For some reason my Dell laptop runs hot and noisy in linux but cool and
silent in Windows-8

Running

$ echo "min_power" | sudo 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]
