Two loops using same res?

[CreAtiv3]

Afternoon all

Been thinking about adding a second loop into the system to watercool a GTX 480.
Is it worth running two loops off of one reservoir?

Something like this looks as though its up to the job but my main concern is how big an impact it could have on the flow.

What would impress me more is a reservoir like the one I linked to that has some kind of divider running through the middle that would keep the loops separate but still one unit.

Any recommendations folks?

Another option would be to avoid a reservoir all together and just have two separate t-lines going to fillports after thinking about it...

I would use Y-connectors and two pumps. I wouldn't use t-lines because flowing water absorbs air and is only good if you want to build a vacuum press.

This is something I've been recommending if you've got a radiator in both loops.

Separate t-lines or two loops sharing a res?

Plan would be along the lines of:

Loop 1:
Pump A > 120.3 Rad > CPU > PWM's > NB > EK 250 Res > Pump A

Loop 2:
Pump B > 120.2 Rad > GPU > EK 250 Res > Pump B

The only thing the two would share is the reservoir.

If you use Y-connectors does that not mean both loops would be contending through a single tube?

if you've got the same pumps in both loops, i'd imagine that there wouldn't be any starvation of flow.

if they're different pumps, you'd have the lesser pump receiving less water.

won't this cause a massive pressure dump into the res tho? not in that it'd make it blow open but you'd have an uber powerful jet of water in the res...

A multi option res is what you need,

google phobya balancer.

I'm now using one on my loops Graphics and CPU, it works well

I'll post some piccies up of it soon

i had a XSPC one that used 2 pumps and one res, but it is EOL...but you can still get them if you shop about.

In fact XSPC still make one that is one unit but with the res split just as you want...go to xspc website and have a look, and as it hasn't got one of there own ****ty pumps in you it wont fail (I HATE YOU!!!!!) and take out your CPU and Mobo
