Here, have my configs." :-I Is your temperature of 66° F or C? System temperature or surrounding room temperature? I have an old computer whose fan has quit as happened once before. CPUs generate considerable heat, I see system temperature and realize the fan is much more critical than whether the room temperature is a chilly 20 C or sweaty (for humans) 35 C. I don't use that old 2001 computer much, am getting ready to put together a new computer from parts to run FreeBSD and Linux, likely Gentoo; otherwise I'd order a Socket A fan. When I do use that old computer, I open the case and prop a hair dryer to run at low, ambient-temperature air pointed at the CPU. This keeps the CPU down to 47 C according to the BIOS/CMOS screen. This is cool for the CPU if not for us humans. Tom
