This will
not check fan operation for overheating situations, to do so:
Once car is at normal operating temp, sit at a stop with car in drive,foot on brake and load alternator by having headlights and rear defrost on, a/c off. Cooling fans for rad should come on with temp increasing by about one letter on gauge and then go off when temp drops to almost the normal position.
BTW if your car ran at the R/M position before there is no reason for it to run lower now, remember purpose of thermostat is to keep coolant temp at or above a minimum temp (some tolerance differences between each one of course). When coolant temp rises above fully open thermostat setting (216 F) then it is up to other parts of system (rad and fans) to prevent over-temp.
