AFAIK, :yepp:
nice, saves me $15 :D
another little question. How much does a Y fitting restrict flow? Im thinking of using it as a fill line placed right before the inlet of that pump.
Not much, but I would think a T should be better. I wouldn't worry about a single Y or T, though.
I just done this mod to my 10w Laing DDC and it worked for me, I haven't got round to fitting the pump into my system yet, but I have tested it in a small loop outside my case, and it seems to be just fine..
Very simple mod to do, I managed it, and I'm hopeless with a soldering iron!
Great :D Should be placing my order today.
Another question lol. Which is a better top?
http://www.performance-pcs.com/catal...ducts_id=24824
vs
http://www.performance-pcs.com/catal...ducts_id=22700
did that, just the other way with my ddc...
EK X-top V2 is slightly better ;)
About pump I havent heard that swiftech would be already distributing DDC-3.15 and 3.25 under same names mcp350 and 355 so that one still should be rebranded DDC-3.1 and 18w mod would work fine! ;)
Hey guys just got my pump and it looks like this:
http://i265.photobucket.com/albums/i...d/IMG_2640.jpg
Where do I solder?:confused:
Like this?
http://i265.photobucket.com/albums/i...ted/mcp350.jpg
Maybe I got a DDC3.15? :( It doesn't match Martin's pic.
http://i265.photobucket.com/albums/i.../mcp350mod.jpg
What does your impeller look like?
I'm gonna say that you got a 3.1 with a newer PCB on it. It could be that Laing is using the same PCB for both the 3.x and 3.x5 models with just some slightly different components/better windings. Last I heard, Swiftech hadn't gotten any 3.x5 yet and that they (3.x5's) actually had a 2 tone impeller.
For your original question, it looks like you'd need to move the yellow wire over to the left as you suggested.
Thanks waterlogged :up:
Should I just bridge them or actually move the wire?
how sure are you on moving the yellow cable?Quote:

Now you got me wondering if his pump is mislabeled. :confused: Did you ever get to head pressure testing the pmp400 after your flow tests? That may very well be one of the few true ways to tell the difference. :shrug:
@ Burninator, does it appear that there is another label underneath the Swiftech label. . .can you peel the Swifty label off and post what the other label says?
There was another label but nothing saying pmp400...
Guess it is a DDC3.1?
http://i265.photobucket.com/albums/i...d/IMG_2649.jpg
pmp400 is what Koolance calls the 3.25, at least, this is what we've been told.
As for your dilemma, I'm suddenly not so sure anymore. :shrug:
So if I were to re-solder the yellow wire on the left... any ideas on what would happen if it wasn't the right thing to do? Boom headshot to my pump?
That could be one outcome.
Myself, I'd still go ahead but after some careful observations of the PCB and probably some poking and prodding with a DMM. I've now torched enough hardware in my lifetime that it almost doesn't phase me anymore. The 3 I took the hardest were all DDC-2's, I still weep over losing them. http://www.thesmilies.com/smilies/sad/sad0002.gif
shoot 3.1s LOL...i'm checking my pm400s now...i'll poke the stickers off maybe there is a label behind it..Quote:

thanks
here you go :)
http://i265.photobucket.com/albums/i...d/IMG_2653.jpg
awesome picture dude
koolance pmp400 is not ddc 3.25 based on the pcb...i have 3 pmp400s here...
koolance specs on their website indicate ddc3.25......what do we call this bs?
3 difference i note are:
1. housing different.
2. impeller is two tone
3. cabling i think is custom
if mcp350 is ddc3.1 and swiftech's specifications are true..then koolance have some explaining to do with their specifications...
im getting a laing ddc 3.25 at jab-tech hopefully its the real version...
i'll let you know how it is soldered..or if the pcb is even different...
for performance i've tested these pmp400s aka ddc3.1....they're as good as mcp355's
So you're saying that the pump I have performs just as good as a mcp355? :confused:Quote:

based on your picture.....the pmp400 that koolance is selling is the same as your pump(ddc3.1)....take note of the 3 differences...
here is the thread..where i have the a mcp355 vs the koolance pmp400
http://www.xtremesystems.org/forums/...d.php?t=221391
************i can't find my sd card LOL...
My pump is mounted right now, but I have the 18W version, would mine just be soldered from stock which I could then unsolder to make it 10W (For more silence)
my two pmp-400 are also labeled 3.1 !!! what does that mean?
A conspiracy!! :fact:Quote:

