PSU fan speed monitor

[rrrrrichard]

Are there any modern, modular, top-class PSUs (e.g., Seasonic X750, Corsair Pro Gold) that have fan speed sensor connectors that can plug into a suitably equipped motherboard?

I know that the PSUs that I'm considering have built-in, clever fan speed controllers. I don't want to override these things. I just want to know that the fan is spinning (or not).

Thanks!

you can use custom one but you cant measure temperature so what is the point
btw stock fan is like 5$
if you just wanna know if its spinning or not put a led before the fan(you have to open psu and weld it not that hard but at least you have to know how diodes work)

HWMonitor can monitor voltages and fan speeds and its free.
