    Hi All, I am now running MorphOS 3.11 on my MacMini 1.67ghz 1gig ram and plenty of
    free disk space. Seems like anything the is running, flash or YouTube on OWB causes my internal
    fan to go bonkers. Which I interpet to mean it's heating up fast and high. Is there some
    adjustment I need to make so I can run cooler? Any fixes at all I could impliment
    Hardware or Software? Would be much appreciated.

    Also now that I have 3.11 installed do I need to install anything else? After doing a clean install
    to 3.10 I did not install Chrisalyis, do I need to do that now? if so what version?

    Thanks,

    Brad Hansen

    Does that mean you've overclocked the MacMini? The fastest I heard of as a "stock" MacMini was 1.5GHz, which I have. ;-)
    By the way, welcome back Brad, glad you decided to try MorphOS again. 8-)

    The age of JavaScript is with us, along with DOM and CSS etc., so you can expect hardware such as our PPC CPU devices to be challenged at every turn on modern websites, so there's not much, that I'm aware of, that you can do to alleviate the CPU load, though there is a version, currently as a Beta, OWB v1.25 Beta JIT that has JIT JavaScript worked on by Marc "bigfoot" Olsen, and version 2 of the Beta is best to use, though I have come across a Limitation(s)/Bug(s) in it, that I've submitted as such, so I don't usually use it at the moment, but it's a W.I.P. so hopefully there will be a more complete release when MorphOS v3.12 gets released. ;-)

    I have Chrysalis v3.11 ISO installed on at least one of my systems, which is generally OK, though there are a few anomalies that I noticed with it, such as a French label in the menu of Crabum, that needed changing (for me), and PicShow was swapped by the Chrysalis installer to the default image viewer that just "locked-up" the whole system when an image was double-clicked on, and had to be swapped out back to LoView which was fiddly, which occurred on one of my systems (PowerMac 2.3GHz DP A1047 2061)
    MacMini 1.5GHz,10,2,64MB VRAM,1GB RAM,Airport, Bluetooth,A1016 Keyboard,T-RB22 Mouse,DVD-RW-DL+CD-RW,Iomega MiniMax,Belkin 6 port 3 x Firewire/3 x USB2,MorphOS 3.11,Mac OSX 10.4/10.5,A1138+A1139 PwrBk MOS v3.11,Model 5,8/5,9, & PowerMac G5 2.3GHz (DP)

    It's normal that Mac mini's fans start blowing hi speed when you run something that makes heavy CPU load (close to max). The fan speed is controlled by the hardware itself and it can't be tuned by software. Only thing you can do is to open the machine and clean it from the dust, it usually helps if it feels that fans do make too much noise and too easily.

    For YouTube I would recommend to get OWB configured properly to use overlay with full window playback, then it doesn't max the CPU load when you play videos, like it does in the small embedded view. Here are instructions how to do it.

    Last time I noticed the same in my Mini 1,5Ghz. Years ago Youtube worked smoothly but Web is becoming heavy CPU. Is it because of CSS3 or HTML5? Thank you to remind us I'll try it later.

    I think it's just overload of Javascript, they just stack Javascript scripts/modules over each other until everything chokes. Incompetence, lazyness, going the easy/first way they find, etc by web developers...

    Disabling Javascript from OWB makes web surfing surprisingly lightweight, but then you have to swap it on/off per sites constantly...

    You could look at replacing the thermal paste on the CPU cooler. It's a usual suspect for a CPU running too hot on older machines.

    But don't expect too much - after all, youtube has moved on from machines from that era, and the GPU probably isn't helping as much as it did on MacOS.
