this was my first attempt at water cooling and i used tap water ( im going to assume that everyone knows what happened after that) i was wondering if there is any way to get it off, like with sand paper or anything else. i looked on the inside of my cpu and gpu blocks ( both swiftech) and there is very little corrosion, actually looks more like tarnish.
 
Go to your local hardware store and look for some sort of cleaning acid or bleach. Also, see if you can find a plumbing product used to clean copper piping.

I'm sure you already know now from your mistakes, but just a word to anyone else reading this... NEVER USE TAP WATER.

the only prob with that is you gotta make sure to get all the residue off, right?

i had some corrosion or something on my heatsink, just used sandpaper and lapped it
 
If it just looks like tarnish then it probably is. You wouldn't get much corrosion unless you had aluminum parts in there, most likely. To clean the inside of a waterblock, buy some radiator flush from an automotive store.
 
Tarnex!!!

I'm sure any hardware store has it. it works great to get rid of that nasty discoloration.

yeh but u can't lap the inside of the blocks unless you take it apart.

no reason to lap the inside, just use fine sandpaper, who cares if it is flat? wouldn't the rougher edges allow for more turbulance and equal better cooling? (im not sure, just guessing here, don't have water.... yet) as long as there weren't any loose particals to jam the pump or something......

im not planning on watercooling but what do you use for the water part?

don't quote me on this now, but i believe it is distilled water with water wetter or similar (feel free to correct me tho someone)

Hah! I quoted you!!!

Actually you are correct, that is exactly what I use. Some people will put in antifreeze(and I did my first time too), But if you are careful when putting it all together, then you should be able to run just fine on WW as your only additive. The Distilled water is the important part, I would never suggest tap water.

yeah, and i quoted you..... what i meant by the "don't quote me on this" thing was not to have him go spread wrong info all over the forum, then ask why his wc screwed up on him

but i got a question for those on water, why use antifreeze? does it do anything even tho the water doesn't get close to freezing? (assuming you aren't using a water chiller)

For one thing, some people are misinformed and think they need it. Other people use it because antifreeze usually has some kind of corrosion inhibitor in it.
 
Antifreeze contains lubricants and anti-corrosion additives to help keep componants from wearing out/deteriorating. It also prevents algae from growing in your system and helps reduce cavitation. It does NOT help the water transfer heat better. Water Wetter does not help transfer heat either, it prevents the water from absorbing too much oxygen and keeps bubbles out.

Supposedly Water Wetter lowers the viscosity of the water, which would allow if to flow better/cool better.
 
what about that CLR stuff that people always run infomercials about. that should take care of the corosion. then rins the stuff off and let the things dry fo a day or two
 
I new what you meant, kllrnohj, I was just being silly. Looks like somone above already answered your anti-freeze question.
 
WaterWetter does help heat transfer. But if it's enough to be noticable in a WC system is another thing.

WW is a surfactant. It reduces water's surface tension making it 'wetter', like soap does. Reduced surface tension reduces the viscosity. Lower viscosity shrinks the boundary layer between the water and the walls of the fluid system. Boundary layers are formed when the water in the center is moving faster than the water touching the tubes/walls of the system, reducing heat transfer. Turbulence is used by various water blocks to reduce the boundary layer. A good example is LRWB Cascade, which uses jet impingement to reduce the layer as much as possible.

Using WW helps a bit but who knows how much. It was designed to use in cars which run much hotter than a pc. Similar physics but with the added effect of reducing localized boiling by removing vapor pockets which insulate the hot spots and prevent the coolant from doing it's job.
