That's exactly what I've been thinking...especially since I recently bought Palit 580s and discovered that no aftermarket air coolers will fit (that I know of, anyway; the DVI ports are too high). Then I looked at waterblocks and the only one I saw was the EK-FC5X0 GW block. Anyone know of any others?

Off-topic. Darn Canada Post strike just a cherry on the top of all of this mess.

This is from a thread started on XtremeSystems today.

Testing shavings did not give straight copper (II) sulfate, peroxide would not give light blue, ammonia did not give dark blue, and hydrochloric acid attacked the surface. None of that should have happened.

So I did a density test. This is where it gets ****ing odd.

Copper has a density of 8.93 g/cm3. This is closer to 8 g/cm3. Whatever I have, it ain't pure copper.

At the end of my rope, I set a scraping alight. On nichrome wire, mind you.

Blue-green and some purple. It ain't copper.

Best guesses at this juncture? Phosphor copper, ex-aluminum casting. Maybe mixed with regular copper, but there's enough of an amount that you would have trouble plating it right.

Phosphor copper won't plate right. If the billet is of variable quality, you get thin plating in spots and thick where the copper is all right.

As an aside, the nickel looked great. It's actually surprising. Seems like it really was plated properly-if it were pure copper.

I do not make any conjectures as to how it came to be impure copper. I simply read the tests as I get them.
XtremeSystems Forums - View Single Post - EK Supreme HF teardown (I found a reason why!)

Very interesting. So in a way Eddy is right. Just for the wrong reasons. There has been something wrong with the blocks, just not the nickel plating.

Kayin's findings are pretty interesting. I am no expert, but it makes sense to me, and possibly why Eddy didn't duplicate the issue if he had good copper.

Need this confirmed by someone else in my books, but if these blocks are not really full copper than thats bad news indeed.

That is unusual twist in this story. Defective raw material?

If the platting was not an issue then the blocks platted by third party companies would have failed but they have not. Second it is not uncommon for vendors to use low grade copper.

If Kayin's post is accurate, I'd have to say either EK is intentionally cutting corners in the copper process to save money, or whomever he contracts for the forging is doing the same thing, but obviously not to EK's knowledge.

On another note: RRR has quite the pack mentality it seems.

EK is not the only company to use low grade copper for water-cooling blocks.
