there is a diagnostic test for noise in your system.when you boot up in to your computer and when you see the dell logo TAP on F12>Boot Device Menu should come up.Select for Boot to Utility Partition and after that select the option for Symptom Tree.Select again the option for Abnormal Noise in the system.The diagnostics test will run test into one of your system fan that might cause that noise it could be the hdd, the processor fan.The diagnostic will turn on/off the fan, and will test to its minimum to its maximum speed.If you notice while running the symptom tree, you still have the noise.If your contract is still good, try to contact the DELL HARDWARE SUPPORT to verify what's really causing the problem.

Contact Dell's Technical Support and have them replace the fan.

The reason it is so loud when you reboot is because you are playing a game. When I play games it makes noise too except you don't here it much because you have the speakers on. But...since you immediately reboot after playing the game, the system is still very hot because of playing and since there is no speaker music to cover that up, you hear the fans even louder. My computer does that too because I use games continuously for hours so it starts to heat up and start freezing on me. That is why I am thinking about shoving an extra fan.

Oh, yeah I guess you're right. Well I really can't help you anymore because we have different models. Mine makes noise because it doesn't have a heatsink/fan combo and the system fan (i think is blowing out.) so there is really not much air in my system. I am trying to shove a fan on top of my heatsink.

Is there any way to reverse the system fan.
