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.
