Then add in that a lot of people new to AM4 jumped in with a new purchased board that didn't have supporting BIOS for 3000 chips, and they had to update it in an unfamiliar way (Flashback). I have no way of controlling my fans right now and would really appreciate any help. Most of the problems are typical problems caused by the new platform and Tomahawk is probably the most popular B450 board so it got a lot of attention. I have the latest bios but my bios for some reason does not have a way to use a graph to set the fans and can only put in values. I checked dragon center and it says that the fans are under control according to the graph but the rpm value is not in line. I set them to smart fan mode and pwm mode but there is still no effect.

I then tried going into the bios to manually change the fan values to the same as the ones before but the values are not applying.

I then wanted to try undervolting my cpu and had to go into the bios to change that and once I changed that and booted back into windows, I heard that my fans were going much faster than normal and that they were not being properly controlled by the dragon center. I bought the board a month ago and was using dragon center to control the fans which had some glitches here and there but was working for controlling my case and cpu fans. Hi, I have b450 tomahawk and am using 2 stock NZXT 120mm, 1 Phanteks 140mm, and the stock and wraith stealth cooler.