@Hondacity, any chance you can do a dead head pressure test on a pmp400? This will give a definitive answer without having to wait until Monday.
i got no manometer...
and i ordered usps priority it will take awhile :D
but yeah the pcb naming ..i'm not sure of..i'll open up 4 more pumps here...and observe pcb versions of ddc3.2's supposedly....
Don't need a manometer for dead head, just about 25'-30' of tubing. :D
How about some RPM readings :shrug: ;)
just the pcb .Quote:

@Honda do your ddc3.2's have similar pcb's as my 3.1? Would love to know what to solder to get 18W performance out of my mcp350 :up:
Still no one that knows if you can go from 18W to 10W (Or put a switch on so you can change between 10 and 18 when the computer is off)
so is there no hope? :(
Maybe I'll just return it...
just unsolder it i've seen it mentioned before :)Quote:

From a manufacturing cost standpoint it would still make sense that they are the same PCB. I'm going to guess that you bridge across the yellow to both contacts, but I would wait until someone with a newer 3.25 can take a picture and share it if you can't handle the loss...
I do know that a DDC2 can only handle 30V for about 10 seconds (Failed variable PSU switched over to 30V and fried it). It was sure ripping while it lasted!!!
Still no reply from Koolance regarding the pmp-400 :( ,I'm thinking if it turns out to be a ddc3.1 why in earth do they cost more than a 3.2 " mcp355"
to those that msgd me..sorry..was working the past days...jab-tech i thunk sent it already...i hope its on my door step...
will post pics in 2-3hrs driving currently :D
I received an mcp350 from jperformance last week and it has the 3.3PCB just like the pic but without solder connecting the far right tab.

thats the old mcp350..that martin showed the modification on...
the thread starter's got the new pump... look at post #9 and #25 of this thread
**usps hasn't delivered my pumps..ordered it friday..sheesh
slow lol. how's the wiring look on your pmp400's? same as my mcp350?
Sorry I was replying to the OP since he asked if the pump in the link was moddable. I just received that pump from them less than a week ago and posted a pic up. Not sure how he got a different one when they were ordered about the same time.
pmp 400 (ddc 3.1?)
http://i24.photobucket.com/albums/c5...5/IMG_0179.jpg
mcp 355 side by side with pmp400 (ddc3.1?)
http://i24.photobucket.com/albums/c5...5/IMG_0181.jpg
That is a lot of pumps lol. I'll trade my 3.1 for one of your 3.2's ;)
i just received 3 pumps...all the pcb's are identical to the pmp400s...and like your ddc3.1 10w...
mine are labeled as 18w..i don't know what else could be seen..i'm studying the pcb UL or UR inscripted on it...dunno what they mean ...
ddc3.25 and pmp400 from the right...
**burninator...i don't know how you can mod that bitsch LOL
http://i24.photobucket.com/albums/c5...ity25/8888.jpg
:(. Since my 3.1 appears to be the same as your 3.25's how bout we just trade? LOL
Man this sucks... Now I'm stuck with a 10W pump...:mad:

Alright, I'll do that. Would it be ok to run the pump dry to get a RPM reading or should I set up a small loop?
you'll kill it :D
Lol. K.
Set it up and got a reading of 3900RPM, that good or bad?:confused:
they are identical right? so the pmp-400 is a 3.25 !Quote:

im setting up my scope...gimme 45minutes
my classified board ...reads 4550-4585rpm :)
Only posting pcb shots that have already been posted... will be running PQ in the near future.

