water mix?

[paxoman]

what mix can i use (dont wont to go and bye wetter water)?

[TruckChase!]

Just distilled water then, unless your water is gonna be at temps lower than 32 deg. f .

[Yodums]

I would recommend distilled water too since the best feature is if it gets on electronics it will not harm it.

Question to TruckChase! why won't you use distilled water with water under 32 Celius?

[AntmanMike]

Distilled water is only 90% pure, and what is still in it IS conductive or capacitive. Distilled water WILL fry boards.

Why don't you want to go buy water wetter? It only cost a few bucks and it make the heat transfer better. You can always use antifreeze, but you lose some cooling capacity. You really should add something to the water to keep bacteria and algae away.

[eh?]

i wouldn't use just water because it will corrode

[XprincoX]

what about some antifreeze into that mixture? :burn:

[ButcherUK]

You need an additive in the water to stop corrosion, especially if you have mixed Al and Cu. As for non-conduyctive water, it;s not going to happen. Even if you have completely pure water as soon as it hits your waterblock or radiator it's going to get ionised to crap and become conductive. The advantage of distilled water is that there are less minerals dissolved in it.

[TruckChase!]

Less mineral=less deposit on interior of cooling system. As far as bacteria and alge go, I clean my system out with hydrogen peroxide every 6 months or so, and I don't have any problems. I do, however, use a little bit of water wetter to reduce surface friction. I had one cooling system's copper cpublock wear thru after almost a year of use. That sucked. Tsunami: I meant 32 Fahrenheit... in the case that you would be using an external water chiller or something similar.

[Serrebert]

Well i dunno anything about water-cooling to be honest.

Hmm, i used to wurk on one summer as a firewurker's assistant (student at the time) for a big company where i live. I dont remember the name of the stuff, but we used to add an additive into the water based extincters for non-corrosion. It was like Kool-Aid, little toxic white cristal power. It should last long enought (one year before refill) since we used direct water from the city line and none of them ever rust nor got calcium or whatever depot in it (they were made of aluminium). Gonna check if i can get the name of that thing.

Ive got my rig on the house low pressure system with straight copper blox no additives and use the loft tank as my resovoir and pump water round about 20feet of piping I dont see how your copper block can erode...
"I had one cooling system's copper cpublock wear thru after almost a year of use"

what a joke unless the block was real shoddy, ... anyway im my system i dont suffer from any noticble corrosion and i have no additives mainly as i have to shower in this water! I do get grubbins in the pipes though its not algae but rust particles out of the water that collect in the tank + a dead mouse last month in my pump inlet dont ask me how :). (sediment like) but i blow it out every 1-2 months with the mains not at full pressure .
And ive used distilled water in a small in case system before and believe me even after a few hours if it leaks you fry as the water picks up ions etc. im no proffessor or everything but ive had nearly everything go wrong lol :). water wetter is ok but i feel there is no real need to use any antifreeze products unless your at real low temps.

It was a BE Cooling copper block that I was sent for testing.. had it running 24/7 on an old box. One day i noticed it was down and upon further inspection found a hole wore right through the face! Lost the cpu, motherboard, and video card to that little incident. Nasty.

[woodenman80]

I had a Becooling block and they are put together by moomins i think whoever had applyed the brass fittings to the block obviously did not appreciate quality ptfe taping and my joint leaked a minute unotible quantity for about a week finally geforce goes boom when power down my pc due to no heat = no evaporation :(..

So why not remove all the metal in the system?

Seriously..."Direct die" cool a peltier, nylon hose barbs, plastic showerhead in the bong, the pump is already all plastic. The nylon barbs work well enough, I've used them. Just try to erode the ceramic substrate on a pelt. It won't even lap, I tried that too, and it's waterproof.

You should still use distilled water, but why not?

[ButcherUK]

You might stress fracture the pelt ceramic though. Lot of heating / cooling cycles in a damp evironment is not good for things. Also if you use epoxy to seal the plastic cap to the pelt then you'll probably get different thermal exansion and this can rip pelts apart.
It could work... but I'd rather just use metal :)
