Lower GPU temperature, worst performance.

I have rtx3070ti with i5-12400, 2560x1440-170hz display. I have the settings all on low except for NVIDIA Reflex Low Latency on Enabled+BOOST. Until the last month I would max out at 82c on the GPU from the moment I get in the game and I would get a pretty smooth experience at a minimum of 160fps. The 82c is expected as the auto settings for performance on my GeForce Experience is set to max out at 83c. In the last month after one of the updates (BF's or maybe the GPU drivers?)I noticed the temp stopping at around 72c but I would occasionally get some frame-drop only for a second and then it goes back to around 150 and sometimes lower 100, depending on the location. Anyone else had it happened to him? The game settings are the same. Could it be on the GPU settings that changed from some driver update? I don't touch the settings on the GeForce Experience as I don't know the technical and didn't want to overclock randomly. Would appreciate any advice.
