Hi,

Shortly I will be ordering the components for my new dual loop 900D build.

The setup will be as follows;
3x Titan X on one loops

CPU, RAM and MB on second loop.

I am looking at the EKWB Coolstream XE rads and was planning on mounting a 480 in the base and a 480 at the top. I am not sure what kind of radiator capacity my setup will require. I am happy to add a third or even fourth radiator (two per loop). I intend on removing all the HDD cages and the 5.25" bays as I will mount my SSD somewhere hidden and I will have an M2 drive. I don't intend on having any HDD or Blu Ray drive (I will have an external for the very rare times I need to use it).

So I guess my question is;

Will 3x Titan X require more than the 480 rad and if so would a single or a double be required?

For the CPU, RAM and motherboard will the 480 be enough or again will I need more RAD capacity?

Also I am intending on not having an exhaust or inlet fan as everything will be under water, is there any reason that I should not do this?
 
cpu and ram wont even need a 480. I run my cpu and two 290x off a 360 and 120 rad

I dont know about the 3 x titan x, sorry. Dont know how much heat they through out esp overclocked.

ALso consider one res and two loops rather than two seperate loops. Thats what i did so i have two seperate loops, one for the cpu with its own pump and one for the gfx cards with its own pump and on each loop it goes through a rad.

Cant see the point in two complete seperate loops. Plus then if say the 480 is overkill for the cpu, that spare cooling can then be helped to cool the titan x down.

No to be fair i dont have my motherboard cooled but i dont expect it throughs out much heat. Last time i looked everythign was at around 40C on the motherboard :)
