Usually when you chanel water in tight little holes.. thats called filtering.

So the result is kinda obvious.


In your case, left over flux from radiator, or something that was stuck in the radiator is probably the culpret. PHN = pH Neutral... that means the algaecide is pH Neutral... so i highly doubt the PHN had any role in your blocks blacking up.

We only use silver because its reusable.. thats the main point... and the backup is that the coolant gets stronger antimicrob wise over time.



Well the entire thread is basically a rant. But its an i told ya so rant. This problem isnt new and there is NO way to fix it. Im sorry, but you guys really need to learn what a dye is.

The fate of all dies, is simple... it will either bond to your tubing and stain the crap out of it, and then the dye will fade... or it will get sand blasted onto the copper like how a paint gun works when you have accelerators.

Asking fesser or any company to fix this would mean they would need to design an entirely new water soluable, non bonding, dye that wouldnt bond to metal or platics.

Then thats not a dye.

I dont care what manufactor says be it Fesser, coolit, or even koolance. A DYE is a DYE PERIOD.

Its that simple.

I've used the rad in question on previous builds (without any issues) and I'm always very meticulous when cleaning out my loop. Rad always get flushed numerous times with boiling water and left overnight with cola.

It may be a rant, but it's a rant that obviously many users are interested in, surely that's the whole purpose of this forum, to communicate, share and help. All three of with you'll find in this thread.

I for one have found this topic interesting, but then I do love a good mystery!

If we find gunk in our loops should we just.....keep it to ourselves
