MSI Z790 Fans are flickering

Using a MSI Z 790 MB with a MSI 4080 RTX and a NZXT Elite 360 and Thermaltake Quad Riing Fans. The fans are flickering . Not permanently but sometimes. They flicker for just a Milisecond. Usind the beta version which support NZXT AIO, diabled CAM, no succes. Using the vendors software or open rgb works. i have disabled all programms at autostart. only msi afterburner was running and windows defender, which are both no rgb programs by any means. any suggestions.
ty guys.
