Loop order?

post #1 of 11
Thread Starter 
I am trying to draw out a possible loop direction for an inverted ATX setup and keep coming up with 3 results...
  1. With radiators mounted up top the loop would flow from the pumps thru top mounted radiators >to the SLI gpu's then to the CPU and back to res.
  2. With some extra long runs of tubing I could have them run from from the pumps > to the top mounted radiators back down to the CPU block first > then thru the GPU's and to the res - but I assume it wouldnt look as clean and introduce more tubing then needed...
  3. final option would be to run from pumps thru one res that is mounted slightly lower > on to the cpu block > to the sli blocks > then up through 2 top mounted radiators > and back into the res. Would add some slight complexity to the plumbing but would keep the cpu before the gpu's

So what would be best or does it not matter much since temps would normalize over time??? (The case in question is an M8 and prior to buying fittings I have been trying to map out the case accessories and WC loop setup...)

Thoughts?

Gear involved in case the info is necessary
  • Case Labs M8 case with inverted ATX motherboard tray
  • qty 3 XSPC RX360's
  • qty2 MCP350's running in series using EK pump tops

It really doesn't matter because (you guessed it) temps will normalize over time. Just pick the loop that will use the least amount of tubing. That will give you the best temps and be easiest on you pumps. Also make sure your res is above your pumps in the case for filling purposes. Other than that, go wild you should be all set.

Choose your loop order based on ease, looks and short runs. Loop order means very little. Just have res bwfore pump and higher than the pump for easy filling. Also think a drain line into the loop.

Thanks guys! Good to know - should make it simpler to map out a route for the tubes without having to use too much!

+rep to both of you.

Now figuring out a good way to drain sounds like too much fun

Well you could always put a fillport in the bottom of the back panel of your case and connect it to a spare port in your res. Then when it is time to drain, just tilt the case backwards and open the fillport.

Mine's working great with this order:

Reservoir (just above hard disks) -> Pump (bottom of case) -> Radiator (top of case) -> CPU -> Graphics Card -> Reservoir

The water just goes down from the reservoir to the pump and then all the way up to the radiator and then it just works its way down through the CPU and graphics card before going back to the reservoir. My signature has a link to a thread I created with photos of my build if you're interested (it looks b****ing, if I may say! ).

I built it this way because it seemed both logical and convenient for me in terms of component placement and cooling order, but as said above, whatever component order will still normalise the temperature over time. Just put your reservoir above the pump, with the pump at the bottom if you can. Let gravity handle it from there.

Looking at your system you have the same exact setup as I do and I think I will setup same way I was trying to figure out where the pump would go but looking at your pictures I like the way yours look thanks.

Hmmm- I like that idea! Ima have to check out how I can pull that into the build after I get a few more pieces together. New to the drainport idea since before this new build I merely unplugged a hose and then tipped the case lol... figure this build, draining won't be as simple and need to think through a better method!

Really, it doesn't matter, as people said just use whatever is easiest. I have my res going straight down into my pump, which I suppose helps a little.

My loop goes Res > Pump (bottom of case) > Rad > GPU > CPU and back to the res, but you don't really have that many options with a 480 in a TJ07.

No problem mate!
I think it's a good setup, yeah. And thanks!
Regarding the pump, I stuck it to the anti-vibration pad it comes with but didn't stick the other side of the pad on to the case. Coincidently, on placing the pump at the bottom of the case, I could place it exactly where one hole on the pump and anti-vibration pad aligned with a screw hole in the bottom of the case. This way I could physically screw the pump down on to the case to keep it steady. Granted, with just one screw, but it beats sticking it with a sticky pad!

As for the reservoir, I didn't bolt it down on to the case. I used the two strips of velcro but that proved a bit unstable because of the tubing pulling on the reservoir a bit. Luckily I had some thin cable ties and I put one through one of the reservoir's holes and tied it around a bit of my case (above my SSD) and that's it - the cable tie keeps it tightly bound to the case.

The bit about having the reservoir above the pump and the pump at the bottom just helps for filling. This way, you fill your reservoir with water and the water will automatically go into the pump (due to gravity). Since running your pump dry is NOT something to do, this placement works well for filling. When you switch on the pump, it will "suck" all the water out of the reservoir and into the loop. At that point you switch off the pump, refill the reservoir and switch on the pump again. This is repeated until the water level on the reservoir is mostly constant at nearly fully filled.
