One idea I had was to just ditch the clutch fan and put a nice big electric in there with a variable ramp up speed. Clearly the clutch fan isn’t doing the job

Your best bet is to buy a brand new BEHR fan clutch. Been there done that.
You can also put in an electric fan with an adjustable probe switch that slots into your radiator. Of course switch the fan with a relay.
The reason why a radiator probe is better than a cylinder head sensor is because your engine/transmission will run cooler (with a cylinder head switch your cut in temp has to be higher that the thermostat temp. otherwise the fan will run all the time)
Running your car at 110 will damage your head gasket (already a weak point on M104), wear out your transmission sooner, wear out your rubber/plastic parts on the engine and cause leaks.
