Sager NP6165

Hi. Few months ago (beginning of September) I ordered the Sager NP6165. Everything was great until earlier this evening when something went wrong. The computer started making a real loud noise that comes out of the left side vent. This noise occurs almost always even when the computer is Idle. It's as it is running at full power (I assume the GPU). Now, I have checked all settings, I tried setting so everything runs on the Intel GPU, I tried setting so everything runs on the Nvidia Optimus GPU and it made no difference; the random loud noise still occurs. I even reformatted the computer just so I am sure it was not because of some applications or what not but it did not help either. As a matter of fact, this noise I am speaking of kept occurring WHILE the reformat was taking place. I tried setting the power plan to power save, balanced , and every other possible plan but made no difference. I am not sure what else to do and I am really worried something is going wrong as this sort of noise never happened regardless of what intense or non-intense application the computer was running. It happens when the system is idle let alone when it is running something. Please help!
