Who it fits

Key specs explained

D5 pump

This unit uses a genuine D5 pump, which is a standard component in custom loops. It provides reliable pressure to move coolant through your system. You get consistent flow without needing high voltage. This pump type is known for durability and quiet operation. It suits builders who want a proven, high-performance core for their loop rather than experimental alternatives.

9 G1/4" ports

The reservoir includes nine connection points for tubing. This allows you to route multiple lines easily without complex adapters. You can connect your CPU block, GPU block, and radiators directly. This reduces the need for additional fittings or elbows. It makes building and maintaining your loop simpler and more organized compared to units with fewer ports.

1000 liters per hour flow rate

This spec indicates the maximum volume of coolant the pump can move. A rate of 1000 L/h ensures strong circulation through your components. It helps maintain stable temperatures under load. You benefit from efficient heat transfer across your entire system. This flow rate is sufficient for most standard custom loop configurations with multiple blocks.

200ml capacity

The reservoir holds approximately 200 milliliters of coolant. This volume provides a buffer for thermal expansion and air bubbles. It allows you to see the coolant level clearly. You can monitor for leaks or low levels easily. This size is compact yet functional, fitting well in standard cases while providing enough volume for stable loop performance.

Materials and Physical Layout

The listing describes the reservoir body as made from acrylic and plexi. This material choice gives you a clear view of the coolant level and flow. You can see the liquid inside without guessing. The cap is also part of this transparent assembly. This allows you to monitor your system status at a glance.

According to the listing, the physical dimensions are 146.5 by 143.5 by 86 mm. In inches, that is roughly 5.77 by 5.65 by 5.77 inches. You need to check your case space before buying. This size is compact but not tiny. It fits in most mid-tower and full-tower cases. You should verify clearance around the mounting area. The unit weighs nothing extra beyond the materials listed.

The layout includes nine G1/4" ports on the reservoir. This gives you many options for tubing connections. You can route lines in different directions easily. The pump is a genuine D5 model. It sits inside the reservoir. The combination keeps the pump submerged for cooling. This design helps with noise reduction. You get a quiet operation from the start. The finish is smooth and clear. It looks clean in a build. You do not need to add extra covers. The design is ready for immediate installation.

Setup and Daily Use Guide

Installing this pump and reservoir combo requires careful planning due to its specific dimensions. The unit measures 146.5 by 143.5 by 86 millimeters. You need to ensure your case or mounting area has enough clearance for this footprint. The physical layout includes nine G1/4" ports on the reservoir. This high port count allows you to route multiple tubes directly without needing extra adapters. It simplifies the initial plumbing phase by giving you flexible connection points.

The system relies on a genuine D5 pump. You must connect the pump to a PWM header on your motherboard or a dedicated fan controller. This connection lets you adjust the speed based on your cooling needs. The pump is rated for 1000 liters per hour with a maximum head pressure of 5.2 meters. These specs mean it can push coolant through long loops or multiple radiators without losing significant flow. You do not need to worry about weak circulation in complex setups.

For daily use, the acrylic body provides a clear view of the coolant level. You can monitor the fill status easily. The D-RGB lighting adds visual appeal to your build. You sync these lights with your motherboard software for unified aesthetics. The 200ml capacity is sufficient for most standard custom loops. It holds enough liquid to prevent air pockets while remaining compact. This combination of reliable pumping power and straightforward connectivity makes it a practical choice for builders who want a dependable core for their loop.

Before You Buy This Pump

You need to verify case compatibility before purchasing. The unit measures 146.5 by 143.5 by 86 millimeters. Ensure your chassis has sufficient clearance for this footprint. You must also confirm your motherboard supports D-RGB lighting. This model uses D-RGB, not standard 5V RGB. Check your controller or software for proper protocol support. You will need G1/4" tubing and fittings for the nine ports. Plan your routing carefully to avoid kinks. This pump is designed for custom loops, not AIOs. It pairs well with other EK Quantum components. You should consider adding a flow meter if you want precise monitoring. Regular maintenance includes checking for leaks and cleaning the reservoir. This setup requires more effort than pre-filled AIOs. It suits builders who want full control over loop performance. You gain flexibility in pump placement and reservoir size. The D5 pump offers reliable pressure for complex tubing runs. Just ensure you have the right tools and patience for assembly.

Check before you buy

• Verify case clearance for 146.5 x 143.5 x 86mm dimensions
• Confirm motherboard supports D-RGB lighting protocols
• Ensure you have G1/4" tubing and fittings ready
• Check compatibility with your existing EK Quantum components
