Exhaust fan and cooking time/temp
My wife and I are having a disagreement. She says having the exhaust fan on reduces cooking temp. I disagree, I’ve searched and can’t find any reference to it. Because we cook with gas, it releases carbon monoxide, which should be vented, along with gases and oils from cooking. Anyone have any data on affecting time/temp? Thanks.

These studies just looked at how well the fans do the task of removing or reducing pollutants though- not if they change cooking temperatures. I would hazard to guess they don't, because the heat is being applied below the pad at a constant rate determined by your knob selection. In an electric stove, that's controlled by a thermostat, and the gas stove is just a constant valve control flame. It's not as if the fan is blowing cool air down on the pan, heck it's not even that good at pulling heat away. Especially not in summer, when the air outside is likely hotter than inside your home. If I needed to cool my kitchen, I would not rely on the hood vent fan to do the job. From past experience, when it's hot in the kitchen and outside, turning the stove on -even with the hood fan - is not a pleasant experience.
If the hood fan made a significant difference, its usage would be mentioned in recipe instructions.
Worse, it would take forever to cook one egg sunny side up in a restaurant kitchen with a big commercial range hood versus a home kitchen with the fan turned off. Unsurprisingly, there's little difference in how long an egg cooks.
Same with pretty much anything. Boiling pasta is another fine example.
Up to you how to break it to her. I don't envy you right now.
Best of luck.
