This is quite common: fans running below some software defined threshold
showing as zero. It's a while since I used PCProbe but IIRC, it does have
a setting for that threshold, which you might try lowering.

It depends on your ambient of course but assuming that's a "comfortable"
living space, the 40C seems a bit high for the chipset, especially if the
CPU is reading so low. With Cool 'n' Quiet, the CPU generally runs just
slightly above my chipset, say 34C vs. 32C but this is with MSI mbrds and
every mfr may have different calibrations, err bugs.
