I have a ThinkPad T41p that has had a variety of fan problems for some time. After my most recent repair things seemed to be working fine, but the other day I was compiling some ports and the machine just shut down in the middle; after some experimentation it seemed clear that it was just overheating under load and shutting itself off. (Looking at the temperature sysctl showed that it was getting increasingly hot until it crashed.) How can I monitor what is happening? Are there any ways I can find out from FreeBSD if the fan is even on, or how it thinks it is working? "systcl -a | grep fan" didn't return anything. Can I control the fan? I don't want to make yet another warranty call if they're gonna say, "It's working fine, it's your OS" or something. Thanks. Jesse Sheidlower
