I popped off the fan connection from the logic board...Fix?

I am just too strong... I took my spudger and popped off the connection from the logic board. What do I do now???

Answered! View the answer I have this problem too

Is this a good question?

I had the same problem. Soldered some extra wires directly to the spots on the logic board and connected those with the fan wires (connector cut off).

Messed up one of the connections. Luckily I found an other spot on the logic board with the multimeter which was connected to the original pin. Haha. Nerdy.

sorry for the redundancy. I also have popped off the fan connector, and with it have lost one of the four pads on the board. My fans are running extremely high (7+K RPM . L/R).

i did the solder, and i'm guessing i bridge the solder in the fan connector, hence the high RPM.

does anyone suggest that i buy new fans and retry the solder, along with a better solder machine -weller wlc100, (not the cheap radioshack one ) with a micro tip and .5mm solder?

as for the four pads in the board:

can one chip off some flakes off the .5mm solder and solder this onto the board, or as suggested soldier the whole thing onto the board (the cable to the board?)

thanks!

I ended up just getting a new logic board since it was having another issue with the integrated display chipset and it wasn't very expensive since it's an older one (~$100). I didn't have experience with soldering such tiny connections and didn't have the micro tip so it was easier for me this way rather than dealing with it. The wires seems like a good idea though to deal with the tight space. So I guess look at how much a new logic board would be and see if it's worth it to buy the news fans and soldering equipment when that still might not work. For mine the fans had to remain removable to service other parts so soldering the cable to the board wouldn't have worked for me.

This is not a huge deal. I just accomplished this feat in less than 30 minutes with a $30 investment in a micro solder tip for my iron and 0.015" solder. You just have to have a little confidence and a little patience.

If your fan connector breaks off, DO NOT PANIC! You do not need a professional. If you're looking for help on this site, then most likely, you have done small repairs before. So, here is what I did, and I believe if you found this column, you can probably do it to.

1. Take the bottom cover off your Macbook Pro.

2. Using a set of helping hands, I clipped the edge of the fan connector in the tip of the alligator clips, and positioned them directly where I needed the fan connector on the board. If you have a decent set and play around with the positioning this should not be a huge deal.

3. Make sure you have a solder iron with a micro solder tip attached. This will look like a bent tip that comes to a needle point. They can be found at radio shack, that is where I bought mine this morning.

4. You need 0.015" solder. I would not attempt this with anything larger due to the solder wanting to "jump connectors" when heated.

5. With the fan connector in place, soldering iron heated up, 0.015" solder in hand; lightly touch the 0.015" solder with the iron just enough to solder the connection, YOU ONLY NEED A TINY DOT! Now, that you have a tiny dot on the tip of your iron, and the fan connector in place, LIGHTLY touch the first connector pin, rubbing in a vertical motion. you will see the solder start to coat the pin and make the connection to the board.

6. Now repeat three more times.

NOTES:

1. MAKE SURE YOU ONLY SOLDER 1 PIN AT A TIME AND DO NOT TOUCH OTHER PINS WHEN SOLDERING! This can accidentally bridge your connector pins and your fan will not work properly!!!!

2. I drank a double shot of expresso prior, HUGE MISTAKE!!! My hands were shaking the entire time, aside from the coffee, I was scared shitless! I still managed to pull it off with shaky hands, so, this should not be a big deal.

3. TAKE YOUR TIME. This was an easy fix. If you don't rush, you should be fine. Feel free to write me if you'd like to see pictures, and a video of my fans working after the repair.

4. This will save you $700 or more for a logic board replacement.

5. Celebratory whiskey shot. BOO-YAH!

BillyJo...i will be attempting this later today. Prior to soldering is there anything I have to disconnect except the battery? Can i leave the logic board mounted and connected during the solder?

by

What about the rear two connectors, are those also in need of soldering or are they just for holding the socket into place?

by

Thanks for the instructions and confidence BillyJo, just finished this fix!

I think the two rear connections are just for keeping the connector in place. However, they are the easiest to solder back on, so why not? I didn't find fine enough solder from the local shop (it needs to be really fine) so I just cut little pieces from my fatter solder and held the flakes in place with a tiny screwdriver while soldering. It's a good idea to have a fan speed meter in your OS to quickly check if the fan is working properly, smc fan control is an example.

by

I broke the connector, and one of the pins fell off and went missing. Is it a problem if I only reconnect 3 pins? Will it still work?

by

Buy a new connector off ebay providing you still have all four pads remaining on the board, if not forget the connector and wire the wires directly to the pads, shielding with kapton tape unless you good at finding the jump and using a fine wire.

David, it all will depend on what the connector looks like and what the traces on the logic board look like. The one thing that will need to be done for sure, it will have to be soldered back to the logic board. Not an easy job and it will need to be done with the right tools and the right skilled person.

All the unibody MB/MBP use the same 4 pins black fan connector. Not easy to solder back this connector to the logic board. You can't use a hot air station, the connector would melt. If there's still solder on the logic board 4 pads you can apply flux on them and add a little solder to each one then glue back the connector in place and with a fine tip solder iron resolder each pin. You can also solder the 4 fan wires directly to the logic board pads. My advice would be to find a tech that could do the job for you.

