    Strange, I've never had issues with mine.

    The fans ramp up when needed and the temperature is properly controlled without any extra programs.

    In my case, without manually adjusting fan speed via the iMacFanCtrl tool, after about half an hour of normal use (without major commitments for the CPU) the temperature systematically rises from 45°C (just after boot) to 78-85°C and the Northbrige controller also reaches beyond 90°C. In this situation, I do not hear the fans start automatically and I suppose that in such temperature conditions hardware damages would be almost inevitable.

    In your case, at what temperatures do the fans automatically increase?

    Probably Frank could clarify our doubts about the automatic adjustment of the fan speed to the temperature increase.

    My fans ramp up drastically at about 85c cpu ( northbridge sits at about 72c at that stage )

    It sounds like a jet for a second or two then drops the cpu temps quickly to about 75c and it gradually goes down then.

    Normal usage for me it sits at about 65c - 70c for the CPU and 70c for the northbridge

    If you want to do it automagically at every boot, you can add this in your user-startup :
    Code:
    	C:talk2smu_setfan 0 2500 >NIL:
    C:talk2smu_setfan 1 2500 >NIL:
    C:talk2smu_setfan 2 2500 >NIL:


    You can modify 2500 by a number between 0 to 5000 (but 0 is maybe not a good idea ^^).

    /me doesn't put those lines in his startup but it's a good idea ^^

    This is no official tool, actually. I will probably release another update to the fancontrol UI tool that allows to define some minimum rpm values on startup.

    Welcome! Maybe you are also lucky with your temps, like I've been. Mine rarely gets hot unless I run Encore demos non stop, but the fans does their thing

    Mine is running fine without any fan issues or programs, hence hoping you might be also be lucky.

    There is a new version 0.4 of iMacFanCtrl available at morphos-storage.net which allows to adjust minimum rpm values and which can also be configured to skip the UI in order to avoid any additional user interaction on startup launch.

    Frank, what's still stopping you from adding the iMac G5 to the official supported hardeware list? To my recognition none of the iMac users reported real issues. Except the fan thing which seems to affect only some users and can get fixed by the fan control program .
    I am pretty satisfied with my iMac G5. 3.15 runs fine on it.

    You are right. My iMac have had fan problem, but with 3.14 all ok, I hope even with 3.15.

    Well, maybe for MorphOS 3.16. We typically don't add additional hardware support for bug-fix updates. The main reason iMac G5 isight isn't officially supported is that there are plenty of other iMac G5 variants that don't work at all to run MorphOS, so you basically are on your own to look one up that works.

    Speaking of smooth experience, starting with MorphOS 3.15, the released installation hdimg - dubbed #?hybrid.hdimg for this reason - can be booted via USB stick on various supported Apple hardware if you dump the raw image to some USB stick directly and modify the boot device in OF via

    Code:
    setenv boot-device ud:,\\:tbxi


    If it can't find a related USB device, it should fall back to HD/CD boot automatically. It will take a while until it times out on iMac for example but rather useful if you quickly need to boot from a MorphOS live image and don't have a CD at hand or your CD drive is already starting to act up.
    We will provide some more detailed information about this new installation feature at some later point.
    If you are already using a more complex boot menu or modified the boot process otherwise, this is probably less appealing.
    Unfortunately, the USB stick won't show up in the graphics boot menu which would make it even simpler but it seems Apple decided not to support that early boot feature back then.

    Since non of those can run MorphOS out of the box I doubt that ever to happen.

    Isn't this the same as with eMac and PowerBook G4?

    ? All I changed was my video card, and my quad is running MorphOS fine (I still need a network or wireless card). 8 GBs of memory (w/ >6 going to waste), but no problem leaving it all in place. I did have trouble trying to install a CMI based audio card and a SiI3132 PCI Express SATA controller card, but I'll try those again now that I have it running.

    Not enough expansion slots and they are too close together (wide video cards cover the nearby slot).

    Hi there, why does the G5-20" work and the G5-17" 1,9Ghz (x600pro) not?
    What hardware is the problem on the 17" model? Thx
