I got a
12V Laing DDC1+ Ultra 18W DDC Top/w Reservoir --> XSPC RS360 --->XSPC Delta V3 CPU Waterblock i7 ---> Black Ice GT Stealth 240 ---> EK-FC260- Plexi ---> back to Res/pump

so what hose is best

3/8" ID - 1/2" OD Hose or 1/2" ID - 3/4" OD or does it not rlly make much diff


thanks in advance
 
Hose is to match barbs - 8mm ID to 1/2ID have very little differance.
7/16 over 1/2 barbs is very popular
3/8 over 3/8 barbs with tube clips make for easier tube bends.

No need for the Black ice, or ultra - the 10w pro and quality 360 would do
But if you've already got it all - the black ice will help slow the DDC down
 
7/16" hose is excellent as it provides a very tight fit over 1/2" barbs and vitually eliminates and chance of leakage.

You don't need 2 rads for your setup. I have the CPU, GPU and NB all cooled by a single Thermochill PA120.3.
 
The DDC ultra is a powerfull pump.
So if you use it with a small loop with limited restriction it's a nightmare to bleed all the air bubbles out, unless you have a tall res (with the res top isn't)

In theory you pick your loop hardware then size the pump to acheive 1-1.5gph (gallons per hour flowrate)

I just did a quick calc using martin's flow rate estimator - your loops runs at approximatly 1.8 gph with both rads. (using a ek3850 and a rs240 as it doesn't have every thing)
Which is lower that I thought - so bleeding will take a few hours not days

but still a DDC pro would have been a better choice if buying new.

Edit: as pastymuncher said a quality triple rad is more that enought - but I guessing that prt already owns the rads / blocks and pump OR (s)he can't install a thick rad due to their case.

So the calc you done using martins rate estimator shows my loop at 1.8gph is ok or is that bad ???

i only added the second rad 240 to help cool the gpu, not that it rlly needed it as it never goes over 39 with full cover block on it.

i could remove the 240 and 360 and use say a thermo 120.3 if it is rlly better. however dont want to go to hassle if not rlly going to keep temps about the same. i spose it will have 4 less fans by removing the 240.lol
 
any thing over .8 is good, 0ver 1.4 is great, over 2 is excelent.
if you have a 120.3 go for it - if not stick with what you have.

39c load - nice - might be the 10 rad fans
 
Any specific reason for the choice of Black Ice GT Stealth 240, was limited case space a factor then? Ideally you gonna need quite high RPM fans to push air through those tightly packed fins to get the very best out of it.

Personally, i'd go for 7/16 it bends nice without compressing (like smaller tubing) and has similiar flow rates to 1/2 - the best of both worlds really.
