I'm running into a strange issue with my d5 (Amazon product)
I set up the whole loop and the pump wouldn't spin so I took everything apart and now just have a contained loop on the distro plate.
I cleaned the pump out (lots of black gunk...makes me think possible return?) and it would start and stop. If I loosened the d5 bracket it would start and stop and if I kept tightening it the pump wouldn't spin at all.
Also having issues bleeding air out of the pump area of the distro.
And advice would be appreciated.
Not sure I can add much about the pump not spinning. When I was leak testing the loop, I realised that I hadn't tightened the D5 bracket properly as air was escaping and I could hear it. After that I tightened it a fair bit and the pump seems to be spinning just fine. I am using the Alphacool Eispumpe VPP755 - Single Edition V.3. Maybe don't tighten it as much if there are no leaks. I also know from previous research that different D5 pumps are fussy as the impeller might have minor variations causing problems with custom distros.
The air in the pump area was easy to remove by turning it off and moving the case around and then adding more fluid to the distro. Took a few attempts but got it sorted fairly quickly.
