ModMyToys 3-Pin Power Distribution PCB in the UK/EU?

[MrToad]

Hi beautiful people :)

Is it possible to get these in the UK/EU or the only way is to order from PPCs / FCPU?

Thanks for reading :)

EDIT: This is not specifically a watercooling affair, but it is related. Hope I don't rub the mods the wrong way for posting it in this forum :)

You can always solder one yourself from some breadboard PCB and bunch of connectors, if shipping from stateside is not an option. Just connect all pins except tachometer/rpm one (that should come only from one fan/connector)

Thought on that :) in fact I even looked into making a proper PCB through this company (http://www.pcbtrain.co.uk/schematic/pcbtrain-express/).

However I've been watercooling for too long. Now, like water, I tend to always follow the path with least resistance :p:

Yeah, you can call it laziness too ;)

Still, thanks for the suggestion :)

I myself bought bunch of connectors from ppc-s and black breadboard from ebay (search for "Double-sided Breadboard prototype PCB,1160 holes". #1(last pic) (http://www.xtremesystems.org/forums/showpost.php?p=4754105&postcount=49), #2(finished and mounted) (http://www.xtremesystems.org/forums/showpost.php?p=4759356&postcount=59))

Thanks again for the input. I'm gonna go down this road too :)

Cheaper and quicker than ordering from the other side of the pond :) (I can get the stripboard, connectors etc locally)

warning u guys

ive had one.. and had problems with it.

It seems the one i had gave resistance on the last 2 ports making them useless unless i didnt mix out the ports.

So test the units b4 u install them live.

Couldn't wait for the board Churchy linked to arrive or rely on an order from the US making it on time (really wanted to finish this part of the project this weekend) so I had to compromise ;)

There were no black PCBs available "locally" (or black right angle headers) which is a pity really...

Either way, my issue is that I have to power to 9 fans on my Mo-Ra3 9x140, and I wanted something tidy, simple and small... So, I made two PCBs, one feeds 5 fan, the other 4. This takes just 2 channels of the AE5 :)

I bought two of these ModMyToys 3-pin power distribution PCBs and neither one works right :mad:
I can connect fans to them but the fans don't spin at full speed.
I'm powering these with a 4pin to 3pin adapter off the PSU.
Did I just get unlucky or do all of these PCBs have this issue?

[DumpALump]

Probably from the increased resistance and increased amperage draw. What is the decrease in speed? What is the amperage draw of your fans?

You can try soldering some copper wiring on the bottom to help decrease resistance.

I measured the circuit in my home-made adaptors and I get same voltage in every channel (12.04V at source, 12.04V on the lowermost circuit, 12.04V in the uppermost circuit).

Measured at the fan circuit and results are consistent.

Pretty happy I made my own rather than buying the ModMyToys ones :)
