A question, how water cooled PC's work? Is there a little tank that you refill with normal water that is pumped through all the pipes/tubes? Does it eject/expel too many heat?
Generaly speaking Water Cooled PC's work the same like Air Cooled PC's. The difference is the location where the heat exchange happens.
In an Air Cooled System this happens near the location of the Heat Source ( the CPU, the GPU, the PCH, etc... ) while in a Water Cooled System this can happen somewhere else inside the Case or even outside as the heat is first moved to a
more favorable Location for heat Exchange.
Now what is a
more favorable location?
a) Somewhere colder thus improoving cooling performance by temperature difference
b) Somewhere more spacious allowing for better and/or less noisy cooling performance by using a larger Cooler or Radiator
c) A combination of the two above
While it is possible to run a Water Cooled System with regular tap water it is not recommended because of impurities that can cause algae growth. While you can use
shitload of Additives to prevent this it's just more favorable to use distilled water or something of similiar purity and then
less Additives.
You can technically make a system without a Reservoir but it'll make it pretty difficult to bleed all the air out of the System which is the main source of noise in a water cooled System if not propperly done - Closed Systems like the
Corsair Hydro Series for an example are simple enough to bleed at the factory for this not to be an issue.
With Water Cooling there is no too much heat expel - You can not go below ambient temperature so the risk of condensation is not possible. It's just just easier to get NEAR ambient temperature because of larger heatsinks.
Liquid cooling is more efficient than air, and quieter. But it's more complex and could leak.
Depends... IMHO using a 120mm water cooled System is neither more efficient nor quieter...
Only the location of heat exchange differs which kind of defeats the purpose of such a System.
But that's just MY opinion.
