Ok You have all peaked my intrest in water cooling.

Now im not one to do things small.

I want to keep most of the build of the system in house. I know the water blocks will have to be purchaced. One for the processor and 2 for the video cards (SLI).

My thoughts and a request for some basic information.

My plan is to take 2 aluminum motorcycle radiators attach them back to back. close off the fill neck on one and weld the tanks to geather kinda making a 4 core raidator.

For the pump i want to use an Eheim Universal "Hobby" Pump the modle 1262 a 900 gph pump.

So if you visualize it will be a high volume hight pressure rigid system.

Now the questions.

1. On most water blocks what is the max PSI that they can handle?

2. Since The actual amount of heat generated will not really be that high can I use clear acrillic tubing about 1 inch with a wall thichness of 1/16?

3. Since I will be using a 4 core radiator will a additional holding tank be needed?

Ok blast away!

If you are going for a high flow high pressue system I would not advise using acryllic tubing because it has a tendency to dry rot over time. Im guessing by a holding tank you mean reservoir. It is not critical but it will help you keep a good eye on the water level of your system at a glance not to mention give you a place to add any additives you may need to add with little trouble. Now the res can be as small or as big as you wish to make it. I dont see any problems with water blocks being able to hold the pressure that pump will produce with a total flow restriction because its a centrifugal pump so it will stop pumping is pressure gets to great the pump will just dead stop. In reality the weakest piece of a water block is the rubber o-rings that seal it and those even ones that small can hold a very good amount of pressure. You should see any problems arise when you leak test it if there is anything wrong with the system.

that pump is overkill! lol over 2x the gph of the D5

dont get this pump i had a 600gph pump not good too much preasure you tubes will pop and if there is a little leak you computer will get filled up in seconds

Agreed, you'll create way too much pressure with that kind of pump, unless it is adjustable. Most blocks are rated for 85psi

I would just get a D5/MCP655 pump

Instead of clear plexy how about clear PVC?

http://www.clearpvcpipe.com/

it says it corosion resistsant and dont they make coolant that is non corosive? I will have to use that since the 4 core radiator will be made of aluminum.


As for the pump i could bring it down to a smaller pump (i guess bigger is not always better.) Psst dont tell my wife . lol

but from a design stand point the project is do able?

anything is do able. knock down the pump a little, you can put the extra cash into something that will actually help the system, like thermal pastes or in my case liquid metal.

Just do some researching on which blocks to get. I'm going all swiftech mainly because I've heard people getting good results from it and the way their blocks are designed

I just like these kind of numbers for the MCW60 GPU block

you probably will not want to go with that thin of a wall tubing. the pump will cavitate the tube (suck it closed). so a thicker walled tubing will be needed.
And at 1" what kind of barb are you going to use to connect that to a water block?
As for the rad idea, its great. But it will probably be more efficient at heat removal to run them in series, not back to back. each with their own air supply.

Motorcycle radiators!!! get real.

1. That pump will only put out 5psi (at max head) and will add twice as much heat to your system as your CPU will.
2. Tygon R-3603 1/2" ID
3. T-line.

You have alotta learning to do...for example That Eheim pump, rated at 900gph wii probably only push 60gph through your loop the the rest of the emergy will be disipated as heat, most of which will go into your loop.
a 900gph pump will only pump 900gph with NO pressure. You have to look at pump PQ curves (and fan PQ for that matter as well)
