In
this thread we talked about freeware tools to show multiple hard drive temperatures in the system tray (I settled on Crystal DiskInfo).
In that thread, the utility "
RealTemp" was mentioned. While it doesn't display hard drive temperatures, I recently came across it again while looking for a tool to show cpu temperatures in the system tray.
RealTemp does a very nice job of showing cpu core temperatures in the system tray and is free.
One nice feature is it can show a separate tray icon listing the temperature of each cpu core, OR it can show the max temp of all cores -- a nice alternative.
I find Monitoring the temperatures of hds and cpu can be quite useful if you are worried about overheating.
