Hi there,

I've got an Aspire 1522 Wlmi too, and have had problems with overheating since shortly after I got it. I managed to kill it after about 11 months from overheating under both Linux and Windows with any serious CPU intensive task. It got worse the older the laptop got, and although I found how to avoid the problem not long after I got it, in the end it couldnt restore a backup before it switched off, which meant I couldn't work around it any more.

Although it does mean you can't use the CPU to it's fullest potential, the two methods for Windows and Linux that keep me going are:

Install RightMark under windows, and force it to 1.1V/800 Mhz.

Under Linux:
    modprobe powernow-k8
    modprobe cpufreq_powersave
    echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Yeah I know, it'll force your CPU to run at it's slowest speed, but if you're desperate, then give it a go. There's a package called cpufrequtils in the repositories and you can edit /etc/default/cpufrequtils and change the governor to powersave so that it works on boot (disable powernowd if thats still around with BUM).