Mine has four pins but then two rear corner pins. Are those functional and need soldering as well?

This is a pretty easy fix if you have soldering skills. If not, stay away and find someone to solder it for you.

Hey quick question: I went for the attempt on soldering it myself. I have a little experience soldering, but not with computers. The fan runs, BUT doesn't stop running when it is on. Did I screw up? (NOTE: there is no OS currently installed on the 'puter; would that affect it?)

by

It's normal that the fan runs when the computer is powered on (when you start the machine with the power button) no matter if you have an OS installed or not and the fan will run until you power off the computer . The fan should not run when the computer is powered off even with the AC adapter connected to it.

by

I did this with no prior soldering experience. If you learn about soldering via youtube videos, buy the right supplies, act slowly, steadily, and carefully, you can accomplish this fix. (Despite it seeming quite difficult and impossible) - Scroll down to read how I did it.

Success! If you are a n00b or have never soldered, read this!

I have never soldered before, but after accidentally popping off the speaker and subwoofer connection (almost identical to the fan connector) I needed to fix it.

Notes: You will need a fine tipped soldering iron.

I don't have "helping hands" so I placed the connector where I needed it, then used thin long strips of electrical tape to hold it in place during soldering. (running from some of the connection cables to the top of the fan)

Someone posted that if you don't have the right size solder you should use flecks chipped off of the solder you do have. I did this. I made tiny tiny shavings, placed them, and then soldered. This alone didn't work.

I had to go back in and hold the solder / iron near the pin (not touching), I put some solder on the iron, then carefully tapped the iron to the pin. The solder jumped to the pin just fine and it worked! Because I only soldered the front four pins, I cut a tiny strip of electrical tape and used my spudger to stick it to the inside back of the connector running onto the logic board. Now that sucker is locked in and perfect. Breathe, be careful, and good luck! (watch some how-to-solder vids on youtube to build confidence)

Can I ask what soldering iron you used? I'm going to be attempting this same repair but I'm having trouble finding an iron with a fine tip.

You don't HAVE to solder it. I just used a little tip of instant adhesive (superglue) and everything is working for over 2 years now. Just use a really tiny tip of glue and be sure to only use the adhesive on the non metal parts of the socket and the logic board. The glue I would recommend is made of cyanoacrylate and has a super thin surface once dried. If you are lucky, the connectors are hold together enough so that the power can run through again. Be VERY careful with this glue because it dries almost instantly and is extremely sticky. Don't spill it on your fingers or other parts of your body.

"If you are lucky," what happens if not? How will your "fix" work for case where one is not so lucky?

Recommending random people to try soldering is much more helpful, I understand. Well not much will happen if it doesn't work, you can pull the socket back from the logic board with a spudger, remove the glue and bring it to someone who is able to solder it for you. Considering the amount of adhesive used in Apple's devices, this trick isn't so far-fetched. And as you also said, it depends on how the connectors look. In my case the socket almost held in place by itself, when I tried to put it back, so I just tried, and it worked.

by

I totally get what you are saying, but it can open up way more issues. Ever tried to remove cyanoacrylate adhesive from a multilayer board? It is easily possible to tear the traces and shorten traces by trying to remove it. If you want to suggest using adhesive, go all the way. Remove the end from the fan and "glue" the wires to the solder pads. At least that way you might only ruin the pads but not the board.

by

Yeah, that might be true. But I think amateurish soldering plays in the same league. I wouldn't recommend to use the glue on the pads, or traces, or any important part of the socket or the board. Just on the plastic of the socket and the "black parts" of the logic board, I guess you know what I mean. And only a micro tiny tip on each side, with a needle or something. That way if needed the glue is easily removed with a pointed instrument or a scalpel, I know that, because I did it ^^

Yeah, that socket is a real a****le, and I'm sure it wouldn't brake off so often, if Apple had used some stronger adhesive or something to join the socket with the board in the first place, but the only connection it seems to have are the connectors themselves. Please correct me if I'm wrong but this thing just smells like a predetermined breaking point.

My Computer is a 2010 era 17" MB Pro and the connectors for the fans onto the mother board are exceedingly friable and came off almost just with touching the wires. I do not know if that is common or not but I was not working anything hard at all and they just separated ! My vote is to very carefully solder the wires directly onto the board and ditch the poorly designed connector.

Yeah, the connector on my board came off with very little force. Accidentally tried removing the fan wires by pulling horizontally rather than vertically. The entire socket came off the board, with the connector still in it. One of the small corners with the little metal tab broke off on its own as well. I don't think those tiny corner tabs do anything, other than help keep it to the board. Hopefully when my replacement socket and fan arrive, I will be able to solder it on with little hassle. If I struggle with the connector, I'll just be soldering the wires directly to the pads.

I would suggest just gluing it on. I broke off my MBP fan connector--those things are effing fragile--but as I knew that soldering was beyond my skills, I just tried glue and it worked. It was some household glue, nothing special. It seems to work so far. Just make sure that all the metal parts at both ends of the connector touch their counterparts on the board and that the connector is tightly attached to the board.
