Corsair Hydro X Component Comparison
Physical Dimensions
The Corsair Hydro X XM2 M.2 SSD Water Block is designed to fit compactly on your drive, measuring 6.3 inches in length, 0.35 inches in width, and 0.35 inches in height. In contrast, the Corsair Hydro X XR5 280mm Radiator is a much larger component, with a length of 12.2 inches, a width of 5.51 inches, and a height of 1.18 inches. You need to account for these significant size differences when planning your case layout. The radiator requires ample space for airflow, while the water block is slim enough to sit directly on the M.2 slot without obstructing nearby components like RAM or the motherboard VRMs.
Weight and Mass
Weight distribution matters for motherboard stability. The XM2 M.2 Water Block is extremely light, weighing only 1.8 ounces. This minimal mass places negligible stress on your M.2 slot or the motherboard PCB. The XR5 280mm Radiator is substantially heavier at 1.46 pounds due to its dense copper core and fin stack. While this weight is normal for a radiator of this size, you should ensure your case has adequate mounting points to support it securely. The lightness of the water block makes it easier to handle during installation without worrying about bending the board.
Construction Material
Both products share a premium copper construction, which is essential for effective heat transfer in custom loops. The XM2 block uses a high-performance copper cold plate to draw heat directly from your SSD. Similarly, the XR5 radiator features a premium copper core with 25-micron thick cooling fins. This shared material choice ensures compatibility and optimized thermal performance between the two components when used together. Copper provides excellent thermal conductivity, allowing heat to move efficiently from the SSD to the block, and from the water to the radiator fins for dissipation into the air.
Fan Compatibility
The XR5 280mm Radiator is designed with dual 140mm fan mounts on either side, offering flexibility for your airflow setup. It includes integrated fan screw guides to simplify the mounting process, ensuring your fans are aligned correctly. The XM2 M.2 Water Block does not have any fan mounts, as it is a passive component that relies on the loop's coolant flow and the radiator's fans for cooling. If you need active cooling surfaces, the radiator is the only option here, providing dedicated mounting points for high-airflow or low-noise fans.
Installation Interface
The XM2 block installs directly onto compatible 2280 M.2 SSDs, connecting to your loop via two standard G1/4” thread connector fittings, which are not included. This makes it a straightforward add-on for existing builds. The XR5 radiator requires mounting to your case or bracket, utilizing its dual 140mm fan mounts. While the radiator features integrated screw guides for ease of use, the water block’s interface is specific to the M.2 form factor. You will need to manage tubing connections for the block separately from the radiator’s structural installation.
Choose Your Corsair Hydro X Part
You want to cool an M.2 SSD in your loop
This block is designed to mount directly onto compatible 2280 M.2 SSDs. Its copper cold plate draws heat away from the drive to reduce thermal throttling. It connects to your custom loop using standard G1/4” fittings. This component helps maintain lower drive temperatures during heavy workloads.
You need a radiator to dissipate heat from the loop
This 280 mm radiator features dual 140mm fan mounts for high airflow. Its premium copper core and 25 micron thick fins provide high thermal transfer rates. The 30 mm thickness allows for easy installation. Integrated screw guides simplify mounting fans. This part is essential for rejecting heat in your custom cooling setup.
You are building a complete custom loop and need both
A complete loop requires both a heat exchanger and component blocks. While the XR5 radiator handles the bulk of heat rejection with its large surface area, you will also need the XM2 M.2 block to cool your storage. The XR5 ensures the loop runs efficiently, while the block protects your SSD.
