That is up to you....
I was simply diagnosing your problem and making you and other readers aware of this possible...and also to explain the trade off of going to the extreme/lowest cut-in when bridging/changing the sensors value.
I use thermistor/sensor bridging with satisfactory results in high ambient conditions, but I find approx 100C C/I to be fine. Many guys simply use a cabin over-ride switch that they can activate fans as needed by simply bridging the low fan circuit manually..[they bridge the high pressure sw at the drier]. This give low fan for traffic and towing conditions w/o too much fan speed and alt. draw.
...so, Cool Harness is cool...but it can be too cool in the sense that the lowest cut-in does not always equate to the best application when all aspects are considered. Which is why JF has different R values to chose from.
If you find it to be a problem, I would simply change the R value to a higher cut-in for fan rather than eliminate the Bridging.
