Case fans not working

[Buizel10]

So I installed a graphics card that is 82 degrees Celcius and I noticed my back case fans were not working.

I have them installed in "SYS_FAN 1". I set the BIOS setting for header "SYS_FAN 1" on Full Speed but still not working.

This was a OEM build from a store similar to NCIX PC, memory express.

I have the motherboard GIGABYTE GA-B85-D3H.

 

EDIT: I think its the fan or the header being broken and not outputting power.

Did these come with the built PC or are these after market?

Try connecting to the power supply directly. That way you'll know if it's the fan's problem or if it's the motherboard header's problem.

I need a adaptor. I will first try other header on the mobo then buy a adapter if that dosent work.

Take it back to memory express, how long has it been? I go to memory express often they're pretty good with their policies and warranties, I wouldn't mess with it, let them do the work

Okay then how abou t simply plugging that fan into different headers on the motherboard? If the cable can't reach then unscrew it and hold it with your hand to plug it in. All you have to do is to see if it works. Otherwise, you can plug in anohter one if your case fans (I'm assuming you have more than 1 case fan in your car ) to check if it's the header or fan that's the problem.

Tryed that now, BIOS detecting that the fan is defective rather than the MoBo header.

Alright so sounds like the fan is not working then? Confirm by plugging in a working fan in that original header?

How many pins are on your case fans. if it 3 pin. I think you may have wrong setting. 4 pin is pwm. which sends pulsating voltage which non pwm fns cant handle since the rate electricity is so rapid that its not enough for the motor on non pwm fan to spin. As for 3 pin fan. They are controlled by voltage form like 6v to 12v etc to control fan speed. So maybe in your mobo bios there maybe a fan setting that allows you to change it to pwm mode or 3 pin mode. I know on my motherboard I only have no option for changing it. So I had to use fan controller.
