Aurora R11, very loud after 5-10 minutes of very quiet

I just got a brand new Aurora R11 today with liquid cooled CPU and GPU. Opened it up. Plugged it in. Turned it on. Prompt me to give a minute for windows to set it up, asked me my region etc. Was extremely quiet during this. Then got to the home screen and after about 5 mins there is this very loud rattling or clicking noise that sounds like its rotating. when i restart the computer you can hear it slow down and get quieter and than speed back up. When I shut down the computer you can hear it go quiet. CPU and Graphics ae liquid cooled. I tried Thermal settings in AWCC and nothing changed the fans or noise. Temp stays at a 29c for everything, and fan speed is 28 percent for top fan and 12 percent for front fan. Will I have to pay if dell comes out and replaces a fan? if that is the issue. How can I tell if my CPU is liquid cooled. IN AWCC it shows my graphics card is but i cant find it anywhere for my cpu or under cpu. But in my packing slip it says cpu liquid cooling. THANK YOU very first PC EVER so I don't wanna mess with it.
