EAF temperature sensor placement?

[dk101]

I was wondering - where do you prefer to place your EAF temperature probe for maximum effect?
I was thinking of (somehow) attaching it to the back of the primary mirror on my newt but i was wondering what everyone else does.

i googled this and while there is a lot of debate out there about the general usefulness (or not) of temperature probes there isn't much about "best" placement.

Thank you!

I've not placed mine yet, but, my first thought was to attach to the focuser itself.

As it is meant to measure changes in the tube I connect mine to the OTA with an elastic band or cable tie. To be honest I don't really use it as I refocus on increases in FWHM.
