hot/warm, I use a USB mouse and don't usually rest my wrist there or think of how hot it is, so I can't totally remember, but it's definitely the hottest spot of the laptop when I have checked. So maybe it's ok. I just was wondering because I haven't had the middle one come on, and am wondering if something is wrong and it'll wreck something.
Ok samething happened to me, during upgrade the middle fan turned out and the noise level increased.
After the reboot i think the middle fan isnt on anymore. I am guessing it kicks in if the laptop hits a certain temp?
