That would certainly be an interesting hack :)...this is my second Acer Ferrari 4005. I replaced the first one within two days thinking there was something wrong with the fan and hence the loud fan....nope. The second one is the same. I am sure, someone would disagree with me here..I did not dare compare the noise of this laptop with an idling SunFire V250, but now that I am sitting right next to one, I can safely say that a SunFire V250 and Acer Ferrari roughly make the same sound. Or the annoying whirring sound factor, is the same :). It's not overly loud but it is certainly bloody irritating. And I can't explain why the hell did Acer not design this laptop with a fan speed that could be managed. And let's not start on the broken (many spelling mistakes) ACPI implementation.
