How do you locate very, very small leaks?
I've got an EKWB hard tube system, custom built, that seems to have a very, very small leak someone in it. In my pump reservoir I've seen the fluid level drop by about 1mm every two months or so. It's such a small leak that I suspect it's evaporating before it ever drips. Or, is this just some kind of normal evaporation somehow?
The prior build never seemed to change its level. When I added my NVLink and the EKWB terminal bridge to cool my double RTX2080Ti's I also replaced the default reservoir from the D5 REVO 140 pump unit with a taller cylinder. So, I'm wondering if it might even be an O-ring on the acrylic cylinder that's not sealing perfectly at the top or bottom that might be causing leaks/evaporation.
Anyone have any similar experience and care to share how you solved it?
