Näytönohjaimen vesijäähdytin Alphacool RTX 5080 Phoenix läpinäkyvä hopea backplatella

Alphacool RTX 5080 Phoenix Transparent Silver is a full-cover GPU water block engineered to cool NVIDIA RTX 5080 graphics cards within custom liquid-cooling loops. The block features a transparent acrylic top that allows visual monitoring of coolant flow and a silver-coloured metal frame that integrates with the included backplate for additional structural support and heat spreading. Designed for direct cooling of the GPU, memory modules and voltage regulation components, it reduces operating temperatures and acoustic noise compared with air-cooling solutions.

Advantages

The transparent top provides clear visibility of coolant circulation and makes leak inspection easier during system assembly or maintenance. Precision-machined coolant channels and a thermally conductive cold plate ensure efficient heat transfer away from the GPU die and adjacent components. The included metal backplate reinforces the graphics card PCB and contributes to passive heat dissipation. This water block supports common G1/4" fittings and standard mounting layouts for RTX 5080 cards, enabling compatibility with most custom loop configurations.

Suitable for

• Custom liquid-cooled gaming PCs targeting lower GPU temperatures and quieter operation
• Workstation systems requiring sustained performance under heavy GPU loads
• Hardware enthusiasts building visually transparent cooling loops
• Systems where PCB reinforcement and improved heat spreading are desired

Key specifications

• Full-cover water block for NVIDIA RTX 5080 GPUs
• Transparent acrylic top for coolant visibility
• Silver-coloured metal frame and integrated backplate for structural support
• Direct cooling contact for GPU die, memory and VRM components
• G1/4" compatible fittings for inlet and outlet connections
• Precision-machined cold plate for efficient thermal transfer

How to use

Install the water block following the manufacturer’s mounting instructions: drain and power down the system, remove the original air cooler, clean thermal surfaces, apply appropriate thermal interface material to the GPU die and memory/VRM areas, position the block and secure it using the provided mounting hardware. Connect the inlet and outlet to your custom loop using G1/4" fittings and tubing, then refill, bleed and pressure-test the loop to check for leaks before normal operation. Verify pump flow and coolant circulation through the transparent top prior to first use.

Recommendations

Use coolant and corrosion inhibitors recommended for multi-metal loops when combining different metals in the cooling circuit. Periodically inspect seals and fittings for tightness and check coolant condition; perform scheduled maintenance and coolant replacement to maintain optimal thermal performance and prevent contamination.
