Watercooling Liquid

Wayne~ · 7 Nov 2008 at 15:45

Just wanted to ask guys (and I know it will have probably been asked before)
but I'm getting my new system tomorrow and it comes with watercooling for the CPU but at the moment needs filling.

Now I need some suitable substance to put in it and I want to do it tomorrow so need to buy it from a shop, where can I get what I need?

Thanks, Wayne

i use feser ultra pure water

try and avoid dyes and colourants

Feser always, I've spilt it in my psu before and did no dmg

Its awsome stuff and in so many colours

Feser here, lovely UV green.

To buy from a shop local? Only thing is de-ionised water from the local petrol station etc. Then later next week order Petra'sTech "PT_Nuke" Concentrated Biocide and add it in then your set for ages.

Ahhh thanks guys, so the deionised water it is- if I had time to wait for the feser I would hehe

Water gives the best temps(lower)

Well the tubes are black anyhow so I'm not fussed with colour

Bradley8988 · 7 Nov 2008 at 17:45

As long as it dont leak and you dont want UV then Water is the way forward. just leaktest and all will be coo.

If the tubes are black then you don't even need the PTNuke as algae won't grow if there is no light.

mmmm not sure that either true or provable or any significant difference.

quite a sweeping statement.

It's true. The best non-superconductive fluid is pure water. The purer, the better.

Your right, but I find that difference is negligible, maybe a 1 deg C in it.

I recommend Feser one also. Had problems with Zalman stuff... read here http://forums.overclockers.co.uk/showthread.php?p=12857380#post12857380

I'm not especially doubting the fact it is but is the difference even recordable?

Well, if it really is better, it should be measurable. The issue on recording temperatures is that most of us are lazy and rely on Coretemp or GPUz to tell us the temperature values. If you have an in-loop thermometer I would say you would be able to measure the difference. As to whether it's 1C, 2C or 10C, I couldn't say, but I only run Qualitex Icewater which is double distilled and micropore filtered for purity and sterility. It exceeds all EU standards for water purity, even better than the Feser stuff. The downside is it's almost impossible to get hold of unless you have a laboratory or you're prepared to take 1000l IBC quantities.

so just to be clear.. utterly, utterly pointless?

Algae WILL develop in black tubing if a clear res is used.

Distilled/Dionised water amount to pretty much the same thing - pure water with different purification methods used. Both are commonly used in watercooling due to their conductive (lack of) properties.

The more you add to water (dye/biocide), the less pure it becomes and hence the lower cooling properties it will have. However, this barely effects temps (<1c in most cases) so I wouldn't lose sleep over adding a couple of drops of PT_nuke/Iodine.

The trouble with premixed dyes is that all dyes start off life as powder and will, eventually, return to that state clogging up your rads and pin fin/impingement blocks without regular maintenance.

Everyone is saying different things in this thread ;o

The specific heat capacity of water is very high, higher than most other liquids you'd even want to think about. Any impurity will lower its SHC, the mixture will have a final SHC in direct proportion to the amounts (by volume) of the two components. Take a look at this liquid chart, Ammonia is slightly better, wouldn't recommend it lol.
