As the time comes for the LGA 2011 IVY-Xeons and new Radeons in October, i started on doing a bit of research regarding watercooling.
Like what tubing should i use and what liquid is best concerning maintenance and performance.
So here is what i learned.
1)First of all the tubing has to be plasticizer free, if not, the plastic will wash out with the water, and not only you would have to swap the water ofter, but the block will also clog in time
2)There are a lot of liquids out there one can buy for a watercooling loop. Here is simple. I will use in the loop the same liquid i drink every day. Since i have an apparatus that makes this liquid in sufficient quantities for me to drink as much as i like every day, i will have no problem with that. That liquid is distilled water, and coming from a doctor, this water is the right water we should be drinking. As an off topic, distilled water cleanes your body, normal water clogs your body, distilled water promotes health, normal water promotes disease
3)Since i also have a TDS meter at hand, with which i test my drinking water, i could theoreticaly test the water in the loop after a certain amount of time for total disolved particles. To see how its cleanliness holds up with time.
Basically, distilled water has a TDS-Rating of 0 (TDS=total disolved solids) I recently aquired a more performant TDS meter that converts the TDS rating in conductivity, in MicroSiemes/m. As you know (or not) distilled water doesnt conduct electricity. I tested now a sample of distilled water and it showed a conductivity of 5.5 µS/m. This is done with the advanced Tester. This 5.5µS/m shows as a TDS rating of 0 on a cheaper Meter that i also have. Freshly made distilled water shows a conductivity of between 1.2 and 1.5.
4)It seems the best bactericid is Silver and the best option would be to have silver in the loop some how.
There is a CPU water block from aqua computer that is made of sterling silver, that 92.5% pure silver. That seems to be not enough. Thats good since thats 250+ Euros a pop.
Another solution would be to have one or more silver bullets in the loop like this one here
Another solution would be to use silver plated fittings. It seems there are silver fittings from bits power.
Check that here
Now since distilled water has extraordinary dissolving power (thats the reason its so damn healthy, in fact, distilled water can cure diseases that are thought incurable by the modern medicine), Silver ions will be swimming in the loop liquid, and these silver ions will make the distilled water in the loop bactericid.
Since conductivity in a liquid depends on dissolved particles, in this case ions, i could test the conductivity in time of the liquid inside the loop, to see how much silver ions will be in solution. Provided these silver ions will be the only thing that will be dissolving in solution.
Since there are no radiators with silver on the inside, and since i will be using AMS Aquacomputer raditors with pump made of copper, copper ions will also dissolve in solution.
In any case, it is said the bactericidal propreties of the loop liquids are only going to improve over time, since more and more silver ions wil be swiming in distilled water. That is its conductivity will also increase over time, probably enough to make a short circuit if liquid will spill on some unprotected components. So you would also want to be careful, even if distilled water does not conduct electricity.
To my knowledge a TDS Rating of 1 or 2 doesnt conduct electricity, and since a rating of 0 showed on my TDS meter as 5.5 µS/m ( i dont know what would 1 be untill i actualy test a water with rating of 1 with the more sensitive meter), i would suppose a higher rating of 10µS/m or 20µS/m would still not proper conduct electricity.
Therefore is imperative to select a tubing that does not disolve in distilled water over time, or in other words, that does not leak any substances what so ever.
I have therefore found 2 candidates, plasticiizer free tubing, one is the Tygon E-1000 wich is softer, and the other is Tygon 2475 High Purity tubing wich is harder. Still havent decide on the diameter but i suppose of bigger tubing would be better for the flow of the liquid, whereas probably thinner tubing would be better for short tubing that needs to be bended, at least thats what i imagine it would be.Features/Benefits of Tygon 2475 High Purity tubing:
• Exceptionally Low Absorption and Adsorption Compared to Silicone
• Smooth Inner Surface Inhibits Particulate Entrapment
• Environmentally Safer to Dispose; Reduces Cost of Disposal
• Highly Resistant to Aggressive Cleaners and Sanitizers
• Plasticizer Free
• Meets USP Class VI and FDA CriteriaLow Absorption/Adsorption
Maintaining fluid integrity during transfer is critical in numerous pharmaceutical and
biotechnology applications. Loss of fluid through migration into the tubing walls can
cause inconsistencies in final product results. TYGON® 2475 High Purity Tubing is hydrophobic
and will resist the absorption/adsorption of aqueous fluids. This reduction in absorption/
adsorption minimizes the risk of fluid alteration in single or repeat use applications.
As a side comment here, it states that the tubing is hydrophobic. For those of you that dont know, that means it repells water. A better explanation would be to watch this video, where a hydrophobic nano-particle paint is painted on materials, making them imunne to weatness. Please not how water moves itself on these surfaces, as it seeks a non-hydrophobic surface.
Probably that would have some benefit to the water flow as well.

Until now, clear, flexible tubing was restricted from use in many applications due to
concern of plasticizer extraction. TYGON® 2475 High Purity Tubing is entirely free of any
plasticizers. This unique tubing uses the latest in polymer technology to provide an
entirely clear and flexible tubing choice for sensitive fluid transfer applications.Smooth Inner Surface Improves Sanitation
Analysis has shown the inner surface of TYGON® 2475 High Purity Tubing to be smoother
than other frequently specified flexible tubings. This smooth surface inhibits particulate
entrapment onto the tubing wall and reduces the potential for bacterial growth
A smoother fluid path also improves fluid flow characteristics
by reducing surface area and lowering adherence of fluid onto the tubing wall.Reduced Disposal Concern
TYGON® 2475 High Purity Tubing is also unique when it comes to disposal. In today’s
environment, incineration is commonly used to dispose of contaminated materials.
Many tubings actually contribute to this problem by releasing hazardous byproducts,
such as chlorine, when burned. TYGON® 2475 tubing only releases carbon dioxide and
water when properly incinerated.Superb Chemical Resistance
TYGON® 2475 High Purity Tubing is virtually unaffected by chemical sanitizers and
cleaners. As a result, it can be cleaned repeatedly without decreasing its service life.
The non-wettable surface of the product facilitates complete drainage of fluid
during the cleaning process. TYGON® 2475 has a masterfile with the U.S Food and
That beeing said, i thinks i will be using the Tygon 2475 Tubing, bits power silver plated fitting, and copper radiator for water cooling.
