Were the fans working properly before you used HWiNFO ?
HWiNFO is not performing any permanent changes to the system. Shutting down the machine, removing power adapter and battery and waiting a few minutes should fully restore all worst-case changes.

yes the fans are totally working fine before i installed hwinfo.. tried that couple of times.. i even tried disassembling my unit to take out the CMOS battery.. but still the same.. im using hwinfo now just so my fan would work, but i have to launch hwinfo evrytime i restart to make my fan work.. i can enable the performance mode in bios to let my fan run at high speed all the time.. but i don't want that.. in hwinfo if i set my fan to system auto it turns to inactive..

That's really strange and it should not happen by using HWiNFO. Looks like a firmware issue. Perhaps a BIOS update together with Embedded Controller (EC) update might fix that.
Otherwise probably only DELL support might help.

I've had this issue for a couple of years, and I need a solution badly. I have alienware 14 and what you described as the problem is exactly what I have to deal with. Its seems like a common issue
