Dual Boot - Heat Problem
What I like about this Mac, is that I can boot into OS9.2.2 "Natively", rather than using Classic when in OS X. The reason for this is there is an OS9.2.2 application I need to use in my office that just dosen't work right in Classic. However, when in "native" OS9, the CPU HEATS UP TO 147 degrees! But the fan dosen't speed up to cool it down while in this mode. I have learned to not stay in this mode too long for fear of cooking my CPU, and I restart back in OS X, at which time the fan speeds up and cools the CPU back down to about 138 degrees, which seems to be normal for this machine.
The firmware boot rom in this Mac is 4.4.7f1. I know that there is a firmware update 4.4.8, which I have but have not installed, because the doc file that comes with it says "improves fan control behavior and reduces high speed fan cycling when running in Mac OS 9".
What I need is for the fan TO SPEED UP when in OS 9 "native" mode, to keep the CPU heat down.
That's why I never installed the 4.4.8 firmware update, as I think it might worsen the problem.
Has anyone done this update and does it make the fan hopefully speed up in OS 9 "native" mode?
As an alternative, I'm still running this Mac under OS 10.3.9. Would upgrading to Tiger solve this problem?
