i wouldnt suggest using a Pump with a built in Res dude, go for separates!
You dont need to worry about space with that beasty Lian Li case dont forget

Depending on how many HD's you have - u could use 2 X bayres's

Hey turboduck, I currently have 2x 280GTX's and an i7 920 clocked at 3.5ghz in a single loop with 2 rads sandwiched.

Rads: PA120.3 + PA120.2
GPU Blocks: EK280GTX water blocks
CPU Block: XSPC Delta v3 1366
Pump: Laing DDC1 Ultra 18w

The flow rate is very high due to the 18w pump and very low restriction.

Loop:

Pump -> PA120.2 crossed to PA120.3 -> GPU 1 -> GPU2 -> CPU -> RES

My temps dont get much over 40c on the GPUs and around 50 - 55c on the CPU while gaming.

I can't see the point in spending £200+ on an H20 setup like the above and not having dual loops, espically if you plan to WC the NB (not sure how vital this is on i7 setups though?)

i will defo have dual loops i reckon mate, i will have one for my i7 only and the other for my 285's

Dual loops will probably cost you more like £300+ although making provision for 2 loops I decided to go with one as the radiator sandwich proved very effective.

Turboduck never does anything by half tho

just look at his machine its uber!

turboduck · 14 Jun 2009 at 22:06

can anyone tell me the benefits of having a resevoir on its own and a pump seperate as oposed to a pump/res combo ?

this is pretty much the only thing im unsure on

Cheers

Having the res separate to the pump can make bleeding a little easier. It depends where the actual pump impellor inlet is in relation to the return path of water. If the return "spout" is almost on top of the impeller inlet as it appears to be in the XSPC res top, then some of the air coming into the res during bleeding is likely to get sucked back into the loop, thus taking a a bit longer to fully bleed every tiny bubble out of the loop. The more powerful the pump the more likely this is to happen, though to get round this people will normally just squeeze a tube to slow down flow whilst bleeding. If you have the res separate to the pump then you have more control over where the air is going to go when it gets passed back into the res, normally by judicious case tilting. Apart from that there isn't much difference. I personally prefer the EK series of reservoirs as these have 4 fittings can be fully fitted with standard barbs, so you can do stuff like make the fill line a long tube to make it much easier to fill while you tilt the case about. I guess you can still do this with bayres' and pump/res combos, it just that I'm not sure the fillport fittings on these will take a barb, they look to be a different thread.
