I installed speedfan to be able to change fan speed and check on my CPU temps:
I got technically 4 fans installed (aside from the GPU)
3 Case fans
from what i have read so far the "fan 1" on Speedfan is my Heatsink fan. I also have fan2 and fan 3. unfortunately i was expecting 4 fans.
Open Hardware Monitor - Very similar to Hwmonitor, but with some extra features. Open Hardware Monitor does not see my ups status while Hwmmonitor does. Open Hardware Monitor also allows fan speed, but it is manual only. http://openhardwaremonitor.org/
You can either slow the fans with software or your finger to see what fans are showing on what sensors in software.
i downloaded CPUID HWMONITOR
i only got CPU, system fan 1, system fan 2 on fans PWM
all 3 of my fans are identical I'm sure the one not detected is still PWM
i got the temp for the CPU which is great... only prob now is the fan detection. and I'm sure it's connected properly
