Ok, I've had this water cooling rig for two years. This weekend, I took it apart, cleaned and reworked it.
The problem:
It won't circulate on its own. Once I get it going, water flows. If I turn it off and back on, no flow. I have to use valves and blow air backwards into the system. Then it surges back. I open my valves and it continues to flow. It's the damnedest thing.
Changes:
The tube that went from the pump to the CPU had a split up the middle inside the resivior. I replaced it. The pump has a stock fitting epoxied and a hose of the same size clamped to it.
The propeller on the pump had wiggle room. It was made with slack in it. I epoxied it as I had read somewhere that it may help quiet the pump. I don't think that it did.
Kinks were replaced with 90 degree elbos. Not ideal but better than kinks right?
Everything else is the same as it had been for the last two years.
Thoughts:
Perhaps the pump needs the slack in the propeller?
Maybe the new hose that is clampped to the pump is somehow creating too much backpreasure? Perhaps the split in the old tube allowed it to work?
The system:
The system is a submersible pump in a gallon container. It has a rated 'head' of some 5 feet.
It goes from pump > CPU > GPU > Radiator > resivior.
The system is clamped from start to finish. The return line in the resivior dips far into the water to reduce the 'waterfall' sound.
The system is self contained INSIDE a full tower case. The pump sits at the very bottom. The radiator is at the very top, about 2.5 feet up. The CPU block is about the same hieght as the outlet of the resivior. The GPU is below that and then the water goes all the way up to the radiator. It worked before.
