I haven't touched anything system-related in a while. Two days ago I realized that my fan was on even though the system was under a very light load. After some time of this, I shut the lid to suspend it, and the fan was off on resume. That night the machine crashed, and /var/log/messages showed that it had shut itself down because it got too hot. I left it up anyway, and the same thing happened last night. Today, however, the fan suddenly turned itself back on, and now it's running constantly under no load. Is this likely to be a hardware problem, and I should just bring it in for service? Or are there software issues I should explore first? I don't have another OS loaded to see if things are different. I'm running ACPI, but have no idea what this means as far as heat management is concerned. Thanks. Jesse Sheidlower
