Comment 9 for bug 653129

Quick update: I should mention that I do get 2 different fan speeds: Constantly on but slow and a higher RPM speed. It doesn't seem to be controlled by the kernel acpi modules but rather a hardware behavior, platform independent.

My CPU right now is at 39C and the fan is in its "quiet" state (still spinning but slower than the "top speed").

Because it is a brand new laptop the fan is quiet whether spinning fast or slow, but you can definitely tell when the speed changes.
