This low profile helps avoid interference with large CPU coolers. Daily use involves monitoring loop temperature. The copper base transfers heat from the RAM to the coolant. The transparent acrylic top shows the liquid flow. You can choose between black or silvery finishes. The RGB lighting adds visual effect to your build. Ensure all connections are tight to prevent leaks. The system relies on your pump and radiator performance. This cooler does not have its own fan or pump. It depends entirely on your loop components. Check compatibility with your specific RAM height. The compact size allows for dense motherboard layouts. Regular maintenance involves checking coolant levels and clarity. The acrylic top may require gentle cleaning to maintain visibility. This setup is best for enthusiasts who manage their own loops. It is not a plug-and-play solution for air-cooled systems. Verify your tubing fits the G1/4 inch ports. The 5V DC requirement is standard for most RGB headers. Plan your tubing routes carefully to avoid stress on the block.
Before you buy this RAM cooler
This KAGAUOAS block is a dedicated component for custom loops. It does not include a pump, reservoir, or tubing. You must source these separately to build a functional system. The unit supports up to four DIMMs, covering DDR3 and DDR4 modules. Check your motherboard layout to ensure the 5.2-inch length fits without blocking adjacent slots. The 0.55-inch height is low, but verify clearance against your CPU cooler. The G1/4 inch threads require compatible fittings. You will need to mix coolant and maintain the loop to prevent algae or corrosion. This product suits builders who already have a complete loop infrastructure. It is not a standalone solution for air-cooled systems. Consider your existing pump capacity, as the 0.5-watt draw is minor, but the total loop resistance matters. Ensure your tubing inner diameter matches the block’s ports. Proper maintenance keeps the copper heatsink effective. This cooler integrates best into a fully assembled custom loop rather than a simple AIO setup.
Check before you buy
- Verify G1/4 inch fittings match your existing tubing.
- Check motherboard spacing for the 5.2-inch length.
- Confirm clearance with your CPU cooler height.
- Ensure you have a complete custom loop setup.
