Coldplate Alphacool 13890 Acrylic Transparent 145mm Width 420mm Depth 42mm Height

The Alphacool 13890 Coldplate is a transparent acrylic coldplate with dimensions of 145mm width, 420mm depth and 42mm height, designed for custom water-cooling applications in computer systems. It integrates aRGB lighting that operates at 5V RGB voltage and provides a visible coolant channel layout through its clear acrylic construction. The product aims to support efficient heat transfer in liquid-cooled builds while offering a modular mounting approach for straightforward installation.

Advantages

The transparent acrylic construction allows visual inspection of coolant flow and contributes to coordinated system aesthetics without obscuring internal routing. The integrated 5V aRGB lighting gives controllable illumination compatible with standard digital RGB headers and optional external controllers. The coldplate is dimensioned to fit a variety of custom loop layouts and supports simplified installation through the supplied push-mount kit that reduces mechanical stress during assembly.

Suitable for

• Custom PC water-cooling loops requiring a visible distribution/coldplate element
• Builds where 145 × 420 × 42 mm component dimensions fit available mounting space
• Systems using 5V digital RGB (aRGB) headers or compatible external aRGB controllers
• Users who prefer modular push-mount installation for easier maintenance and removal

Key specifications

• Material: transparent acrylic body
• Dimensions: 145 mm (width) × 420 mm (depth) × 42 mm (height)
• Lighting: integrated aRGB, operated at 5V RGB voltage
• Connection type: recessed, multi-part fluid fittings designed to reduce stress on the acrylic body
• Mounting: includes push-mount mounting kit for panel or radiator attachment

How to use

Install the coldplate into your custom loop by positioning it in the intended mounting location that accommodates its 145 × 420 × 42 mm dimensions. Attach the included push-mount pins to the radiator or case panel per the enclosed instructions, then push the coldplate onto the pins until it is securely seated. Connect fluid tubing to the recessed fittings, ensuring O-rings and fitting parts are properly aligned to maintain a leak-free seal. Connect the 5V aRGB cable to a compatible motherboard digital RGB header or to a supported external controller to enable lighting control. Follow standard coolant-filling and leak-testing procedures before powering the system.

Usage recommendations

Use compatible soft or hard tubing sized for the fittings, confirm clearance for the 42 mm height in your case, and perform a thorough leak test after installation. Control the integrated aRGB lighting via a 5V digital RGB header or an approved controller to prevent electrical incompatibility. Avoid overtightening any fittings to reduce stress on the acrylic material, and consult the enclosed instructions for the recommended sequence of mounting and sealing.
