Pure-Sil Biocidal coolant

[iandh]

I like the biocide piece, but I don't understand what all the fuss is over electrical conductivity? I understand it's one way to measure purity, but what's in there causing the high reading? Is it something that is detrimental to the thermal performance in any way?

Has anyone measured thermal conductivity after being in the loop for a week straight, one month? Can you measure the difference between the purest water and your worst grocery store brand?

From what I understand there are only two properties that matter regarding thermal performance:

Volumetric Heat Capacity - Is the measurement of storage ability
Thermal Conductivity - Is the measurement of transferring heat

How does electrical conductivity relate to thermal performance, and why is it important or even measured?

Just curious why all the fuss on electrical conductivity...I plan to keep buying my horrid grocery store brand until someone convinces me otherwise..

The initial conductivity measurement determines the purity of the water, and the secondary measurement determines the ion content.

As for horrid grocery store water, it can be either superb, or awful. That's basically one of the services I offer with this product... I'm taking a calibrated purity test meter and ensuring that this water is of a good quality.

Typically distilled water is very pure, but I've gotten some VERY bad batches. I'd say less than 5% of distilled is what I'd consider poor quality. Most is very good.

I thought electrical conductivity mattered so you are less likely to zap your gear if you get a leak

It can, but in my case I'm only worried about conductivity for quality control. Pure water ensures there isn't crap to deposit in your loop, and ensures I have a good clean starting point to add ions. That is really all I'm worried about as far as conductivity and this coolant goes.

Actually, I am curious Iandh if you put so much silver into the solution doesn't that make the fluid conductive so if it leaks onto your board you could cause a short to happen?

I don't disagree that over time all water based fluids will become conductive, my question is whether or not his fluid starts off that way. I haven't had a leak occur after I have leak tested and therefore I am concerned with the conductivity during the initial install phase, not 6 months down the road.

It's definitely more conductive than distilled, but no more so than any other coolant. Even distilled will pick up contaminants from the loop and almost instantly lose its non conductivity upon installation.

People are very concerned about purity for non-conductivity, but in my case I'm just worried about certifiable quality and loop longevity.
