I haven't even finished my current loop and I'm brainstorming my next upgrade... I want to consider the best WC setup for CPU, NB, 2x GPU w 3 rads (120, 2x 240). Upgrade to NB WC and dual GPUs w/ waterblocks probably wont happen for a month or so... but I want to start getting my head around this 'cause planning never hurts!

I don't want to buy new rads. I think my pump is nearing its limit pushing the 3 rads, CPU and GPU now.

I was thinking about adding another Swifty MCP655 vario pump to the loop to provide more horsepower. I think I would run them both at speed '3' or '4' becuase 2 pumps on full blast would create some decent pressure right?

I'm not sure the most efficient way to do this... Should they run consecutively? Or should the pumps be placed 'half-way' through the loop?

Consecutive: Res>Pump1>Pump2>Rad1>Rad2>CPU>NB>Rad3>GPU>GPU>

'Half-way': Res>Pump1>Rad1>Rad2>CPU>NB>Pump2>Rad3>GPU>GPU>

Or the other option is 2 seperate loops... This would involve more work and I would need a 2nd reservoir. But would probably provide best performance right?

Loop1: Res>Pump1>Rad1>Rad2>CPU>NB>
Loop2: Res>Pump2>Rad3>GPU>GPU

Anyway any thoughts are welcome...

i like he double loop idea and u can always make each loop a different color so why not try it out

water loop is as follows:

custom pvc res=>DDC1(9watt)w/xspc acrylic top=>
Black Ice Extreme GTX 360=>Apogee GT (bowed)=>
Dtek GFX 2=> res

rpm666

1 loop, sufficiently space out the pumps so they each have roughly equal distance between them and it'll be a pretty fast moving setup. I've got two Swiftech 355's in my loop but my setup is slightly different. RAD>PUMP>RES>CPU>PUMP>CHIPSET>GPU>RAD

I would put one 240 and one 120 radiator for the GPUs, since two GPUs makes a lot more heat than a cpu and a NB

two loops is cool tho

Yea, I think you're right. CPU will be a 45nm quad so it won't put out a ton of heat... Dual GPUs will put out much more heat.

i would go with 2 loops, I just trust you are upgrading from your centurion, correct?

I would personally separate into 2 loops.

This will give you better flow per block and it will also help isolate the heat from different components.

So I vote for 2 loops.

I agree, allocate a good portion of your radiators to your dual GPUs.

I vote the 2nd option (spaced out pumps), or 2 different loops.

No the case is a Gigabyte 3D Mercury... take a look at my worklog to check it out, not a very common case it seems.

Yea it looks like 2 loops would be ideal... plus having 2 different colors of coolant would so l33t! clear and black would be sick (both UV blue)

I'd say go with 2 loops. With that many rads and pumps and such you are building yourself a VERY cramped case interior. So I'd say save the tubage and go with separate loops. Besides, that way you can control what you want to be heating up your precious CPU/GPU coolant.

I'd go with 120 + 240 for the cpu/nb/sb and the other 240 for the GPUs. And like what was said, you can go with different colors to give it a bit of panache =P
