I recently bought a new computer (I picked the parts, they put it together) and it works perfectly fine after installing drivers and such. But every so often (usually about once or twice a day) I hear this noise coming from inside the computer case. The noise sounds like a small airplane in the sky as it approaches (gets louder), gets right over you (loudest), and then fades away. Although it's loud, it's not like a large airplane sound, as those sound more hollow. This sound is like a small airplane motor; the sound is more dull and higher pitched. It only lasts about 10-20 seconds and then it goes away. It's weird it sounds exactly like an airplane though, especially when it fades out. Any idea of what this could be? It doesn't seem to be doing any harm, but I just want to make sure. Specs in sig.
Thanks.
Thanks.
