It might be helpful if you mentioned the specific cooler
model and linked to manufacturers product page or a good
review providing more detail about it.

Not knowing exactly how it's set up, one option might be to
carefully bore a hole into the side of the 'sink (metal
base) just barely big enough for the sensor, taking care to
deburr the hole and finish it well so it wouldn't have much
of a chance to short out the sensor leads, then fill in the
hole with thermal compound and plug it, or permanent
installation with thermal epoxy- so there is far better
thermal conductivity to the sensor from the metal.

I would not try to wire a sensor between CPU socket and CPU,
perhaps what they had meant was to put it wedged inbetween
the bottom of the 'sink and the CPU carrier (just beyond the
heat-spreader).
