I also get this in some 3D apps, especially benchmarks. |

It's coming from the case, not the speakers. |

Same here. The sound is loudest when running the "Mother Nature" test |
| 32 |
of 3DMark 03. Happening with every card I ever tried (an old Radeon |
| 33 |
9800, an X1950XT and my current HD4870). Could be the graphics cards |
| 34 |
then. But it would be interesting to know why this is happening. |