skinnee
do you have the 350?
nope, MCP355's and PMP-400. Never had the notion to buy the 10w version.
thanks
if you look closely at the PCB's... the traces are different.
The only difference I'm seeing between the OP's 3.1 and the pics skinnee and Hc have posted are the numbers on the sticker. . .and I've already stated that Laing has a long history of chaos in that department. :rolleyes:
Did you get a mano?Quote:

no mano...i'm saving up for a gtown :D

do you remember your rpm for the 355? was it around 4300?
In that case. . .Dead head Dead head Dead head Dead head Dead head :DQuote:

Hi ####,
Unfortunately, we don't specify, nor do we guarantee, a specific version of our pumps except our own SKU. While it is true that most of the PMP-400s are 3.25s, we do still have some lower versions as well.

wait, so they don't check the version, but just make sure it performs at the right spec? Or are they screwing some people over?
No, thats not how I read it. Basically he is saying there are 3.2's and 3.25's available through vendors. The supply of pumps changed from Laing or the Laing distributor... product revisions happen and are a normal part of a product life cycle. The Koolance PMP-400 SKU did not change as a result of the revision.Quote:

i also have pmp400s that i can test...
if you have a pmp400 that performs like a ddc3.1...you can say anything you want...
the email...is straight forward..they don't know their inventory much...
but my question to Kolance was :Quote:

The only difference is the sticker and the impeller on the OP's, the pcb's are the same for all of the PMP-400's. I can swap impellers between the two, same size and the difference being the bottom piece of two molded pieces.Quote:

If it's multicolored (Blue and brown/red), it's supposed to be a 3.x5. :shrug: The way Laing screws around with the DDC line, I'm starting to think pressure testing (whether it be dead head or manometer) is the only definitive way to tell what pump you got.:rolleyes:Quote:
Originally Posted by skinnee

quattro_, what RPM does your pump run at? If it's 4300+ at 12V, you're fine :)
DDC3.1 RPM is ~3750RPM at 12V (if memory serves me right).
DDC3.2 RPM is ~4350RPM at 12V and ~4500RPM at 12.4V.
My guess is that DDC3.x5 RPM numbers are very similar ;)
Impeller color + RPM readings will tell you everything you need to know :fact:Quote:

Not if they decide to drop 1 of the "supposedly current" impellers. ;) Like I said, Laing loves to screw with the DDC line for some reason. Who knows, they may start making a purple impeller for all DDC's just because they can. :ROTF:Quote:

What was the difference in flow rate between 3.2 and 3.25 for you with the KFK (Koolance Flow Killer) setup? Like 3%?Quote:

1) Aside from color, are the impellers different?
2) What are the running RPMs with the stock top or with a mod top (it's important to note that above ~2.8GPM, the XSPC tops cause the impeller to knock against it and RPMs to drop, so a loop with just tubing is going to cause measurement issues because flowrate will be near the max possible).
3) Are there any other physical differences?
4) Does power draw noticeably differ? (yes, not everyone has a DMM....this is a bit of a last resort observation)
EDIT: this I can say with almost 100% certainty: the most important factor to DDC3.xx performance is going to end up being RPM. If you're at 4300+, your end loop performance will be imperceptibly close to 'ideal'
@honda: do i get to keep it :D lol
I am you knucklehead... :DQuote:

honda will have my 350... worked out a trade with him for one of his ddc3.2's :)
Wow and no update......
So in fact it means, that the MCP 350īs are not able to be modded to 355īs anymore right!?
What a mess. Just bought a 350 to mod it later. Well okay, so I donīt need to screw down the speed anymore :D
It was just for fun, to power up, if wanted. Most of the time my Pumps ran at 70%.
Just to put my 2 cents in better later than later, I ordered an MCP 350 from performance PC hoping for a solder mod and I have exactly the same version as burninator. Same pcb, so no mod for me. 3800rpm according to my motherboard and the pure blue impeller. Ahh well c'est la vie as they say in Finland ;-)
I guess I'll have to stick with the mcp-350 unless Honda wants to work out something with me too..... :)
...Damn, same here i got the MCP 350 like the OP did, and its just to bad it can't be modded. well, time to buy another 350 and run them together with a dual top.
