Hiya
My fan recently died... and I tried to find the correct part for replacement... no joy.
So I opted for a generic size that fits... rewired it so as not to change the computers wiring loom.
It works but its noisy and runs all the time... probably because it was cheap & cheerful.

So I need to put a quieter fan in...
The original part # CHA9212FS-TF DC12V 0.43A SUPPERED.
I've scouted around ebay and found similar numbers but dont want to experiment as that will cost more in the long run!

Anybody know of a suitable replacement? part & number if you have one...

cheers

    Hi,
    It works but its noisy and runs all the time...

    Probably since you're missing the control lead or possibly tach lead.

    What happened to the original fan?
    Here's one in the UK:

    hiya
    The original fan wouldn't start up when required... if i gave it a poke on a blade it would start and run fine but as soon as it powered down it would overheat.
    I kept it... I removed the leads and attached them to the new fan so as to not lose any of the original connectors. the fan i have fitted had only 2 wires instead of the 3 on the original. i assume this is why it runs all the time...
    cheers for the link you sent me... i've seen when ever i search... it very pricey... considering thats about half the value of a used mac!

    gagsy,

    So did the fan spin freely? If not the bearings could have been dry or bad. Usually there's an adhesive cover over the bearings you can just remove it and oil the bearings. It might make it work again. I use a pen oiler you can get from the hobby shop.

    Yup too expensive. You could try a three wire squirrel cage type they're more expensive but a lot quieter.
