Do the iMac G3's have fans inside?

    I just got mine. (And I'm using it to type out this post)

    Now, this thing runs quite warm. In the little vents around the handle on the top of the machine, I can feel it getting quite warm. Does the original iMac have a fan? By the way, this iMac is a 350MHz Slot-load from 2000.

    Only the tray loading G3 iMacs have fans. Your iMac is a slot loading G3. It does not. They do get warm, almost hot. This is normal. For better airflow, elevate the front with the iMac's stand.

    As mentioned, the slot-loading iMac G3s do not have a fan - they cool themselves using convection. The vent should be noticeably warm when in use, as that is where all of the heat exits the machine. CRTs get hot, so it's normal.

    Oh, okay, so what would happen if I installed a fan in it?

    ----------

    So, the cooler air is dragged into the machine through the bottom? I already have it sitting elevated, so there's a start.

    I put a fan in one of mine because it would overheat and freeze. It just move more hot air around the case and out the top. But unless your iMac is freezing from heat, you shouldn't install a fan or open the CRT half of it.

    i had good luck with a large fan mounted on the outside (laying on top) of the handle pulling the hot air out. with a speed controller, it was not noticeably louder than stock, but much cooler.

    ugly as hell... but effective and cheap FTW!

    You can try placing it on a laptop cooling pad.

    It's not overheating or having any other problems because of the heat, I was just wondering if I could just make it run a little cooler, that's all. But thanks all for the answers.

    @Intell: I've got a bondi slot tray-loading iMac G3 last weekend. Pretty aweful eye-candy! :) But there's one drawback: the fan is always running - even when in Sleeping-Mode.
    I did perform PRAM-Reset and SMC-Reset three times without any effect. System is os9.2.
    Do you or anyone else have a clue how to tame that permanent fan-activity?

    And one more thing/question: using the iMacG3 keyboard: I can't figure out how to "foreward" delete text-input ...

    being a Pre Uninorth machine, I dont think the iMac G3 Tray loader supports deep sleep, so the fan will always be running the entire time the machine is turned on. (im guessing tray loader is what you mean, since there never was a bondi blue slot loader)

    Turn off the num block and press the comma key, is that what you meant?

    Problem on the iMacG3-keyboard is: I even don't know how to turn off the num-block ...
