Not looking to go down the road of it's not needed or shouldn't do it. This is an aio (h100i v2) I'm going clean and refill. I pick it up on the cheap. Its working "ok". But nowhere as good as it should be and after many temp issues I'm going to investigate inside the loop.

 

Im just wondering what the best biocide  and anti corrosion for this would be for when I refill?

 

Was going to pick up primochill utopia but figured I'd ask in case there is something better.

EK CryoFuel.

Won't work for AIO. AIO uses aluminium rad.

AIO isn't supposed to be refilled. If you somehow find a way to open it and then able to seal it again. Then the coolant inside is a mix of distilled water and propylene glycol.

 

Primochill utopia won't work with aluminium radiator and copper water block. Most AIOs use aluminium radiator to reduce cost.

yes i know it isn't suppose too. yes i know its mixed metals. are you recommending me to use DW and PG blend instead of.....Utopia or Cryofuel?

any reason why you would choose this?

Neither contains propylene glycol. Won't work.

Why would 2.5-5 % Sodium 2-ethylhexanoate,<0.02 % Methylisothiazolinone, and 0.1-1% Methyl-1H-benzotriazole not be suitable for a mixed metal system? Since you two seem to know more chemistry then I do, please go ahead.

 

If you prefer a more toxic route, automotive coolant (High concentration of ethylene glycol with some really nasty shit with diethylene glycol and sodium hexanoate (note, same anti corrosive as EK CryoFuel) would be functionally the same. Just more toxic, and more suitable for a wider range of freezing temperatures that a car may experience. For a PC, it just makes handling more annoying.

For the sake of OP, I should clarify to definitely not use the opaque (solid) cryofuel, and only consider using the transparent uncoloured one.

I don't know shit about chemistry. I use EK CryoFuel clear in my own loop. Works great, much better than distilled water with biocide plus anti-corrosion(from Mayhems).

 

I know EK CryoFuel won't work with a mix of copper and aluminium, because I tried it already. You will be lucky to survive a month before the corrosion build-up blocking the micro-fins on the cool plate completely.

Don’t know what metric you used to ascertain that CryoFuel is better than Mayhems, but whatever, guessing you had (User) problems with the Mayhems or it’s just a feeling thing.


Why did the aluminium come out of solution again? Apart from the fact that a month is incredibly short for a protected system. Something doesn’t seem right to me and unfortunately have to guess that there was some user error here.

I still have a bunch of fittings coated with "green" stuff. Since switching to Cryofuel clear, both PCs only require routine once a year maintenance.

 

Guess whatever you want.

That’s copper oxidation, not galvanic corrosion.

Have you watched Gamers Nexus opens the Enermax Liqtech II cooler? It looks like that but to a lesser degree.

I have seen it, and then would raise you the question why the gelling of glycol (formation of poly ethylene/propylene glycol) is similar to CryoFuel.

I don't know what exactly the build-up was. But I know there were some green, white and black solid stuff build-up in the micro-fin area. And the whole loop was coated with those green-white thing. One loop used hard tube and the other one use EK ZMT tube. So, it wasn't plasticizer. I had the same problem with both loops.

 

I'm not new to water cooling. I build quite a few loops for myself and others.

After talking to some people over at OCN i think i'm going to use some PG. Was considering mixing PG, Utopia, and distilled water. Would this be a no no?

Do not mix and match fluids together everything in the propylene glycol will be enough for mixed metal given the proper concentration.
