There was a time when I would quite happily tolerate a lot of noise in the persuit of performance, whether it was high flow fans or compressors in phase units. These days though I look for the quiet life and strife with minimising noise but not at the expense of outright performance. Though it's quite easy to get near silence using slow fans, it's usually at the expense of temperatures and loss of overclock, particularly round the GPU and CPU.

The key feature of this build is to minimise moving parts as much as possible, to the point that the only moving parts will be the pump (DDC3.2 18W, perhaps 2 of) and 2 120mm fans running at approximately 3V (minimum output from the fan controller). At 3V the fans will be essentially silent. The pump itself will be suspended via the inlet tubing to negate vibrations and again will be essentially silent once the loop is fully bled and the side panels installed.

I've not decided yet whether to use 2 pumps or 1, though by using the Heatkiller block which has fantastic low flow performance is swaying me to a single loop setup with the GPU and MB cooling in series. Alternatively I would use the second pump for the CPU only back to a common res and then the other pump would handle everything else.

I've added a 1" hole for the fillport to the top of the case for ease of cooling.

To cool everything I'm going with Cape Cora radiator tubes, each one is estimated to handle about 25W of heat load at a reasonable differential temperature, in total I have 22 tubes meaning that they have about 550W of cooling capacity.

I'm going to mount 11 on each side of the TJ07 and have them tubed in parallel to reduce the pressure drop in the loop and therefore increase the overall flowrate.

The aim will be to have sufficient cooling to overclock my D0 920 to 4.2-4.4GHz stable.
 
Been doing a bit more work the past couple of days:-

I was hoping to add heatsinks to the RAM PWMICs but the gap between the power socket/capacitors and the chokes isn't big enough to fit in even my tiny heatsinks.

And once done, a dry run so to speak just to check everything is still working.

And one of the side panels drilled out for mounting the tubes.
 
Looking good.

You do need to pop on MSN at some point though, if you can spare the time away from Ulduar! :p
My temporary setup has lasted slightly longer than I had been expecting, I'll be back on MSN once this one is finished. :cool:
Looking good :)
Did you start the board with no cooling on the cpu, or was the block just installed and no cpu :p
Started it up with no cooling.
 
I think the hole is designed for dual cpu boards in mind. It's a shame they don't have a hole at the bottom into the PSU section as it would be handy for the power cables being tucked behind the tray as well.

Going to have 2 speed controlled fans plus SSDs.

i thought about getting a solid backplate but ended up deciding against it
I'm not to keen on it, because of its shape you need to use additional spacers to lift it off the back of the board

Got a bit more done today, decided on two pumps, one for the CPU, one for everything else. From the res, it goes to pump 1 and on to the CPU and back to the res via a common line. For pump 2 it goes to the GPU, the power regs, the chipset and then out the back to the radiators (each side in parallel) before returning to the common line.
 
Type of tubing doesn't really matter when it comes to damping the pumps, I've been mainly using some old Waterchill 10/8mm (it's slightly more than 10mm OD making using 10mm nuts tight) tubing but I've not been able to find a source for it. Outside the case I've used some cheapo 10/8mm PVC that kinks fairly easy.
