PowerMac7 Fan Control

Added a mechanism for users to tune certain fan control parameters
Use drive bay temperature sensor to control the backside fan

Found this in the release notes of MorphOS 3.12 so where can i tune these parameters?


G5 Thermal Management

Basic sensor support for PMac11,2

And what does that mean? Can i run MorphOS 3.12 now on the Quad G5 with 2.5 Ghz?

Didn't we talk about that stuff yesterday (or was it already today)???

PCIe G5 work but aren't officially supported (just like my iMac), you just have to supply a supported Radeon (ATOMBios or a rare Apple one) and NIC ( look here).


As for the fans, during the initial beta phase cyfm provided me some fan related shell tools for the iMac but I can't find them on the ISO. So no idea wether these where just forgotten or if I should have looked for something else.

I'm pretty sure we didn't talk about it.

Actually, there is now away to control certain parts of the fan control software on PowerMac7 machines. However, due to an oversight on my part, the tool to do so never made it to the ISO.

I'll make sure it gets included in MorphOS 3.13, in the meanwhile you can download it here:

It's a command line tool using the standard ReadArgs() interface, so if you run PowerMac7FanControl ?, you'll get a list of possible arguments that you can give it that are hopefully more or less self-explanatory.

Hi !
Does this work on imacg5 too ?
I just registered my imac, everything is working, except the fan control, so the machine can goes up to 100 °c.
I know it is not supported yet ;)
Except that, it is a great machine for Morphos !
I could do betatests if needed.

Hmmm, mine for sure doesn‘t go as high as 100 degrees......

Does FanControl set permanent changes? Or is it needed at every boot?

btw: reduced G5-2.3GHz CPU-Temp from 76°C to 69°C without more noice.....very fine!


EDit: Seems not to be permanent.

Hi !
Could you tell me the exact command you use for this ? I don't understand well how it works...

Thanks ! :)

In my case I want max CPU-Temp of 70°C:

> CPUFanControl CPUTemperatureTarget 70

> CPUFanControl ? gives you all comands.

Thanks ! I will try on my ImacG5 ;)

Ok thanks for the info. I hoped it could work on Imac too because on open firmware it is named powermac...
Anyone has the Imac version for tests ?

Thanks !

The key is in the number. Your iMac is PowerMac12.
