As many in the club here are contemplating or migrating to watercooling for better OC;s I wanted to share my findings of years of watercooling and hope it helps those confused by the extreme differences posted .
You may run into a lot of warning that are from one end of the spectrum to another. A basic rule is not to introduce aluminum into a copper based loop. A bit of an explanation below.
Copper, Silver, and nickel have very little reactivity with each other (electron transfer) as they are all transitional metals. b) close to each other (atomic weight). So in other words they do not create a destructive environment when used together trying to neutralize their differences in electrons. ( at least they are close enough where for practical purposes (say in our water loops) that they are close enough that a silver coil in a system would be very slow and negligible in a practical application.
Aluminum on the other hand, is not a transitional metal and has a lower atomic number (lower number of protons and electrons) and creates an environment of much more active ionization when put in the same environment with transitional metals that are closer in atomic weight/proton/electron count, pulls electrons from the other metals IE damages them.
Transitional metals/Abbr/Atomic weight
* Silver 'Ag' 47 Transitional Metal
*Copper 'Cu' 29 Transitional Metal
*Nickel 'Ni' 28 Transitional Metal
Non-Transitional metal/ABBR/ Atomic Weight
* Aluminum 'Al' 13 Non-Transitional Metal
just doing some reading about it quite a long time ago about non compatible metals 'eating/corroding/ ionizing (stealing electrons) or otherwise breaking each other down.
assuming you have made sure that you have limited the metals exposed to the water in the loop.
1) If you keep the main components (the vast majority of the metal) it to transitional metals
2) Limit the Non transitional metals in the loop to the Tin (Sn) in the solder. the Copper (Cu) and Zinc (Zn) comprising Brass (both transitional metals)
3) Do not introduce Aluminum to the internal system.
The practice would be (for myself) this is what I based my loops on. I use a Silver Coils and Distilled and thats it. I have not observed any ill effects on any part of the metallic loop. I keep an eye on my loops particularly on smaller edges and thinner areas like micro fins for signs of ionization and have seen none sticking to my policy above. Let me qualify that as I have not observed any effects that are a rapid or immediate harm to functionality. Some ionization is always taking place, I am speaking of to the degree that will functionally shorten the lifespan significantly or cause premature failure.
remember that additives and such can change the Ph levels and such. I have not included the effects of those as I rather despise dyes, colorants, pastels etc. This is regarding those like myself that prefer the use of distilled water and the use oif Silver as an antimicrobial preventative.
Hope this helps some of you making the transition to watercooling. **** This is my findings and research so I am merely sharing the results of putting this in practice in my watercooling.****
