Corsair 900D Water Cooling Questions

post #1 of 6
Thread Starter 
Hi all,

I am very interested in water cooling my new rig. I have never had a custom water cooled machine before let alone built one so I would like some suggestions for my current hardware setup.

Currently I am running the following in a Corsair C70 :

Intel 3970X @ 4.0 GHz
Corsair H100i CPU Cooler
ASUS Rampage IV Extreme
Corsair Vengeance Pro 32GB @ 2400MHz RAM
Sandisk Extreme 480GB RAID 0
EVGA GTX Titan Superclocked SLI
ASUS Xonar Phoebus Sound Card
Corsair AX1200i PSU

I am a big fan or Corsair products so naturally the Obsidian 900D is very appealing for a custom water cooled system.

I would like to water cool the following :

CPU
Motherboard
2 X GPU, possibly a 3rd GPU

I am thinking about putting a XSPC RX480 in the top of the case and another RX480 on it's side at the bottom of the case. If I need to, I could also put a RX360 at the front of the case. WIll I need multiple pumps and reservoirs to drive the water through all of the above rads? I personally like the idea of using 5.25inch bay / res combo from XSPC instead of the cylindrical res inside the case. Also, do people recommend running separate loops for CPU / Chipset and GPUs? I would also like to run all of the fans off the motherboard headers instead of a stand alone fan controller unless people tell me otherwise? Other then rads, blocks, fittings and pump / res what else do I need to order?

Thanks in advance,
Alain

PS Im sure I will think of more questions to ask!

should be plenty of rad for your needs with the 2 RX480s but if u have the money and can fit it in your case then get a rx360 too!

tri sli titans should be cool.

if u want a single loop get a dual d5 pump top kit like this: http://www.ekwb.com/shop/pumps-and-accessories/pump-tops/d5-series/ek-d5-dual-top-g1-4-csq-black-acetal.html

otherwise for dual ull need 2 of everything, tops, res, pump etc.

What kind of budget are you aiming for?

If you go single loop, you'll only need one reservoir. You'll need two reservoirs if you go for a dual loop setup.

Two 480's would be more than adequate for a CPU+mobo and two Titans. It would still get decent temps even with a third Titan.

You'll also need to order some tubing and a biocide. Take a look in your case and see if any angled fittings would help. They'll help keep your tubing runs shorter and make the build look cleaner.

I would like to use something like this for a pump / res combo :

http://www.xs-pc.com/reservoirs/twin-d5-dual-bay-reservoir

Is that going to hold enough coolant and pumping power If I end up using 2 X 480mm and 1 X 360mm? Or should I add a second 5.25 dual bay res?

Budget is $1000 - $1500 NZD. Not sure what the exchange rate is like against the US sorry.

Can anyone recommend a mid tower case that could support a reasonable amount of rad for my setup?
