Bomba y depósito Alphacool 15381 acrílico aluminio plástico negro transparente

The Alphacool 15381 Acrylic Aluminium Plastic Black Transparent pump & reservoir combines a compact centrifugal pump with an integrated transparent reservoir designed for custom PC liquid-cooling loops. Constructed from acrylic, aluminium and plastic, the unit provides a clear viewing chamber for coolant level monitoring while maintaining a black accent finish. With a tube diameter of 7.65 cm, an overall length of 25.1 cm and a unit weight of 621 g, this component is intended for installation inside desktop computer cases where controlled coolant circulation and visual monitoring are required. The pump accepts 8–13 V operating voltage and supports 5 V RGB lighting control for systems that incorporate addressable illumination.

Advantages

The integrated pump and reservoir reduce the number of separate fittings and simplify loop plumbing, while the transparent acrylic reservoir allows quick visual inspection of coolant condition and level. Aluminium and plastic construction balances rigidity and weight, and the supported 8–13 V pump voltage range enables compatibility with common motherboard and fan controller outputs. Built-in 5 V RGB compatibility offers consistent lighting control when connected to an addressable RGB header.

Suitable for

• Custom water-cooling loops in desktop PC builds
• Systems requiring compact combined pump and reservoir units
• Builds where coolant monitoring and visible flow are desired
• Enthusiast rigs with 5 V addressable RGB support

Key specifications

• Materials: acrylic, aluminium, plastic
• Tube diameter: 7.65 cm
• Length: 25.1 cm
• Weight: 621 g
• Pump operating voltage: 8–13 V
• RGB voltage: 5 V (addressable RGB)
• Colour: transparent reservoir with black accents

How to use

Mount the pump & reservoir securely in a compatible location inside the case using appropriate brackets or mounting points, ensuring the unit is level to avoid air pockets. Connect the pump power to a compatible 8–13 V supply such as a motherboard fan header or dedicated controller, following the host hardware specifications. Fill the reservoir with recommended coolant compatible with acrylic and aluminium components, bleed the loop to remove trapped air, and verify correct flow before prolonged operation. If using the RGB feature, connect the 5 V addressable header according to your motherboard or RGB controller documentation and configure lighting via the corresponding software.

Recommendations

Use coolants formulated for mixed-metal loops and avoid highly acidic or abrasive additives. Regularly check coolant level and clarity through the transparent reservoir, perform periodic maintenance including coolant replacement and loop inspection, and ensure fittings and hoses are rated for your selected tube diameter. Adhere to the pump operating voltage range and RGB header specifications to ensure reliable operation.
