@Luis - we sell the video cards in the parts list to the right and we also offer a component level repair where we can reflow the chips on the card itself. if you would like to learn more about the repair options, you can submit a quote request using the send-in repair option at the top of our site.

@CB - it depends which exact model you have. Some were offered with discrete video cards that are replaceable.

@Tim - if you have an upgraded video card it is a separate part. if you go to our Parts By Serial section, you can put in your iMac serial number to get a part list. You'll need to remove everything sitting in front of the logic board to remove it.

@Steve - we are just doing a general take-apart in our videos. If you think you can remove a part you need ahead of the video, it is advised.

@Bmantheman - I'm not aware of one going out more than another. You can install some fan control and monitoring software and see if you can tell which one it is if you can't figure it out from the location of the sound.

Hey there! im pretty sure one of my fans is about to give out, very loud rotating noises, (taught it was my HDD but changed it and it's same sound happens) How can I tell wich fan is causing this. im planning on purchasing my replacement parts from you guys. Is there a "known" problematic fan on the late 2009 i7 imac 27inch? Let me know! thank you!

@Peter - you'll most likely need a new board.

My e-mail address is msweu@yahoo.co.uk. I have a 27" Imac, the A1312. I accidentally cracked the top glass and I want to replace it. Please give the price and replacing details so that I buy and replace it.

@Robert - The magnetic strips are part of the Aluminum front case. There is no need to remove the magnetic strips. Im pretty sure they are held on by adhesive, so if they are removed, you would probably need to apply double sided adhesive to put them back.
