Message 2017780 - Posted: 4 Nov 2019, 10:43:24 UTC

Since my computer, with the 3 gpu cards gtx2080 Ti, is having had two water leaks and maybe on its third water loss now, I wonder if other people had similar issues. This computer is less than 5 months old.
Thank you,

Miklos

What components are you using? Are you making sure the connections are tight (but not too tight)?

One of my systems has been watercooled for well over a year with a couple different configurations and I’ve never had a leak.

My main machine is watercooled, been running for 18 months almost constant and have not had to touch it apart from the regular dust bunny extraction.

Its running on de-ionised water with a silver coil and the water and the blocks look as clean as when first assembled.

I've been water cooling my systems for a few years now. Not had to do much other than the dust bunny hunt with them. No leaks, ever.

I have never had a water leak on any of my water cooled components. Some of the hybrid gpus are over 3 years old. Sounds like your system builder didn't know what they were doing and incorrectly assembled the components.

It was built by Maingear, but this is all I know about the system:
GenuineIntel
Intel(R) Core(TM) i9-9980XE CPU @ 3.00GHz [Family 6 Model 85 Stepping 4]
(18 processors) [3] NVIDIA GeForce RTX 2080 Ti (4095MB) driver: 43040

Yes, I know you had a system builder build it for you. It seems Maingear does not know how to assemble custom loop cooling systems correctly or used cheap components. I assume everyone that has responded so far in this thread either has assembled their custom loop themselves and taken the time to do it correctly and with quality parts to insure that they have no leakage issues. The AIO cooled cpus and gpus are built by established vendors with years of experience. The only problems I have ever have with the AIO systems is the parts quality is cheap and fans die or pumps die. I have never had a leak from them.

oddly i post this on oc thread on reddit.
they run ln2 pots and water cooling .
put as much detail as you can with your hardware on their.
they should be able to help you.

I'm running watercooling for at least ~ 15 years now. I cannot really remember when i started ( i did cnc my own blocks waaay in the past when watercooling was just starting ) but my 3 x 8800 gtx were full cover watercooled. I NEVER had a leak. I did have cracked plexiglass covers due to heat changes, so i quickly found the disadvantage of the " looks".
It really depends on the gear you are using.

- I NEVER use all in one setups. To much risk and they are cheaply build compared to my own custom build. ( not more money is better but i use better couplings and tubing for example. )
- I NEVER use push in tube fittings. Only screw on fittings. Push tube on pillar and clamp by screw cap. Never leaks.
- I use Tychon tubing because it can handle different fluids and has a rubber like feeling, easy to handle less stress on the blocks / pcb's. NO hard plastics for me.
- The 2 Laing ddc1 12V pumps i have running right now are ~ 15 years or older, i got them when they were released anyway and they are still my first pumps running right now as i type.
- As liquid i have always used car engine coolant, pure form. First the blue one and now the red / pink one. I do change the fluid once in 5 years. Because it does not erode metals or rubber O-sealings and most important it does have additional lubricants in it to lube your pump bearing. In my case 2 x Laing ddc1 ceramic bearing.
- My setup is pretty upgradable, i use 2 x 4 x 120 mm radiators with 4 x 120 mm fans on it. They have cooled all my hardweare i have used, from 8800 gtx till now 1 x 1080 TI. with 2 x Xeon cpu's E5. I only swap GPU's and CPU's with for both new screw on fittings, or in case of the CPU if the block can fit a new socket with an adapter i use that instead.

From my experience, don't use too much plexi glass stuff it can crack and risk of leak, my 1080 Ti has a EK full cover block from copper with POM cover and i would prefer a metal or rvs cover in the end but this one does well.
The dual Xeon's have both a Phobia UC-2LT block, not really expensive either.

This system i game with, running Seti with under Ubuntu. Not 24/7 but i CAN run 24/7 if i want to. ( elektricity bills :( )


Good luck :)

I agree with Marco's sentiment to avoid the plexi or lexan "bling" covers made for RGB lighting. They don't take thermal changes well and and are easy to crack from just finger overtightening. Some plastics are soluble with certain cooling fluids also. I always go for either metal covers or acetal plastic for the parts that have fittings. I have so far done just soft tubing with compression fittings. No leaks. The only leaks I have had was a bad batch of 90° fittings that weeped at the O-ring when turned. Got a better quality fitting and no problem since.

Thank you for taking the time to answer my question on water cooling. I am going to ask Maingear about their cooling system again, since I should not have to be adding water after two teck visits of re doing the cooling system and all in less than a few months of usage.

I too would be asking Maingear to fix the problem correctly. You paid a lot of money for the system and it has not performed correctly. You should have Maingear make good on the product warranty.

You say you have to refill the reservoir?

Did you find leaks or moist spots?

If there are no wet spots or signs of leaks it can be ( i had that myself ) that the radiator or tubing or blocks are not fully de-aired. That some air bubbles are in there. In time the micro bubbles leave the radiator and collect to the highest point. If the reservoir is the highest point in the loop. Resulting in " lesser" fluid in the reservoir. This does no harm. Just refill till its not happening anymore.

I can expect some air bubble outgassing within the first few days, I see that on my rigs. But I normally purge the majority of the air from the system during the fill maintenance by moving the rig around on the table to move the air to the reservoir while still topping up the system.

Nick has had that system running for months now and the micro bubbles would all have collected in the high point in the loop by now and the reservoir level should have equilibrated long ago.
