Also does it happen if you only plug in one loop. The more I look at it, I'm with IRA in thinking maybe something with the power. Maybe switch the power over to one of the other rails if your PSU has multiple rails.

With the fluid flow, I don't think it's air like I was thinking. I'd keep looking at the power.

There is always a chance you could get one bad pump, but two is almost unheard of....got to be a power issue.

Maybe the particular 12V rail is fine while cool and throttling as it warms up. The D5's do have some circuitry in them that protects them from overvolting and will throttle themselves. I noticed this in my testing where I would be at 13.0V and peak flow rate, and as I quickly turned up voltage the pump would first respond by speeding up, but then it would adjust and slow back down to the same speed at 13.0V.

Anyhow great work on getting after the issue, you'll get it..just keep it up!!

# Martinm I didnt test it before but i just got home and before answer anything here I test it out... the voltage was the same... this time a mv less... 12.05 I guess.

If so, it could be something to do with the 12 volt rails out there ... as Martin pointed out.
I see that the fans are also connected to that supply via a SunBeam rheostat.
There may be too much draw on that particular supply rail with the rheobus pulling for all of the fans. You may want to try the pumps without the rheobus plugged in.
Also, how do you have the power supply rigged for turning it on and off ?

For my own external power supply, I needed to put in a 10ohm 25watt wire-wound resistor across the 5volt rail so that it would keep the supply from spiking and/or surging on the 12volt rail. It's a known issue with some switching power supplies.

# hey crazyjoe, most of the time that im testing it, im only running one pump at a time, if the problem doesnt occur then i add the second one to the testing, but each of then is connect to separated railings. Now for the psu to get on and off... i got one of those military switch which u may see almost on top of the rads between each one, on one of those pictures.... i did test the psu with the pump on it for 2 minutes and at all the time it was above the 12v scale... now the reason for the 2 minutes, because this pump started kicking right from the beginning so I was afraid to let it kick for a long period of time....

I'd just put some straight distilled in it for now and see what it does..Just to see if the coolant is part of the problem, the stuff looked like syrup to me...

Leave your t-line in for now if its that hard to change out...Use distilled and see if it still does it, then we can go from there..We need to eliminate one thing at a time.....

I like to mix this at 10 or 11 -1 with distilled..Pentosin..Then a couple of drops of this for a biocide..PT Nuke..Then a ounce of glycerin for a water wetter and a drop or two of blue "Dawn" dish-washing soap, its a surfactant or water wetter also...You don't want to use to much of either one of those or it will hurt temp's....If you have a VW or Audi dealership near you, you can get Pentosin cheap there, its just anti-freeze, the blue is G11 and the red is G12.....

EDIT: There right about having it under load when you metered the molex, you did have it running then didn't you?

# hey ira im going to run some distilled water right now, now another thing that i was thinking can i run some tap water on the pumps? for like maybe 10 minutes? what im thinking, to eliminate the problems with the pump and power, will be have me run then out of my loop and see what happens....

# Hey tony, sorry didnt mean to disrespectyou or not that your advice at any point man, its just that at the sametime this could be the problem, but then how come the green is doing just fine... if I didnt have the green coolant here this would be one of the first thing I have done, but the green is basically water and i got the same problem on that too...
thanks for the help...

You just have to rule out one thing at a time with a new guy...Its hard to trouble shoot long distance...Things I would do with-out thinking about you have to remember to tell them...Thats why I encourage all the new guys to get in here and help each other out, its a learning process and the things the more veteran WC'ers take for granted or don't even think of anymore a newer guy will remember to share it......

hey thanks for that will probably place an order on those too... =]


-------------------

Now like I said before can i run the pumps each separated on tap water? this way if its not the loop, not the coolant just gives me psu and pumps right? if its not then....

another thing i dont know if that could cause one of the problem... as the green coolant is to thin, and when i run it without problems I got a extreme flow that shoot too much water into my bay reservoir, what happens is if there is any air into the reservoir it gives me bubbles on my whole loop... example: its almost full but air is in it... so water cames extreme fast, makes bubbles and comes out fast and bubbles goes with it...

that wasnt too bad after i got it 97% full (estimate) after turning shaking my case a bit....

but im thinking about getting a double res, maybe that will help... where fiiting will be lower and air will be higher...

what you guys think?


thanks for the comments....

Sure, Just rinse it out with some distilled afterwards and it should be fine..You'll get it going Made...

ok here is the plan...












we couldnt keep up the water in the baby thing there for the 10 minutes run so we are getting water from different locations to see that... but it ran good for the time it run....

Hey that looks like fun.....At least you know the pump is good....Thats how I flow test my loop, with all the components hooked to the pump, you just run it though into another bucket thats marked at gallons then time it for 1 minute and you will know your loop flow....

If your pumps are good I would try it with just distilled in it and see what it does...Then if that doesn't fix it I guess we need to look at the power again, or go ahead and yank out the t-line...Heck I don't know..I know you will get it going though, I'm sure of that.......Thanks for the pic's....

lol thanks for the support and keep me motivated =]

EDIT: here's what I wanted to post before and i forgot...

I want to post all the different problems with each one pump and solution and whatever we got so far that i can remember....

So here it goes ill # the pumps... if take a look back at the picture inside my computer, and the other one where the pumps show on the outside, you guys might now which one im talking about...

Starting from inside from the left to the right:

Pump #1 - inside the computer, hook up to the blue coolant which was ticker, 1st pump you can see when looking at the picture, water coming from?: Big reservoir at the top of the case, water going to?: T line"before" - now direct to the pump.

1: More like a air problem, but at the very beginning I had a problem where it start to suck water from the res, and started to suck air instead of water (air did not reach the pump) pump use to cut like all other... method to resolve it: filled the res with more coolant and it stopped.

2. does not give me no more problem after the first one, runs fine from the very beginning for the whole time it was running.

Pump #2 - inside the computer, hook up to the green coolant thinner like normal water, pump behind 1st pump inside the case, water coming from?: bay res, going to?: t line didnt took the T like out yet...

1. Sucks air from the res when both pumps on the same loop are on, if the res is not all the way full it makes bubbles and goes into it.

2. cuts speeds, runs fine for the first 2 minutes then start to cut. same thing happens when one pump or both are on...

3. when it cuts if I disconnect it and connect back again runs for another 2 minutes...

4. Youtube video its about this pump, it was just this pump connected at the time

5. didnt had chance yet to change speed.. its set to 5 right now.

Pump #3 - outside the computer case, green loop, coming from?: t-line, going to: rad.

1. that problem only happened once with this pump, its runs good so far now.

Pump #4 - outside the computer case, blue loop, coming from: used to be the "t line" now from pump #1.

1. this pump its actually the pump if first noticed the problem... it cuts right from the beginning.

2. when turn on it starts cutting, turning it to a lower speed, keeps it running and after few minutes i can set to the maximum speed and runs fine... by turning it off and on right the way (short period) it keeps working, if let it rest for a longer period then same problem occurs... so i got change speed again... and start all over..

3. took this pump put and open it up and took some picture, and everything looks good...

4. tested it out with plain distilled water "pictures" for 6 minutes and ran without problems....


------------

so you guys see its a variable of facts thats making this damn thing happen lol... ill keep it post as i remember more of it.


yesterday i ran my computer for about half hour with pump: #1, #3 on at all the time... and also with pump #4 after doing the speed trick, and pump #2 for only 2 minutes as it started to happen again....

Ok Made...Have you tried those 2 pumps you just tested back in the old blue loop with just distilled water in it yet? If it does do the same thing do you have a spare PSU that you could jump and hook the pumps to? That will tell you quick if its some kind of power problem..
