Cpu AIO Coolant mix

[JerryBond]

Hi,

 

I'm using Arctic liquid freezer II 420 and i suspect it may be affected with the issue:

"In certain units, the gaskets were not sufficiently vulcanized causing a chemical reaction to occur between the copper cold plate and the gasket. This reaction may lead to sulfur residue and copper plate deposits. If this has happened, it can lead to a reduction in cooling performance and potential loss of cooling liquid."

 

I plan on checking if i'm affected since i bought at the right wrong time and I'm already planning on how to fix and if i do decide to empty all of the liquid, wash the interior with distiled water and replace with a diy mix... But how to make a good cpu coolant mix?

As a chemist i have access to ultra pure water and other chemicals, and want to know what is best mixture for the coolant solution.

I've read people would use antifreeze or propylene glycol, but in what ratio?

I could also add a bit of methanol in there also, or whatever else you recommend.

 

Thanks for any help i get on this.

this is non-fixable. It will just happen again if you do that. You need to return it to Arctic and they will send you a brand new one without the issue.

I bought through amazon, is it still possible?

 

I saw in gamers nexus video that they are sending out repair kits also, so i could do it myself too.

 

He also fixes it in the video with said kit

yes IF you have the repair kit (exact gasket, etc) you can fix that- i’ve seen the video- just it’s not fixable by just replacing the water

To paraphrase Linus, the best coolant for water cooling is water.

 

Joking aside most additives are kind of silly for most applications.

 

Your AIO has no transparency so any coloring is pointless.

 

Mixing in antifreeze might make sense in some edge case where your pc is exposed to freezing conditions. Maybe you live in a cold climate and go to outdoor winter Lan parties or leave your pc in your car overnight when traveling? but there's a trade off. Antifreeze has a lower specific heat (ethelene glycol 2.27, propylene glycol 2.73) than water's (4.186). so you'll trade heat capacity for the feature of being resistant to freezing. I believe a lot of AIO's make this choice for easier shipping/storage. The ratio you mix depends on  what temperature you want freeze protection down to.  https://www.doe.mass.edu/mcas/pdf/2011/225502.pdf

 

In an AIO some anti-microbial additive likely makes sense as you'll be unlikely to do frequent loop drains and maintenance on it and again have no transparency to be alerted to gunk buildup. Plus there's no real downside to adding a few drops of iodine to the loop, other than needing to obtain said iodine or other anti-microbial agent.
