Well, like I posted before two of my pumps were making noise and one finally died today.

Were you closing the cap tightly?
Did you fill coolant to the top?

Well, like I posted before two of my pumps were making noise and one finally died today. I wonder how long it will take to get a replacement in the US? Let's take a pool. 1 month? 2 months? 3 months? 4 months? Never?

While BMW is sorting you out, may I ask what coolant that is? Its a lovely lime shade.

Impressed to see Bitmain helping with a pump.  Good to see not sending them over to syscooling.

It's the coolant you recommended off Ebay on the first page of this thread. They currently don't have anymore, but I had some extra.

I'll let you all know how it takes to receive a new one. The pumps are rated for 50,000 hours. That's 2 years running 24/7. Having ANY of them go bad in the first few months should not happen when they are rated for 50,000 hours.

Can't close the cap tightly because the the heat would create too much pressure in the loop. I keep it loose so there is a vent. And I don't fill all the way to the top, but fairly close.

Doesn't everyone keep the fill hole loose? You don't want too much pressure in the loop. Going from 28 to 40 is going to create a lot of hear and pressure.

[MyRig]

Please keep the cap closed!!!!!  if you are worried about the pressure, may be wait until 30's then close the cap nice and tight!!

Agreed on this. But realistically there isn't that much pressure build up as the difference in density between 25 and 40C is 0.5% by volume. You've got ductile tubing which isn't rigid and is more than comfortable absorbing that.

Well, yes, I do keep the cap closed and use a screw driver to close it. I just meant I don't make it real tight. It is a sealed system, so I know it has to be closed. It always did make me wonder where the pressure goes to when the coolant heats up? I guess the loop is rated for some pressure, right?

By the way, what would happen if you don't fully close the fill hole? I've always kept mine closed up, just not very tight. The fill hole screw gasket (O-ring) is definitely making a good seal.

Not sure they are all the same. My father has 3 C1's running in his basement and on one of his pumps he went to unscrew the fill cap to fill it up a little more and the fill cap went shooting across the room and the coolant started shooting out of the top of the fill hole. There was a huge amount of pressure in that loop and his top temperature was only 41. He had some serious pressure in his loop.  The only thing that could of done that to him was the heat. If there's no vent, it gets stuck in the loop and possibly takes advantage of the weakest areas where it can all leak out. No?

Agreed.  My pump started leaking a week ago, it was shooting out like a can of coke shook up.  Kept going on for some time spraying coolant every where due to the heat build up.  Bought another pump, just waiting to order another C1 to have 2 in the system, but the Bitcoin value keeps dropping.  Warning to others, keep watch where you have it running, mine ran for a couple weeks, then like many others the pump started leaking.  So glad I was home when it happened and it didn't short out everything.

Are you worried about losing too much coolant because of evaporation? The cap is closed. But excess pressure can escape.

I would like to know the reason for this also. WHY does the fill cap need to be closed and tight? I would rather have a loose fill cap and a running miner then one that is slowly building up pressure ready to pop. That's why cars have a vent in their cooling system. System gets just a little warmer then normal, the coolant will flow into the over flow tank and not put too much pressure on all your hoses/connections. If the fill cap is screwed on but not sealed it would take quite a long time for any evaporation to happen that would ever cause a problem. All you need to do is check up on them once in a while, that's all.

Anyone know the screw thread size for the radiator (to connect fans to it)?  I purchased some M3 .50 (the same size my other radiators from another brand) and some M4 .70 screws (the size of the one on the Antminers) today, but neither is correct, it seems to be somewhere in between.

I have another question. My father owns 3 C1's and one of his pumps is producing high amounts of foam/bubbles. Is there a trick to get rid of these foam/bubbles? It was actually running fine since he got them, but this foam/bubble thing just started. We are using this coolant.

I also want to thank BitmainWarranty for such a fast turn around on my broken pump. I reported it broken yesterday and today I received a replacement pump. I'll be installing it tomorrow.
Thank you.

It must be filled enough such that the return tube's flow diverter is submerged.

Water and soap do not make a good coolant.

The screw is custom-made and not standard,you can't purchase it from market yourself.
