Pump Question?

RDWest2005 · Nov 29, 2005

Hey guys,
I've been reading my A** off here - lol
I'm about to order all best WC parts from monthly roundup link...

My question lies on this...
I'll be running 4 blocks with black ice extreme III rad

I don't want to run the flo from cpu-northbridge-gpu1-gpu2

i want to split the flo

pump
Y splitter ->
cpu-northbridge from Y 1
gpu1-gpu2 from Y 2
Y1-Y2 back into Y-out to rad

fresh water over cpu/north and fresh over both gpu's

I really want a 4 way splitter and run fresh water over all 4 blocks
but that will be a lot of tubing

will the 12v D5 pump be ok with a Y splitter and the extreme 3 rad?

tx,
~RD

1) The faster the coolant flow, the better an object is cooled
- when you split the flow, flow rate drops
2) Water temperature varies by only a couple of degrees from intake of the radiator to output, not enough to make a substantial difference in temperatures across the blocks.
3) water will take the path of least resistance. That means that if you have a storm, 2x maze4-gpu, and northbridge then most of the flow is probably going to go through the vga blocks, robbing the cpu of preacious cooling power.

Rather than trying to get "fresh water" to each block, focus on the best layed out design. It'll be less complicated, and look better in the end. Plus it will save you a lot of time and heartache when you wonder why things aren't cooling as well as they should.

Ok, with that being said I think i understand a bit better...
how does this sound...

since the vga blocks will restrict the flow more...

run to cpu-chipset - then into Y over both vga blocks and back into Y
then to rad

this should double the flow of the vga blocks - correct?

Using a Y will halve the flow to the vga blocks, if I'm not mistaken.

RDWest2005 · Nov 29, 2005

I may be wrong here - but

i'm thinking if vga blocks internal chamber is smaller and restricts the flow then...

a Y across both blocks will double the flow?

with a pump that will push it

pwnt by pat · Nov 29, 2005

The wyee will half the flow to each vga block. Chances are the chipset block will be more restrictive than your vga blocks so you should just run all of the blocks in series anyway. Also, with series, the water doesn't have to flow through any more fittings. Each Wyee and barb the water flows through creates restriction.

Now that that is settled... back to my main question...

is the D5 pump ok for 4 blocks with BI Extreme III ?

thanks

Should be okay. What blocks were you using?

storm?
maze-4gpu
maze-4 chipset?

Honestly, since it's more free-flow frendly, I'd recommend the Apogee. With four free-er flowing blocks, you should be fine.

Stop screwing around. put everything in series, there is no advantage to parallel.
Look at it this way. The water flows soo fast that it doesn't have time to heat up much, it just comes around again right away.

The only option is two pumps, but all of, or at best almost all of the gain in flow is negated by the added heat load of the second pump.

With high restriction blocks, a second pump may be required and not all of the heat a pump makes is dumped into the loop, only a couple watts for a 25w pump. The BIX3 can handle it

RDWest2005 · Nov 29, 2005

i'm going with...

Apogee cpu block
Danger Den MAZE4 Chipset Block

i was thinking (The Danger Den MAZE4GPU-SLI for Cooling Two (2) Video Cards)
these gpu's are low profile...

I don't need lowprofile with my ASUS P5ND2 SLI Deluxe
i was going after this gpu kit because it comes with copper heatsinks for vga ram

You'll be fine. Just make sure to run all in series and come back with pictures.

RDWest2005 · Nov 29, 2005

Thanks,
And i'm going to take real pics and not with poor ole cam shots

RDWest2005 · Nov 30, 2005

I just made my order a whalla go...
d5 pump
BI Extreme III
apogee cpu block
maze 4 chipset block
2 maze 4 gpu blocks (not low profile) and added the 16 mem heatsinks
3 120mm fans

$474.89

Rad, what case is this going in? Surely it won't fit in the xaser. Even if it did, that case is rediculious-heavy.
