Thermometers reading different temperatures on cold printer? (lemmy.world)

I am in the process of buttoning up a Nitehawk conversion on my Voron. I also replaced my extruder thermistor with an OE replacement purchased from a reputable vendor.

Post setup, my heated bed is reading spot on (it's 18.3 C in my basement aka 65 F). I verified that my extruder is also at ambient temperature by wedging a Thermapen under its silicone sock and letting it acclimate for 10 minutes. The I'm not sure why the extruder would be reading high.

I bought a spare thermistor and wired it in. The result was identical.

Thoughts? Ideas? I'm pretty sure I have the Nitehawk and thermistor set up correctly.

It's the same thermistor value that I was using previously, but I did replace the thermistor when I installed the NH. This means I'm guilty of changing two things at once, which makes attributing cause hard.

I ran my first prints after the NH install yesterday and all went well, so I'm going to file this in an OCD annoyance vs something I need to worry about.
