    Looks like the fan entries are being commanded pretty much full out..
    (I'm sure those don't all correspond to physical fans, but likely
    different fan speeds.) Are you sure there's not a hardware problem (one
    or more fans not working, vents/heatsink clogged with dust)? Your system
    seems to be running very hot.
