Installing this, the pump is dead quiet, and using the same fans (Phanteks T30) and same thermal paste across all of them, this runs about 5c cooler than the EK coolers. It could be the large difference is due to the pumps, which seem to have been defective. Either way, this cooler is dead silent and cools well. You don't have to use all of the RGB nonsense it comes with and deal with a big nest of cables, either. If you just want to install the cooler without fan RGB it's just the PWM pump header and the fan header on the mobo. You can plug the pump head in to any 2nd gen RGB plug on the motherboard, too. It's a very clean install overall. ## Features - Cool for R9|i7: Patented Next Gen Dual Chamber enhances water pressure and optimizes flow directly to the CPU hotspot, for AMD R9 and Intel i7. - Personalizable Top Cover: Customize the pump top cover with your own 3D designs, giving you creative freedom over the aRGB Gen 2 lighting. - Fine Tuned Performance: Precision-engineered ultra-thin spade fins optimize microchannels for targeted heat dissipation. - Sickleflow 120 Edge: Pre-installed SickleFlow Edge fans deliver premium airflow with optimized PWM blades, while simplifying the installation. - Simplify Brackets: Redesigned brackets simplify installation on AM5 and LGA 1851|1700 platforms. - Going Green Construction: Leading the Going Green initiative, 35% of the cooler's metal is recyclable, the pump top cover is made from recycled plastic, and packaging is reduced by 30%. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CK564T94 | | Air Flow Capacity | 70.7 Cubic Feet Per Minute | | Best Sellers Rank | #302 in Water Cooling Systems | | Brand | Cooler Master | | Brand Name | Cooler Master | | Compatible Devices | Desktop | | Cooling Method | Water | | Customer Reviews | 4.6 out of 5 stars 135 Reviews | | Included Components | 240 Atmos, Install Kits, Controller, Manaual | | Item Dimensions L x W x H | 10.91"L x 4.71"W x 1.07"H | | Item Weight | 3.19 Pounds | | Manufacturer | Cooler Master | | Material Type | Aluminum, Copper, Plastic | | Maximum Rotational Speed | 2500 RPM | | Model | MLX-D24M-A25PZ-R1 | | Noise Level | 25 Decibels | | Number of Items | 1 | | Part Number | MLX-D24M-A25PZ-R1 | | Power Connector Type | 3-Pin | | Product Dimensions | 10.91"L x 4.71"W x 1.07"H | | UPC | 884102112263 | | Unit Count | 1.0 Count | | Warranty Description | 5 Year | ## Product Details - **Air Flow Capacity:** 70.7 Cubic Feet Per Minute - **Brand:** Cooler Master - **Compatible Devices:** Desktop - **Cooling Method:** Water - **Material:** Aluminum, Copper, Plastic - **Maximum Rotational Speed:** 2500 RPM - **Noise Level:** 25 Decibels - **Power Connector Type:** 3-Pin - **Product Dimensions:** 10.91"L x 4.71"W x 1.07"H - **UPC:** 884102112263 ## Images ![Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Image 1](https://m.media-amazon.com/images/I/71+YWYT494L.jpg) ![Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Image 2](https://m.media-amazon.com/images/I/71eUa1l16rL.jpg) ![Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Image 3](https://m.media-amazon.com/images/I/81wS8nZ+O9L.jpg) ![Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Image 4](https://m.media-amazon.com/images/I/71sHaQmnQRL.jpg) ![Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Image 5](https://m.media-amazon.com/images/I/71L6FE4iUqL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works cool, fits to sff cases easily, very silent. *by M***U on February 16, 2026* the best sff aio for a reason. tubes are very soft and very easy to manage them. it fits to every 240mm aio compatible case easily. temps are extremely good for 7800x3d in ssupd meshroom d case . it's very powerful and very silent.... extremely recommended .

The packaging was easy to work through, and durable enough that I'm holding on to it should I ever uninstall this AIO. I put some Noctua fans on it, and it cools my 7800x3D excellently. Installation was pretty straightforward, there weren't a crazy number of cables to manage, and the tubes are flexible enough without feeling too Pinner. The RGB effect is pretty great as well. I would definitely recommend this cooler. ## Frequently Bought Together - Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform - Noctua NF-A12x15 PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (120x15mm, Black) - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
