One thing I noticed is there is a slight difference in readings between the flat and bulb type sensors. With all the sensors bundled together outside the case in ambient room air, each type of sensor reads within tenths of one another. Not a big deal but just an observation I made. As far as response, nothing more elaborate than putting a sensor between my fingertips and watching the temp. It started to climb immediately, peaking out within a few seconds.
All connectors are removable off the circuit board allowing ease of install and wire routing.
The board is numbered for fan and temp sensor location. All fan plugs are numbered at the fan connector end but not at the board connector. The temp sensors have no number on either end. As you plan your install you may want to number the sensors and the fan plug board connectors so you can orient them to the proper points on the board during final assembly. The Digital Doc5 is of sturdy construction with a U shaped metal frame the components attach to.
