I am interested in learning more about the fundamentals of liquid cooling. Is anyone aware of a good article or reference that would be useful in this respect? Thanks!

Hi jpforensic,

Take a look at this article. A good place to start.

Thanks Frank - that is a great article for the fundamentals! As a follow up to this article, do you know of anything with a little more detail? More specifically, how a liquid cooling system actually cools the components?

Hi jpforensic,

If you do a Google search for: "how computer liquid cooling system work" and you will get a bunch of information.

Here is the basic operation.

You have 4 basic components:

1. A Reservoir that holds the liquid coolant.

2. A water pump that circulates the coolant.

3. A water block/jacket that absorbs the heat from the devise you want to cool.

4. The radiator with fans that dissipates the heat from the coolant.

So the pump circulates the coolant through the system in a loop back to the reservoir. This is basically what happens.

1. Coolant is circulated through the water block and the coolant absorbs the heat collected by the water block from a devise.

2. The heated coolant is pumped thru the Radiator and is cooled by the air blown thru the radiator.

3. The cooled coolant is returned to the reservoir and the cycle is repeated.

This process is possible as heat is always transferred from a warm element to a cooler element. Because the water block is cooler than the devise it is attached to, the heat is absorbed by the water block from the devise. The coolant entering the water block is cooler than the water block and the heat is absorbed by the coolant. When the heated coolant flows thru the radiator, the air blown thru the radiator is cooler than the heated coolant. So the heat in the coolant, in the radiator, is absorbed by the cooler air and dissipates into the room. The coolant exiting the radiator is now cooled and ready for more work.

You can see that if a room is too hot then a liquid or air system won't work efficiently. The best location for radiators is a place that the air blown thru the radiator comes from out side of the computer and is not exhausted into the computer. Only a few cases such as the Aventum are designed so the cooling air is collected and exited into the room. A proper set up of fans and radiators is important for efficient cooling. That is, in my opinion.   

Frank

Perfect Frank - thanks for the detailed explanation. Ill search the net for greater details but I was mainly curious about how it was configured around the components that it cooled. (Im an analytical chemist by trade so Im always interested in the theory and hardware behind the instruments that I use - I can explain the intimate details about a quadrupole mass spectrometer but my understanding of the PC is woefully lacking.) Thanks again!

Hi jpforensic,

My bad, I didn't read that story before I posted it for you. There is some basic information you can gather but the writer doesn't know much about water cooling. He chose a poor case for a water cooled system and his work in the case was terrible. The air and water cooled system had pretty much the same performance at 1080 resolution.

Get your water cooled system from DS and you will have a much better system. DS knows liquid cooled systems and is a leader in the industry.
