Installed Ubuntu Server on old Compaq Desktop - Fans run full-speed all the time. What to look at?

I installed Ubuntu Server on an old Compaq Desktop machine, for a development server. (Don't have the model number handy, can verify later).

"I would look into making sure ACPI and APIC and everything else is enabled for the motherboard, and also in Ubuntu. The motherboard may only have drivers that are windows-compatible because of some quirk in how they are made.

You don't mention how old the system is. In my experience only the last few years of Compaqs have played really nicely with Linux."

"manually change fan speed in Ubuntu (many motherboards):
as root:
echo 1 > /sys/class/hwmon/hwmon0/device/pwm1_enable
echo 60 > /sys/class/hwmon/hwmon0/device/pwm1"
