it honestly sounds like i have a modded pc in my room with a bunch of fans .. it is annoying.2013 iMac has a fan idle speed of 1200rpm which is virtually silent.
You’ll need to diagnose why it’s not at 1200.
It’s not uncommon to have increased fan speeds if you have an i7 and the computer is doing something. Could be some background task. What’s the CPU temp and check activity monitor.

It is an i5 not the i7. My cpu temp is 35C.
Even if I restart the imac and let it sit idle the fan never changes. I would expect the noise if I was playing a game but not just when im web browsing etc. The fan NEVER drops below 1800rpm
Gonna try a SMC reset.
Yes try SMC reset and if that doesn't work than try an NVRAM reset. The iMac isn't modified in anyway is it?
The sensors all seem to give normal readings. I’m resintalling OS X right now. I’ll do the hardware test after.Do all the sensors give what appears to be accurate and normal readings?
You could try running Apples Hardware Test. Turn off the iMac, turn it on and immediately press and hold D on the keyboard.

If I can’t get the fan to behave normally I don’t know what I’m gonna do.
[doublepost=1532270140][/doublepost]Welp a reinstall didn’t help. I don’t know what the problem could be

Does the software you are using list ALL of these sensors and are the temps about the same at idle for all of them?

how do i do thatHmm everything there looks good. Honestly everything points me back to the SMC but you already reset it so I'm not sure. Just to test can you force iStat to reduce the fan speed?
What shows in CPU usage in your Activity Monitor? (Make sure that is set to show "All Processes", and not just "My Processes") You can click on the column labels to sort by %CPU, or whatever you prefer.
Set fans RPM to keep temperature at 150 degrees F/66 degrees C. Initially set all fans to 100% RPM for five minutes to blow out accumulated dust.Fan speed is always between 1850 and 2100 rpms .. it is LOUD.
I downloaded macfancontrol that allows you to change the fan speed but im not sure what parameters i should set.
