Help solve water leak

post #1 of 22
Thread Starter 
I am having trouble finding my coolant leak in my build. When priming the system, I noticed it was taking a LOT of coolant. It had to be filled with more than 1 liter. However, I do have 2 360 rads and several fairly long runs of tubing in a large Mountain Mods case. It wasn't until I had cycled the pump a few times that I saw the water was severely leaking, collecting at the bottom of the case.

My fittings checked out OK from what I could tell and were not damp under or around them except one on my left 360 rad. This still wasn't enough to cause the amount of leaking that collected at the bottom as it was soaking. I looked that my in and out ports on the pump top and they were fine, my T line and shutoff valve checked fine and nothing was dripping from there. The best I can tell is it was coming from the first 360 rad from the bottom? When I installed the rads I didn't see any cracks or problems at the time, but the coolant coming out has to be from this area otherwise I would see a large leak like this at the top where the fittings are on the rad running down the outside. There is no water I can tell on any of my fans and for that much water it would be obvious. That is why I am assuming, although I can't tell where, it's at the bottom.

There is still coolant left in most (not all) the tubes and pump resv, with no leaks without it running. But when I power up for a while and the coolant starts to flow through the tubes and I put more in the resv, that's when I start seeing the leaking under the 360 rad.

I am using Black Ice SR-1 rads and Bitspower compression fittings. Not sure if anyone has seen bad Black Ice rads or not? Like I said, nothing I can tell, but this major leak has to be coming from here or else the other fittings and tubes would show the leaking there.

I am running out of coolant quickly and will have to get more or drain the system and test with DI water and drain then fill with the coolant. Any advice there for leaving the coolant for now or draining?

Thanks for any thoughts on checking this out and how I can test more.

You might of dammaged the rad did you use the correct screws that it came with ?

Your best bet would probably be to pull the loop out of the case, and assemble it freely. Then fill it up and check for leaks.

Don't worry about coolant, just go to your local grocer and pick up some distilled water for cheap.

Yes, I used the correct screws, but there wasn't enough for my fans and to mount the rad so I had to get more. They are the same size. I did see some there were about 5mm longer for using fan mounting with grill filters and was told that it would be fine as well. If they were a bit longer and still going into the same screw thread, that shouldn't matter because there is nothing to puncture.

I did by accident put some screws through on the front that while the same size did not line up with the fan mount holes in the rad. When I looked I didn't think anything was damaged, I thought just a bend or such in the rad grills inside didn't really matter, not that mine are, just something I thought was not too big a deal. Doesn't the water just run in the channels inside the rad where the fittings are? If so, nothing there looks damaged and nothing in that area ever had any screws in it beside the main ones.

It could be damage from somewhere, but I don't know how. I know some people had gotten defective rads or even ones with "micro fishers" in them that caused this sort of leak, that's why before I replace it I want to make sure.

Since my loop is complete, I can eliminate the fittings one by one and each tube run, therefore taking it out of the case wouldn't help and I still wouldn't have all it because of the two CPU blocks and video card block connections. It would allow me to see the rad better, but even then not much different beside what I see now as there is nothing glaring.

Take that rad out and fill it with water very likely you messed it up tubes do run where the screws go in at and if you go in to far you put holes in them.

This. Over tightening the rad screws can cause them to puncture the fin's of the rad and cause leaks.

I did not know that, when I put the screws in I made sure to get the right size and they even said replacement screws for Hardware Labs SR-1 on the FrozenCPU web site so I thought I was safe. They did go in pretty tight requiring a bit of push force when mounting the screws through the front of the case where the holes were. Even double checked to make sure I was lined up with the screw holes top and bottom before I did. However, I noted only those 4 holes, the left and right at top and bottom lined up, the middle did not so I left them out and just went with those to hold it firm.

The only screws on the inside were the replacement screws same 30mm size except for one where the UN mount is that was 35mm. I have fans as everyone does mounted to their rad, 25mm, but needed to add a UN mount bracket to one of them. That made it a bit too thick to attach the fan to the case so I had to use a 35mm on that one. There is no way I can tell to mount this otherwise since the 30mm are not long enough. Has anyone else done this with their mounts on the rads? I saw a youtube video where it was done and thought it would be OK.

I will test the rad outside the case and take some pictures later and post them. Hopefully I will find the problem. Is there any way to fix the leak if I see something I did besides getting a new rad? Hate to be out the cost, but if I messed up then I will do what I need to make it right so I don't worry.

Thanks for the tips and help.

Puncture the tubes. Fins do not have coolant. I bring this up to make sure that you do not jump to any wrong conclusions if you see a hole in a fin. If there is no coolant actually leaking, it may not be a problem.

Can you clarify what you mean by the difference in puncturing the "tubes" or "fins". If I understand, a hole or damage to the honeycomb type fins is NOT a problem if you see some, only the places where the screw holes are that mount the fans/radiator?

I did put a screw partly through some fins, but nothing I can tell where the screw holes are. When I removed the radiator from the case, I did find some coolant collected at the bottom and also some at the top where the top screw holes are on the outside (the side without the fittings holes). If I fill the radiator with water without the pump connected to it, is that sufficient enough to test for leaks?

fins are connected to the tubes so if you put it thru the fins you likely put a hole in the tubes. empty out the rad take it to the bathroom and fill it with water then move it around differt angles and watch for any leaks.
