what cable do i need to power on pump? - Page 2

Well my mobo is a G1 Sniper M5... I guess I better get out my soldering iron and pliers! Do I need a molex tool? I bought 125ft of sleeve for my psu but don't want to pay for a tool.

You do not need a molex tool or a soldering iron (unless you prefer to use that for heatshrink instead of a lighter or heat gun).

I use the thick part of the soldering iron (not the tip) to shrink my shrink wrap... but otherwise just use a lighter (never use a lighter) LOL. Heatgun or soldering iron one or the other lighter can leave carbon stains or burn stains or just flat out melt stuff.

Molex tool is for removing pins... Typically you would need a special crimper but seriously. You don't need one unless you are doing it over and over and over then yeh you need one.

The trickiest part is crimping those fan connector pins... which you can do just fine with a pair of needle nose pliers but not that way you would think. I don't usually recommend that you re-use fan connector pins but if you are really careful you can re-use them. Only problem is careful or not the first time you pull one of those pins out... you are probably going to ruin it.

So be prepared... You don't technically have to remove the RPM wire pin because it is already terminated with the right connector... BUT!!! It makes sleeving it a lot harder... You can probably get the sleeving over the 3-pin but you would have to use some really good shrink wrap with a real high shrink ratio (or whatever it is called)... But it can be done.

So you will need a few molex pins, a molex plug and if you plan on removing the RPM wire from the fan connector then you need to have a few fan connector pins on hand... Both are dirt cheap though. If you are going to remove the RPM wire then I would recommend you buy a new fan connector plug of whatever color you want to raise the bling factor. White and beige are not that nice looking especially after sleeving.

Also this will be good practice but not good enough practice for sleeving your PSU... If you can't remove a pin from a 3-pin fan plug... you will never get the tons and tons of PCIe pins out of the motherboard connector and all your graphics card plugs. Not that they come out in even remotely the same way just they are infinitely more difficult to remove the first couple times you do it.

Okay.... sounds fun.... I hope I don't screw it up...

Post a tally of the parts you have that you need to do this so I can double check it.

Please refer to a picture chart showing where the + and - goes in the molex plug... BUT the bottom line is this... + is always on the outside and - is always on the inside next to its matching + So what that means is that if you accidentily get it mixed up all that will happen is you will be supply the pump with 5v which wont ruin it. It will just not start or it will go slower starting voltage say 8v... if that is true then it just wont start. I know my DDC pumps will start at 5v usually and they always start with 7v so I don't know what will happen if you ran 5v to it. But it wouldn't ruin it.

That said besides the simple fact that if your positive is on the outside you are safe if you look at the bottom (the flatter side) 12v is on the right and 5v is on the left. That is with the cables facing back towards you not away from you which is why you need to look at a picture diagram so you don't mess up... BUT if you mess up nothing is going to get broken. But if it does get broken it isn't my fault smile.gif

Are you saying easier than re-terminating them or easier than using an adapter... because I don't see that as being easier than an adapter...

Also you should not just cut the wires off the 3-pin if you are going to use the 3-pin... especially since you can just use a tiny flat head to pull them out... Cutting them could lead to the + and - touching each other at some point... unless you individually tape off or shrink wrap them which at that point... using a flathead screw driver to remove the pins is a whole heck of a lot easier.

Just saying.

and gigidi gigidi

When I mean cut them I mean pull them out of the connector first, except the RPM wire. Cut the pins off, then solder them to a Molex, personally I would also sleeve it. Should really have to say that you need to remove the pins first...pretty logical lol.

Well yes because he hasn't done it before and may not understand the danger of cutting the wires off not matter how close it is to the connect there is a risk of short later on. If I told a friend that had not done this before to just cut +/- off fan plug and then solder them to a molex we would cut them off with snips and then solder them to the molex... thing that since it isn't like wire is haning out of the plug it is all good... only it isn't because something metal could brush up against those cut wires.

I usually read directions to be directions and am careful not to make mistakes by simplifying words or sentences or idea just because I think someone else may get it because I get it.

So if that was your original point (to remove the pins from the plug then cut the pins off) then sorry I misunderstood that... nothing wrong with clarifying though. You def don't want to cut first and pull pins later because you need to be able to grab on the wire to move the pin around a bit. Also I don't know why you keep talking about solder. Unless you mean to take an already made and terminated molex adapter or extension and cut the wires strip them and then pair the 2 together... If he had an adapter we wouldn't be trying this if he has an extension or splitter sure he could hack it up. Or he could just order the pins he needs to do it the right way which doesn't use a soldering iron.

Cause soldering is faster, easier and cheaper than ordering new pins and a tool to crimp them. He could easily solder the wires to any molex extension, most gpus come with a molex to 6pin pcie, even that would work.
