Posted December 14, 2019 Hi there, I accidently attached one of my fans to a JRGB2 output on the motherboard instead of a FAN output. It literally started smoking afterwards (from the fan motor thing). I turned computer off right away. Should I fear using this fan again? Why would the JRGB2 output make the fan start smoking anyways? Kind regards. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted December 14, 2019 Yup, dead. RGB is 12V like fans, but since the plug is different you probably ended up connecting it with reversed polarity.

Posted December 14, 2019 You can certainly use it, but the lifetime has probably been shortened by several thousand to tens of thousands of hours. So if it up and quits on you in the not so distant future don't be surprised. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

For fan they are 12V, GND, RPM, PWM. I would avoid using both. There are high possibility that header was also damaged. ^^^^ That's my post ^^^^ <-- This is me --- That's your scrollbar --> vvvv Who's there? vvvv Link to comment Share on other sites More sharing options...

Two, the header might be fine.
