Know before you buy
This pump features standard G1/4 threading, which is the industry standard for custom water cooling. This allows you to use almost any G1/4 threaded compression or barb fitting currently on the market.
The MCP655-B uses a standard 4-pin Molex connector for direct power from your power supply. It is a plug-and-play device, meaning it will run at its full rated speed as soon as the system is powered on.
Yes, with a nominal head pressure of approximately 13 feet and a flow rate of 317 GPH, this pump is well-suited for demanding loops. Its high-pressure capability ensures consistent flow even when navigating multiple water blocks and radiators.
The pump is designed for quiet operation, even at high speeds. Because it utilizes a single-moving-part spherical motor design, it minimizes vibration and mechanical noise, making it an excellent choice for silent-focused builds.
This pump has a Mean Time Between Failures (MTBF) of 50,000 hours. The longevity is largely due to its brushless motor design, which features only one moving part to reduce wear and tear over time.
Yes, its compact footprint makes it ideal for tight spaces. However, ensure your case has enough clearance for the G1/4 fittings and tubing runs, as the pump itself is quite space-efficient.
