I was very careful about that. I know EC6 is compatible with anything because I've been mixing metals in my other loops for years. So I was very cautious about Mayhem, given their track record for blaming everything they can.
However, this particular one seems pretty much the same thing as EC6, being based on some sort of PG (the stuff I vape all day lol).
The copper option cost nearly half what I paid for the card tbh. I mean, at least they are honest. I bought this Bitspower block lately for my other TR rig...
Yeah, ain't never seen no copper look like that before..... This is what X1 states..

So yeah, I reckon it's some kind of PG mixture. Same read out as EC6, and the only issue I have had with that is that after two years you get like a "fatty" deposit ring in the res. Which appears to be it separating (hence the 3 year shelf life, EC6 only claims two).
The bottom line? there is no other option whatsoever. This card does not have a block made by anywhere or any one else.
