Hello! I'm wondering if the fans issue is still here after the new updates. I've wanted to buy an imac since 3.12, but the temperature/fans problem is holding me back :)
On my iMac G5 20" iSight running MorphOS 3.14, I solved the overheating problem using Frank Mariak iMacFanCtrl 0.3
tool (version 0.2 works with MorphOS 3.13 but not with the latest MorphOS update).
This tool allows to manually control fan /temperature avoiding issues and hardware failures with too high
temperatures when the system reaches too high CPU load.
As for the fan issue, I think in this thread it was well explained by sailor (post # 14) how to fix it ...
It is actually a bit uncomfortable to have to increase the revs of the three fans after each boot.
Surely, it would be more convenient to be able to automate this process during boot and live peacefully without the fear of forgetting to adjust the fans with the risk of frying GPU or other hardware, but unfortunately I don't know how to do it.
