Samsung HL56186W Fan question

Question

I saw that you have posted an answer on the forum about this. I am getting this message on my screen that says "Check Fan #2". You mentioned that you cleaned the 2 cooling fans. Where are the fans? I found the 1st fan but not the second fan. The only fan that I found was the fan in the center once I took off the panel. Could you tell me where the second fan is? Thanks for any help!
