Modded AIO watercooler performance degraded.

Mine corroded where the o-ring seals against the cold plate. Causing it to slowly leak. It looks like that o-ring might be molded to the cold plate. Anyway, if it isn't, you might want to take a look under there. Or not, if you want to take the "if it ain't broke" approach. If it is corroded under there it would probably be leaking already. And it doesn't look like it is. If it were you could replace the o-ring with some dope/sealant applied to it. You'd need to use something compatible with rubber gaskets. No RTV/Silicone(well...you might be able to get away with it here...but generally it's not a good idea...because it can cause the rubber to slip/squish out when installed). I use this stuff for such purposes...

It's basically heavy duty rubber cement infused with fine copper particles. It can be used on any type of gasket/seal, with any kind of fluid(coolant, fuel, oil, air, etc.). And is good for high temp applications too. I've used it on head gaskets, o-rings, and various paper gaskets. Good stuff. Never had it fail on me. ;)

Apart from the grey stuff that's also blocking the flow, the o-ring looks and feels fine, but thanks for that tip!
