Block Idea/Theory
 

I know from research that copper is cheaper than silver but if price weren't an issue, everybody would prefer to use silver(?) What if you made a water block that was primarily copper but had silver parts included. I've included a picture of my idea. The fans are the parts made of silver. Any clues as to how well this would work? Plus how would the mixture of copper and silver parts affect oxidization/breakdown? :shrug: Thanks for your comments!

That would be correct, about silver. As for mixing them, you'll have too lookup a galvanic corrosion potential chart.

Are those motorised wheels, or are they free-spinning? Is this a waterblock?

Off-hand, the only benefit I see to the wheels is if they were spinning outrageously fast, creating turbulence (hum... maybe I'll try that next!).

Yes, it is an idea for a waterblock. The wheels aren't actually attached to the top and bottom of the block therefore it doesn't have to be a silver/copper mixture. The holes holding the posts of the wheels are just barely big enough so that the wheels won't tip when they spin from the water. I was actually meaning for just the wheels (maybe the little fin too) to be silver and everything surrounding it to be copper.

from what ive heard, silver is a bit soft...so it would need to be very thick....very expensive.....just go for diamond
