I am a fan of the iBook, but that is not what this post is about. I have a 500mhz iBook that I bought brand new in 2001. Since I have had this, I have not once heard the fan go on. I know the thing has one it just doesnt wanna spin. Sometimes when I am playing games for a while or when my computer gets hot, it gets very sluggish or freezes (it only froze once). Do you think this is noramal or do you think my fan is broken. BTW, my friend has a 700mhz iBook and ive heard his fan go on alot, but i though that might be because of the speed diference and his gets hotter.
