Mayhems Pastel White Splitting

This is great news! Shame its happened but great they have looked into it and identified some kind of issue.

Typically I just pulled the trigger on a blitz kit, some clear coolant and more TIM. I figure if they do have an issue they may offer FOC blitz kits and coolants :(

Hmmm, not sure if I should even open the unopened bottle of premix pastel white that I've got.

I’d be very hesitant to add it back to my loop considering the work required to strip it all down and clean it should the worst happen. Up to you really, you could pour the mix into a bottle and leave if for a while to see if it’s splits. Probably the best thing to do though is to drop them a line and ask for advice on how to proceed.
 
I raised a ticket straight out, initially asking for advice on the blitz cleaning kit and whether or not the part two would clean the gunk out of my tubing.

Support has been great, new materials will be here by Wednesday.

X1 clear concentrate I believe they are sending, together with water and a blitz kit.
 
My premix was March 2020.

The mayhems owner has said it seems random at the moment so I take from that it’s happening to some but not all bottles of the same batch. He’s been opening bottles from his stock to determine this.

Hoping you don’t face the issues we did, fingers crossed.
 
Yes mate it did, did yours?

They sent me -

2 x x1 clear conc
1 x 5Ltr water
1 x Blitz kit

Cant fault them for sending it all out and openly admitting there may be an issue with pastels. I'd still like to use the pastel white as it really sets the build off, I'll decide if I'll ever go that way again once I've gone through the first strip down and rebuild process. TBH I cant see as I will as it took me an age to do the first build but hopefully the rebuild will be quicker.

I'm waiting on a couple of bits from OCUK and else where (I ran out of TIM!!) then I'll strip everything, blitz the rads with part 1 and the full loop with part 2 the do a refill - hopefully this weekend

How can you run out of Themal Paste? :D I must have about 2 or 3 completely unused tubes, that have come with various coolers etc. over the years. I think I'm still using the same AS5 I bought about 10 years ago.

I'm also waiting on stuff from OcUK but I think it's because one of the items I ordered wasn't in stock. I'm tempted to ring them and remove the item from the order so they can send everything else out.

It'll be interesting to see how you get on after cleaning if you do decide to put the white back in.

when I say I’ve ran out I mean I’ve ran out of the TIM I want to use this time lol. I’ve got loads of scrappy end of tubes sitting around but I’d prefer to use one type on the GPU and CPU blocks, given I’ve got to take the whole PC apart I want to do this once and once only for hopefully the next 12 months :)

So this is what mine looks like in the morning when I first turn it on.

It does however clear/mix-in when I leave it running for a few minutes. Problem or just settling overnight?

I think it’s probably ok. From what I’ve read and seen it will settle out a little when not used.

What we’re seeing is a complete separation where the white particles literally coat tubings and blocks and then do not remix.
 
Something like this? Lol

All cleaned off easily enough. Bigger issue for me is my distro plate, it’s got a film of white all over it. I’m hoping the blitz part 2 will take care of it, if not I’ll need to strip that out too, not something I fancy as there’s a mass of seals in there.
 
I’ve given it serious thought but it’s a major ball ache to do so even if there is a little left on it I’ll probably live with it for now. :(

or maybe not... lol

if I do strip it down I’ll probably chuck in a 3.2 pump, I’m finding the 3.1 at certain speeds has a really annoying whine to it.
 
This was after 3 days after a new build, I first noticed a problem around 24 hours after finishing by day 3 only clear fluid was circulating. The particles literally fall of solution and settle at the lowest points, amazingly the lowest point here was below the heat transfer fins so temps were still fine. Cleaned out quite easily though :)

Yes it’s a phantecs glacier, heavy as hell, I’ve had to put a support bracket beneath the GPU to prevent it sagging.

pastels are show fluids only arent they?

EDIT - checked website, seems they suggest 2 year lifespan in a loop. i bet they havent fixed the flaw they had years ago that made it change. when asked they will likely state pastels are just a show/temporary coolant.

They still state 2 years, Too Tall and I have had lengthy discussions with Mayhems, who've been really good it has to be said.

Outcome for me is the same as Too Tall, Mayhems sent a Blitz kit, plus clear concentrates plus water.
 
I think everyone expects issues with pastels given enough time, difference here is too tall and I saw this in only hours and days. Mayhems looked into it and found a random problem with all pastels so removed them from sale.
