Details
The Aquacomputer ULTITUBE D5 200 Reservoir with D5 PWM Pump is a tube reservoir with an Aqua Computer D5 PWM pump already mounted in its base, so it needs no separate pump top. It holds approx. 470 ml of coolant in a borosilicate glass tube 200 mm long and connects to the loop through two G1/4 threads.

Borosilicate glass instead of acrylic
Every reservoir in the ULTITUBE series is equipped with a tube of borosilicate glass. In contrast to the acrylic glass (Plexiglas) often used for tube expansion tanks, borosilicate has a very high hardness and scratch resistance. It also has a very low thermal expansion and excellent chemical and thermal resistance. The tube is 65 mm in outer diameter, with a wall thickness of 5 mm. The number 50/100/150/200 in the product name refers to the tube length in millimeters.
Metal rings of black anodized aluminum are firmly bonded to both ends of the glass, and being outside the coolant path, they never come into contact with the cooling medium. Base and lid are made of resistant, resilient acetal and screwed to the tube. After unscrewing the lid, a large opening is available for filling.
Filter and seals
A filter element of fine stainless steel wire mesh is integrated in the bottom of the container. In addition to functioning as a particle filter, it separates air bubbles from the coolant. The mesh sits in a molded rubber part and can, for example, be rinsed out under running tap water. The seal in the upper area of the glass tube is a molded rubber part too, designed for easy assembly. It is therefore securely positioned when the lid is screwed on.
D5 PWM pump
The pump is installed directly into the base of the reservoir and held there by a fastening ring with a seal. Its performance can be set using a PWM signal, and a speed (speedometer) signal is available to monitor the pump function. The pump's electronically commutated spherical ball motor runs extremely quietly and has a long service life. Aquacomputer says care was taken to ensure optimum flow behavior while developing the reservoir. The result, it says, is extremely quiet and smooth pump operation with noise and vibration at a bare minimum.
Mounting
Fastening material in the scope of delivery covers mounting on a side / rear wall of the PC case or a standing mounting on its bottom, which Aquacomputer prefers for stability. Four soft rubber decouplers (buffers) are included for decoupling. Brackets for a standard 120 mm fan mounting position (34112) or a 140 mm one (34113) are available as accessories. For an additional, vibration dampening fixation in the upper area of the glass tube there is the rubber fixation ring (34114). These three are not included.
What the loop needs
The tank is supplied without connections, so order two suitable G1/4 fittings separately from our fittings section. The return line goes to the port engraved IN. Power comes via a 4-pin Molex drive connector from the power supply, while PWM input and tacho signal run separately on a 4-pin fan connector, connected to a compatible PWM fan header. Fill with Double Protect Ultra coolant or water.

Notes
- Please note: fittings are not included in delivery.
- Use only Double Protect Ultra coolant or water, never a coolant with solid micro particles. Those particles, found in various opaque coolants, damage the D5 pump bearing and may lead to destruction of the borosilicate glass tube.
- The pump must not run dry: fill the loop with coolant before powering it up.
- Screw fittings in with light force only, so the threads in the plastic base part are not damaged.
- To open the lid, hold the glass tube and turn the lid counter-clockwise without losing the gasket; do not use tools when closing it.
- A valid speed signal cannot guarantee an actual flow of coolant.
- During operation the pump rotor must not face down.
