Can anyone rate the primochill Typhoon III?

BoxGods. Stop right there. The level of corrosion that can destroy a block will probably be invisible on a boat. Now, I'm posting to prevent this from turning into another 20 page epic about corrosion. Here's the bottom line. Galvanic corrision WILL happen in a mixed AL/Cu loop. At what pace it happens is determined by the additives and some other factors such as temperature etc etc etc. BUT... it WILL happen. Sometimes several orders of magnitude less than if you were careless. But it WILL happen. There is no solution to galvanic corrosion on earth that will prevent it 100%. None! Its scientifically impossible because there will always be SOME ions that will not get touched by additives. Even if you apply a reverse voltage, there still be some corrosion. It will be small.... but it will happen.

Your example of 300 series steel is a bad example. It is actually a very noble alloy. Far more than mild steel.

Like I said...some people are going to freak out lol.

And my example of the 300 series is an EXCELLENT example. The fact that it IS a very noble metal is the point. The further the two metals are apart the more dramatic the effect. The 300 series stainless is much more noble then the copper in your blocks so the copper would be the anode and corrode rapidly...if there were a metal to metal contact.

You guys can read it for yourselves.

There are tons of links online that explain it in detail. The facts are that there MUST be an electrical connection.

Yes there WILL be some corrosion in ALL systems--the difference we are discussing is the difference between a few months and 10 years though...far beyond normal service life on any water cooling component.

Sorry buddy... but you don't quite understand it. If the Steel is a noble alloy it means very little corrosion of it, and ANY other metal in the loop. .... the very reason why it IS used in pumps. To corrode it has to be an active metal. Mixing an inactive metal (like your hard steel example) is like mixing plastic with water and copper. ie no effect. Your statement of the farther they are apart = more corrosion is not entirely true. They have to be both active metals.

The electrical conductivity can and will be provided by the water in the absence of anything else. The current that passes through the water to have the effect of corrosion is so small that it will happen.


You should try a Zalman reserator with a copper block and tell me there is no corrosion. (I had one with a copper, low restriction GPU block)... the residue settled down the bottom of the reserator itself.

Guess we will have to agree to disagree as I have seen galvanic corrosion between two grades of stainless. I am going to go with the experts (and nature) on this one. No circuit...no galvanic corrosion. The more noble a metal is the less likely it is to be the anode (the metal that dissolves/corrodes rapidly). Stainless can STILL be the anode if the other metal is even more noble. The water does NOT make it a circuit...

I will again point to this link:

Under the three conditions needed for galvanic corrosion number 2 is:

Condition 2. The metals must be in electrical contact

The two different metals must be in electrical contact with each other. This is of course very common. The two metals can be bolted, welded or clamped together, or even just resting against each other.

Under the how to avoid galvanic corrosion section near the bottom of the page it says:

Prevent Electrical Contact.

It is often practical to prevent electrical contact between the dissimilar metals (removal of Condition 2). This may be achieved by the use of nonconducting (eg rubber or plastic) spacers, spool pieces or gaskets, perhaps in conjunction with sleeves around bolts. For the same reason a gap may be left between galvanised roofing and a stainless steel down-pipe.

Again. Not to get this going into a big argument as the only thing I would fight for is your right to disagree, but without a circuit there can be no flow...and the spice MUST flow =)
