Fan sensor

I've read about changing the KZ sensor with a ZN sensor to activate the fan earlier, and that's what I'm intending on doing.
But now, deciding on the purchase, I am confused with making sure it's the right one.

Mine, KZ, has 97 and 120 stamped on it. So, one with 97/110 stamped on it is the correct one kicking in the fan at 110 instead 120 - 10 degrees lower? Is this correct, and is this what I should be getting?

ON at 110c/(230F) and OFF at 97c/(206F)

Some are 3/8" MPT. There's LOTS of material in the therm-housing to drill and tap to this next size if required.

(PITA not being able to copy a link addresss for ebay)

That's all I need
Thank you!
