OK, y'all have got me so freaking paranoid - I gotta quit lurking the Forums... Anyway, my new Blackbook (2.16/160) is currently running closed-lid (Speck shell, too), under a riser for my external monitor. The only apps running right now are Safari and Adium. The temp report from iStat Nano is: Fan ~2800 rpm CPU A 61C / 143F Heatsink A 55C / 131F Heatsink B 57C / 133F Enclosure Bottom 35C / 95F Northbridge A 55C / 131F Northbridge B 54C / 130F Look basically good to you? I'm thinking all's fine, but this is the first notebook (all desktops to this point), and hopefully replacing the work machine, too, so there's a lot riding on this one.
