sorry friend you are wrong. the p-180 does not have any built in temp monitoring features. i own one, i should know. also, you can monitor your hd temps on any mobo that supports S.M.A.R.T. monitoring.
to the OP, you can try speed fan. i know that it has the capability to read the hd temp from the probe in the hd itself. i use motherboard monitor but it has stopped being updated. there is another utility out there that will read all of the smart monitoring data off the drive. i cant remember the name off the top of my head, but i will look for you when i get home from work. im not sure if you really have to have the bios option enabled to be able to read the data. again ill look when i get home. if you have any questions about these, feel free to ask!!
edit: i just remembered that program was called smart monitor.
