Project: Double Header 3 Step 2 - Cooling Systems

OK Folks pull up a chair and learn how DH3 came about and what changes it took along the way.

First part we are going to cover are the diagrams I made before I even started on the project for the DH3 cooling system.  My First plan was DAMN ambitions, in fact... too much so.

That was the original plan, 4 loops, 4 pumps, 4 everything...  I was riding that plan until I got the Addtronics WTX case in.  then I realized that it just wasn't possible to fit that much into such a small space and still have room for a PC. ( the WTX is NOT small for practical uses, but for 4 loops.. yes it is very small).

This wasn't the only change the system took. Before I even started thinking about doing a multi-loop system I was thinking of working on getting 2 Vapo_phase systems and running 2 of them in 1 case :)  Cost was a factor to consider, also the practicality came into play. I wanted to build a machine that ANYONE could build, by using parts from places such as Ace, Walmart, Home Depot.   Another benefit is its cheap to replace stuff then if it breaks!   a 4 Loop monster is hardly practical for most people let alone me.  But it was going to be quite cool, with an air conditioned interior of the case.  The Theory was, if you lower and dry the air before it enters the case you lower the risk of condenstation.

After much thought I redesigned DH3 many times, and the final plan that I came up with was this:

Theories and principals at work in this are these:

  1. Keep the Res. tanks high in the machine, that will auto-prime the pumps, and help with the flow of coolant. This will act as a air trap and a eliminate air from the system rapidly and automatically.
  2. Keep the runs from the radiator to the devices its cooling as short as possible. I can deal with having a lot of hot coolant runs in the machine, but the ones that go to the devices must be short and directly to the device.
  3. Keep The CPU loops separate from everything else and each other to give accurate bench marking per loop per CPU
  4. Make the system completely modular and flexible.

in Photoshop I did lots of test size'n and drawing.  I took a Pic of the radiator with a 92mm fan on it and placed it around ( I only had one radiator to play with for a while)   I was playing with this idea, but I ended up putting one upside down from the other insdead.

You will see more pic's like this when we get to the electronics portion cause I designed all the face plates in Photoshop first.

As you can tell I was very careful to do all the planning I could in a cyber interface before we cut metal or bought the wrong stuff.   This has made me a believer that you need to do complete planning and testing before committing to something. 

Since you know what the deal is now, Here is a quick pic of the entire cooling system in all its glory

Now onto a VERY detailed look at every component of the cooling system.
