2nd Rad Help

doc_colton · 11-07-2003, 11:36 AM

I added a MCW-50 T to my set up and my water temps are up. I'm running a Dtek WW, a Dtek Heater core and a Swiftech MCP600, 1/2" I/D tubing. If I were to add a second rad, and given MCP600 is a high pressure, lower GPH kind of pump, what would be the best layout. I was thinking series, pump -> rad1 ->
CPU -> rad2 -> GPU -> pump.

hey there,

just route it the way you can get away with, with the least bends and shortest hoselength. as i have learnt from BillA there is no advantage whatsoever to be had from changing the order of components.

I suggest to try a few different arrangements. I run my 2 rads in parallel and get good results that way. Experiment with series (your suggestion) and parallel and let us know which way works best in your system.

Recently acquired my second BA rad and connected it to my system. Rads are setup in parallel with Y splitters.

pump -> Y -> 2 x BA rads -> MCW5002A -> MCW50 -> res -> pump

I suspect that the inclusion of the 2nd rad has deprived my swiftech waterblocks of their much need water pressure,
causing it to loose 100mhz in overclocking potential.

Any potential solutions??
Pump used is a Sicce Extrema 2.5m 2500lph

Did you try running them in series?

g.l.amour · 11-14-2003, 02:16 PM

a problem that i already pointed out in a thread of its own.

parallel, pressure won't drop more (in the WB) than it would drop from a serial setup. however, you will need quite a stronger pump to prime the air out of the rads than with a serial setup.

temp wise i haven't been able to measure this.

the situation was

maze2 / 2hc's / 1048 in serial setup i would get a certain temp result of the cpu

trying those same components parallel didn't yield ANY measurable temp advantage; however the tubing that exited my rads and was going down to the res had these big bubbles that didn't get blown to the res

i changed that setup to a 1250 pump, (set me back 100$) and the bubbles got blown out nicely, but i didn't get a temp improvement.

that leads me to my conclusion that if u can get the setup routed shorter and more conveniently serial then you will almost always be able to get away with smaller pump and get the same temp results. ofcourse nikshub will not be having that problem, since, if i recall well, he has an iwaki superhead pump.

edit: here's the thread i once started about the serial parallel enigma:

I have access to a second pump. I'm assuming if I just create two separate systems, a pump and rad for each waterblock, I would be getting better performance than trying to incorporate everything into one loop.

That's a bit the situation here.
If you have access to 2 pumps, and are wiling to use them, serial setup will sure boost your performence.
The 2 rad's should be more than capable to remove the heat.

Also, your CPU will give about 100W of heat, the Northbridge and GPU about 50W

Math is easy... combined through the rad's will give you a temperature drop on the CPU, and a raise on the GPU/NB, compared to a dual loop system (in theory that is)

If your rad's are big enough, then there is no gain.
You can not go colder than ambient temp. If the water temp is more than +/- 8 degrees above ambient, use the two rad'sin one loop. If it is lower, you can try if one rad can handle the (CPU) load.

A raise of 3 degrees in water temp, should give you about 1 degree cpu temp raise. (depending on your setup)

doc_colton · 11-17-2003, 06:50 PM

Yes, but there is a TEC on the GPU waterblock which generates 115W according to Swiftech (I don't use a Northbridge WB). I thought given the peltier was generating it's own heat and the CPU is non-pelted, that totally separate loops would make more sense.

fhorst · 11-18-2003, 01:44 AM

In that case, you might be right. I'm not into pet's that much, only thing that I was told is that a 115W pelt does not produce 115 w of heat.

Wll give it a try and let us know the results!

Have fun!
