I have the same problem as you can see from the pictures.
I noticed , just as you that the light on the block is not completely lit up. I checked through the BIOS that the pump rmp moves at the 2700-2800 range, which is the normal value that Enermax stating as well.
After digging around i found out that there seems to be a "fix" for that, or more like a "maintenance" thing.
