So, I have a Enermax Liqtech TR4 2. The Threadripper AIO known for corrosion issues. It is unused, and I have drained it of the fluids today. Taking the pump and cold plate apart, it shows no gunk or corrosion thankfully.
My question is about reducing corrosion. Ideally one would run only similar metals in a cooling loop, however with this AIO it is not possible. Even If I were to replace the radiator with an all copper radiator, the housing on the pump is aluminum. It appears to be anodized, but it is still aluminum.
With the copper cold plate and the aluminum pump housing, all other things being equal, would replacing the radiator with an all copper radiator reduce or increase the corrosion potential? I do think that it is likely that the corrosion others have seen is probably mostly from the radiator, but I don’t want to change it, if it will increase the corrosion rate of aluminum in the pump housing because the ratio of copper has increased. However, I will gladly and willingly change it if it will not likely increase corrosion and gunking up of the cold plate.
Of course I will be replacing the fluid with a more corrosion inhibiting formulation, and not the original that apparently caused problems.
