If you're serious about using the temp probe as a cutoff, it needs to be set lower since for NiMh, some of these probes seem to lag way behind pack temp. The prob is the probe making contact with the pack - if this is a curved probe that will lie flat on the curve of the cell put it on cell nearest to the batt connections - thats at least better than the stick kind of probe that just sits there with marginal contact with the cells.

I would try 110F (or lower) and watch the next charge. If it terminates on temp, then bump it up a little. If this temp probe is like the stick style one I had with my Ice or TC1030 charger, its slow to react and reads way low compared to an IR temp gun. If you set it at temp pack should reach, it'll let pack opverheat before it cuts off.

I personally wouldn't invest in one if its the stick type. I don't know which style they sell for this charger.
