Yeah, but he's not trying to heat water, he's trying to cool the water block.
No.
If the water could absorb the heat instantly, you could put a pan of water on the stove, and as soon as you turned on the heat, the water would boil.

If the water enters the water block at 50F and leaves at 55F, thats good. If the water enters at 50F and leaves at 60F, that's better.
Hopefully the water from the radiator goes to the CPU first. Otherwise the CPU would be getting warm water from the other water blocks.
Dd, have you considered branching the source into parallel circuits.
You could build your own out of tin foil.
I was joking.
The reason you monitor the water temperature into and out of the water block is to see how well the water block is working. The higher the temperature difference between the incoming water and the outgoing water the more heat you are removing from the water block.That would be the flaw in the logic right there. I don't care about the temperature of the water, just the waterblock. Try to explain your position while only describing the temperature of the waterblock, not the water.
The bigger the differential, the more heat gets transferred. Therefore I want the biggest differential all the time. The biggest differential is when the water first hits the waterblock from the radiator. The longer the water sits at the waterblock, the smaller the differential, the warmer the waterblock will be.

It just takes a lot of energy to heat water to a measurable degree. Unless its tired...then its nearly impossible to get water excited.
I often hear that, but nobody seems to have any evidence. Got a link? I'm not saying it isn't true, but like so many other oft repeated watercooling maxims, there is a good possibility that this one might also be false.Ever considered mixing 50% anti-freeze 50% water? Anti-freeze is MUCH better at absorbing heat then water.
What do all of these numbers mean in a liquid cooling system?
The above thermal conductivity shows why copper is the preferred cold plate material for cooling systems. It is extremely close to silver in performance, but only 1/6 the cost. Like most metals however, copper doesn't hold heat for very long-- it needs to be absorbed by something else.
The specific heat capacities show water to be the best liquid for holding heat. Practically, it is also the best for transferring it.
This would indicate the ideal configuration is to use copper to transfer heat from the processor, and to use water to absorb and move away the heat. Although there are many other factors involved, here you have the basic foundation of a liquid cooling system.
Just car experience. With anti-freeze the temperature on my water-goes up to 50%, very quickly.
Likewise, as soon as the load is less, it drops to 20%, or less, quickly.
Pure water, the temperature will rarely go past 40%, but, once it gets up there, it stays there, longer....
A trickle of water began running down the back of the card and into the PCIe slot.
My take is that the observed behavior indicates that the antifreeze/water mix is less efficient at cooling than 100% water
Stupid question time? Why choose water cooling, over either Peltier coolers or Phase change cooling techniques?
Distilled water, right?
Nope, sediment-heavy tap water with some dye in it :cyclopsani:
Don't you go getting crazy now. :smack:

Peltier coolers are slient and offer very good cooling properties at the expense of electricity usage.
And Phase change cooling will get temps on the CPU down to -15C with top end equipment even when overclocking and the component(s) are under extreme load.
And the upshot, is with both you don't have to worry about burst pipes dousing water over everything.
FYI: Peltier Effect and coolers see: http://en.wikipedia.org/wiki/Thermoelectric_effect and http://en.wikipedia.org/wiki/Peltier_cooler.
Since you don't use cases, just mount the motherboard as the bottom component in a chimney, with the board upside down. Any condensation can go into a 'drip bucket'.I had considered using a peltier in combination with my CPU waterblock, but I can always do that later if I need it. The condensation is a scary thing as well.
Peltiers are WAY cooler then water cooling;0
