Is there a rainbow coolant?

[Ruby_6]

I'm looking for a coolant that has a sort of iridescent look to it. Kind of like the rainbow look you see in oil sometimes? Something like this:

Not sure if anything like this actually exists, but it would be great if someone could let me know!

Thanks

You can dye your coolant fluid, but getting an iridescent effect? Not sure...
I assume if you can see your fluid your piping is clear? (I don't know, never seen such systems in the flesh)
Surely you must be able to get iridescent plastic piping...would that work?

Edit: I can't find any tubing, specific to pc cooling srtandards, in that oil slick effect. That doesn't necessarily mean that it does not exist. 😛

Edit 2 : small, multi coloured, LED lights...changing...very little to power, led so practically 0 heat...option?

Edit 3: this is used to make flies, for fishing...

Probably not suitable, but getting closer lol

Since the liquid is constantly moving and mixing, pretty sure there isn't a liquid that can do that.

The sheen in oil comes from the layer of oil differing in thickness from place to place. This causes constructive/destructive interference with certain wavelengths of light, causing different colors to appear/disappear. You're not going to be able to get it with a liquid coolant running in a tube which is (A) much thicker than a wavelength of light, and (B) varies considerably in thickness over a small linear area.

Likewise, any dye will just mix together and become a nondescript brown or grey.

You might be able to find some temperature-sensitive material you can wrap around your tubing, like some flat fishtank thermometers are made out of. The temp range would have to be a lot higher of course. And the coolant is likely to be so uniform in temperature that the color wouldn't vary much.

Or you can try looking at the tubing through a polarizer. Different stress levels in plastic cause the same type of color band effect, and polarized film makes these bands visible. Maybe the tubing has some inherent stress which changes with coolant temperature. If so, you could put a sheet of polarizer film on the inside of your case to make this visible (if you put it on the outside, it'll make stress in the plastic window of the case visible).

Something similar though not exactly like that with all the various colors, mayhem's aurora coolant. It's supposed to be pearlescent with some swirls in it.

You may want to read up on it some however, here's a discussion revolving around it.

Keep in mind that some specialty coolants are not really the best idea. There may be additives in them that could plug filters, cause premature failure of pumps, clog radiators or water blocks, corrosion concerns and so on. Some have really unique properties and are used in displays or show systems at places like electronics shows because they're eye catching for dramatic effect but may not be suitable or appropriate for all day every day use.

I'm not saying that's absolutely the case with mayhem's fluid but be sure to contact any specialty manufacturer ahead of time. Ask questions, confirm that it's suitable, ask about warranty coverage if there is any or not. If a product is known to cause issues during continued use any upstanding company would likely be forward enough to say so, let you know that the product is more for short term display use and to use something more stable for an every day system.
