For some reason my Dell laptop runs hot and noisy in linux but cool and silent in Windows-8 Running # echo "min_power" | tee /sys/class/scsi_host/host*/link_power_management_policy makes the fan slow/stop. But I am not sure what it does!! [I dont want my laptop fried and its rather HOT out here right now :-) ] So is this command safe? Does someone know what it does? [Dont remember where I found it]
