Watercooled 780s - Page 3

All non conductive coolants becomes conductive overtime in loops. They may be non conductive to start but the conductivity transfers from the chips through blocks into the coolant. Distilled water is considered best because it is cost effective and generally easirr to clean up. As for looks, just add dye if need be unless you really just want to buy brand coolants.

This is true, but that is why you should clean any particles out your blocks before you use them and not use low quality blocks, keep your system clear of dust, and to change your fluids periodically. Same goes for distilled water especially if you are not using a silver coil or some kind of antibacterial/antifungal additive. Like I said before I personally just like the EK premixed stuff, I like how it looks and I like the thermal conductivity I get from it over distilled water. I've had it running in my system for about 3 months now and there has been no staining of tubing, my blocks, and when I had my Larkcooler rad crack on me and coolant started to leak onto my motherboard and video card nothing shorted out. That was with the coolant that was in that loop for about 3 months and had been drained out and put back in several times in that span because I have been doing upgrades upon upgrades. I honestly feel that if I had been using straight distilled water with or without a silver coil I think my motherboard and video card would have been crispy critter.

And yeah I agree distilled water is very easy to clean up, this stuff not so much. Each time I drain the loop I do it by the sink, always ends up looking like I just killed a bunch of Smurfs tongue.gif

To make it clear, I agree with you 100% on your statements because what you are saying is true.

Conductivity build up is caused by the water picking up ions from the material used to make your blocks. It can even be picked up through your tubing depending on static charge caused by friction etc.

Never meant to cause offence or anything, I meant you were missing my point that custom coolants have a content value of around 90 to 95% distilled water so it's pretty much one in the same thing. It doesn't matter what you buy to put in your loops, you are getting the same level of conductivity after about 3 days.

Ah alright I get what you were trying to say before. I wasn't quite sure what you were getting at before but thanks for clearing that up a bit. thumb.gif

I would like to know though, based on the EK Premix stuff it seems to have some different proprieties than your run of the mill non-conductive/distilled water coolant.

Whereas what you say is true (about the ionization of the water/coolant), out of curiously though if the coolant/water has already be deionized does that still remain true about the coolant/water becoming ionized again?

I ask this because when one of my 7970s took a bath in the stuff energized it didn't bother it. If the coolant had become ionized again then it should of by all accounts fried it correct? This had also been the same coolant circulating in my loop for around 3 months at this point when this happened.

Also I want to thank you for actually taking to time to really explain what you were trying to say to me from before. thumb.gif

No problem smile.gif

It's true that some coolants start with less conductivity than others and a bit less than distilled water. The issue is that generally regardless of mixture the ion build-up is quite a quick process based on material exchange with your metal components. Some coolants do coat the internals of blocks with it's additives which help to reduce this but in a lot of cases it can just ruin blocks and cause really short service intervals to block fins and pumps which aren't worth it. I think you were just really lucky with your 7970. Generally water that is de-ionized still retains quite a low conductivity level after quite a bit of time in a loop (I mean low when compared to something like tap water). The issue is that no water based coolant remains 100% non-conductive. thumb.gif

^^^ this

The only non-conductive coolant is something like fluorinert... and if you think that your gatorate-coloured low-conductive "liquid" was expensive to start with... look up the $$$ per ounce of fluorinert biggrin.gif

rule of thumb: distilled(demineralised/de-ionized) water + silver coil (or ptnuke) is the cheapest and best performance
and stay away from nickelplated EK blocks smile.gif

Why, is there something wrong with the nickel plated EK Blocks?

That problem was solved if im not mistaken some time ago. They had a big "recall/scare" on all of there nickel plated blocks that started flaking and just basically ruining loops. This however was like 3 years ago? If I am not mistaken. There has been no word of it ever since. It has left quite a distaste for their nickel plated blocks ever since for some.

And EK was even blaming their customers, LOL

But those days are long over. Their blocks are OK, now.

yeah that's water under the bridge now. I had their nickel plated... everything lol, at the time and it ruined my rig. They paid for the whole thing to be replaced, even the case. These days though their blocks are quite possible the best you can buy.
