Need help computer fan temp/speed??

[Jarrett_1]

I just downloaded speed fan and this is what it says.

Sys Fan: 0 RPM
CPU Fan: 1339 RPM
Aux Fan: 1015 RPM
Aux 1 Fan: 0 RPM
Aux 2 Fan: 1073 RPM
Aux 3 Fan: 0 RPM
GPU Fan: 726 RPM

Are these good RPMs or should I turn them down? But I also have a larger concern with this:

System: 32C
CPU: 36C
Aux0: -128C
Aux1: 50C (has a fire symbol)
Aux2: 22C
Aux3: 28C
HD1: 32C

One of my fan temps says -128C and the other has a fiery icon and says 50C I'm really worried right now my computer is only like a month old but this doesn't look right. I don't know which my Aux 1 fan even is I just know the case has 2 fans that came built in it

Aux0 is a sensor that doesn`t exist so ignore it. If your pc is under load the 50C is fine.

If you're PC doesn't have a (physical) fan controller then you're case fans should be already running at maximum.
Whatever you do, just DON'T change your GPU fan settings using that software (fanspeed). Get MSI afterburner instead.
