Hwinfo Not Recognizing All System Fans!


New Member
Hello, I have Dell Precision T3610 which has 3 internal fans and 1 CPU Heatsink fan. Hwinfo only allows me to control the CPU and 2 other fans but I am not able to control the 4th one. Plz tell me why is this so as I only want to control that 4th fan and want the System to control the other fans by itself. Need Help!
(Here I want to control Fan 3 but it does not show in Hwinfo)
