SpeedFan Temperature Monitor
Full user review
"Excellent software. Saved my hard drives"
It's very easy to install, easy to use, very informative, and uses the internet to compare your hard drive statistics with others of the same model. If your fans are hooked up properly, you can adjust cooling to cpu usage.
No cons to report
After running a check of my hard drives, an advisory on one drive said that I had an issue that was probably a loose connection. On checking the drives, I located the loose cable into the back of the hard drive and replaced the cable. A rescan showed 98% performance.
Excellent way to keep track of drive temperatures. Hot drives break down very quickly or begin to skip. This software gives you total access to the SMART data for your drives, CPU, and video card.
