Replacement of Fujitsu Lifebook N6420 cooling fan


Note this procedure is specific to the N6420, but may work on other N series Fujitsu notebooks. I generated this solution by a step-by-step process on my N6420.

Procedure for replacing (two) cooling fans on Fujitsu Lifebook N6420. This procedure was required because of fan bearing noise, indicating potential failure of the fan in the future and the noise was very annoying. I performed this procedure after about a year of bearing noise and after not finding any reliable procedure on the web. Fujitsu offered to replace the fans for $230 - far more than the laptop is worth at this point. Below is the correct procedure for the N6420 and specific to that machine.


You will need to purchase two cooling fans Toshiba Part Number S6055AM05. Be sure and purchase the ones with metal backing on one side of the fan. You can find them on eBay for about $10, but beware of what you buy. Recommend you purchase new OEM fans and not refurbished fans as they may not come with the thin metal heat transfer plate provided on the OEM fans. Some of the knock-off and refurbished fans do not include the metal backing, heat transfer shield. You will not need thermal paste.


Note: All of the other instructions on the web I found for the N6420 were incorrect and seemed to be lifted off some other notebook. I actually performed these instructions and made sure they are accurate.


Note: While you wait for the new fans .... and you must use your N6420, but want to buy yourself a little time before the fan(s) totally die ... you can try this procedure at your own risk ... and spray a very small amount of silicone lubricant between the fan electronics and the spindle - this area is easy to indentify if you hold one of the fans on its edge. The use high pressure air spray to blow out any grit, dust and silicone overspray - wipe each fan with a clean cloth. This little bit of lubrication and cleaning made the bearing noise go away. Both fans are spinning up ... but, I ordered new fans anyway to make sure the notebook would have adequate cooling and to preclude the old fans from going bad and causing catastrophic overheating.


Here is the fan R&R procedure itself:

- Shut off the notebook and disconnect all peripherals

- Remove cover to RAM (optional)

- Remove Battery

- Remove HD Cover and HD(s) (I have two - some may only have one)

- Remove 15 retaining screws

- CAREFULLY - Remove base/bottom notebook cover, take care on the side with the PCMCIA slot, USB port and sound ports

- Note orientation of the two fans so you can replace them the same way

- Now remove the two old fans (two screws)

- Install the two new fans

- Replace two screws under HDs

- Replace two screws under battery

- Reinstall the base cover - take care on the side with the PCMCIA slot, USB port and sound ports

- Replace the remaining base cover retaining screws

- Replace HD cover and its retaining screws

- Replace RAM Cover

- Make sure you have no/zero retaining screws left (all 15 screws and the HD cover screw are identical)

- Restart Notebook and get back to business

Fujitsu N6420 upgraded to Windows 7 Professional. Ran fine for a month or so until it hung in middle of automatic Windows update. Now can not boot from hard drive or CD--gets to Windows logo splash screen...


If you still have the install disk you can put that in, hold F12 as the computer is booting up, and choose to boot from CD. The setup disk has a repair option that might fix the problem.
