Fan noise not going away even after putting original HDD back again.


I have iMac : Core i5 2.7, 21.5-Inch, Late 2013

* I tried to upgrade HDD to SSD
* When I upgraded to SSD I started having fan problem: the fan started going at full speed. 
* Since I don't necessarily need SDD (and not sure how reliable are apps that control fan speed), I reverted back to originial HDD that came with iMac
* Unfortunately, even with original HDD back in its place, the fan problem is not going away. 

From what I have read, putting original HDD back should have solved the problem but apparently that is not working for me.

Any ideas?
