Especially when doing something as long running and CPU intensive as compiling X, KDE, etc. The best choice is a small desk fan to blow air over your laptop while compiling. No, I'm not kidding. But it is not very portable. Another good choice is laptop-specific cooler that blows air on the bottom of your laptop. I'm using a Vantec LapCool2 that I am very happy with. Finally, you could configure a kernel with P4 clock modulation, and reduce your clock speed to something the CPU fans can actually deal with. The commands would look something like the following: # modprobe p4_clockmod # modprobe cpufreq_userspace # echo "userspace" >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 375000 750000 1125000 1500000 1875000 2250000 2625000 3000000 (choose one of the above frequencies, and do) # echo <frequency> >/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed This will hard set your CPU frequency to whatever you choose. Specify something lower than 3400000, and you will generate less heat. I would say something in the 2.5Ghz range should be good, and will still be faster than what happens when the processor goes into thermal overload. You could also do the same thing with a cpufreqd configuration, but you'll learn more this way! >System: Alienware 51-m 5500 >3.4 GHz HT processor >2 GB 3200 RAM >100 GB Hard drive > > Righteous bragging rights!! -Richard -- gentoo-user@gentoo.org mailing list
