Some background: I just swapped my X31 for my dad's X30 and I notice that the CPU and hard drive in this machine runs pretty hot. NHC consistently warns me that the HDD (5400 rpm) temp is equal to or above 55 degrees. I think part of the problem is the CPU temp. The memory has been upgraded to 1GB and an internal 802.11b/g (Broadcom) wireless card installed. I've cleaned out the fan and will check the thermal grease tomorrow.
In the meantime, I installed NHC in hopes of underclocking the CPU, but the options under that menu are greyed out!
