What customers say
Customers overwhelmingly praise the ULTITUBE D5 100 PRO for its exceptional build quality and thoughtful design, positioning it as a pinnacle of water cooling engineering. Reviewers value the borosilicate glass reservoir for its superior clarity and durability over acrylic, significantly enhancing the loop's aesthetic and longevity. The internal structure is lauded for promoting rapid de-bubbling and optimal flow dynamics with a D5 pump. Precision machined metal components convey substantial durability, justifying the premium investment. While the price is high, enthusiasts find the uncompromising quality, reliable performance, and seamless integration capabilities make this top-tier centerpiece a worthwhile, long-term purchase for serious custom builds.
Know before you buy
No, the ULTITUBE D5 100 PRO is a reservoir unit only. You will need to purchase a compatible D5 pump separately to complete the assembly.
It is designed to fit all standard D5 pumps manufactured by Aqua Computer, as well as most third-party D5 pumps that follow the industry-standard design.
The membrane allows for automatic pressure compensation within the loop. This prevents pressure buildup caused by temperature fluctuations, which protects your seals and components over time.
The integrated LED ring uses Aqua Computer’s proprietary RGBpx interface. To control the lighting, you will need an Aqua Computer controller or a compatible motherboard adapter.
Borosilicate glass is significantly more resistant to scratches and chemical staining than standard acrylic or PETG reservoirs. It maintains its clarity much longer, even when using colored coolants.
Yes, the included mounting hardware is versatile, allowing you to install the unit either on a side or rear chassis wall, or as a standalone vertical mount.
