    I barley had anything running, the computer was idle. In fact I wasn't even in the room but when I returned I found that the fans were approaching 4,000 RPM. I have never seen the fans go past 2000 rpm. Any idea on what the cause was? The only programs that were "active" was safari, calender, and my HP photosmart studio app. the laptop was plugged into the wall but that is nothing out of the ordinary.

    Thanks in advance.

    It could've been anything. Most likely one of the programs (probably safari) had something intense running (probably flash) which caused a spike in cpu usage which amped up the voltage which triggered the fans.

    Thanks for responding and I can't be 100% sure, but I don't believe I had any active browser windows opened. Even when I have watched flash video's ect, I have never seen such a response from the fans.
