Comment 6 for bug 742257

Ok, so your fans are both running at 2400 RPM, so they're definitely running - at least according to proc. You should be able to barely hear the fan run if you put your ears close to the top of the keyboard?

Your temperatures look fairly stable, but a bit on the hot side (like mine) - but I'm not sure of the typical running temperature when running OS-X to compare against.

When running cpuburn (burnMMX, burnP6 etc.), the temperatures go sky-high and the fans don't spin up - This definitely looks like a fan control issue to me.
