Corsair 750D Build

virus86 · May 1, 2015

This will be my first custom water cooling attempt. Ive been using AIO watercoolers for the past 4 builds just for the CPU and now I want to watercool my GPUs. Id like to push it to the limit instead of upgrading. I plan to start this project in a month or so. My current setup is:

Corsair 750D
- AF140L (2 front intake and 1 read exhaust)
- AF120 Performance (2 bottom intake)
ASUS X79 Sabertooth (optional 40mm fan installed)
Intel i7-3930k
- OCed to 4.8GHz @ 1.36V
- Cooled by a Switech H320 and 3x Corsair SP120 Performance (intake and push)
EVGA GTX Titan SC SLI with backplates
Corsair AX1200 PSU
Sunbeam RHK-EX-BA fan controller

Id like to keep the parts Swiftech, but the parts Im looking to get are all sold out. I also wanted to get a chipset and mosfet cooling block, but the nice ones are no longer made. The chipset block has the ports right above the top PCI express slot. Here is my idea thus far:

Keep the CPU on a separate loop and dont touch the H320
GPUs on its own loop
Corsair 750D Front panel high airflow
Corsair bottom rad mounting kit
Switech KOMODO-NV-LE for my Titans (parallel flow)
Switech MCR220-XP mounted on the bottom, cooled by Corsair SP120 Performance, intake, pull
Switech MCR220-DRIVE-R3 mounted on the front, cooled by Corsair SP120 Performance, intake, push
Switech HydrX PM 2 Coolant (same as the H320)
Clear tubing

I dont know which fitting to use yet. Ill probably get one thats the easiest to use and looks great. Some questions I have right now:

Should I separate the loops?
If I combine the loop, is the H320 pump strong enough (add two 240mm rads and two GPU blocks. My thought is no)
Should I just ditch Swiftech since they are out of stock on a lot of stuff?
Should I incorporate a drain port? (I probably will if I combine loops)

Thanks!
