Single / Dual Pump For Loop

Hi,

Will be looking at setting up a new machine in the near future and will be looking to watercool a 4770k and 2 x R9 290's. Rad wise, the max i'll be able to fit in the case is a 360 and a 240. Rads are XSPC AX360 and AX240.

My question is, will a single EK-DDC 3.2 18w pump be enough for the loop, or should I run 2 of them in series?

I currently have 2 separate EK-DDC pumps with X-RES 100's attached to them. If i'm running 1 then it's straight forward, but if i'm going to run 2 in series, can I run the first pump in the loop with the res attached and then the 2nd pump (with just a top on it) immediately after?

One pump is plenty. Dual pumps are mostly used for redundancy, rather than performance.

A single DDC 18w has more than enough power for that loop

I run a similar loop and its still begging for more

Easily enough. I thought my 4.0 pump wouldn't be enough for 120.5, RAM block, VRM/NB block, CPU block and 290x block, so i doubled up (only another £40, so why not!). I only switched on one of the pumps during the filling of the loop and found it easily to be enough.

I think the whole multi-pump thing applied a lot more back when people were using weak aquarium pumps, as watercooling pumps were not yet available.

My 18w DDC has been running fine for a couple of years with a i7 950, sli 580's and 2x 120.4 rads in the loop.

OK that's great!

I'll go with the single pump then.

Yes you can run to pumps in series if you want so if one fails you have a back up. You don't need to use to pumps of the same flow rate, put the slower one at the front IE: A 800lp/h rear with 600lp/h at the front.
