Hello,

Planning on my first water cooling loop and need some help before I start buying things. I'm aiming for a loop that is as quiet as possible, so I'm willing to sacrifice overclock potential in the name of silence.

CPU: 4770K
GPU: Single Reference GTX 780
Mobo: Gigabyte UD5H
PSU: Seasonic Platinum 660

Case: Thinking NZXT Switch 810 or Phantom 820, but I'm open to suggestions. I'm about to travel to Microcenter to take a look in person. The Phantom 820 claims it has support for a 280/360mm and a 240/280mm radiator, with 90mm of clearance on top.

CPU block: EK-Supremamcy Acetal + Nickel
GPU block: EK-FC Titan Acetal + Nickel (+ backplate)
I've read that these aren't terribly restrictive. (I also like the way they look.)

Fans: I'm a bit unsure about what speed fans I should choose, and whether to go for a fan-controller and/or PWM fans. The UD5H looks to have 5 fan headers with the 4th and 5th locked together. The Scythe Gentle Typhoons are apparently really quiet, but I don't see PWM versions of that. Should I go with Scythe GTs and get a fan controller, or go with something else? Any fan/controller recommendations?

Radiators: I'm thinking the XSPC RX360 V2, 8 FPI, 58.5mm height. With GT fans (25mm?) that gives us 83.5mm, so 6.5mm of clearance (is that enough?).

The 4770K has a max TDP of 84W at stock, and the 780 has a max TDP of 250W. Skinnee Labs reports that with 3x600 rpm fans in pull the XSPC gets 0.039°C/W. So, with 334W that gives 13.2°C over ambient, correct? Since that's outside of the desired 5-10°C range, is there a good 240 mm I can also add to the loop?

Would I get less noise by adding a second rad with 5 fans in pull, by increasing the fan speeds on a single 360 rad, or am I going about this the wrong way?

Pump and reservoir: I've read the D5 pump tends to be quiet, but I'm not sure about manufacteres and pump tops? Is Swiftech a good brand? Does this take a fan header on the mobo or connect straight to the PSU?

Tubing and fittings: The Monsoon or EK fittings look really nice, haven't done too much research about this yet. I know I need to match my tubing ID and OD to the fitting, but do I also need to match the compression fitting to the inlet/outlet on the rads and blocks?

Finally, someone mentioned finding GPU manufacturers allow you to RMA a dead card even if it has been in a water loop. Does anyone know anything about this?

Thanks for any help! I can post photos once I build it as long as it doesn't look like garbage. smile.gif
