Use this guide to replace the fan.

Don't forget to follow our thermal paste application guide before you reinstall your heat sink.

  • Remove the following ten screws securing the lower case to the upper case:

    • Two 2.3 mm Pentalobe screws

    • Eight 3.0 mm Pentalobe screws

  • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

For all the screws you use the P5 pentalobe screwdriver?

Carlos - Reply

Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.

Fredrik -

Is the Pentalobe screwdriver mentioned in the tools list? I did not have one so I used a filed down flat blade screwdriver. Not a fantastic idea, but it works.

Alex Birkett - Reply

Yes, it's mentioned on the top of this page. P5 Pentalobe to be precise. I didn't have one either, so I bought one from iFixit and that works fantastic. An absolutely precise fit, which is important especially when you might open your MacBook a couple of times during the years you own it. Not using the correct tool might do more harm to the screws than you want! I once had this with a Lenovo Yoga 3 Pro, which has Torx screws (T4 I think) and I used cheap Chinese quality tools, with the result that both the tool and one of the screws are damaged.

the macbook in the picture is 2012. does it has the same structure as 2013?

Edison - Reply

I never, ever, ever considered using anything but the correct tool on the Pentalobe screws. Too easy to strip and void your warranty (if still in effect), as well as make it almost impossible to get inside later for another upgrade or repair. The Wiha P5 Pentalobe screwdriver fits like a glove and costs only about $11 (a fraction of your drive's price)at Get it!

is P5 supposed to be for all 10 screws? it works on the 2x 2.3mm at the top, but not for the 8x others for me. what size screwdriver for the 3mm? thanks

monsieurescargot - Reply

Yes, the p5 works for all 10 pentalobe screw heads for bottom cover. The the different size mm reference only refers to the difference in length of the screws, but again both heads are p5.

Wedge your fingers between the upper case and the lower case.
  • Wedge your fingers between the upper case and the lower case.

  • Gently pull the lower case away from the upper case to remove it.

  • The lower case is connected to the upper case with two plastic clips near its center.

  • During reassembly, gently push down the center of the lower case to reattach the two plastic clips.

There are two screws that are shorter-they go to the back near the vent.

This was already mentioned at the start, it says 2x 2.3mm screws and those are coloured red instead of orange for the other ones in iFixit's image.

What is the black vinyl-y sticker on the inside of the case (some sort of shield?). I was forced to slightly puncture it in order to replace the feet on my laptop. Thanks in advance.

  • If necessary, remove the plastic cover adhered to the battery contact board.

Do you know where I can purchase this plastic cover? Mine is missing and no one will work on my computer without it.

There is no point on going near the battery or logic board. I cut out these steps with no issue. It is precautionary but unnecessary.

  • Use the flat end of a spudger to lift the battery connector straight up out of its socket on the logic board.

  • Be sure you lift up only on the connector itself, not the socket, or you risk permanent damage to the logic board.

I have a friends MacBook Pro that has some water damage that caused the MacBook not to be able to use battery power, but still work when plugged into A/C. Upon further inspection I can see visible corrosion on a few of the 9 cables going from the battery connector to that small circuit board. Is it possible to just replace that circuit board?

jramsey21 - Reply

I have the some problem. I was thinking to replace the whole battery but I am not it will solve the problem. Any suggestions?

salvatorebarbera -

Sometimes it can be enough to just clean the contacts without having to replace the entire board. Dosent work for complicated IC's like plcc type, where corrosion is underneath the chip. Here you will have to reheat and reapply the IC.

andrehedegaard -

Have either of you replaced the battery and/or circuit board to fix the MacBooks with the water damage ? I have the same problem with the MacBook working fine when connected to power but dying immediately when the power cord is removed.

Steve - Reply

Hi, Steve. I had the same problem: Macbook Pro 15 retina with coffee damage. And it worked fine when connected to power. I made it working after replacing the whole battery. It seems that circuit connected to the battery becomes disabled to prevent short circuit.

Vadim Gribanov -

When placing the battery connector back into the socket on the logic board, check that every part of connector is pressed down. You should hear a soft click when it's back in place.

Ethan Tarquin - Reply

Thanks for the comment. My MBP isn’t powering on after I walked through these steps, and I assume it is because the battery connector isn’t fully connected. (I can’t check yet since I borrowed the pentalobe screwdriver)

Caleb Steinborn -


I thought I made sure it was connected but when running the computer it only detected the battery but couldn’t power it. I had to run with power adapter. Also it didn’t charge. I guess some pins were connected but not all. To verify that all were connected I removed the plastic cover, placed it carefully completely flat, and then reattached the plastic cover. After that it worked!

