Watercooling green/blue stuff all over - Page 2

post #11 of 17
Thread Starter 
Yea, the tubes looked green/blueish from the outside. But the stuff I found inside (and the water) was very clear blue.

So it's either copper sulfate or plasticizer I guess ?

As I wrote today, the blue is all gone now after I used the cleaning additive (http://www.coolerkit.dk/shop/cleaning-agent-sysclean-2610p.html)
Now it's only light cloudy water I'm flushing out. It's made the new tubes a bit cloudy though, but can still see through them..

The anti corrosion/algae additive I used originally is not Feser. It's this: http://www.coolerkit.dk/shop/antikorrosions--og-algevaeske-2574p.html

What bothers me a bit, is the damaged fins inside the blocks frown.gif Hope it doesn't get worse as I start doing proper maintenance every 6. month

By any chance did your reservoir do a lot of water churning where you could actually hear water splashing around? I'm wondering if your coolant didn't turn into an acid.

Hmmm.. No splashing going on in the res, no.

As far as the block goes , it looks and sounds like impingement corrosion .

DaaQ, can't quite find a good explanation of what impingement corrosion is?
Is it something to do with the very high pressure/flow right on that spot?

Could the pump be too powerful for my system? (Maybe take the top off?) It's surely isn't underpowered... theres quite a constant "wave" in the res, but no splashing..

I've also installed some temp sensors after rebuilding. One right before the rad. and one right after. I'm only seeing a max of 0.5 degrees difference between the readings (water was around 30 degrees C, but not more than 15 minutes of stresstesting) Is this normal?

Here you go, I don't have time running late for work.
