CPU/GPU metal compatibility question

post #1 of 6
Thread Starter 
Hello resident experts on the watercooling subject,

I am a complete newb when it comes to watercooling, and figured I'd give it a shot. I have 2 5970s so thought I might as well WC them to start with, instead of upgrading my GPU. I was struggling to find blocks for them, but stumbled upon this:

http://shop.watercool.de/epages/WatercooleK.sf/sec98425de96a/?ObjectPath=/Shops/WatercooleK/Products/150025002

I was also going to use a Swiftech H220. The GPU block is a copper/stainless steel combo, H220 being copper.

My question is: is mixing metals ok in this instance? Stainless steel has the property of not corroding, but I just wanted to be sure oxidation/reduction wouldn't be an issue.


Many thanks for any help on this matter.

You'll be fine. The stainless steel is more than likely just used on the outside of the block with the internals being copper

Coolant will only touch copper on those blocks.

Thanks, I figured I'd be fine. I'm tempted to go with an XSPC kit, instead of the H220. More stuff involved, I guess, but I can use my other PC in the meantime of stuff annoys me.

Looks like the top of that GPU block is SS, so the water will be in contact with it. SS and copper are fine together anyway - open up pretty much any block with a jet plate and you will find the plate is made of SS - the EK Supreme HF is a good example of this:

Oh, and as an aside, SS isn't immune from corrosion. Pitting and crevice corrosion still happen, and if you use it with things other than water then it can corrode pretty quickly. It is more resistant to corrosion than carbon steel, for example.
