That would be my guess too. I think OP really needs to give links..

Depending on how old the systems in use are, that may make sense as the GPU used to be built into the system chipset (or northbridge on even older systems) rather than the CPU. Again, please give specific links if you really think they are seeing a temp from a GPU integrated into the CPU

Yes, the OP scanned the PCI bus, but because this is a Skylake (Sunrise Point chipset) system, sensors-detect isn't quite up-to-date enough to handle it completely:
Found unknown SMBus adapter 8086:a123 at 0000:00:1f.4.
Adding this block of code to the PCI definitions section of /usr/sbin/sensors-detect would probably allow it to scan the bus (though I have no idea whether that would result in additional output from sensors command).
}, {
                vendid  => 0x8086,
                devid   => 0xA123,
                procid  => "Intel Sunrise Point (PCH)",
                driver  => "i2c-i801",
sensors-detect also gave this error, but googling didn't give me any clues as to what kind of sensor it is:
Trying family `SMSC'... Yes
Found unknown chip with ID 0x1d00
