Already tried and tested Ryzbor, really no need to ask then. The removal of the onboard NTC resistors is discussed in the Convoy 17/22 mm SST40 Driver temperature protection removal thread, and looks like someone found it in the XHP70x driver.
In my experience, though, you can place your multimeter's probes over the resistor pins, and blow some air with your mouth while looking at the multimeter's screen. Even if subtle, that will reduce the resistance 1 - 2% and will give you confirmation that you are peeking at the right thing.
