Details
The Aquacomputer D5 Pump Core | PWM Equipped (41105) is a D5 pump motor without a top, with a PWM input and a speed signal on one 4 pin fan connector. It has to be completed with a suitable housing, a D5 pump top or reservoir, before it runs.
Properties
- Pump
- D5, electronically commutated spherical motor
- Speed control
- PWM signal or supply voltage
- Supply
- 8 - 24 V DC, 23 W at 12 V, 4 pin Molex plug
- Maximum head
- 3.7 m at 12 V
- Size
- 66 x 57 mm (diameter x height, without cables)
Motor and PWM control
Aquacomputer describes this D5 motor as a powerful pump engine, and says its electronically commutated spherical motor features extremely smooth operation and a long life. A PWM signal sets the pump speed. Alternatively, the speed can be controlled by the supply voltage. For monitoring, the pump additionally generates a speed signal, which shares the 4 pin fan connector with the PWM input.
Important: the Aqua Computer D5 pump has an optimized PWM input, so any Intel PWM standard compatible fan controller can drive it. On the PWM fan outputs of an aquaero 5/6 it runs without any heat dissipation at the aquaero, for example on the aquaero 6 LT. Aquacomputer adds that all other D5 pumps with PWM input currently available (as of January 2015) use different hardware. That hardware will not work correctly with the PWM outputs of aquaero 5/6 devices. In Aquacomputer's words, this pump is compatible with nearly any PWM fan controller on the market.
Protection and monitoring
An overheat protection first reduces the pump speed when the temperature reaches a critical level. If it keeps rising, the pump shuts down completely, then resumes operation automatically once it has cooled down. A valid speed signal cannot guarantee an actual flow of coolant.
What the loop needs
The housing is not included in delivery. It can be a D5 top such as the ULTITOP pump top for D5 pumps (41123) or the aqualis D5 pump top (41094), and more are in our D5 pump tops. Power comes from the 4 pin Molex plug on the PC's PSU, and the fan connector goes to a PWM fan header or controller.
Use Double Protect Ultra coolant or water. Coolants with solid micro particles must not be used: those in various non-transparent or opaque coolants damage the D5 pump bearing. The rotor must face up or to the side during operation, never down.

Notes
- The pump electronics are not water proof and must not get in contact with coolant; no submerged operation.
- Fill the system with coolant before starting the pump. To deaerate, sway the system gently or power the pump down and up several times until the rattling noises stop.
- The pump must not run dry for longer periods of time.
In the box
- 1x Aquacomputer D5 pump motor with PWM input and speed signal
