purple ice.
 

I have recently heard from someone who had some purple ice foam in his system, cause pressure and caused a leak. The corrosive mixture did his desk no good at all.

Has anyone else heard about this before or was this person just unlucky.:shrug:

i've never heard of it, but at the same time I haven't heard of very many people using purple ice

It has been a lot on another forum a looked at - Hardocp I think.

Hey TiTch, I just spoke to Danny from Dtek customs, and supposedly purple ice forms some type of gas when you first use it, so it must be bled longer than usual on first use. At least thats what he said :D

PurpleIce forms a coating on aluminum... durring this process gas is released... this should go away after a few days (once the coating is thick enough.

the coating is basically an anodizing to stop corrosion.

Redline also does this, but probably half as much.

i have a VERY long post regarding this. ill get you a link to it

here is the link:

if you are gonna try it out and see if you can get bubbles for yourself, remember that the bubbles are VERY fine and i have only seen it happen with aluminum.

Also this will only happen with NEW aluminum blocks that are NOT anodized. (unless of course you scratch off the coating)

Thanks for the help.

oh and if you didnt read through that post... one important thing when using fresh aluminum and redline/purpleice
its your discretion if this is good or not....
when the aluminum is being coated... the bubbles form on the aluminum, and they kinda stick to the aluminum and cause very small pitting. this only happens when the bubbles are in STILL water, and they are left for many hours.

now this pitting could be a good thing because it adds to surface area

if you dont want the pitting to occur (it is very very small pits.. but if you think its bad...) then just leave your pump on for 2+ days, that way the bubbles cant stick to the aluminum.

Thanks again and yes I did read the thread - all 9 pages of it. Oh the delight of having broadband.:)

Just a though - as the cemicals in wetter water is in antifreeze I gather, does this mean that when I put santifreeze in my new peltier system I have to be careful of this happening.
