• Save your VI as TemperaturCase.vi
• Add a case structure within the loop. Connect it to the "Greater than" wire.
• Add a Beep.vi inside the True case
• Set "Use system alert" to False
• Adjust the frequence to e.g. 800 and duration to e.g. 100 ms
• Set the threshold value high, e.g. 95, to avoid too many beeps
• Run your VI. Try changing the values for frequency and duration
• Save your VI
