Hi-Flow DDC Pump

coolmiester · 06-30-2005, 04:29 PM

I've already done a run through on how to Mod a DDC inlet to 1/2" to 1/2" but this one is a bit different so will add it to the log anyway

The pictures speak for themselves really but i'll do a running commentary best i can between pics (and there's quite a lot of them so be warned)

Started off by demmeling out the centre section

but this time once the hole was drilled used a 9/16" UNF tap

so the Danger Den Hi-Flow barb screwed in like so!

Then filled it up with 2 part Araldite and left it to go hard..the glue that is

I also cut the thread from another DD barb and glued that on the out-let as well

Now for the fun part. Filled the top of the pump with 2 part body filler...

....just like icing a cake

Then sanded it down with ruff sand paper and filled the low spots with more filler.

Filled and sanded a couple of times then moved on to smother wet n dry paper till all the imperfections were gone

Masked the barbs off

then a couple of coats of primer followed by a light sand with 2000 grit wet n dry

After the primer, gave it 5 coats of the closest metallic blue paint i could find that matched the rest of the case and also chopped the mounting lugs off the bottom bit of the pump and gave that a few coats of aluminium paint

The colour is not an exact match but near as dammit

And finally along side a standard Laing DDC

Sorry for all the pics :duh:

like i stated on another forum, that's a great mod. i love it. i have a pint of Dodge Viper GTS Blue Pearl that i'm thinking about using on a case mod, it looks kind of like the CoolerMaster Case blue but deeper and w/ metal flakes mixed in.

How big a difference did it make to flowrate?

Ls7corvete · 06-30-2005, 11:02 PM

Very nice, cant say I would go through that much trouble for looks though.

Installing a 1/2" fitting into the front of the DDC pump casing can almost double the flow! My original article and test results can be found here...

Does anyone have a source for just the front cover?

NEWBY ALERT:

Your mod is a GREAT idea, RoboTech. But, I have to warn any unsuspecting newbies not to expect a doubling in flow or in cooling performance. Please read RobotTech's article, and don't jump to conclusions!

Even in a good scenario (low resistance waterblock and low resistance radiator), you were getting around 46.17% increase in flow, not 100% increase in flow. The ability to get 100% increase in flow only happens in bench test scenarios where nothing is attached. Again, that is a HUGE win for performance, but not a doubling.

Then, for what really matters: temperature. This is too hard to predict, and most of us here are smart enough to avoid any glib statements of what YOU will get in a system. However, don't expect your CPU temps to drop 10C by making this mod. You might get 1C to 4C improvement depending upon your setup, and that's just pulling numbers out of thin air, because IT DEPENDS UPON YOUR SETUP.

Thanks Brian...

You are absolutely correct! Yes, the pump "free flow" can be almost doubled but real world system flow will be much less. Still, every little bit helps.

Brians256 · 07-07-2005, 02:51 PM

Now, if only Laing would produce this pump with a better inlet so we wouldn't have to do their work for them....

Jag · 07-07-2005, 06:13 PM

...and resolve the misterious pump failures also.

EPiDeMiC2k2 · 07-08-2005, 09:37 PM

Did the barb on the outlet just slide over the plastic peice? or did you have to do some grinding?

maxSaleen · 07-08-2005, 10:39 PM

I'd like to see how this performs with a Storm G4 (1/2").

CYberDruid · 07-10-2005, 10:41 PM

I'd like my Storm G4 in my hand right now!--Cool Mod--thanks for the walk through

EPiDeMiC2k2 · 07-11-2005, 01:03 AM

Ive been running a storm for quite some time. Ive been using this pump unmodded along with it. I'm gonna do this mod this week, I wonder how much of a difference I will see in temps.

Yeah, just chopped off the / \ bit and a Danger Den barb slides right on.

Laing DDC with 1/2" step up adaptors = 7.2 LPM
Laing DDC with 1/2" modded inlet = 12.2LPM

Test carried out with a 5lt container and a stop watch

Here is another walk through for modding a Laing DDC to 1/2" which might help also
