Who it fits
Good fit for
You should consider this pump if you are building in a small form factor case. The 43ML integrated tank reduces the need for a separate reservoir. The compact size fits tight spaces better than larger combos. The digital display helps you monitor system health without extra hardware. It suits users who want a simple, all-in-one pump and reservoir solution for DDC setups.
Who should skip it
Skip this option if you need a large water volume for thermal buffering. The 43ML tank is small and holds less coolant than standard reservoirs. You might prefer a dedicated reservoir if you plan to add many components. The display is small, so reading details from a distance may be hard. If you need high flow for complex loops, verify the 700 L/H rate meets your needs.
Verdict: This pump combo is a practical choice for small builds requiring compact cooling components. It offers essential monitoring and flexible control in a minimal footprint.
Key Specs Explained
Pump Speed: 1800-4800RPM
This range lets you balance noise and flow. Lower speeds keep builds quiet, while higher speeds push more coolant. You can adjust this using PWM or manual controls. This flexibility suits users who need silent operation during idle time and maximum cooling performance during heavy loads. It ensures you can tune the pump to your specific case size and noise tolerance.
Display Size: 2-inch
A two-inch digital screen shows real-time data like speed, flow, voltage, and load. You can monitor system health without opening your case or using software. This visibility helps you verify that the pump is running correctly. It is useful for troubleshooting leaks or flow issues quickly. The display provides immediate feedback on your cooling loop status.
Max Flow Lift: 6 Meters
This spec indicates the vertical height the pump can push water. A six-meter lift handles most standard custom loop configurations. You do not need to worry about gravity fighting the pump in typical cases. This capability ensures reliable flow even if your reservoir is positioned above the radiator. It provides a safety margin for complex tubing routes.
Flow Rate: 700L/H
This value shows the volume of coolant moved per hour. Seven hundred liters per hour offers strong circulation for standard water blocks. It helps maintain consistent temperatures across your CPU and GPU. This rate is sufficient for most air-cooled and liquid-cooled components. You get reliable heat transfer without excessive noise from high flow speeds.
Integrated Tank: 43ML
The pump module includes a small forty-three milliliter water tank. This design saves space in compact cases while holding enough coolant to prevent air bubbles. It simplifies installation by combining the pump and reservoir. You avoid buying separate components, reducing potential leak points. This integration is ideal for small form factor builds where space is limited.
Compact Design and Controls
According to the listing, this unit features a black finish and measures GFMB-100. The design integrates a DDC pump with a 43ml water tank. This small reservoir volume improves compatibility with compact chassis. You save space without sacrificing pump performance. The layout allows expansion by adding a separate cylinder tank. This flexibility supports various water storage schemes. You can choose the setup that fits your case dimensions.
The front includes a 2-inch digital display. It shows speed, flow, voltage, and load in real time. You get immediate feedback on system status without opening your case. This visibility helps you monitor performance during adjustments. The display is embedded directly into the pump module. This keeps the design clean and functional.
Control options include PWM and manual speed adjustment. You can set the pump speed between 1800 and 4800 RPM. This range lets you balance noise levels against flow rate. The unit uses a 4-pin Molex D port for power. It also provides a PWM signal output. These connections ensure compatibility with standard water-cooled products. You can integrate this combo into existing loops easily. The practical design focuses on fit and function rather than aesthetics.
Setup And Daily Use Guide
Setting up this Granzon DDC pump combo requires attention to its power connections. The unit includes a 4-pin Molex port for power and a separate D port for the PWM signal. You must connect these to compatible motherboard headers or external controllers. This dual-port design ensures the pump receives stable voltage while allowing precise speed adjustments via PWM or manual controls. The integration of a 43ml water tank simplifies initial filling. You can fill the system directly through this small reservoir or expand to a larger cylinder tank if your chassis allows. This flexibility helps you manage coolant volume without complex plumbing modifications.
During daily use, the 2-inch digital display provides continuous feedback. It shows real-time data on speed, flow rate, voltage, and load. This visibility lets you verify that the pump is operating within the 1800 to 4800 RPM range. You can adjust the speed to balance noise levels against cooling performance. The maximum flow lift of 6 meters and 700L/h flow rate indicate strong performance for standard loop configurations. The unit is compatible with various water-cooled products, making it suitable for custom loops in compact cases. The black finish blends well with most internal components. You do not need additional software to monitor the display, as all critical metrics appear directly on the hardware. This straightforward interface reduces the need for third-party monitoring tools during routine checks.
Before You Buy This Combo
You need to verify your chassis has space for the GFMB-100 form factor. The 43ml integrated tank is small. You might need a larger external reservoir if your loop requires more coolant volume or easier bleeding. Check your motherboard headers carefully. This unit uses a 4-pin Molex for power and a separate D port for the PWM signal. Not all boards support this specific split connection. Ensure you have the necessary cables or adapters. Upkeep is straightforward since there are no moving parts in the display. You only need to check for leaks during the initial fill. This product suits builders who prioritize compactness and real-time data. It fits well alongside standard AIOs if you need a custom loop in a small case. However, if you prefer silent operation at all times, note that the lowest speed is 1800 RPM. This may still produce audible noise in very quiet environments. Consider your case size and noise tolerance before purchasing.
Check before you buy
- Verify chassis compatibility with the GFMB-100 size.
- Check for separate Molex and D port headers.
- Confirm if 43ml tank volume meets your loop needs.
- Ensure you can manage 1800 RPM noise levels.
