I've made some experiment with my BIOS settings, and I'm happy to repport that EST seems ok with my CPUs : cpu0: <ACPI CPU> on acpi0 est0: <Enhanced SpeedStep Frequency Control> on cpu0 p4tcc0: <CPU Frequency Thermal Control> on cpu0 (repeat for CPU 1-2-3) I've had 3 settings to play with. One of them was for enabling processor power management. The second one was about "C1" versus "C1 enhanced", and when switched to "enhanced" my power supply started to emit a very strange high pitch as soon as FreeBSD finished booting, and stopped as soon as FreeBSD was unloaded. The last one was about disabling or enabling "GV1/GV3 only". This one was the good one for me. My current dev.cpu.0.freq is 125 MHz, I'm monitoring CPU temp. too, but it will need some time to see if CPUs are running cooler. thank you all for your help, Pat
