Looking for correct Thermister of my WOrkbench. Any thoughts?

I noticed you posted this twice in another thread, please just keep this to one thread to make it easily reference-able and so there aren't two separate conversations about the same thing.

I don't know what the thermistor or hotend on the workbench are, but if you're having hotend issues I'd definitely recommend upgrading to an e3d v6 or a lite6. There are some mounts available on thingiverse already, and I'm sure someone around here can help with the firmware changes also, if you decide to go this route.
