Watercooling Problem, Need Assistance
Watercooling Problem, Need Assistance
I’ve been working on fixing this problem for a few weeks, but it’s turning out to be quite a puzzling situation. Initially, I suspected the computer was overheating and needed a thermal flush and repasting. After applying new thermal paste to the CPU and reattaching the PETG tubing, I added distilled water to clean the system. The pump failed to activate, so I suspected either the pump or the thermal paste. I removed the pump from the reservoir to check for blockages, and everything appeared clear—clean and dry. I reconnected it, refilled with distilled water, turned the PC on, and it started pumping automatically...right?
Next, I added distilled water and ran the system for a few hours before draining it and installing PrimoChill Vue. The computer ran smoothly for about six to seven hours, then I powered it off, went to sleep, and woke up later—when I turned it back on, the pump wasn’t working. I figured it might be related to the SATA connection on the power supply. I replaced the cable and tried again, but nothing changed. As a last option, I drained the entire unit, removed the pump, cleaned it thoroughly, and reattached it. Now it’s functioning properly.
I’m unsure what to do next. This issue is making me feel stuck and unsure how to proceed. Any advice or similar experiences would be greatly appreciated.
Ps. The fluid before PrimoChill was Thermaltake High-Performance C1000.
The temperature readings look acceptable – does this merely confirm functionality when it operates?
Does the pump consistently start up with the system, or does it sometimes fail to power on? This should be the initial check before moving on to further troubleshooting.
If the pump runs every time the PC turns on, the problem likely lies elsewhere, not in power supply. It’s probably a restriction or air lock preventing proper flow. There appear to be more than necessary 90-degree fittings, but they may not be enough to block flow significantly. A sign of success is that the pump functions when disconnected and reconnected, especially if you allow it to vent or open.

There appear to be numerous 90-degree fittings, but they may not be necessary enough to significantly block flow. A useful test is disconnecting and reconnecting the pump from the loop; if it functions, check whether opening the reservoir cap vent or drain restores flow. Ensure coolant flows through the CPU block using the correct in and out ports. Often, the CPU block has a dedicated flow path, and reversing it can cause issues.
