I have tried to reset smc on iMac as mentioned above. Disconnecting power from the source and later holding the start button. But my problem is still persistent. Fan runs continuously at higher speed. Can u help me with this problem.

Have you blown the dust out of the intakes lately?
What temperatures does this App report? Especially the CPU & GPU.
This App can be used to speed up the fans, all my iMacs would be dead without it.
Never ever ever drop fan speeds below the speed that the Mac itself is calling for.
MacFansControl…
wow it worked!!!!! But it starts working once logged in. If it’s logged off it isn’t working.
anyway thanks for support.
If by logged off you mean the computer is turn off - that is normal. Nothing will be working when the computer is turned off.
