    Can you overclock an iMac G3?

    I was interested in overclocking an imac G3 for fun with my mate. I found the 400MHz graphite SE+ in a skip looking lonely, so i cleaned it up and gave it a new home. I was wondering whether you could overclock it, as my freind has had a lot of experience, and i thought it'd be fun.
    Let me know

    I've seen a site which detailed this but I don't have the url. Try a search on Google for something like "imac G3 overclocking". It involves reconfiguring resistors that are mounted on the motherboard so it is not risk free.

    Keep in mind that those iMac models don't have any fans...cooling is entirely passive, by convection.

    Thanks Cradom. That was the one I'd seen. There is also a page for later model iMacs at:
