Replace Fan – Lenovo Yoga 2 Pro

A fan in my sons 2yr old Lenovo Yoga 2 Pro was making very loud grinding noises. We dissembled to check for dust and clogged vents but no dice, sounded like the bearings were going out.  Next step was to replace the fan and we didn’t want to spend a dime on this out of warranty (many issues since day one) laptop so it’s time for some DIY!

Steps to replace one or both fans

  1. Turn laptop upside down – place lid on towel to prevent scratching

  4. Disconnect the battery from the motherboard – far right ribbon with large connector
  5. Remove the flexible PCB ribbon  – horizontal ribbon at top left of motherboard
  6. Do not – disconnect the blue ribbons (you can but tricky to reconnect)
  7. Disconnect the fan cable – use the blade of a small flathead screw driver
  8. Remove the two small phillips screws that hold the fan in place
  9. Remove the mover board screw at the top left corner of the board
  10. Gently title back the motherboard until you can easily remove the fan

  1. @Lee Fram did you end up replacing both fans, or just one? I’m in the same boat: my problem is with the fan that is next to the power port; the sounds it has been making are truly awful.

  2. is there any good way to tell which orientation for the connector to plug the fans back in? It seems like it can go either way.

  3. This is very helpful, thanks!

    Is it possible to just replace one of the two fans, without removing the motherboard, etc.? I believe it’s just my right side fan that is making grinding noises. I bought the replacement fans, and it looks like I could remove the right side one and maybe just replace that a lot more simply? It’s attached to the assembly by some black adhesive tape type of stuff, apparently.

    Thanks again!
