Hello,
I work for a K-12 school district and we still have a number of Power Mac 5500/225 models in service in our classrooms. We don't have the money right now to replace them and the CPU fans have begun to go on them - they make quite a bit of noise and it distracts the kids, particularly in the younger grades. Is there somewhere that sells replacement fans/sinks for these? I imagine a nice copper cooler could probably passively cool these things, but I'd like to hear from someone else who has done it - I'm thinking a VGA cooler with some thermal adhesive since the clips won't match up. Any thoughts?

Or, if someone feels like giving us some old iMacs that'd work too

Thanks,
-Jeff

You should contact shreve systems and see if they have the parts. If not, they can tell you how to get them.

It may be a simple, stock fan that you can find at any electronics wholesaler for pennies (in bulk). A newer one would be quieter, too. I can't remember how hard one is to pull, but a lot of the later machines (prior to the iMac) used off-the-shelf parts for stuff like that.

Good luck, and let us know what you end up doing.

I am surprised that there are CPU fans for a 225 MHz 603 CPU, the 200 MHz 603 in our 4400 does not even has a proper casted heatsink it is just a thin piece of metal bent and placed on the CPU.

My advise is to get Panaflo fans and use low rpm fans as "thick" as you can get. A 80x80x25 will be much quiter than a 80x80x10 mm at a given airflow
