You still have the pressure drop caused by all of the components in the loop.
While the D5 on setting 1 would move some water, the flow rate through all of that would be very low.

You can still have flow without spinning that impeller.
The velocity of the water going past the impeller may not be high enough to make it spin. I'm guessing the sensing part of the flow meter uses a magnet, so there is a minimum velocity that would be needed to get the impeller moving.

Try turning the pump down while watching your temperatures. If there is absolutely no flow, the CPU core temperatures will spike up very quickly to the temperature where the CPU starts throttling.
If you still have some flow, even just a trickle, the temperature rise will be much slower, and may stabilize at a point before the CPU starts throttling.

If you're temps are still reasonable you have flow...guaranteed.

Most flow meters have trouble reading lower flow rates.

If you remove the disconnects, then sure you will have no flow, but if there is actually no blockage, you will have flow if the impeller is turning.


If you don't have flow, it's only seconds before your CPU will peg Tjmax and start throttling itself. You can see what that's like in this indigo reflow video:

If you don't see that, then you have flow and your flow meter simply isn't sensitive enough to pick it up.
