It has corrosion inhibitors in the fluid itself. So you should be fine. Although it is my personal rule of thumb that the less different metals you can put in the loop, the better. And silver wouldn't do much because pastel also has Biocides in it too.

I wasn't planning on having silver in my loop, I just found out that Monsoon started plating the inside of their compression fittings.

Real Silver ????



Silver is 0.15
Nickel is 0.30

So you have about 3 times the galvanic potential that exists between copper and Nickel

Still.... in order for galvanic corrosion to take place, you need an electrolyte. The coolant may be perfectly electrolyte-less on day 1 but metals will leach in over time and therefore you can't depend on distilled water being electrolyte fee over time. I don't think anyone will say with certainty that corrosion won't occur .... but I think you could say that:

a) With the inhibitors in the pastel, you are a helluva lot better off than you would be with distilled water.
b) The rate of corrosion that would occur would be so slow that it would not be of any significance during the normal service life of the computer.

As Martin says ..... "But I don’t think you will completely stop corrosion. The idea is to keep it at bay long enough and/or reduce it for the intended service life.". From everything I have seen or read, the pastel from Mayhems does an excellent job keeping it at bay. read more here;

Honestly I don't know for sure, I've just read a couple people mentioning it. I'm prolly worrying for no reason.

Yeah I noticed that too, my solution was to switch to XT-1 when I put those new silver plated fittings in as I'm over cautious with my loop. biggrin.gif

I'll echo Zy here .....see pics in post 5966 ....did the vinegar / water .... bicarb thing ....flushed flushed flushed ... ran a week with distilled , measured pH w/ $2500 meter and got a 7.03 at end of week. Drained and installed pastel....will be taking down and re-doing before summer.

Thanks Zy and Jack
I will be using the solutions you recommended to clean the loop up.
First the lemon water then the vinegar water and final bicarb rinse.

Lemon water or vinegar water, not both. It would be redundant, they are a cleaning/descaling solution. Their purpose is mainly to get any flux or crap out of your loop, then the bicarb neutralizes everything so it doesn't mess up the pastel. I'd go with lemon water personally, vinegar is just 8% acetic acid, 90% water, and 2% fermentation biproducts. Acetic acid is REALLY potent stuff, it could melt your face off, literally.

got some fluids in but for some reason the uv effect in my system doesnt last more than a day. i get all of my mayhem products from frozencpu. i found someone having a similar issue due to the brand that makes the uv light. i am using the phobya uv led strips they are pretty bright but they do give off a bright purple light. heres the list of components in my loop if it helps. EK Supremacy CPU Block, XSPC Pump/Reservoir, EK GPU Block, Black Ice 360mm and 240mm Radiators, PrimoChill Acrylic Tubing, PrimoChill Fittings, Mayhem X1 Coolants and dyes. heres pics for now with the side panel off the purple doesnt seem as powerful/strong when the side panel is on of course. im also considering going to just white light with plain mayhem dye and give up on the uv dye.
