Loop flow back pressure won’t release

Hi,
If you have the d5 pump pwm wiring connected to the mother board or really anything disconnect it system via 24 pin cable is not connected to the board.
24 pin cable you're not using the jumper to fake the psu out to run the molex or sata power to the pump so how is the pump powered ?

How long the piping is does not matter it's just more fluid.

thanks. The pumps connected to the fan headset on the Corsair commander pro. I’ve got some fan to molex adapters so I’m gonna try use one of those to make sure it’s getting the full 12v. I’m using the jumper method just took it out before taking that pic. Didn’t want to risk powering the board and glad I didn’t because I’ve already had a few spills everywhere.

Hi,
Connect the molex for the d5 pump directly to the psu cable not through a controller.
 
You are not suspost to use teflon tape on those fittings if they are right and half way decent finger tight should be leak proof
if its not something is wrong, you didn't get a piece of tape sucked into the pump did you

Or rad.
 
Hi,
Didn't use ek fitting wonder who's they are and soft tubing too ?

Thought you might have outlet oposite but at least one image says outlet is on the left.

but the Corsair one still has either a partial block, and it’s only partial as I can manually hack out a lung and blow past it, or a air lock still.
if you really have to blow hard to get air to flow thru this radiator, there is something wrong with it. There should no restriction at all.
 
Thanks for the help everyone. Finally figured out what it was I had both the fan and molex connectors connected so it was only running on one. I’m assuming it defaults to the fan connector if you have both connected. As soon as I removed that it kicked into high gear and the loops semi sorted now. Just gotta bleed and fill now still a lot of air bubbles.. 10 months to build one pc, that’s gotta be a record!

nice sometimes you just figure it out, and think how come i missed that stuff before

Hi,
Usually software adjustment controllers only work when the computer is active so leak testing not a good time to use one.

Yeah it’s always the simple things. I didn’t think to check what connectors it used and if both need to be connected. Need to learn to be more open to everything I’ve got a bad habit of ruling things out because there unlikely or nah that shouldn’t effect it.

isn't that how it controls the pump speed? You adjust it via that fan header power comes from the molex.

The pump/fan header is only for PWM control and rpm. The pump gets power from the molex. And w/o a PWM signal the pump will run at max speed so unless you were running a PWM profile with the motherboard powered, you were using the pump at max speed. In any case even if it were a non-PWM pump, it would still be running at max speed or whatever speed setting if it was a vario.
