Custom liquid cooling system failed – manufacturer not providing any assistance. Assistance needed!
Hey there - I received a costly setup from Radium PCs in Melbourne, AUS (Adelaide is my location). Sadly, it seems the system leaked and the GPU began overheating, causing shutdowns. They didn’t provide any support—no contact info, no help offered. Fixing it is urgent, but I’m eager to restore functionality. Please share updates and photos; I’m worried about wasting money on Radium.
Good news: leaks appear to be coming from the piping that connected to the chassis, not the motherboard. It looks like the GPU overheated because there wasn’t enough coolant left in the system to keep it running properly. The temperature sensor showed 115°C, but I’m hoping this indicates the GPU is still operational and not permanently damaged.
I’ve tried running the PC and seeing high temps, but I don’t want to risk further damage or legal trouble—my investment exceeds my car’s value. I’m new to liquid cooling and haven’t built a system in years, so I need guidance on testing and fixing this. Any advice would be greatly appreciated.
Thanks in advance for your help!
It seems like a serious issue is present. The GPU appears to be okay thanks to its thermal safeguards. You’ll need to remove the fitting around the leaky section and assess the damage. Possible causes include an original failure, a crack, an improperly finished tube, or incorrect length—many factors could be involved. For the fluid, a complete drain and flush are necessary. A positive outcome is replacing the thick, cloudy liquid with a clear one. The simplest solution is to run soft tubing to two buckets: one connected to the leak and the other empty. Let the system work by gravity to prevent dry spots. Just remember, don’t attempt any of these steps until you confirm there’s no radiation on the line, as this could cancel your warranty.
Examining the pipes shows they're quite full of liquid, with a few bubbles in one area seeming okay. In a complete loop, both the CPU and GPU tend to overheat if there isn't enough fluid flowing. To easily identify any leaks, use paper towels and follow @jaslion's advice. If the builder doesn’t honor the warranty, you won’t lose anything unless you intend to take legal action.
I think theres severe clogging going on as that liquid is already showing signs of separation theres BIG clumps of the opaque suspension dust going on which is really bad.
You’ll need basic plumbing tools and possibly a compatible fitting for the inlet and outlet ports. Consider getting a drain strainer, a flow control device, and a refill valve to manage liquid levels. The fitting should help prevent excess liquid from escaping during use.
You selected a fitting designed for soft tubing and sourced the appropriate soft PVC tubing from a hardware store—generic options are fine. Make sure to match the inner and outer diameters with your connection. For the fitting, identify the reservoir or fill/drain port to choose compatible components. After installation, start flushing with tap water, then use distilled water for the final flush and clear the liquid completely. You can add dye, but avoid opaque finishes—it will make the mess worse.
You might be covered under the warranty. Simply request a complete refund or purchase a system from another vendor.
