I recently upgraded to VMware fusion 2.0 on my macbook (sept. 2007 edition) and after starting up windows xp it causes the fan to turn on like crazy and the macbook gets heaps hot. It does this most of the time, and even after shutting down vmware fusion, the fan remains on, it really annoys me cause the fan is loud and it's not nice holding a hot macbook especially now that summer is just around the corner. Any suggestions on what I can do? My Macbook is 1Ghz, should i upgrade to 2? And i have 233mhz dedicated to xp, which should be enough for what im using it for, microsoft office 2007, that's all, don't use xp for anything else. please help. thanks.
