I'm nearing critical mass on my new build on parts I've accumulated over the last couple weeks, and am just waiting on a few more components that should be here in the next week or so. This might be able to go in general hardware, but I'm more interested in comments on the water loop so here it goes.

System
i7-5930k
MSI X99 SLI Plus
4x4 CL16 2600 DDR4
2 x R9 290 overclocked
Various SATA SSDs and HDDs
Seasonic Platinum 1000W PSU
I'm using the R9 290s on my 2500k right now, and under Prime95+Furmark it will draw a little more than 900W at the wall, so I'd expect similar or more with this system.

Case&Cooling
Thermaltake Core X9
2 x HardwareLabs GTS420 Rads
6 x Bitfenix Spectre Pro PWM 140mms
1 x EK XE 360mm rad
1 x EK PE 480mm raf
7 x Swiftech Helix PWM (probably)
3 x Swiftech PWM Splitters
2 x EK FC waterblocks
1 x XSPC Raystorm
Tubing is 1/2"x3/4" Primochill LRT

Flow sensor is this one. http://www.aliexpress.com/item/G1-2...r-1-30L-min-Meter-E2shopping/32274601752.html

Pump is a submersible model I bought off AliExpress, primarily because it can go underwater and I can easily enough rig up PWM control of it.

I haven't tested the head pressure or PQ curve yet and probably won't, but I did fill a 23L bucket on the counter out of a big sink (so a couple feet average head) in a bit over a minute, so the 1200lpm spec is accurate.

Res will be a custom acrylic deal with a 1/2" barb intake and output, and a fill port on top with a valve, along with a waterproof electrical connector for the motor windings. The pump itself will be resting on a foam mat and will only be connected to the res casing through the mat and a section of tubing. Since the pump itself will be water cooled, I plan to sound deaden the reservoir using some sound deadening mat and then attaching it to the case with some rubber vibration isolators. I'm currently in the middle of mocking up a test of this using some scrap acrylic to see how well it works at making the pump absolutely silent before I commit to building the big one.

A couple points I want comments on. I do want to keep a couple mechanical HDDs, and am open to suggestions on how to silence them. I find the noise of them spooling up quite annoying, especially if you get any resonance. I have a few of those cheap 40x40mm copper waterblocks, so I was considering just plumbing those in and wrapping the now cooled HDDs in sound deadener and vibration isolation mat.

I can't imagine I'll be short on rad space and their corresponding fans, so I don't really plan to run any other case fans. The 360mm I'll mount in the front of the case as an intake, with the 480mm on the bottom side as an intake. The two 420s will be on the top as exhausts. With this setup the case air will be heated by the intake rads, but since the GPUs and CPU are under water I don't think the rise in case air temperature vs all exhaust and lots of input fans will make a big difference.
I haven't mocked it up enough to determine the actual routing, but it will be a single series loop. Probably Pump/Res->Flow->GPU->GPU->CPU->420->420->360->480->Pump

The Spectre fans I'm a little unsure of, but it's what was available at NCIX in qty 6 with PWM in a 140mm size at the time I ordered.

Anyway, thoughts or concerns?

that pump is :\


Flow Rate:
1200L/H
Static Head:
15M
Power Consumption:
86.4W
Rated Voltage:
24V DC

its sporting numbers greater then a D5.. infact its sporting numbers greater then my iwaki RD-30, which i find HIGHLY unbelievable....

For the HDD's, there isnt much you can do about the noise.
Also if anything, HDD blocks sort of failed in getting popular, because the performance on said blocks were poor, and a simple fan in front of the hdd's could net simular performance, for a fraction of the cost, even when using quiet low cfm fans.

erm... how big is this pump? its sporting numbers greater then a D5.. infact its sporting numbers simular to my iwaki RD-30, which i find HIGHLY unbelievable....

Probably similar in size to a D5 Strong, but a little longer. Hard to compare exactly though, since the motor is just a three wire brushless DC one, and the control is in the separate external box. I'm not sure how much of the space in a D5 is taken up by the control PCB. It's fun to play with though, that's for sure.

On the HDD, I can understand why the traditional blocks are unpopular. My desire isn't really to keep them really cool though, it's to keep them from overheating if I wrap them in mastic sound deadener and foam so that I can't hear them when my computer is basically idle but I open a file on the drive. Even vibration isolated, the noise of the WB Blacks is excessive. The easier solution to that might just be to move those ones somewhere else and buy a 5400RPM Caviar Green to replace it. That or buy a new NVMe drive when they're available, use my 480GB SATA drive for installs, and finally get all the mechanical drives out. :p
