Aye but requirement for this feature is minimal from the end-user in this particularly scene... most just want a simple pulse that the bios can recognise as fan working or not working (pump working or not working). If not working, switch PC off. IE: if pump fails and doesn't send more than 2200rpm signal (most mobos tend to whine at 2200 or below depending on manufacturer) then doesn't let PC boot, or if occurs during use and rpm drops below threshold, PC switches off.
That's what most people want an RPM feature on a pump for. VERY few ppl want to slow a pump down, especially one that's silent to start with... economics wise, the power saving is also minimal when you're talking the kind of consumption these particular pumps take...
Very few folks in this scene use "standby"... it's PC on with screensaver, or PC off... PowerSaving features are put into play by enduser purely for noise based issues - slowing fans, but if pump is silent to start with (which the mag is) then it doesn't need slowing. Most go to watercooling so they can leave it running 24/7 downloading pirate crap tbh without it keeping em awake at night, or leave it folding 24/7, so standby isn't an option for them... and that covers a big chunk of the market...
RPM builtin to pump is far more convenient than flow indicator/meter. Most end-users only want a flowmeter to get an RPM to use the bios emergency shutdown feature, not to measure actual waterflow or control pump speed...
