Where to buy a Tolyltriazole inhibited anti-freeze for coolant?

[Nicholas Peyton]

I'm talking about getting the chiller to cool CPU and GPU to at least -15 degrees C.

Maybe more if possible.

Edited twice: \/

The more research (and digging I do) the more a Tolyltriazole inhibited Ethylene Glycol makes sense for the anti-freeze / anti-corrosion coolant mix.

The propylene probably does lubricate more but the higher viscosity reduces the thermal performance.

Another benefit is less strain on the pump (the thicker propylene will put more stress on the pump).

I'm not sure which one allows lower temps (before freezing)... or if they're both the same in that respect...

The more glycol it has the worse the thermal conductivity. So ideally I'm looking for a mix with *just enough* to give temps down to -15c (without freezing). That shouldn't hurt thermal conductivity of the water by more than 3-5%.

And yes I know that about the condensation; as I said in a previous post on the thread I've got other digging going on regards to finding the best insulator for the GPU (specifically something that I'll be able to remove easily. The 'ease of removal' is my number 1 priority in finding the right product).

I could just go fuck it and stick anti-freeze in and wrap my card up, in the first thing I come across, but I want everything I do to be easily reversible.

Easily reversible = less scary
and also less of a cash commitment! So more likely others will follow up with a similar set up.

Could even result in a formation of a -20c water chiller club, eventually, in future

I tried to get some help from a club called "the subzero chillbox club" a few months ago before I got the chiller, but they didn't seem interested in sharing any info with anyone (on an interactive basis) who wasn't already up and running.

Hence my reason to go with the water chiller instead. A totally different concept.

why don't you just use ready made coolant most are rated for -15c

http://www.performance-pcs.com/thermaltake-coolant-1000-transparent.html#Specifications
DO NOT USE ethylene WITH PLEXY loop parts this means el cheap clear plasic pump tops cheap blocks with windows reservoirs ... make sure its good quality acrylic or it won't hold and you will have a mess and a bunch of dead hardware

ethylene eats cheap plastic for lunch

joe from @ModMyMods recommended this additive

[Nicholas Peyton]

never knew that okay hmm thanks

Thermaltake Coolant 1000 Transparent, wow... now we're onto something

 

[OneMoar]

I really don't like ethylene because its toxic and it will eat some forms of rubber and plastic
proplyne isn't nearly as corrosive

see my edit

Edited:

aye, that link is excellent (the one u gave me)

Seems I may have been over-complicating this and looking too hard. I'm actually surprised there are things already available. But it looks like Mayhems have actually done 1 or 2 ventures into glycols already which is promising <--- learned that from the link OneMoar posted

I've checked out both links thanks.

On the performancePC one its listed as propylene on one page but on the 'specs' page its listed as ethylene which is a bit odd. I'll have another look maybe get in contact and see what they say.. might of just been a typo on the site.

The second one (the mayhems one) it says its based on Ethylene and is suitable for re-circulating chillers down to a staggering -50 but they also list it as 'non-toxic' which doesn't make sense...

Anyway those are two great sources thanks for all your help. Thanks ++

I use Carquest Global extended life automotive anti-freeze in my chiller loop with a 70% water/ 30% AF mix, It works really well down to -25C and still flows pretty good with a cheap made in china pump.
I've had it running for a while with copper, aluminum, brass, nickel & steel in the loop. No problems at all. Not sure if it uses ethylene though, doesn't say anything on the jug.

You running subzero?

Thanks for reply

P.S. nice insulation btw.. what is that?

*Most* antifreeze is made from ethylene glycol, but it can contain other chemicals or ingredients, such as propylene glycol, ethanol, methanol and isopropyl alcohol.

Not 24/7, that's my dedicated chiller for overclocking. Coolant drops down to -25C and the 4870 in the pic was reaching 0c @ 1.45V under load with a (terrible) bykski gpu only block.

The insulation on the tubing is just foam plumbing pipe insulation. GPU insulation is paper towel.

that is janky as hell
also looks like the gpu caught some form of space rabies between the green coolant and ice/foam

Impressive mate I see you've got some notable overclock achievements there

Would love to see more pics of some of your stuff

Almost off topic but it is Antifreeze

 

[exodusprime1337]

I've been using nickel plated blocks for a long time. A good clean block with a bit of biocide and water wetter with distilled water has never ever served me wrong. Changed out water ever 6-8 months and block remains quite clean and gunk free.

 

[uuuaaaaaa]

I will leave this here, may be useful for someone! (I am aware that you are looking for a specific compound )

 

[Arctucas]

Explain.

Search 'silver killcoil'.

The Watercool rep on OCN chided me for using silver in my loop. Silver apparently causes bimetallic corrosion of the copper components.

However, I have seen no cooling performance degradation over the last six years.

hes going sub zero kids he needs some sort of anti-freeze

Thank you

You're right.

Must be something that doesn't eat plastic/rubber and has corrosion protection for copper/brass & nickel.

Different chemicals protect different types of metals. Some for example, protect some metals but would leave other metals completely venerable.

Also the thermal conductivity can't be too badly effected. Some chemicals are 10x worse than water at absorbing heat. Some are only 5% worse


minus -15 degrees Celsius would suffice

And good isolation.

My Chiller should be here next week, i won't try to go sub zero but at least 0c

With -1c Td i could give it a try.



Those are the temperatures in my Room.

 

[Nicholas Peyton]

You must be freezing your balls off in there lol

 

[FireFox]

You must be freezing your balls off in there lol

Hahahahah.

We have had this morning -15c

10c in my room would be great.

 

[Mr.Scott]

You're totally over thinking this.

No damage to any of my stuff. Good to -30c.

 

[Nicholas Peyton]

You're totally over thinking this.

That has occurred to me a little.

But...

You're probably thinking:
"why doesn't he just slap a cheap copper, universal GPU block, on"
then
"use standard anti-freeze" & revert back afterwards."

I could, true.... But wouldn't it be nice to be able to have it all set up so I don't have to #### about.

-I could run at 20c (normal ambient) on Monday.
-Do a -20c subzero run on Tuesday
then
-just use the Chiller at a standard 10c on Wednesday. No drains, no refills. No hassle.

Nickel, apparently can't even withstand alcohol. And I've got loads of it in my loop... (nickel)

Imagine how convenient it would be if water didn't actually freeze until -20 . That's what I'm aiming for.... a coolant I can use all the time for both. Without having to do extra drains/refills..

 

[Mr.Scott]

Garbage. I have nickle in my loop also. I've used this for years.

How long do you leave the anti-freeze in before draining and returning to distilled mix?

 

[Mr.Scott]

I never change it. I run it all the time.
Only time it gets changed is when I have to clean the loop, even then I just use new antifreeze.
