You should start a tread "Thermaltake Bigwater 760 (caution) " , if it's not too late return it to microcenter ..... the rad is in aluminum, this is a bid NO and No it react with copper, it's why Thermaltake fill it with a lot of Ethylene Glycol , pay attention to that stuff it's poisonous like hell. I have an old Bigwater, this is not efficient at all for a single CPU, don’t expect to add more thing to the loop. I’m not kidding look I test it :
Mine is old, I have it since few years, but I check your's and it's still Aluminum, just told your H100 was giving better results, it's true anyway .
what they change, from the pic and spec, it's the same pump, the pump is actually quite good , I use one from anohter kit in one of my build since 3 years, the also have a reaostat for the pump speed I guess, and they have a new universal block for the CPU, the rest look the same, keep in mind I don't search I just look, so it's not really reliable.. lol
look here the spec of the rad .... Aluminum

I found this while researching why the corrosion occurs.
The oxidation process that gives copper its characteristic green patina is a result of exposure to an acidic atmosphere. When acidic moisture comes in contact with exposed copper surfaces, it reacts with the copper to form copper sulfate. The acid is neutralized during the reaction with the copper. This patina eventually covers the surface and adheres tightly to it, thus providing a protective layer against further weathering.
Corrosion:
All metals have a property called nobility. It is a measure of a metal's resistance to corrosion when in contact with another metal. A greater relative difference in nobility between the two metals in contact indicates a greater corrosion potential. Table 1.1.4 ranks the most common metals used in construction in increasing nobility, called the galvanic number.
Table 1.1.4 - The Nobility of Common Metals
When dissimilar metals are in contact with one another in the presence of an electrolyte, galvanic action occurs, resulting in the deterioration of the metal with the lower galvanic number. The electrolyte may be rain water running from one surface to another, or moisture from the air containing enough acid to cause it to act as an electrolyte. In our case its the water systems coolant.
Since copper has one of the highest galvanic numbers or nobility of the active metals, *it will not be harmed by contact with any of them.(*New information from other sources: Please take note that some facts are now becoming evident that... It will, however, cause corrosion of the other metals if in direct contact. The solution is to prevent such direct contact with the use of separating materials, such as specific paints or gaskets.
It is not necessary to isolate copper from lead, tin or stainless steel under most circumstances. The principal metals of concern in terms of direct contact are aluminum and zinc.

oh boy, I don't need to research about this, especially with the EK saga of last year. Stainless is not a good conductor for heat
