Feb 14, 2016 6:45 AM in response to Mike Sombrioby Lucasvb,I wanted to do it but it didn't work or something I couldn't get the menu to open and I don't have a disk with it on it. But that might be a good idea, if I know how to start it because I couldn't get to open it or something.

Feb 14, 2016 6:49 AM in response to Lucasvbby Linc Davis,I don't understand your response. The question was whether the fans run at full speed in Recovery mode. Do they?

Feb 14, 2016 6:51 AM in response to Linc Davisby Lucasvb,oh sorry I was thinking of something else, I reinstalled the software trough the recovery mode and it still is happening and I thought you meant that. But I will try it now.

Feb 14, 2016 6:56 AM in response to Lucasvbby Mike Sombrio,Your iMac shipped with Snow Leopard on a gray two dvd install set. If you don't have those discs you have a couple options.
1. Order a replacement set of original install discs from Apple.
2. See if you can find the correct version of AHT here https://github.com/upekkha/AppleHardwareTest
3. Try this trick to run AHT without a disc. I have not tried it so I can't confirm that it works.
How to run AHT w/o the system discs
1) SHUT DOWN the computer (Don't RESTART... shut it down)
2) Hold down the OPTION + D keys
3) Press the Power Button (make sure to hold down the OPTION + D keys first)
4) Continue to hold down the OPTION + D keys until the system enters AHT mode
5) Let the app verify the hardware setup before initiating the test.
6) There are two testing modes. To select the "Extended Test" activate the check box below the Test button.

Feb 14, 2016 7:35 AM in response to Lucasvbby Mike Sombrio,I'm going to leave this to Linc Davis as he's much more well versed in OS X than I. Good luck.
