Tubing ideas needed

[Dude87]

OK, Building my first rig or planning my rig for a while now. have got all the parts as follwoing:

Laing D5
120x240 Radiator
120x120 Radiator
That little tank from Swiftech
Swiftech Apogee Cpu block
Swiftech MCW60 GPA block
two MOS block from MIPS Germany.
The NB blcok is also from MIPS

Here is the case that i am using, but those pictures of arrangment are not mine. But the front radiator is mounted the same way as the pic show

Anyhow, now the problem is how the tubing should be done.

Here is my plan at the moment, all blocks are using 1/2" barbs and 3/8" Tygon tube is used throughout the loop. Those red Ts are well, Ts made out of plastic or somthing.

I have also attached the the blank layout if any of you out there have any good idea for tube arrangment, please draw it on the blank layout.

Sorry for the messy layout, First time posting here.

Do not split the flow on the MOSFET blocks. Adds more complication and tubing mess.

I have something similar here if you scroll down a few posts. I have a lot of blocks with no Tees.

I wouldn'run the d5 on everything.

I would either get an additional dtek pump or mcp350/355 and run all mosfet and nb blocks on the slower pump with the mcr120 and then the single loop being the cpu/gpu on the mcr220.

Since you have 2 rads, all you need is the pump, maybe just use a t line as a res ;)

I am alredy kind of tight on the budget, spending another 100 euro on a second pump is not really a fesable option. I am looking for the best option given the blocks and pumps that i have right now. :D

If you really want to run it on one pump I would try loop layout like this:

Split in 2 loops definitely. If you combine everything with just 1 pump, you will get below 1 GPM for sure. I have 2 loops and both is averaging 1.2 GPM (don't forget I have a Swissflow SF800 on each loop causing some pressure drop).

[Dude87]

Since i have a P5k Premium board, would the stock cooler to sufficient for the mos?

would it be a better idea to forget about water cooling the mos and stick with a "CPU-GPU-NB-D5-2 rads" solution then? Really cannot afford a 2nd pump.

[GuNNeR]

Why won't you try just one loop: cpu, gpu, rad

And buy some radiators for nb/sb/vregs. Air cooling them with slow fan should be more than enough.

[Pedalmonkey]

you might be able to pull off the single loop. just plug all that into martins flow chart and then you should have a good sense of the flow rate. just run it with the least tubing possible, and no T's, they'll kill your flow a bit.

[Xilikon]

Trust my experience, I tried 1 loop and the flowrate is not good at all... This is not just a assumption but a real measurement ;) Even the flowrate estimator will give you under 1 GPM as well.

Well, I thought of spend all that money already, kind of hard to go back :d

anyhow, here is the Excel Flow chart, came out to be 1,36 GPM, is that....OK?

[Xilikon]

Make it 12 feets. 4 feets is impossible unless you give 2-3 inches of tubing between parts.

[Pedalmonkey]

yeah, you should add some tubing, but like i said you should be good. you might have been better off with not WC the mosfets because those can be aircooled with some Enzotech ramsinks or something like that, but if you must use them i think you should still be ok. You also might have been better off with a DDC pump instead of the D5 b/c of its 3/8" nativity and its higher head properties.

[Dude87]

Ha, yeah, i am way too metric to used feet as a unit, I only have about 2.5meter of 3/8" tygon which is about 8 feet. should be enough for my entirely internal loop. With that changed, the flow rate drop to 1.3GPM sharp, thats including 2 mos cooler.

Without the mos coolers, flow goes up to 1.38GPM, not really a dramatic change aint it?

Also, two Noob quesitons:

1. WOuld it be a good idea to use purely distilled water without any anti-corrosive stuff?

2. currently i have the 120 rad behind a fan that pulls air into the case at the front and the 240 rad at the rare with two fans pulling air out of the case. So both rads are inside the case, is this a bad idea?

[Pedalmonkey]

i would run pure distiled with a bit of biocide w/out any anti-corosive only if you have an all copper loop.

The rads arent a bad idea, just you want to try to have all the air going thru the rad's to be cool air although u want to have an exauhst fan out of the case too.

[Snyxxx]

Agreeed.

Run pure distilled. I add five drops of Iodine (non-alcohol version).

Have both rads sucking in cool air. The overpressure will find a way to get out.

Try one loop before you spend any more. Cannot hurt. Look at all the crap I have in my loop. Just about cannot get any more waterblocks.

For a first rig, go single loop. You will be tearing it apart sooner ot later for that next new waterblock.:p:

Five drops per ??? Liter or whats the ratio?

Thanks for all the ideas, i think i will go with single loop first to see what happenes.

Do any one have any idea how the tubing should be run in a single loop option? should the pump outlet go straight into cpu block to creat max pressure or should it be "pump-rad-cpu block" to ensure the cpu block gets the coolest water?

please draw it up on the attachmeent in the beginning....

5 drops total.

Run tubing the easiest, cleanest and shortest route. The water temperature will eventually reach steady state and it will not really matter.

However, most people recommend having the CPU as the first block out of the pump. The water temperature difference between inlet and outlet of radiator is about 1°C. So it really does not matter.
