I think the main benefit is low cost (I use 5-10% in DW) for excellent corrosion and biocidal properties. It's not a simple surfactant. (somewhere around here i have a pdf spec sheet on the stuff).blinksmiley.gif

Next time you refill your loop why not do some tests for us, and throw up before and after pics/numbers? It would be simple enough. You wouldn't even have to drain your loop, if you measure how much Water wetter before filling the loop. When it's time to switch from pure distilled to WW you could simply drain X amount of coolant, and add X amount of WW. biggrin.gif

If you ever do decide to some before/after tests, do us all a favor and throw up a thread about it. I'm sure there would be a ton of people interested in it.

For now wink.gif ......... How ever things always change smile.gif

But one of the most common comments I have read repeated over an over again is that mayhems aurora is only for shows and it will clog ya system and all of the particles will settle out within 48 hours requiring ya to spend hours cleaning ya rig and tossing components.

DISCLAIMER: I am not recommending use of this coolant in anyway outside of the manufacturer's written instructions......

However, may people have used it for months and their PC's are not piled in the trash bins. And as for settling out ..... here's a start up after a 5 week shutdown .....

Coolant was left in for 8 months. Now again, I'm not saying use it in anyway outside the manufacturer's recommendations but the "sky will fall" hysteria helps no one and is simply not supported by real world experience once other factors (i.e. plasticizers) are ruled out. There's no single right way of doing things...... water cooling is a balancing act between three competing goals.... performance, quietness and aesthetics. Push in one direction and ya give up a little in another ..... so what ? Pick what works best for you. Yes, I enjoy steer people along to help them avoid "real" problems but it's really OK if someone doesn't agree with me and does something different.

Mayhems said he's seen it run in systems for over a year without settling, but the problem is it's a VERY high maintenance fluid. Aurora really needs to have a liquid cooling loop designed, planned, and built around the fluid. The aurora in the video started back up again because the pearls didn't settle in a dead zone. The nano particles don't just disappear, they settle in all the crevices and cracks around the loop. This includes compression fittings, radiators, deadzones, etc. A month or two back I saw Mayhems post a picture of the new Aurora + which uses 30% smaller nano particles, causing them to stay in suspension MUCH longer, but who knows when that's going to be out. It needs to be tested, then probably revised, then tested again, and etc.

It should also be remembered that aurora IS a specialty liquid. This thread was more oriented around the standard coolants, and why so many people avoid them as opposed to pure distilled water. There ARE lots of notable problems with lots of different liquid coolants. Off the top of my head I can say FluidXP and Primochill premixes, as well as their dyebombs all have pretty damning issues.

Other coolants such as Fesser, Mayhems, and EK (off the top of my head) all work well.

Again, my intent was not to discuss the merits / issues with using Aurora coolants ..... merely to point out the dichotomy between what we "read on the internet" (often parroted from what the some posters themselves"read on the internet) and "real life". Direct experience is welcome knowledge but it has to be recognized that few of us have the testing capacity to determine actual cause.
