| Hello, I have a Deskmini B860. Sometimes when it starts up the CPU Heatsink fan will be stuck at 80-100%. The only way to fix it is to turn it off, and unplug it. I am on the most recent BIOS. 6.01. And Fan is set to Silent in bios. I have also tried to set it with a custom curve. |

Hi RAIDER600, there are a few things that can cause fans to spike/stick: 1. Uninstall any monitoring software you are using, a sensor being misread can cause the fans to spike and essentially freeze the fan control from the BIOS. 2. Make sure your fan/s are set to PWM mode in BIOS 3. Check if you have "Intel Dynamic Tuning Technology" installed, if so, uninstall/disable it. If not, install it from your product page: https://www.asrock.com/nettop/Intel/DeskMini%20B860%20Series/index.asp#Download" rel="nofollow - https://www.asrock.com/nettop/Intel/DeskMini%20B860%20Series/index.asp#Download -------------
