FormulaMod D5 Pump-Reservoir Combo 18W PWM 90mm Reservoir Black

SKU CH-DS3M-CK2V3

A D5 pump-reservoir combo with an 18 W PWM pump and 90 mm reservoir for liquid-cooled PCs

  • TypePump
  • ColorBlack

Option 90mm

  • Efficient liquid cooling with 18 W PWM pump
  • 65 mm reservoir diameter holds ample coolant
  • Adjustable PWM speed matches system load
  • Aluminium-alloy shell dissipates pump heat
  • Integrated pump-reservoir unit simplifies loop build

FormulaMod D5 Pump-Reservoir Combo

This FormulaMod D5 pump-reservoir combo integrates an 18W PWM pump with a 90mm reservoir for custom liquid cooling loops. The black aluminium alloy shell aids heat dissipation while housing the pump in a single unit. It suits builders assembling a new open-loop system or refreshing an existing one.

Thermals noise and power draw

The 18W PWM pump adjusts speed to match thermal load, reducing noise when the system runs cool. Aluminium alloy construction transfers heat away from the pump body during continuous operation. A 65mm diameter reservoir holds enough coolant to stabilise temperatures under sustained workloads.

Upgrade path and fitment

This combo replaces separate pump and reservoir components, saving space and simplifying tubing runs. It is not for builders who need a second pump for redundant flow or a larger reservoir capacity than 90mm. The unit requires correct inlet and outlet orientation and must never run dry.

Highlights

  • Efficient liquid cooling with 18 W PWM pump
  • 65 mm reservoir diameter holds ample coolant
  • Adjustable PWM speed matches system load
  • Aluminium-alloy shell dissipates pump heat
  • Integrated pump-reservoir unit simplifies loop build

Questions about this item

How do I install the 18W PWM pump-reservoir combo and avoid the most common mistake?

Mount the unit so the pump inlet never points downward, fill the 65mm reservoir with coolant before powering on, and verify inlet and outlet orientation before tightening any fittings.

What maintenance will the 90mm reservoir and D5 pump need over time?

Periodically check coolant level in the 65mm diameter reservoir, top up when low, and clean the aluminum alloy pump shell if dust builds up on its cooling fins.

What limit appears first when the 18W PWM pump runs continuously under load?

Running the pump dry will damage it immediately, so the first limit is coolant loss — keep the reservoir filled and the inlet submerged at all times.
