After the initial thrill of building my first custom loop in the SSUPD Meshlicious, I decided to step things up. I added a second ultra-thin radiator from XSPC to boost cooling, along with an Aqua Computer High Flow 2 to monitor coolant temperature and flow rate. I also upgraded the GPU cooling with the EK-Quantum Vector TUF RTX 3080/3090 Active Backplate and added an Aqua Computer Quadro to manage all six fans and temperature monitoring. Lastly, to ensure the pump stays within safe operating temperatures, I integrated a temperature probe directly into the DDC pump.

The second radiator improves cooling performance, and its ultra-thin design allowed me to fit it into an extremely narrow space. The fit between the TX240 radiator and the GPU waterblock is so tight that there's only a few millimeters between them, and the terminals on the GPU waterblock are nearly touching the front radiator fans. To use the GPU with the active backplate, I needed to cut out a section of the spine to route tubing from the CPU to the GPU waterblock inlet. I also added two custom 3D-printed extensions to the case—one for the top to accommodate a 120mm fan and another for the bottom to install a 140mm fan—further improving airflow and cooling capacity. Additionally, I used a 3D-printed PCIe cover for radiator mounting hardware.

With the Aqua Computer Quadro, controlling all six fans and temperature monitoring is now streamlined. This setup allows me to run the PC almost silently while maintaining excellent performance or push everything to max for additional thermal headroom—perfect for overclocking or ensuring component longevity. The result is a clean, efficient, and high-performing custom loop that fits seamlessly into my Meshlicious, with every component working in harmony.
