So, I'm watercooling for the first time, and want a really quiet setup. I went overboard and bought 4 radiators to stuff inside my 900D. Originally I was going to use 2x 780 Ti's but then the Radeon R9-290X2 went on special, so I bought one of those instead.

What I need to know is, will 1 pump be enough? I intend to use a D5 Vario model, set to about 3, because I dont want to be able to hear anything. This is what the watercooling part list looks like now:

2x Alphacool NexXxos UT60 480mm rads
1x Alphacool NexXxos UT60 240mm rads
1x Alphacool NexXxos UT30 240mm rads
1x EK-Supremacy Evo waterblock with LGA2011 jet plate
1x EK-FC R9-290X2
1x EK-RES X3 250

Its looking like I'm also going to have to use 4x 90 degree fittings to get things fitting in the basement. All fittings will be compression fittings, and I'll be using 3/8-5/8 tubing.

If a single D5 isnt enough, would a pair in series be fine? I dont want to run dual loop if I can avoid it.

yes the d5 is an amazing pump and will be great and if you are going with four radiators plus a gpu, then i wouls say set it to level 5 and it shouls be fine.

nope, your fans will likely be louder than it at 5, i have mine set to 5 and they are louder, i am using corsair sp120 quiet's.

I'll be running NB eloops-PS, which are quieter than the sp120 quiets. The idea for so many radiators was for minimal fan speed.

Anyone else have thoughts or experience on this?

Hi, unless you are going to be doing some REALLY heavy benching you don't need that much radiator. I know the 900d can fit a lot of rads but the real question is, do you really need to. The 2 480's should be more than enough even for R9-290x2. I would have stayed with the GTX 780Ti in SLI but that's just me.

Yes you have overkill on the rads, get the duel D5's if one pump goes out you can still use the PC.

It's more of a "because I can" with the radiators.

I'm a little sad that 3 weeks after i got my 295x2, the 780Ti's had a nice price drop too in Australia. Still would have cost me another $400, but.... Oh well. 295x2 is pretty beastly. Hopefully catalyst treats me nicely, as I found that a friend had issues with it on his 290.

Quick question about the pumps...

Would it be better to run 2 Swiftech MCP350 pumps in a daisy chain both pumps being 1/2 way through the loop. Would it add less stress and less pressure on the lines, or is it better to have 1 pump pushing everything when having more than 3 RADS?

I am looking at a 4 RAD design and I'm just wondering...
