This may be a fix. A new GPL'ed OSX application called "smcFanControl" allows a user to control the minimum fan speed on Intel MacBooks through a simple interface. It appears that this minimum fan speed setting carries over into Edgy without issue on a multi-boot system, but more testing is needed.
A firmware upgrade helped cool the CPU temperature on my MacBook from 70C+ to 55C-60C during extended "normal" use. With the above "fix" [minimum speed of 4500rpm (will probably lower this later)], my current temperature is 41C after an hour of "normal" use. It's nice to have a MacBook that I can call a "laptop". I hope this continues to work without issue. -- MacBook gets extremely hot under Linux https://launchpad.net/bugs/52852 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
