Where you mount the sensor decides whether it survives

The colour field is simulated air temperature above the cooktop, rendered onto the real range. Same cooking on both sides — only the sensor's position changes: under the hood (in the rising plume) vs off to the side. Step through burners and hot oil, fan off and on.

Case	Under the hood	Off to the side

The rising heat is hottest in the centre column under the hood and cooler off to the side. Mounted off to the side, the sensor stays within its 70°C (158°F) limit in every case — the recommended mounting position; mounted under the hood centre it overheats in the demanding cases (hot oil, or no fan). That is why Stovyn mounts on the hood's cool side.
