THANK YOU GUYS. LOL it worked. I was worried that I probably screwed something up. Another question, I got my imac about a month ago, I downloaded fan control. But three days ago when I heard like a noticeable low whirring coming from my fan. It worried me. So a representative from apple told me to reinstall OS X. So I did with the installation disc and such. Now the fans are dead silent. I am afraid that they stopped but then again my temperature from istat pro shows that they drop and they go up. SO I assume they are back to their default settings right?
