Few questions about upcoming build

[Viktor Karlsson]

I have 2 questions about an upcoming build.

1st: Will the pump that http://www.aquatuning.se/product_in...eh-lter-Dual-Bay-5-25--f-r-1-Laing-Pumpe.html is made for be able to pump the water through 1 240 rad, 1 360 rad, 3 gtx 480 EK blocks, 1 CPU block, 1 Rampage 3 Extreme EK waterblock and a RAM waterblock or should I get 2 pumps for that kind of loop?

2nd: With the Rampage 3 Extreme having 8 4-pin PWM connectors, will I be able to use the Cooler Master Excalibur without them beeing on full load all the time? Since I'm thinking about getting 5 of them to cool a 360 rad and a 240 rad in my upcoming build and I want the computer to be rather silent.

I have a 4 pin CPU connector on my current crap motherboard and when I use a PWM fan on a 3 pin MB connector it'll turn into a jet plane but when I use the PWM fan in the 4 pin CPU connector it'll blow less air but gets close to silent so the "2nd" question is more like a question about the "none" CPU connectors on the Rampage 3 Extreme motherboard will make the fan go faster/slower depending on the heat on aswell.

Cheers!

hey dude glad to see you come over from YouTube:

1st for all those 480's you need two loops, one for cpu and one for GPU.

Second the 360 and 240 would struggle to cope with just the cards as they are freaking nuclear reactors.

I wouldnt plug the fans into the mobo cabling will be a nightmare get a fan controller.

fan on mobo wise you need to set it in the bios (pwm) its all set in there for how much the fan spins.

I'm glad to be here man

Are the 480s really that boiling hot even with watercooling? :|

I've actually looked into the part of connecting the fans into the mobo and I dont think it'll be that big of a problem.. I'll be using an Obsidian 800D wich have some amazing cable management + the mobo itself have the plugs pretty close to the edge of the board so it shouldnt be too messy inside the case, but I'll be looking into it

Anyway... the pump, you think it'll handle a loop like that or is it a crappy pump even with a smaller loop?

The loop will be: Res/Pump > 240 Rad > GPUs (down to up) > Mobo > 360 Rad > CPU > Memory and back into the Res/Pump.

You dont think the 240 Rad will handle cooling the liquid before it hits the GPUs even though it just passed the CPU and memory after leaving the 360 Rad?

Uh...Oh...

Here comes the wrath of Tom

no comment dear god

one loop is a no mate with those componants. putting a rad before gpu's and then in another loop after will make NO difference to temps as its a sealed loop.

Wont the 360 rad which the water goes into before hitting the CPU lower the temp on the water that came from the GPUs?

Technically yes, but in practice, a 360mm won't take the temperatures down enough for your CPU. And as Tom says, its a sealed system so the temperatures equilibriate over the loop in the end. You need two loops as GPUs are a lot more tolerant to high temps than CPUs are.

The temperature of the water in my loop (2 5970s on a quad radiator) after a furmark session will be 40C, so the cooling for the CPU would be pretty bad, as the delta T between the CPU and the water is pretty small. I run two loops, 240+120 for the mobo and CPU and 480 for the graphics. That case is easily big enough for two loops, so there's no reason not to.

Aight, I'll look into it

It might even be possible to mount 2x240 rads in the lower part of the case aswell with some modding
