dual pumps

[mattymat04]

I have a few questions

two swiftech 650's

dual pumps parallel or series?

does a second pump add to much heat into the loop?

the system

swiftech 650

danger den blocks all 3/8"

cpu,gpu,northbridge

pa 120.3 rad fans come on once passive cant cope with temps

innovetek ulta passive rad with 3/8" fittings was worried that it would only accept 1/4" fittings but 3/8" totally fit no restrictions with the bore

dual 5.25 res

all in a lianli 2000 case more then enough room

I would have liked to stay with all 1/2" but the passive rad the bore only accepted up to 3/8" and I didnt want a bottle neck.

I have not put this all together. I never ran a setup with this much water moving around that is why I was thinking another pump in series.

due to this being a mostly passive system though I am a bit worried about the added heat that another pump might introduce to the system.

thanks for your advise and comments

Doubt you'd see too much of a difference with dual pumps mate, i wouldnt bother as its extra tubing/mess etc

You would see a difference if you set it up correctly for sure.

If you set it up to have 1 pump soley for the CPU and the other for the GPU and NB blocks then you will have basically 2 separate loops running off the 120:3. I was going to do this in my last system but didn't have time as the Mach II arrived before I had the chance, so went straight for GPU cooling loop.

This would lower temps on both things.

Agreed with boardy and this is the exact path i am taking atm! Seperate loops is the way to go and will help the temps decrease

Thats the exact path i took

Two CSP-750's

One for gpu and NB and one for CPU all into a 120.3 rad.

Temps are good.

Cpu load is under 40 as is the gpu.

X2 4400 @ 2.8ghz and an x1900xt

Pretty easy to set up too and very nice to change cpu's because theres plenty of slack as it isnt connected to the gfx block.

Set up like this

I have to say the only thing I'd change there is going

res -> pump -> rad -> block

That way the water is at it's coldest when it hits the block

yea. very minimal differences tho (we're talking tenths of a degree)

ok so lemme get this straight instead of

two pumps in series to increase head pressure and sending it like this

pump>>>cpu>>>gpu>>>chipset>>>passive rad>>>pa120.3

or two pumps in parallel to increase gpm

better is a two loop system?? like

1 loop....pump >>>cpu>>>passive rad>>>pa120.3

2 loop....pump>>>gpu>>>chipset>>>passive rad>>>pa120.3

so then I would be y'ing the two loops at the passive rad correct?

thanks for the replies this is getting interesting

 

[boardy]

Yea pretty much right,

Personally I'd do it -

................................Pump....-.....CPU

Res - Rad1 - Rad2.................................Res

................................Pump - GFX - NB

Your right about Y adaptors tho I show that a little clearer in that loop setup.

why not just get anouther single rad with one pump like this, pump>>>rad>>>cpu>>>second rad>>>gpu>>>chipset>>>res>>>
