Is my rad corroded or just tarnished?

post #1 of 4
Thread Starter 
Hi, I built my rig in December of last year, and today while installing another graphics card I decided to tear down everything and inspect my water cooling components. The last time I changed the water was in April.

I pulled one of my rads, (both EK XTX copper) and took a look inside and it looks a bit dark, possibly corroded. I took a needle and scraped the inside a bit, but nothing flaked off.

I took all the precautions to avoid corrosion; rinsed all my parts before I built my rig with distilled water, used only copper, and used additive with my distilled water (Primochill Liquid Utopia). The water in my PC has never sat stagnant for more than two days at most, either.

Now I also pulled apart my CPU and GPU block, the insides were a bit tarnished but other than that it was clean. No rust, only a slight white residue (not plasticizer, the additive I use killed whatever was in my loop and I guess it deposited itself everywhere which I had made a thread about a while ago). I cleaned all my blocks and my bottom rad, and flushed the entire loop with fresh distilled water. After I drained that out I put in my coolant and now it's being bled.

I tried to get the best quality pics I could off of my phone, you might have to new tab it and zoom in to see clearly. So if any of you could tell me whether or not you think this is rust I would appreciate it. If this is corrosion, what could have caused it? I can't really afford to buy new rads right now, but it doesn't look bad so I can save up some money if need be.

Sorry if my explanation isn't too clear, I've been working on my rig for the past eleven hours straight and it's past midnight here now.

normal inside of a radiator. should have looked similar when brand new. you are seeing solder and normal oxidized copper surface, and it looks clean.
