Dyed watercooling fading.

[Emjay86]

Hey guys ive recently bought and set up a Corsair 800D chassis and watercooled the CPU (im yet to watercool the graphics cards) and ive noticed the colour of the fluid has faded. I have 4 UV lights inside the chassis that are intended to illuminate the UV reactive fluid within the tubes. It worked like a charm for around 4-6 hours and once I started the machine up again the fluid has gone to a very pale glow which is barely noticeable.

Basically im wondering what may have caused this (my thoughts are clogging up somewhere) and also what kind of things can I do to stop this from happening in the future and also to possibly fix it now.

Thanks in advance.

normaly dye fades if you use to much biocide is used or the PH of your liquid is out. We have found under test that if you add to much biocide (e.g our is 1 to 2 drops per 1 Ltr) this causes the dye to fade of if you liquids are -6.8 or +8.1 PH these will cause your dyes to fade.

A good test is to place some dye in a glass of di water and cover it and put it to the side for a few days. if it fades there is a problem with the dye if it does not then its your liquids. Do not do this with tap water as the chlorine in the tap water can effect the dyes.

The other explanation is that your cpu block (and probably radiator) have effectively sieved the dye out of suspension, and are now full of dye-coloured gunk. The solution for the cpu block is to take it apart and clean it, for the radiator, all you can do is hope it doesn't make it perform much worse. It probably doesn't.

The solution is then to stop putting dye in the coolant. This is not a solution that would be recommended by a group that makes and sells (high quality) dye for watercooled computers.
