Greetings All,

I am transplanting my existing gaming/folding rig to a new case with WC - intent is to finally allow decent O/C with silent/near-silent operation.

The following existing parts will be moved from a Corsair Graphite Series 780T into a Case Labs Magnum SMA8:
  • MB - Asus ROG Rampage V Edition 10
  • CPU - Intel i7 5960X
  • GPU - 4x Asus GeForce GTX Titan X
  • PSU - Corsair AX1500i
  • RAM - 8x G.Skill Ripjaws 8GB DDR4 2800GHz
  • Storage - 1x Samsung M.2 XP941 (on MB) + 2x Samsung 850 Pro 1GB
  • Optical - 1x LG BH16NS40 BR r/w
  • Fans - Silent Wings 3 High-Power (2x 140mm front intake, 1x 140mm rear exhaust)
  • O/S - Windows 10
The CPU was cooled via a Swiftech H240-X AIO which is now deceased, and the GPUs were stock with no additional cooling.

I will be installing 2 WC loops in the SMA8:
  • CPU: Res -> Pump -> CPU -> 360mm Rad -> Res
  • GPUs: Res -> Pump -> 560mm Rad -> GPUs -> Res
CPU loop is an EKWB EK-X360KIT, radiator will be top mounted, with 3x Silent Wings 3 PWM High-Power 120mm fans in pull (exhaust) configuration.

GPU is a collection of EKWB res/pump/rad/GPU blocks+terminal, radiator will be bottom side mounted, with 4x Silent Wings 3 PWM High-Power 140mm fans in push (intake) configuration.

I will be using soft tubing, and EK coolant.

I haven't decided on exact fittings just yet (other than that they will be compression fittings) as I want to see all the parts in the case first before deciding how best to route and connect the tubing (might need a few 90/45/30-degree elbows for example). Will also fit a fill-port into each reservoir, and a drain port (via T-junction and tap/cap) on each loop.

Case fans will be:
  • 2x Silent Wings 3 PWM High-Power 140mm (front intake, connected to CHA_FAN1 + CHA_FAN2)
  • 1x Silent Wings 3 PWM High-Power 120mm (rear exhaust, connected to CHA_FAN3)

In the Corsair the Swiftech was connect to W_PUMP, and I was using Asus Fan Xpert to control the pump and all the fans. With the SMA8 my dilemma is how to connect and control the two WC PWM pumps and all the rad fans (hoping I can still use Asus Fan Xpert)...

The MB provides the following potential connections:
  • 4-pin W_PUMP + H_AMP_FAN co-located near the bottom edge of the right-most RAM stick
  • 4-pin CPU_FAN + CPU_OPT co-located at top right corner of MB
  • 5-pin EXT_FAN near bottom right corner of MB
For the pumps: W_PUMP is obvious and I will connect one of the pumps (probably for CPU loop) to this. Should I connect the second pump (for GPU loop) to H_AMP_FAN, or to CPU_FAN or CPU_OPT ? Unfortunately the MB manual does not say much about the use of any of these…

For the rad fans: since I don't think a single MB fan header will support 3-4 high-power fans, I'm thinking two Swiftech SATA-powered 8-way PWM hub (I already have one from the Swiftech H240-X AIO) or the equivalent Silverstone product - tie all the CPU-rad fans to one, all the GPU-rad fans to the other, and connect them to CPU_FAN and CPU_OPT respectively - would that work ?

Or will I have to look at a more complicated solution such as be looking at some other solution such as an AquaComputer Aquaero 6 ?

Regard.

PitBullCH.
