    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, but are faster and easier with an iMac service wedge.

    • If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case.

    • The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" (9.5 mm) into the display. You risk severing antenna cables and causing serious damage.

    • Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

    • Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.

    • Run the tool up along the left side of the display.

    • While the opening tool did the lion's share of the work, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.

    • Set the iMac face-up on a table.

    • Starting from the top right corner of the iMac, insert a plastic card between the display and frame.

    • Be careful not to insert it more than 3/8" (9.5 mm), or you may damage internal components.

  11. iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 11, imagen 1 de 2 iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 11, imagen 2 de 2
    • Gently twist the plastic card to open the space between the display and frame, and cut any remaining adhesive near the corner.

    • Using too much force will crack the glass. Work carefully, and don't try to create a gap any larger than about 1/4" (6 mm).

    • Be sure to stop cutting before the iSight camera in this step, or you may damage it.

    • Slide the card toward the center of the display, to cut any remaining adhesive.

  13. iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 13, imagen 1 de 2 iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 13, imagen 2 de 2
    • Put the card into the corner again and let it stay there to keep the adhesive from resettling.

    • Insert a second card into the gap between the display and frame in the top left corner.

  15. iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 15, imagen 1 de 2 iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 15, imagen 2 de 2
    • Gently twist the card, slightly increasing the space between the display and frame.

    • As with the other side, move slowly to allow the adhesive to break, and be careful not to over-stress the display glass.

    • Only lift the display a few inches—it is still attached to the iMac by data and power cables.

    • With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.

    • If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the adhesive in the problem area.

    • Begin to lift the top of the display up from the frame.

  19. iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 19, imagen 1 de 2 iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 19, imagen 2 de 2
    • While holding the display up with one hand, use the other to unplug the display power cable.

    • Lift the display up enough to have easy access to the connections, but not so much that you stretch the cables and stress their connections (about 8").

    • Flip up the metal retaining bracket on the display data cable.

    • Disconnect the display data cable.

    • This is a delicate connection that can easily be broken. Be sure to pull the display data cable connector straight out of its socket, toward the top of the iMac.

    • Lift the display up to a near-vertical position.

    • At this point there is still a strip of adhesive along the bottom of the display, that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

    • Remove as much of the adhesive as possible by grabbing it at the outer edges, and then pulling or rolling it towards the middle.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.

    • Be very careful handling the display—it's big, heavy, and made of glass. The display has fragile edges. Avoid lifting the display by the corners.

    • Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface.

    • It may be necessary to slowly lift from one side, to peel against the remaining adhesive.

    • After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide when your repair is complete to replace the adhesive strips that secure the display to the rear enclosure.

  24. iMac Intel 27" Retina 5K Display Hard Drive Replacement: paso 24, imagen 1 de 1
    • If you are replacing the display panel, you may need to transfer additional components from the old panel to the new one. Compare the back of the old display with the replacement display. Note all cables, sensors, and foam cushioning that are missing from the new display.

    • If there is a wire or cable underneath adhesive tape, always pull the tape off first.

    • If the cable is glued to the chassis, use a heated iOpener or a hair dryer to soften the adhesive first. You can then slide an opening pick underneath the cable to loosen it. Never pull directly on the delicate connectors.

    • Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.

I did successed this. But after just turn on, main fan spins faster than ordinary status. About 1600 rpm. Ordinary rpm is just 1200.

How can I fix it? Not by software solution(i.e., fan control app), help me by hardware solutions, plz.

*Replacement HDD : WDC WD40EZRX-00SPEB0

*iMac (Retina 5K, 27-inch, Late 2014)

*3.5 GHz Intel Core i5

*AMD Radeon R9 M290X 2048 MB

Dear Changwon, i also own a Retina imac (i7 Radeon 295). Harddisk has been changed by the distributor – they sell customized "Edition iMacs". Now i have the same problem as you subscribed - from day one. Fan speeds up to 1700 / 1750 rpm after a few seconds after power on. Next week my Apple certified distributor will check my iMac and hopefully fix that "noisy" problem. I will inform you, when we will be successful ... Have a great time so long. Greetings, Markus (mr@i-map.de)

Markus -

Did you use a original HDD with apple Firmware or a normal HDD? If u use a nomal HDD with non apple Firmware, you have the Fan Problem.

Klausi -

And it just show 1.8TB but that HDD is 4TB.. :( Help me anybody..
