Installing the modifier PCB looks like way too much work for my lazy ***.

It would be good to know if those pumps are a good bargain.
So don't forget to share your exp. here

with this new pcb, is it still possible to mod the 3.1s to 3.2s via the solder mod? Ｉ wanna buy like 4 of these pumps because it's such a good deal!
If I understand things correctly, you don't mod this like the 3.1/3.2 mod, it works of straight voltage control.

so since 3.1=3.2 other than solder difference, with this new pcb, there's no performance difference between 3.1 and 3.2?
There is no 3.1 or 3.2 (or 3.25 or MCP35x for that matter) with this repair kit. How much voltage you use is how fast it runs.

So, you will need to solder the items to the board first before putting the PCB into a DDC pump? Then, solder 8 copper tiny lead-wires of the pump armature to the new PCB?
It sounds like a job for really tiny fingers and a professional hobbyist soldering station.
But the thrill to have an all out DDC with no limits and a POT (variable resistor) is very intriguing. I have several dozen DDC-1T (MCP350) pumps on hand but no pro solder station.

The pump Maverick, BMaverick... has a massive hoard of a Laing DDC pump stash
I've been using a heat gun (used to strip paint) to reflow-solder dozens of LEDs onto various types of PCBs. Works like a charm. If you happen to have a thermocouple sensor as well, you can even regulate the temperature by raising the whole thing up and down over time (and thus follow proper reflow preheat, solder and cooldown times and rates).Very interesting... but I hate small surface mount components.... but it looks so interesting.... but I hate surface mount..... but...but... Gwaargh!!! CONFLICT!!!
Hm, wait a second... I'm sure I could mod my toaster oven to serve as a crude reflow oven.
I think I'll pick one up to play with.

according to you right?
The one is POST-REPAIR PCB mod.
The other is PRE-REPAIR PCB mod.
So no, they are not the same. Why the attitude?

sorry, Ｉ didn't mean any attitude. I'm really confused lol
I do believe Boogerman is right. Neither of those pumps are using the PCB that diyinhk has for sale on eBay. If you do this modification to both of those pumps, then yes they would be exactly the same.
Neither of those are using the repair PCB kit. They are regular DDC's with the special liquid compensator housing. What you asked about was the repair kit being modable like the old 3.1 to 3.2 hack.

Can't really say but it does look like they are the right models for the mod.

The pumps he is selling do not come w/ the modified PCB that he also sells. He sells DDC3.1's and DDC3.2's. The only real difference is the PCB on them. So if you were to throw in the modified PCB's in them. Then they would be pretty much the same pump.Now I'm confused.
He is using another PCB on the MCP350 But not the blue one.
Also the MCP350 is not a 3.1 but it has a black impeller, so its a 2.
The PCB is replaced by the famous Japanese SANYO motor driver. It has built in overheat, motor lock and even water leak protection. It's much more advance, reliable and silent than the original. Moreover, it use 2oz copper thickness PCB and Teflon wire for the power cable. It also has the TACH/RPM wire(blue wire in pics). We have confidence and our custom PCB is provided with 1 year warranty
The seller also told me this
The 12W DDC use our new Sanyo motor driver PCB, it's not on sale in ebay yet. It's running at 3600rpm, the same speed as a MCP350. The 12W is black impeller. There are test in the internet that black impeller has bigger center hole than the latest blue impeller, and the performace is better.
And the MCP355 is 3.2, without any modifications on the PCB.

Most definite is that someone has to buy each of those three parts and fully examine what are they capable of.

zenix: you could also ask him if he can make PCB or premoded pump to be regulateable via PWM / MCP-35X alike, and consider selling presoldered kits, even if at higher price.
guys keep note, that our current tops were designed with the pumps which we use right now.
Not ddc's with volume compensator.
Last thing to note, not all tops are M4 threaded.
These ddc's with larger base housing will require your screws to fit in stock housing or your gonna have one hell of a time at a hardware store looking for the proper bolts.
Also another thing that scares me is that the FAKE Laings had larger bases...
and to my last knowledge, it wasnt the black impeller DDC-1 which were the best, it was the RED Impeller 18W DDC-2:

Interesting to know that the ebay ad states,
"...This is the rare special edition Laing DDC1A-VC with built in liquid volume compensator. It is the famous black rotor version with bigger center inlet hole. These pumps were originally pulled from working Mac G5 liquid cooling assemblies. The liquid volume compensator is a deluxe feature of Laing DDC water pump for OEM order only and it is not available for sell in the retail market until now. ..." http://cgi.ebay.com/Laing-DDC-water-...item35af2f581c
The DDC1A-VC 12W for the Apple G5 workstation used a corrosive salt based coolant. Since these were pulls from actual G5 machines, I would not even dare get involved with those pumps. There are reports all over several of the Apple forums about this coolant leaking and ruining hardware.
Now, when the Dell H2C 720 gaming rig came out, Dell did not want the to replay warranty issues Apple had with those VC pumps. Instead, they went with a distilled water and propylene glycol mixture with a custom corrosion inhibitor package.

The pump Maverick, BMaverick
salt based coolant? why for? what advantages it might bring?(except of course corrosive disadvantages)
Probably 0.01C and 'low costs'.
“Little expense had been spared to create the impression that no expense had been spared.” - Hitchhiker's GuideMondays:It's better to ask dumb questions now, than to look stupid later
So these should not be bought?
Also what do all the extra things do...like the liquid compensator and stuff.
