Connect a 4 Pin Fan to Mainboard (for RPM)- Where to Find ..

I just built a new PC and I replaced the case fans with better ones, but I
got all 4 pin types, but now I want to monitor the RPM of one of the front
case fans. It is difficult to get to the fan, so I would prefer to get an
adapter to connect the fan to the mainboard, to monitor the RPM.
I have searched, and all I can find is a 4 pin to 3 pin w/o RPM wire.
Does anyone know of a 4 pin to 3 pin with RPM wire? (or a 4 pin to 4 pin
with addtl RPM wire, if it exists.)
Finding 3 pin to 4 pin adapters with RPM is easy, but of no use to me.

Thanks,
QZ

The 4 pins are +5, gnd, gnd, and +12. There is no RPM wire on it and you
can't 'adapt' signals that aren't there.

I am not sure he has what you want, but he might be able to help you
get it.
