19 Is your temperature of 66° F or C?
21 System temperature or surrounding room temperature?
23 I have an old computer whose fan has quit as happened once before.
25 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.
27 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.
29 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.
