No, because the switch is in the wrong place.

Howver you need to establish if your switch is normally open and closes at it's hot temp or the other way around. As it will make a difference on the wiring.

Put the switch here, so you are using it to energise the low current coil in the relay, and the relay contacts handle the high curent requiement from the fan.

whilst we are on the subject... does anyone have a diagram for the same thing but with a fan override switch, so you can turn the fan on and off from the dash, without needing the temp to get high enough?

its my understanding that the switch closes when reaching 95 degrees and subsequently supplies the fan with 12 volts

Is how I had mine

Just add a switch a cross the temp switch for over ride

Or if you have a 3 terminal switch you can do dual fans

It does, via the relay . In your original diagram the relay isn't doing anything
