[AN515-58] Fan Circuit Overvoltage (26V Measured) — Both Fans Burned Out

Hey everyone,

I'm reaching out because I had a serious issue with my Acer Nitro 5 AN515-58-58W, and I’d really appreciate any technical insight or help from those who may have experienced something similar.

Yesterday, I turned on the laptop normally, and after about 5 minutes, I noticed a strong burning smell. I immediately checked the fans and saw that both of them had stopped spinning. I opened the laptop and discovered that both fans were damaged due to a short.

To investigate further, I measured the voltage at the fan connectors on the motherboard, and to my surprise, they were outputting 26V, when I was expecting something around 5V–12V. This clearly overpowered the fans and caused them to burn out.

Has anyone encountered this kind of issue with this model?

Do you know what could cause such overvoltage on the fan headers?

Any known fixes or motherboard-level repair guidance would be greatly appreciated.

Thanks in advance for any help or suggestions!
