Hello,

I just finished putting together my first watercooled build but I am running into an issue with my D5 Next Pump. Upon turning on my PSU the water was able to cycle through my loop; however, it appears as though my pump fan is not working at all.

Note: I assembled the system and filled it with water once before (just to flush it with Blitz's part 2 solution) and everything was working as usual. However, upon assembly/filling a second time it seems I may have caused the pump fan to no longer work.

I'm hooked up to the OCTO controller and I know it's not an issue with a loose molex cable as all my fans are also wired to this controller and turn on when I turn the PSU power on. What could I have done to cause this? Has anyone else experienced this issue with the RPM on the D5 Next Pump not registering? Is there a way I may be able to fix this? Any help would be appreciated thanks!
