    Can't remove CPU on 2007 iMac

    I'm trying to replace the CPU on my iMac, but it's stuck! Is it possibly soldered on? If that's the case, I'm pretty much out of options aren't I? I was told to try using a hair dryer to remove it. I don't have a hair dryer, but I do have a heat gun. Is a heat gun too hot to use? Thanks.
