Water flows back from my radiators to my reservoir.
Water flows back from my radiators to my reservoir.
I'm experiencing some difficulties that have made me reluctant to turn off my computer. The issue is shown in the attached image: my pump has an inlet on its right side, drawing water from the radiator, which then pushes water into the graphics card. When I power down the computer, water starts flowing back into the reservoir, causing air movement inside the radiator. At speed level 3, the water level is about an inch higher than it was before, and I hear "water drops" coming from the right radiator. Many games became unplayable (in Dark Souls 3 it took roughly 10 seconds for the game to close), and I often encountered an NVIDIA driver error. Now, with speed set to 3, the problems have disappeared. I suspect a heating issue might be the cause.
I've noticed some setups where the reservoir isn't positioned at the highest point, and it never caused problems. Keeping the pump and reservoir in place seems fine, but if the only viable option is to avoid a pump/res combination and use a higher reservoir, I could live with that. Any suggestions would be appreciated.
I recognized the issue - the front radiator is positioned in a manner that when flow stops, with I/O fittings on the top of the rad, it creates a semi-airlock. Filling it completely would remove air, or rotating it 180 degrees would place I/O ports at the bottom, avoiding an airlock.

Thank you for your message. I measured and found that there is enough space to leave the fittings as they are, both on top, allowing a 180-degree rotation of the radiator. Should I place them on the side (facing the pump) or keep them as is? Also, would it be suitable to install a drain port (in-line or T) between the pump inlet and the radiator?
The fitting position shouldn't affect the outcome, it's just a matter of preference. If you were installing a drain or T-line, that spot would be ideal because it's the lowest point in the loop.
