Help solve Pump issue

post #1 of 21
Thread Starter 
I am having trouble testing my pump that is new. This is the first time I have filled it with coolant and it appears like in the image below but with all the tubes and such connected. At this stage, only the pump is connected to an external power supply, NOT the main system as it should be at this point. The only thing I have done to the pump is added a Bitspower "Mod Kit", which required removing the molex pins and putting them back. I followed direction and made sure the wires were in the same 2 slots they were before removal (there is only two a red and black).

The problem is I get no power at all from the pump and I can't hear it running. My external power supply seems to turn on and it's fan does run. However, I noticed the fan was not very loud or spinning very fast, which it may not if no other loads are attached, it's just an old power supply being used to prime the pump. The pump molex connecter is attached to an SATA to Molex connector which is attached to the power supply SATA power cord. I also tried just the Molex and same thing, no power.

At this point I am not sure what is going on or if there is any power going through that power cable on the power supply. If there is, I do not know why the pump is not working. I don't want to have to drain the new loop and take it apart unless absolutely sure the pump is dead.

If anyone has some thoughts that has used an external power supply to fill their res and power the pump let me know what you think may be going on. Not sure what else to try, but I need to know at least if there is full power going to the cable to power the pump before looking at the pump itself.

Thanks for any help.

Are you using a jumper on the proper pins on the 24 pin to actually get it to work (IIRC it is black and green? I actually just bought one that has to be depressed to work, release and it cuts the power)? That is generally what is done to test pumps/fans etc. You can search for videos and guides if you are not doing this and need help with figuring it out.

No, I am using a custom cable from Performance PCs that has as 24 pin connector on one end and a power toggle switch button on the other. It's not cutting off, the fan is always running on the power supply, just at very low speed. Not sure if that is because there is no big load to make it run faster or not. The power cable that is on the power supply should be powering the pump unless:

1. The pump is not working at all.

2. The power supply is not outputting power to that cable for some reason.

3. The red and black connector pins are not in the right order on the molex plug for the pump (even though that is how it came).

4. Other?

Here is something to check, but not really sure what it means?

Did you do any work on that pump?

I did some work on mine and forgot that the 12v red wire (on pump) needs to be hooked up to the 12v yellow wire on the PSU molex. LOL
Here i was trying to run red wire (on pump) on red (on PSU) and forgot that the red wire on PSU was only 5v.

As I mentioned, there is a long cable running from the pump with these two molex pins, one red and one black. I am not sure what they mean by the above since I only have those two wires and they have a molex connector on it. It will only plug in one way and I have no other wire to hook to a yellow. Can someone that has tested their Swiftech 655 pump with an external PSU let me know? Everything else seems to work fine, but no power going to the pump. The above may be the answer or else it's simply defective, just haven't ruled out the other possibles yet.

The pump won't make any noise til it has water running through it. When you fill the reservoir does water come out of the pump output?

Its possible you have an airlock in the pump itself but if you put your ear right on it when you turn it on and it makes no noise at all after a couple of seconds then its probably not running.

I would unscrew the pump from the top and connect it to power and flip it on and off real quick. If the impeller does not turn you have another problem with the wiring or power supply.

The poster above means the red wire on the pump will not line up with the red wire on the PSU molex connection. As he said that is the 5 volt line on the PSU molex plug.

Your pump plug should look like this ... the pins on the right side as you look at it with the chamfered corners on top.

Thanks for the info. Yes, when I filled the res top, the coolant did come out of both the "out" and "in" ports on the side as shown in the photo above. The top is about 70% full and the main in and out tubes are about half full as well with no blockage at all impeding the flows that I can tell.

Update:

The issue was the molex connector on the pump. When I checked, the plug was fitting the power supply cable, but it was going red to red and from what was said it should be red cable on pump to yellow cable on power supply. This gave the pump power, but it is sill very quiet and seems to come and go. When I turn it on now, I do get movement of the flow and the tank top starts to drain. But then for some reason it seems to just stop and the coolant then runs backward through the loop and into the pump top res. In other words, nothing is pushing it through the tubes and it hasn't yet been fully filled.

Is this lack of power maybe still from the power cable on the PSU or Pump? I am not sure what is going on as there are times when I switch it on it will seem to really work like it should and flow, then just stop with no power or something? At this point, I don't think it's the pump itself since it will power briefly, though I could be wrong.

5V is not enough to power a D5

You haven't made it clear if you have actually fixed the problem.

If you have is there a way for air to escape from the loop? Is the top of the res off or a port open so that the air that is being displaced by the water you are pumping in has somewhere to go? I saw a guy destroy a pump on youtube because he didn't do that.

Yes, it is not on the 5V anymore as stated above. I did have an issue with it being reverse where the red from the pump was going to the red on the PSU cable and it should've been the yellow on the PSU. This is what worked and there seems to be power going to it for just a few seconds then quits. I do not hear the pump or feel any vibrations from it at all at any time though.

I know there have been issues with the Koolace pump top mod before, but mine is Bitspower. Also spoke with tech at FrozenCPU and they said they have had no issues with any of these parts working together and do so quite often, especially the Bitspower mods. I was told to try it outside the case with a small closed loop connecting the in and out ports on the pump top mod and filling with just DI water in the res tube. It should run that way, if not take apart and see if the pump is locked or if it has any motion at all, an O ring or something may have an issue or some air may be trapped in the pump itself.

The top of the res tube is on, but there is no fitting on it (see photo above, but remove the fitting at the top) so it is open at the top.

It is a 655-B model and they said maybe it got stuck in a low power mode or one of the settings is not working and to try changing it to something else and back again.

Otherwise, not sure what else to try. I had to totally drain the res and some of the loops which took awhile, so I am going to test it outside the case just to see if anything powers. If so, then it's not the pump, otherwise, I'm pretty sure it is.

Also, someone said that some PSUs don't run full power unless there is a load. This may be what is happening with my Enermax 500 watt PSU, I don't know about this either. If so, that would make sense because sometimes I get power when I first turn it on, then it quits after about 5-10 seconds like either no power or very little.

Ok, well that is very strange. You will need to dismantle the pump and check the state of the impeller. It should turn freely by hand.
