I tested it on my XPS13 9333, here what sensors outputs:

acpitz-virtual-0
Adapter: Virtual device
temp1: +27.8°C (crit = +105.0°C)
temp2: +29.8°C (crit = +105.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +62.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +62.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +61.0°C (high = +100.0°C, crit = +100.0°C)

i8k-virtual-0
Adapter: Virtual device
fan2: 0 RPM
CPU: +62.0°C
Ambient: +49.0°C
SODIMM: +46.0°C
temp4: N/A

CPU seems to be correct, but I can't say anything on Ambient and SODIMM.
temp4 is constantly equal to SODIMM without this patch, so I'd say N/A
is correct.
