I use speedfan myself. Runs well on my Latitude Cpi and my CPi-A. Working on mounting the dock and turning the CPi into a carputer...
I ran across this program and thought maybe someone else could use it as well.
My laptop fan doesn't kick to high until the CPU/HD temps are really hot. With this prog I set it to crank up at a bit lower temps to try and prolong the hardware.
If you want to control at what temperature levels your laptop fans cut on/off then give it a try. Alot of sensor options if your laptop/BIOS supports it.
This is for Dell laptops only, but there are other similar programs out there.
I'll give that one a try and see if it runs better on my older latitude. Thanks!
