I believe you mean the PG 500. The temps do overshoot a bit but it's not too bad. I have never heard my fan turn off if the switch is on. All I can tell you is that this smoker/grill is amazing. I love everything I've made on it and its a pleasure to use. I got rid of my gasser and use this for everything. The only downside as a grill is that it's a little dark and hard to see. I have had plenty of space for us but if you want to cook 30 burgers at once that will be tough. I've had no trouble fitting in 10-12 burgers, 6-10 chicken breasts, or 4-8 steaks. And I love what I've smoked on it!
