I got two questions....
I'm using a thermaltake big water SE kit on a P3 1ghz test rig...
I have removed the fan off the rad as it doesn't get that warm...

Question 1)
Anyone know the inside and out side diameter of the pipes coz I want to put the rad outside for winter....

Question 2)
how much diference would it make if I use meths for the cooling liquid....
I'm thinking of having it 'boil' in the water block and then condence in the rad... (starts whistling) has anyone tried it?
 
i think the tubing is 8.4mm id or summit im not sure though but i dnt think meths is a good idea atall
 
Isn't meths flamable???? I personally would not use it until I have understood the risks associated with it. Also meths vapour I would imagine be highly flamable so if your system leaked while running you could blow up your house big time when you turn your lights on.

I would try a CFC (refridgerant) replacement. Something that is environmentally friendly and relatively non toxic.

Seen people using low viscosity oils.

what do you mean by meths?

methylated spirit e.g. paint stripper or IMS99 (industrial methylated spirit) which is a mix of ethanol and methanol (or ethanol and ethylacetate in the case of TSDA)?

Any ethanol base is going to be dodgy as it is flammable and slightly corrosive, I don't think it would do your pump much good.

The pump is likely to build up a static charge in a solvent also which may discharge in the block causing a source of ignition.

Ethanol boils at arount 78 degrees C. If that's the temp in your waterblock, you have problems.
 
hmmz, all i can say is 'can someone smell burning?' ;)

Don't think it's a good idea to use meths mate...

its a thermaltake bigwater, not even jesus could make that thing cool a cpu, never mind meths :rolleyes:

it's bigwater SE.... and it's quite happy on my test server.....

ok, anyone know of a liquid that has a boiling point of around 30 deg C ?

liquids that have a boiling point around that range are generally petroleum derived solvents.
They are flammable!
Although they boil at ~30 degrees, their flash points are much lower

The flash point is the lowest temperature at which a solvent gives off enough vapor to start burning when a heat source is present. Each solvent has a different flash point; low flash points are more dangerous.

Dichloromethane boiling point 39.8 flash point -97 degrees
Diethyl Ether boiling point 34.6 flash point -40 degrees
Ethyl Ether 34.6 boiling point 34.6 flash point -45 degrees
Pentane boiling point 36.1 flash point -49 degrees

Your pump will be made for water and as such may generate static electricity in a solvent. This static may be discharged when it hits something conductive such as a waterblock. There will be a small spark and it will burst into flames!

solvents also aren't going to be cheap.

Just get a decent water cooling set up or a phase unit (suprising how cheap they are second hand) if you want extreme temps
 
We synthasized meths once in chemistry :p Smelt like funk, and burnt like nothing else. Wouldnt want that stuff anywhere near me, my pc, or any1 I cared about.
 
oky, in that case I'll just buy a 100 bar presure washer from argoose and use that for a pump....
 
vent the water vapour into a large 80mm tube.... down to bucket where it should have condensed.... any that doesn't, gets vented to atmosphere...

Then back around into compressor....

hmmm, might try it with air first.... 100 bar air compressor is only £60 ish from argoose....
 
while I applaud you thinking about new things can I ask why you are trying to reinvent the wheel?

The water can only cool to the ambient temperature where it is stored so why not just a good watercooling rig?

P.S. What you are suggesting is going to take a lot of deionised water and additive
