Scratch build planing [Project rethinked. New design 18/3]

post #1 of 5
Thread Starter 
So the time has come for me to make my first scratch build computer. Have done some case mods before but nothing that huge. Anyway this will be something special if I can bring my vision to life It's all a matter of time, skills and resources
So this will take some time to get going since there will be allot of pre planing before I can actually start building stuff
This is going to be a black painted aluminium case with water-cooling with details in illuminated plexi. It's going to be a Fulltower+ sized case but it will be filled up with allot of stuff What exactly I'm not sure yet since it will probably take the summer for me to actually complete this monster So it's better I wait with hardware so the price can go down a bit.
But I was thinking something like a Core i7 with 2 580GTX or 590GTX depending on the price of the 590.

So this will be cooled with 2 two Laing DCC pumps with two EK 3x140 radiators with three Enermax fans on each maybe 6 on each but it's a clearance issue since then there will be only 4 cm between them and they will be sucking air from the floor and push it out the sides.
Is that enough room or will it cause to much turbulence and lower airflow?

Then about the water loop. Does it matter if I have one loop that everything runs on or should I go with 2 loops, one for the GPUs and one for CPU/RAM/Motherboard?
One idea I'm thinking about is that I will run 2 loops but they will have a shared water-tank and go through the same loop through the radiators but then they will be divided to 2 separate loops and will join again at the tank.
Can I do it like that or is it a bad idea? Also

Then for the airflow for the rest of the things in the computer. Since it's almost all W/C that won't be a big issue so i was thinking of a 140 mm in the back at the CPU (will mount the board CPU down and PCI-E top) and then a 170 mm in the top for exhaust (the 170 mm will also draw some air past the HDD through a airduct to give them some active cooling as well. The lower compartment with the radiators will be sealed and the PSU will take air from there.

One loop- the Rads will work together to cool components versus one Rad maxing out at heat dissipation and the other not to its full potentional. Makes it a bit easier and saves room IMO.
Two loops means two reservoirs(single res split in two) and their own entire loop for themselves.

Additional advice- do 3D renders to a point of precsision/scale. Take your time and use tape over parts to draw lines to cut or holes to drill.

Was thinking of having the rads and the reservoir in the same loop but after reservoir there will be 2 separate loops and the pumps are on separate loops. One through the GPUs and the other through CPU/MB/RAM and then they will join into one loop and go through the rads and then back to the reservoir.

Already one step ahead of you Been playing around in Sketchup for a few days now and doing some 3D modelling and doing it really thorough and going 1/10 of a mm precision Just takes so damn long time but it's starting to look really good. Using allot of layers groups and components so that I can see individual parts when I go through it

So I have done some thinking and my design have taken a completely different approach. It will be a beast more now then before. Will build it to match my aluminium bookshelf system I have over my desk. So will build it with one of the shelves as a base.
So it will be a little bit like this



The three screen set-up is just wishful thinking and will be something i will have in the future I'm even considering to mount the screens on a shelf so they hang under it or something like that
The small screen above the regular screens is a Lilliput 7" touch-screen where I will show system info and control the fans on.

This is just a very rough draft and much will change until project lift off in perhaps end of April. Need to get my uni application in order first. So any input is nice so that the planing phase is done by then

As you can see in the picture the sides will be two cooling tunnels with radiators for the W/C. Going to have 3 different loops so it will be two radiators one 3x140 and one 2x120 in the inside compartment and only one 3x140 in the outside compartment. Already have the 2x120 radiator from a old build so that's why I have that size there.
the two 3x140 loops will cool the CPU and GPU:s and the 2x120 rad will cool MB, Ram and HDD. Will be some additional airflow over the HDD as well so not only W/C on them will have room for 8 drives total that will be W/C already have 7 disks in my current build so will only get a new 2 Tb disk for the 8:th drive.

Will the 2x120 rad be enough or will it have problem keeping all that cool?

For the radiator tunnels I will not have the fans directly on the actual radiator but a bit apart and then direct the airflow to pass through the radiators. Though I wonder if I should have some extra intake on the side for the 2x120 radiator since it will be serially mounted behind the 3x140 radiator. Maybe I should use more then just 3x140 fans to get some better airflow over the radiators.

I know that you could find most of this if you just search and read up on it but with all the pre uni studies I don't have much time over for reading up on W/C as well. When the project is starting in end of April the pre studies will be over and I'll have the summer finish it before the studies at the Uni starts and then I probably won't have time to build for a while. So I'm a little bit in a time sensitive situation so any help is greatly appreciated

Picture isn't working. Will me much easier to visualize what you have in mind with it. smile.gif