Jonas Ehrs -

If I only want to replace the trackpad cable, then which steps should I skip? This step seems unnecessary

Parth Gudhka - Reply

  • Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.

If you miss or let this step for later like I did, the power left in the battery even though the computer is completely shut down, will screw up the I/O board cable like I did. I noticed this after I put all the pieces back, turn the computer on and surprise, no wifi hardware is detected. -.-

I put a small piece of blue painters tape on the battery connector contacts to prevent it from accidentally making a connection and shorting. This helped keep things a bit more protected.

LaymanLab - Reply

That’s a great idea!

David Lilliebridge - Reply

I used a small piece of paper to prevent the connector from connecting, no need to wrestle with even low-stick adhesive.

  • Carefully remove the rubber fan bumper from the edge of the heat sink.

  • The fan bumper wraps around the heat sink and fits into slots in the fan duct. During reassembly, be sure to fit the tabs into the notches in the fan duct.

have lost the rubber fann bumper, what part do you have to buy to get this rubber? thank you

Walid Shraim - Reply

I changed out the noisy fan around 4-5 months ago. And lately it was back and I was super irritated about the poor quality of the replacement fan. Opening up the case and blowing on the ventilator some compressed air there was no noise whatsoever. I have this feeling that my “noisi fan” was actually the loose end of this rubber cover/bumper which could vibrate in the air flow channel. So verify that you insert rubber cover clips back to its slots on under the edge of the sink.

  • Use the flat end of a spudger to peel the four foam stickers off of the heat sink screws.

Ok, might be a dumb question, but where can I get the foam stickers, and are they absolutely necessary after reassembling the heat sink?

akdarstudios - Reply

  • Remove the following screws securing the heat sink to the logic board:

    • One 2.7 mm T5 screw (silver)

    • Four T5 screws (black)

Please be very very careful when reassembling. The four black screws seem to be poor quality and the top snapped off two of them when trying to tighten them. Does anyone know the size of these or compatibility from other models as finding a replacement for them is proving to be almost impossible without shipping them in for a ridiculous price…

Sophia Grace - Reply

The single screw on the left hand side on the image above, what type of screw is it? The one on my Macbook is a phillips head one. And for some reason, I couldn’t put it back. Any advise?

Mahmood Chowdhury - Reply

These should all be T5 Torx screws. There could be variations in the construction of the laptop compared to this guide, but I’d check out our ID Your MacBook tool to be sure you’re following the correct guide! If you are following the correct guide, be sure all the elements under the screw are properly seated, if they’re not well aligned the screw may not get a good anchor. Best of luck!

  • Use the tip of a spudger to push on either side of the the iSight camera cable connector to walk it out of its socket on the logic board.

I found this to be the most difficult step. There is a need to get positioned so that you have the leverage to push hard enough at exactly the point shown in the photo without risking slipping and perhaps damaging the CPU nearby

Tony M - Reply

Very helpful tip from Tony.

  • Peel the iSight camera cable off the fan housing to fold it out of the way.

  • Use the tip of a spudger to flip the tab on the fan's ZIF connector.

  • Carefully pull the fan cable straight out of its socket.

my cable was glued, had to be pryed up first.

  • Remove the following screws securing the fan to the upper case:

    • One 5.0 mm T5 Torx screw

    • Two 3.6 mm T5 Torx screws

  • Lift the end of the fan closest to the display hinge and remove the fan from the upper case.

Um, this guide should include steps for applying thermal paste, including instructions to clean the mating surfaces, and pictures showing how much thermal paste to use.

TheIronGiant - Reply

Hi @theirongiant, there are generic thermal paste application instructions linked in the introduction “Don't forget to follow our thermal paste application guide before you reinstall your heat sink.”

Sam Lionheart -


To reassemble your device, follow these instructions in reverse order.

Very good instructions, just completed the fan replacement, no issues -

David Tyra - Reply

Fantastic instructions, brilliant depictions for assistance. Thank you!

I completed this guide and it was brilliant, so thank you Andrew Optimus Goldberg and your contributors! I have a question about the Macbook's heat post-installation of a new fan.

I replaced the fan last night, and put everything back together. Today, the new fan is responding well under activities that would previously make the fan extremely loud and cause intense heat to build up on the bottom right of the Macbook: so far so good.

However, it seems heat is now being distributed to the keys and directly below the screen, and I can even feel it underneath the trackpad, and this is from simply turning the Macbook on with no applications straining the CPU.

Is this something to worry about? Have I possibly made a mistake in my installation, or is this normal for an ordinary working fan?

Thanks for any help that may be given. Appreciated

Ethan Tarquin - Reply

Is the fan you replaced the original one with the exact same model? While im no expert on this stuff my guess would be that it distributes air differently. I hope it works out for you though.
