Two Swiftech MCP 350 (Laing DDC) in series is good enough for my setup?

[wasserkool]

I received my pump and is totally amazed at its tiny size! Now i am thinking of getting two of them to run in series with the following components:

Nexxxos XP CPU cooler
Mora 2 Pro Radiatior (maxxxracer's fav lol)
Nexxxos NB cooler
Silentstar Dual HD cooler
Two Nexxxos GPU cooler for crossfire..

will two pumps in series provide enough pressure and flow?

[MaxxxRacer]

well ull certainly have plenty of pressure.. about 26ft of it i believe.

but ur flow will still be pretty abismal with the mora and all thos nexxos blocks. It will most certainly be sub 1gpm, but your temps shouldnt be ok as the nexxos XP fairs very well even at low flow rates.

hmmm will the flow be really that bad??

[MaxxxRacer]

yup. you selected the most restrictive components that i know of... all of them infact.

[One_Hertz]

try two iwakis in series ;)

Yeah flowrate will be very low, I just tested a similiar system. The DDC has slightly higher pressure but endresults with components should be close.

Mora 2 vs 1/2 Laing D5, 5 metres of 8 mm ID/11 mm OD Tubing

1 pump+ tubing, no rad
4,62 l/min
1,22 gal/min

2 pumps + tubing, no rad
7,06 l/min
1,86 gal/min

1 pump+ tubing, Mora 2
3,33 l/min
0,88 gal/min

2 pumps+ tubing, Mora 2
4,62 l/min
1,22 gal/min

Some results with added Nexxos XP, this time with 12 mm Tubing and horrible PVC fittings (7mm ID)

2 Laing D5 vs tubing and fittings
10 l/m
2,64 gal/m

2 Laing D5 vs tubing and fittings, Mora 2
6 l/m
1,58 gal/m

2 Laing D5 vs tubing and fittings, Mora 2, Nexxos XP
4,29 l/m
1,13 gal/m

2 Laing D5 vs tubing and fittings , Nexxos XP
6 l/m
1,58 gal/m

Forget about watercooling the northbridge and a single modded 350 will do just fine. Check the pumps in and outlet, the in is much thinner than the out, not good.

[cartmanea]

Since the mcp-350 builds good pressure, and more flow is needed, could two be run in parallel? You might be better off getting a higher output pump though...maybe a single D5/mcp-655?

[Fairydust]

Pumps in parallel are useless for this application. Series is the way to go, more pressure = more flow in such a restrictive system.

[MaxxxRacer]

indeed fairydust is correct in this particular application.. parallel is pointless.
