1) system fan speed and cpu fan speed are separate
for RPM monitoring the system fan must be connected to the 3 pin fan connector on the mobo
this is however not possible since those fans arent available anymore
the ones which work are high end ones and can be very expensive
2) yes temperatures are quite normal
however an extra cabinet fan wherever u can place it will help ur temperatures go down
specially a side case fan if u can mount one
mine went from 60 degrees to 53 degrees
