Why not to use dye's

post #1 of 8
Thread Starter 
A quick background...
-2 loops
-one had blue dye the other red dye
-fluid was primochill
-these loops had been running for ~9 months

The GPU (RED) loop faired well, not much grit or discoloration in the liquid while the CPU (BLUE) loop was completely clear when drained.

I have before and after pictures of the CPU loop that had the Blue Dye
BEFORE:


AFTER (after a boiling vinegar bath x1, did it twice but only took one pic)


The results are damning... never never again will I use dye. I have spent the last day, and will spend most of today cleaning up all the blocks. Thanks to [AK]Zip's tips on how to clean everything.

So far, I have disassembled and cleaned the GPU, CPU, and NB blocks. Next up is cleaning the radiators w/ some hot water/vinegar mix. Also ordered some new tubing (wanted to switch to white for a while now anyways!), a silver coil to use with distilled water, and some mx-4 thermal paste (figure this was a good time to change my TIM everywhere).

I know you said Dyes have you ever tried pre mix i agree with dyes as it an additive so has to work with a broad spectrum of base liquids but you may not get the same with some premix also most i have seen say only use for about 6 months.
my current case seems to have had more of an issue with the blue stuff in the Radiator which seemed to survive a 2 hour white vinigar bath than with the coolant

Why you shouldn't use pre-mixes either.

Your primochill has failed not the dyes alone.

1) What tubing did you use
2) Have you actually checked what the gunk is
3) What was the PH of the liquid
4) was the liquid glycol based
5) was there any other additives in the system

So many question's to be asked but over all that is not dye gunking.

and if it was dye how did you remove it just with vinegar because if it was so called dye then why is you block not stained.

Primochill tubing, and Primochill Liquid w/ their Dye bombs.

FYI, the blue dye specifically was the problem. The red dye did not cause havok inside my gpu blocks (just minor stuff).

ah oky i cannot comment on there dye bombs. As know its more than just dye.
how ever you'll find that the glycol maybe the cause this not the dye it self.

im not doubting what you are saying just pointing out its normally the glycol or plastic tubing that is the main issue.

Although I clean gunk out I generally leave the oxidation untouched in the (possibly mistaken) belief that it'll oxidise again anyway if exposed to oxygen and that it protects the copper from further oxidation.

If you mix lemon juice with salt and leave copper in the solution for too long it produces an interesting but probably unwanted etched effect. Guess who forgot to remove some copper from a lemon bath.
