Water block EK Water Blocks 3831109819265

The EK Water Blocks 3831109819265 is the EK-Quantum Magnitude CPU water block engineered for AMD Socket AM4 processors. CNC-machined from solid materials, this high-performance block combines a nickel-plated copper cold plate and a glass-like cast acrylic top to provide efficient heat transfer and robust durability. The AM4-specific flow distribution insert and cold plate geometry are tailored to the IHS and chiplet layout of Ryzen CPUs, optimizing coolant flow where it is most needed while maintaining low flow restriction.

Advantages

The Magnitude design increases cooling surface area through a CNC-machined brass insert and an enlarged fin array, offering substantially improved thermal performance in a compact footprint suitable for compact builds. Its nickel-plated copper cold plate uses 0.40 mm microchannels and 0.26 mm microfins to maximize thermal transfer with minimal pressure drop. The product includes an addressable D-RGB LED strip under a translucent top and an integrated H-shaped mounting frame that provides secure, precise mounting pressure and a distinctive aesthetic.

Suitable for

• Custom water-cooling loops built around AMD AM4 socket processors (Ryzen)
• High-performance gaming PCs requiring low CPU temperatures under load
• Workstations running sustained heavy CPU workloads or content creation tasks
• Small form factor (mITX/mATX) systems where compact, high-efficiency cooling is required

• Mounting: integrated three-dimensional H-shaped aluminum mounting frame for precise pressure and screw integration

How to use

Mount the EK-Quantum Magnitude onto an AM4 socket following the manufacturer’s installation instructions and torque recommendations to ensure correct contact with the CPU IHS. Apply a thin, even layer of thermal paste to the CPU before placing the block. Connect the water block to your custom loop using compatible fittings and ensure flow direction matches your loop planning. Attach the 3-pin 5V D-RGB cable to a compatible controller or motherboard header for lighting control. After installation, pressure-test and leak-test the loop before powering the system to confirm proper sealing and coolant circulation.

Usage recommendations

For optimal thermal contact, verify the CPU IHS curvature. If the IHS is significantly concave or lapped, consider using the optional flat cold plate variants or the supplied thicker jet plate to adjust cold plate curvature. Use high-quality compatible fittings and avoid excessive flow restriction elsewhere in the loop to take full advantage of the Magnitude’s low flow resistance design. Follow safe handling when connecting the D-RGB cable and ensure the loop is leak-tested before normal operation.
