Re: sensors
Hi:
Thanks. Can the temperatures and fan speeds from BIOS be taken as reliable? I set up a very efficient cooling for the OEM cpus (Dynatron are small and thus fit this crowded board, though they are copper made and apparently much more efficient than those in aluminum) and very efficient ventilation for the rack, though such low CPU and system temp are surprising.
