Heat causes the liquid to expand causing the pressure. These pumps can't handle the pressure, that's why I believe mine failed.

Not in this case, he said he preheated the coolant before closing it.

Ok, please watch this youtube video I made of my pump spewing out the coolant only after one night. This was with the fill hole closed of course. If the fill hole was open, there would be no way for the pressure to build up.

I'm not sure this place allows videos to be embedded into the post, I doubt it, but here it is. It is 720P, so it is hi-def if you want to change it while watching. Can anyone explain how all that pressure gets in the system? And the green under the miner itself is from a leak somewhere, which I think is from the aluminum block and that in itself is sucking in air when the fill hole is closed. I have to get this fixed.

Bitmainwarranty, I'm going to need somekind of RMA for this. This shouldn't happen.

EDIT: The green coolant leak that's right in front of the miner ( as you can see it is green ) only happens when the fill cap it fully closed. If the fill cap is open, nothing leaks out and the paper towel stays white.

So because you're coolant level returns after you open it, its NOT expansion, and as far as we know its NOT a leak. What you have going on there is the algae or whatever it is producing gas. That's why you're getting bubbles accumulating and that's why you're getting the pressure build up.

Edit: I agree with your assertation that the 'leak' on the miner is a by product of the excess pressure rather than a leak leak per se.

So you are going to chalk this up to algae, when I have 5 other C1's with running with no problems at all. Then especially hearing from another person having the same problem right after my post indicates there may be some issue. And the coolant that's in there now is only 2 days old. I completely dumped all the old coolant when I switched my hose/pump. And that was only 2 days old. There is a problem with this miner. Algae is just a quick excuse to blame it on something we don't know about yet.
