I already had installed it. After even running sensors-detect again, I 
got this output (after replacing the nvidia driver by the nouveau one):

acpitz-virtual-0
Adapter: Virtual device
temp1:        +52.0°C  (crit = +120.0°C)

nouveau-pci-0100
Adapter: PCI adapter
GPU core:     +0.60 V
temp1:            N/A  (high = +95.0°C, hyst =  +3.0°C)
                        (crit = +105.0°C, hyst =  +5.0°C)
                        (emerg = +135.0°C, hyst =  +5.0°C)
power1:           N/A

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +53.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:         +53.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:         +48.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:         +51.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:         +49.0°C  (high = +84.0°C, crit = +100.0°C)

As my grafics card is of type NVE4/GK104M, I'd expect temperature data 
to be available - but it obviously isn't (fan control should be 
available ...). Probably I've misunderstodd sth.?
