker 38mm radiator requires extra space compared with standard slim radiators.

Pros & Cons

Pros

• Strong thermal performance from the thick 38mm radiator and aggressive fin density.
• High-flow pump and efficient 120mm fans keep temperatures under control during sustained loads.
• Zero RPM fan support and daisy chain connectors simplify wiring and reduce idle noise in many scenarios.
• ARGB pump cover adds attractive lighting for systems with a windowed case.

Cons

• The pump has been reported as noticeably noisy by some users, so it may be audible under certain conditions.
• The thicker radiator needs extra clearance and may not fit every small mid-tower without checking measurements first.

Our Verdict

The DX240 MAX is a solid 240mm AIO for builders who want better-than-average cooling without upgrading to a larger radiator; its thickened 38mm radiator and GEN 7 pump offer tangible temperature control for CPUs up to 300W. It represents good value for mainstream overclocking and high-load gaming rigs, though buyers sensitive to pump noise or limited by case clearance should verify fit and tolerance before purchase.

Frequently Asked Questions

Will this cooler fit in a standard mid-tower case?
It fits most mid-tower cases that support 240mm radiators, but you must allow extra clearance for the 38mm thickness and check space above or in front of the case where the radiator will mount.

How loud is the cooler in real use?
Fans can enter zero RPM mode at low load for silent idle, but some users report the pump can be noticeably audible under load; noise level varies by system and mounting.

Which sockets are supported?
The cooler supports common Intel sockets including LGA1851/1700/1200/115X and AMD AM5/AM4, making it compatible with most current mainstream platforms.
