Testing a non conductive fluid

Anyone have any suggestions of how to properly test if my coolant is still non-conductive?
 
Well I know I need something to measure it, but I'm really asking is what voltages and currents should I be testing at.
 
Does anyone know the highest voltage in a computer? Is it the 12V line of the PSU?
 
Correct me if I'm wrong, but once the fluid touches metal parts, you have conductivity, such as the cpu block.
 
Get a multimeter, pour some of your coolant into a small glass. Stick the two probes on either end of the glass and measure the resistance of the liquid.

I'm referring to electrical conducitivity...

Me too, from all that I have read, once your fluid hits the blocks, if it leaks onto your equipment, your still in the same boat, USC without a paddle.

If I'm wrong, again correct me, but I took this from the reading over at XS
 
If I'm understanding correctly, you want to check the conductivity to ensure if you have leaks it won't short out your components. Even though you add*non conductive* fluids to the distilled water, once it pases the blocks in your loop, it will become conductive from the *metal* which will still short out your components.
 
03) What Type of Water Should I Use?

posted by MaxxxRacer: The only coolant I reccomend is distilled water. It has the best cooling properties short of exotic fluids created by 3m (cost upwards of 1000 dollars to fill your system), has relatively low conductivity compared to regular tap water, and is cheap. There is NO need for all of those so-called non-conductive fluids as NONE of them actually are non-conductive. They have moderately higher resistance than distilled water, but will still dammage sensitive electronics.

This is what I was explaining.

Higher resistance than tap water. You get to play Mr. Wizard, unless you already know the resistance of your non-conductive coolant.

If your going to quote crap from XS you need to tell people what their thing is. They are completely dedicated to getting the last tenth of a degree in cooling capability and anything else isn't worth talking about. So to them distilled water makes the most sense.

I remember going to the Pomona Computer Fair and one of the CEO's from some company that made this non-conductive stuff would put on demonstrations. His favorite demo was taking a computer PSU out of the computer and putting it in an acrylic box. With the computer running he would pour a shitload of non-conductive fluid right into the power supply until it was up to about 1/2 way up the side of the PSU. The computer didn't miss a beat...
 
So your telling me and anyone else who pops in this thread that using non conductive additives to your loop is not going to damage any components if it leaks?

I'll be more than happy to continue with the links proving otherwise if you'd like ;)

If you have a beef with others over at XS, you may want to consider keeping it there, by the sound of your elitist attitude.
 
Yeah, I've come to take comments like "Non conductive fluid isn't really non conductive" with a grain of salt for several reasons.

1) If it really isn't non conductive, you have false advertisement and a class action lawsuit on it's way.

2) The demos that I've seen where the fluid is literally tossed into the open case or poured into an open case and the computer didn't even twitch... admittedly it could be faked but then you get into issue 1 again.

3) My father just happens to be a really good Organic Chemist. He's one of the top in his company. He knows his shit, and based on what these fluids are supposedly made of he agrees that it will protect your system from a fatal shock as long as you don't contaminate the fluid. If you contaminate it, it's your fault. As to whether or not the metal components will add their own conductivity to the fluid, if the parts are adding that much material to your fluid, then you have much larger problems than conductivity. They shouldn't naturally.


The only reasons I'm contemplating not using Fluid XP or the like in my next build is because of the other drawbacks associated. Such as Fluid XP breaking down and causing gunk to build up in your system. And strangely enough, I have algae issues that don't seem to respond to the usual algaecide. I don't know if that's because of the nature of the fluid itself or not. The cooling aspects versus water are really not all that noticeable, 3 degrees of temperature difference if you are well within an optimal zone is nothing but bragging rights.

No, I didn't say that. What I did say was that I observed a demo that was pretty convincing. IIRC, it was Fluid XP but not absolutely sure on that score as it was several years ago. When it comes down to it if you do a good leak test, use high quality fittings and tubing, and have good mechanical skills then you have nothing to worry about. I take my loops apart all the time and have never had a leak yet. Did drop a glass of ice water into my computer and fried it. ;)

I don't care what most of the people at XS have to say. If you got a link disproving it, from a credible non-interested party, then I will be all ears. :)

Not an elitist attitude, I just don't like the way they conduct themselves. And no I am not going to discuss it here because that will start another flame war that is OT to this thread.
 
Well, here's the results....

Distilled: 6 MΩ
Tap: 100-130 kΩ
MCT-5: 380 kΩ

Keep in mind, the MCT-5 sample I used was from my WC system and has been flowing in it for over a year.
