Problems with Command center/loud noise from fans

Dear sir/madam, I have my Alienware desktop Aurora R4 3 weeks now, a problem just occurred yesterday. When I start the computer it makes a loud fan noise constantly RPM 100%. When I changed settings in Command Center to manual the fan noise decreases, but when I return to auto the fans stay stuck at 55% RPM and can't change back to manual. There are no problems with AlienFX, I can change light colors with no problems. I have noticed that it takes some time for lights to load, after windows 8.1 upgrade. Had no problems with fans after 8.1 upgrade. Please any solutions for this problem? Yours sincerely, Kevin PB
