help- this water cooling mix any good?

[jester01]

planning on water cooling my rig but i really don't know one thing
about it, was reading on the forums about mixtures and came up with this -
89% distilled water, 7% antifreeze (i am using copper and aluminum) 1% biocide and 3% alcohol.

is this any good or will something go horribly wrong :(

Distilled water and two drops of PTNuke
That is all you need
You don't need antifreeze unless your living in sub zero temps.

Dap, he's using mixed metals. He needs anti-corrosion stuff. I would only use Pensosin G11 antifreeze, good stuff, used by WCs a lot. I'm not sure on the recommended ratio.

Get Petras PT-Nuke, 1-2 drops NO MORE.

Alcohol, no wayyyy in a loop. If there is any acrylic it will degrade it and it will crack.

You should be fine, mind posting your rig etc in your sig so we can be sure?

VW anti freeze as well as dexcool by gm is great and designed for mixed metals.

ive been using %10 antifreeze since watercooling has been used and tapwater and my loops have been clean as a whistle even when ive had mixed metals.

someone said never use tapwater use only distilled water. if your using antifreeze tap is fine with no ill effects. if i used 1-2 drops ptnuke then i would.

test done have showed very little temp changes if any depending on the water used. with that said too pure of water is bad [RO water] distilled in the sweet spot. im not worried about a 1/10 of a degree at most to buy distilled.

when using mixed metals, no. otherwise thats the way to go.

and of course +1.

it's not a matter of performance from tap vs distilled its the extra crap you put in your loop when you use tap water.


i would go with 10-15% anti freeze and distilled water with 2 drops of pt nuke.

[outhouse]

and what extra stuff would cause any problem in a PC loop ?? and what problems?

5 years ago or so we did a water temp test here at this site with every water and mix imaginable and there were slight temp differences in the water mix used.

[Spawn-Inc]

as i said its not a issue with temps its all the mineral's and impurities that get left behind as the water evap's off. now if you do water changed every 6 months its not as bad but when distilled is only a buck a gallon, why not use it?

[outhouse]

why not use it?

cause since the begining of water cooling ive been using tap water plus antifreeze and change water out every 2 years or so when your O-rings need replacing and my loop is as clean and pretty as it was when its new.

loops dont evap enough to leave any harmfull levels of minerals and impurities now if i used PTnuke i probably would use distilled.

its not worth argueing about, im just trying to make a point here that tap water is not as bad as people think.

dont make me go get pond water and run it for 2-3 years lol

[jester01]

so 10% anti freeze, 1-2 drops ptnuke, and the rest distilled water?? since im using mixed metals. really appreciate it. here's my rig-


AMD Phenom II X4 940 Deneb 3.0GHz
Foxconn A7DA-S AM2+/AM2 AMD 790GX
SAPPHIRE 100259-1GL Radeon HD 4870 1GB 256-bit GDDR5
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V
WD VelociRaptor 150GB 10000 RPM SATA 3.0Gb/s
Western Digital Caviar Black WD6401AALS 640GB
Antec Three Hundred Black Steel ATX Mid Tower
SAMSUNG 22X DVD Burner Black
1 22" Asus monitor

i really wanna push that 940 to at least 4.0ghz, stable of course
any recommendations or tips would be nic

you dont need ptnuke if you use antifreeze

Antifreeze doesn't prevent algae growth.

all have to argue that one lol ive never had so much as a hint of algea in any loop and ive ran clear tubing the whole time.

i just went and read the other post where they say that antifreeze has nothing to do with getting rid of algea even at %10 and i will still have to disagree.

there are to many brands of antifreeze each with different compounds beside methanol and Ethylene glycol. some have Propylene glycol based solutions. most all antifreeze has the same base with different corrosion inhibitors added to make them different plus some different colored dye.

all i know is im not guessing by reading a few post here. im doing it lol. ive ran all different amounts and the only time my loop got nasty looking was once when i ran almost straight water. running 5%-%20 and ive played with it and different brands and my loop has been spotless.

its cheap enough go ahead and add ptnuke but ive never needed 1 drop

Antifreeze has no biocide. Why? Antifreeze in a car is above boiling or can be below freezing. No need.

I beg to differ, no growth in one loop doesn't mean it dosn't happen inother loops.

[outhouse]

some folks do put algea inhibitors in and allthough they dont put in biocide theres enough toxins to outrite stop growth at certain antifreeze levels.

antifreeze also depletes oxygen levels.

i think the arguement should not be how much algea growth is going on with antifreeze because algea isnt happening i would say only bacteria.

anaerobic bacteria is the probabal suspect

reality is that a high percentage of people use antifreeze in there loops and only a very very small handfull at the most have reported junk in there loop while running antifreeze.

those that say they run %10 and having problems are probably running 50/50 antifreeze at there %10 resulting in a true %5 mix.

i dont mean to buck a trend but i dont see how i could have no issue with a true %10 mix with clear tubing that sits 6" from a window for 6 years with 0 issues [and no side panel] [ive used so far dexcool by GM and the blue VW factory coolant as well as standard green stuff but very little green antifreeze and only for a short time]

[Conumdrum]

Outhouse, I agree. There is proof on both sides of what is required. It comes down you 'if it works for you'. It's a individual hobby and I'm not gonna worry about it either way.

[Spawn-Inc]

i was looking at extreme and there is aperson who used both antifreeze and a pet store biocide and still got growth, not sure how much of each. i will post the thread once the site goes back up.
