D5 PWM Pump with Acrylic Top

This 12 V permanent-magnet centrifugal pump delivers 18 W of cooling power for custom water-cooling loops. The acrylic top with a black aluminium-alloy heatsink cover integrates directly into D5-format reservoirs. PWM control lets the loop adjust speed automatically based on system temperature. It suits builders assembling a new open-loop or upgrading an existing D5 reservoir.

4 m Head Pressure and PWM Range

The pump develops up to 4 metres of lift, providing comfortable flow for typical CPU-and-GPU loops with moderate restriction. At higher restriction — dense radiator stacks or many angled fittings — flow will taper off as the curve reaches its limit. The sine-wave drive circuit keeps operation stable across the PWM duty cycle without audible vibration. Headroom is sufficient for most single-loop configurations.

Replaces Fixed-Speed D5 Units

Swapping a fixed-voltage D5 for this PWM model removes the need for a separate fan controller or voltage regulator. The upgrade is worthwhile when the loop already uses a PWM-capable motherboard header or standalone controller. Builders whose current pump runs at full speed constantly gain quieter idle operation and automated ramp-up under load. Systems without PWM control cannot use the variable-speed function.

Perguntas sobre este artigo

Will the 12 V PWM signal from my older motherboard header control the pump speed reliably?

The pump uses a sine-wave precision drive circuit that accepts standard PWM input, so a 12 V header will regulate speed as intended.

How can I verify the pump is running correctly after installation?

With coolant filled, the permanent-magnet centrifugal rotor should spin smoothly and the PWM curve will reflect the set duty cycle in your monitoring software.

Which fittings are included and what must I buy for 16 mm hard tube?

The default package ships without plugs; you need male-to-female adapters for both inlet and outlet to fit OD 16 mm tubing without clearance issues.
