Fan problem iMac

Hello everyone, I'm new in the apple support community. I have a problem with my iMac. The fan go extremely fast when I do simple operation and the system is very cool. For example now I have only safari opened and the fan is going at over max speed. I will send a screenshot of my situation. I tried the reset of SMC of PRAM and I also tried to use software like smcFanControl, Mac Fan Control and SSD Fan Control. I haven't changed my hard drive so I can't understand why this problem occurs. Only sometimes the fan go at the standard speed which is 1400 rpm and noiseless. The fact is that the fan goes over the maximum speed so I think that is like Intel detects an emergency over heating. Before i had this problem, to hear the fan noise I had to play at least one hour of Tomb Raider ad the fan was just 2800 rpm which is acceptable and according to mac fan control should be the max speed of my Mac. I'm desperate, please help me!

You have MacFanControl in Sensor-Based value mode.

select: Sensor-based > Change Control and look to see if you have

"Temperature that fan speed will start to Increase" and "Maximum temperatures" set properly.
