How is this setup?

Tweekster · 10-20-2001, 01:52 PM

I've been tweeking PC's since the NEC V20 days (XT's), but this is my first try at H2O cooling. Just wondering if you guys with experience would checkout my plan before I pull a bonehead:

System:
Asus A7M266
Athlon XP 1800+
512 megs Crucial DDR @ CAS2
Enermax 365 PSU
Nvidia TNT2 (GeForce3 Ti 200, when released)

Cooling:
DD Maze2 - 1/2"
DD Chipset block - 3/8"
Eheim 1250
DD Heater Core - 1/2"
120mm fan or 8" car fan (see below)

The heater core, reservoir, pump, fan and 12V power supply will be in a separate box with just the cooler lines running into the cpu case. I'll have to build junction blocks to tap the 3/8" lines off of for the chipset cooler, which will probably have restictors to limit the flow to the chipset and increase the flow to the cpu. As far as fans go, I can run a 120mm or use an 8" 12V car fan that moves 800CFM. If I use a variable power supply on the 8" fan, I can dial it down to reduce the noise, but still pull more volumn than the 120mm. My goal is to have system that is quiet and worry free. What do you think? Any thing you would change?
Just wanted to say, Procooling.com is an excellent resource and very well designed, I have spent the last few weeks digesting all the info, thanks

Few things:

Why even watercool on the A7M266? It doesn't allow for overclocking (expect for FSB) so aircooling would be fine.

As for the setup, looks awesome. Actually it virtually identical to mine except I have a GPU block instead of a chipset. One thing I would change is to use a 1/2 inch chipset block. That way you can put it inline with the CPU and improve its performance while reducing the complexity of the system.

Mine does!....I have added the DIP switch and resistor mod, so I have full multiplier control

Forgot to add, I previously ran a 1.2 T'Bird @ 10.5 x 145fsb, Vcore 1.85, with various HSF's and case fans, my CPU load temps would hit 52C....28 over Ambient.....now with my untouched XP 1800 I'm getting 50C-51C with the exact same setup, but with too much fan noise (damn Delta). I would like to see the CPU temp in the low 40's, and much quieter. Is that realistic?

By running the chipset block in parallel with the CPU with a restictor I could maximize the flow/cooling to the CPU, is that assumption wrong? Run the chipset in series before the CPU?

Hehe, I did a similar mod on my ECS K7S5A, added multiplier control to it.. Nice considering it's only a $52 board..
Anyways, your setup sounds like it will work well.

You never want to do anything that hurts flow to the CPU. Even with a restricter, the chipset will be bleeding off flow that could be used on the CPU.

By putting it in serial you avoid this issue and give both blocks the full force of the pump to work with. Furthermore, this way is much simpler. No need to worry about balancing flow between the 2.

Nice touch on the mod. I didn't even know it was possible on an A7M266.

It's technically possible on ANY Socket A board. There are a set of universal instructions.

I don't agree. Putting block in series increases flow resistance so putting them in parallel is probably the best.

With a 1250 pump I'm willing to bet this is marginal. When I added a 1/2 inch GPU block to my otherwise identical setup, I saw no difference in CPU temps at all. As best I can tell that pump is limited enough by the Maze2 that the small amount of addtional resistance from an open block is easily overcome.

How much of the flow would you need to even give the chipset? Maybe 20% total? Thats 20% less for the CPU then. In serial there is no way one block will reduce loop-wide flow by 20%. Not to mention in serial the chipset itself is cooled better due to higher flow.

Thanks for all the replies!

I picked up my Geforce3 Ti 200 last night, and it definitely adds heat to system........so, I think I'll get a 1/2" GPU block and live with the factory chipset fan for now....I'll experiment with series and parallel,and let you guys know how the temps workout.......maybe with H2O I can push the Ti 200 to Ti 500 speeds..hehe
