Water Wetter

[Voodoo Rufus]

I just bought some Redline Water Wetter, and I would like to know what is the optimum mix for computer cooling? I'm moving from my anti freeze and distilled 50/50 to the water wetter, so how much of a temp decrease could I see? Right now I have roughly a 15C delta between ambient and cpu loaded.

[Gravity Man]

Use about 1 oz. of water wetter for every quart of distilled water. Also, I think you will get a reasonable temperature drop wth water wetter. I don't have a very good setup, and I usually run about 39-41c under load with an ambient of 23c (and I'm effing cold).

Im considering connecting the powerhead water pump from my fish tank to the tubes of the water block - no pump needed, no radiator and NO FANS, and it runs 27/7

i doubt the pump in your fishtank will be powerfull enought and will probably need adaption.

2 oz. water wetter , 19 oz. anti freeze , 107 oz. distilled water
use on green anti freeze the red stuff eats pvc

hows your temps? building a new system similar. just modded
blackice for 1/2 hose, panflo h1.haven't got pump or block yet
plan on getting ehiem 1250. split between swiftech and dangerden for the block.

Skip the antifreeze unless you're running sub-zero, it hurts performance and you don't need it if you have wwetter for corrosion control.

[Neco]

yea, anti-freeze and water wetter is not good.


most places I have read call for 2 oz for every gallon of distilled water.



I usually just put a cap and a half or so into my res and let it go..


heh.. I wonder if I got too much in there tho..

[WarriorII]

Read the Sticky at the top of the Cooling Section posted by "r0ckstarbob" :D GREAT INFO for H20 cooling.

Glad you brought this question up, I was wondering myself yesterday. (just priced & found a place that sells WW here locally for $6.95/12oz)

Good Luck.

:cool:

[Voodoo Rufus]

I've read that if you have too much water wetter it doesn't hurt performance, just gives the system a color to it

[Diggrr]

Water Wetter will add a slight pinkish tint to the water, but not too much. It won't overpower dyelight or other colorants.

Changing to anything from a 50/50 mix of antifreeze will help. That amount is good for your car, but not what's needed in a cooling setup. Use it like water wetter, an ounce per quart (10cc per litre) for a room temp system. Using a refrigerator requires a different mixture like in the watercooling sticky at the top of the cooling forum. Also keep in mind that the bottle's instructions are for a car.

The Maxi-Jet pumps are power heads from aquariums. As others are already using these successfully, I'd say go for it as long as it has threads for fittings. Watch your temps upon the first boot up though...just incase. (a must for any new system)

See ya Gents.

[ButcherUK]

Too much wwetter will hurt temps. You should use 1oz (3-4 capsful) per quart, as stated on the wwetter bottle.

[Diggrr]

Hey Butcher, it says 1oz per quart on the bottle? (don't use it anymore)
I stand corrected. I thought it said 2oz. per quart.

I also hadn't looked to see exactly what an ounce was compared to cc's. I do use 10cc per liter (antifreeze), that's 1/3 of an ounce as I just measured using a syringe. It stops corrosion, doesn't change the temps at all, and don't smell like monkey poo.
(not that I have a monkey to compare to :D )

I used Water Wetter in the same concentration, and got the same results. If I added more, the temps went up a degree.
Just what I found...your mileage may vary.

I think the Maxi-jet are great pump. They are tiny compare to the Eheim, so if you don't have much space in your case, go for the Maxi. The Maxi-jet is also 1/3 cheaper then the Eheim.

Right now I have the Purple Ice, is there a difference with the Water Wetter and Purple Ice?

[res0r9lm]

If waterwetter prevents corrision. Why do you have to use antifreeze?

[Diggrr]

Use one or the other. I used up my WW in various rebuilds of the system. I like antifreeze cause I can get it anywhere. WaterWetter can't be found here for some reason. I've tried a dozen parts stores, and the big stores are no help at all. It's also $7.00 per gallon. Do the math (add shipping too).

[res0r9lm]

I payed 5 buxs for bottle at auto parts store

[pHaestus]

Rockhammer has tested out different amounts of WW for us already:

He found that the recommended dose of 1 oz/quart was optimum

You don't need to use antifreeze in a computer. You should only use antifreeze if the water will encounter temperatures below freezing.

[ButcherUK]

diggrr, it's 28.4 cc to 1 oz, so rec dose of water wetter is about 30cc/litre.

i run that setup

ehiem 1048 158GPH about 10 feet tubing and a leufken waterblock...

21Case temps and 31C load

[eh?]

ahh starcraft is a good game :D

[f155mph]

Hey you can soak feet too while on the computer!:D

Anyway does WW really smell that bad? I use it in my car before and I didn't notice it. I didn't notice a temp change either. So does that stuff work? I got Purple Ice right now and I am thinking of adding Antifreeze. The guy at Jegs told me you really can't trust that stuff for corrosion. Lastly does WW foam up? The Purple Ice made my res look like it was filled with soapy water.

[pHaestus]

it will foam in lines if air is present. Water wetter is basically a surfactant (a kind of soap) at a high pH.

[Gravity Man]

I have never seen Water Wetter foam. I use it in my computer, and my dad uses it in his motorcycles. I have never seen any foam in my cooling system or in my dad's bikes.

I also took the time to perform a highly scientific test in which I took a jug of my mixture of distilled water and water wetter, and shook it up really well. I performed the test multiple times, and I found that I had to shake the mixture quite vigorously in order for anything resembling foam to form. The "foam" that did form dispersed within a few seconds of when the agitation stopped.

As for WW foaming up at high pH levels, that may very well be, but then most people don't put sodium hydroxide in their cooling systems. Under normal use you should be fine.

[ButcherUK]

Water Wetter does fine for corrosion, the guy at Jegs wss probably trying to sell you some antifreeze

[pHaestus]

No I meant that ww itself is at a relatively high pH. I think it mentions that it is basic on the label. That is part of what makes it have that oily feel (along with the surfactant). Once you dilute that 1:30 in water though I doubt it is too alkaline.

[ButcherUK]

Yup "Contains alkaline materials" on the label, I'd check the ph if I had anything to do so with.

[BillA]

Gravity Man

as soon as you start shaking your arms at the rotational speed of the pump impeller . . . .
your "highly scientific test" will show you what others are talking about

I'm guessing it's the ph then that causes WW mixtures to slowly eat away at the exposed ID of clear vinyl tubing
(making it translucent/opaque)

so I went to silicone except for the short hook-up pieces to the item being tested - to be able to ck for foaming
(easier than taking the top off the bath)

be cool

[ButcherUK]

Water wetter eats pvc? eek, good thing I'm going to silicone.
Also does that mean it can eat impellors or their housing in pumps? Or are they some other type of plastic?

[BillA]

- putting on polymers engn hat . .

I suspect it's the (un-crosslinked) monomer used in the vinyl as a plasticizer that's being dissolved

clear vinyl tubing is FAR less chemically resistant than pvc

be cool

EDIT: spelling

[ButcherUK]

Ahh ok, not so worried that my eheim is about to crack in half now ;)
