In this guide I will help you to remove and replace the cooling fan in a Dell Latitude D600 laptop. The cooling fan in this model is buried deep inside the laptop under the top cover. Also you can use this guide for cleaning the cooling module and removing dust from the heat sink and fan.
If your laptops shuts down on its own without any warning, most likely it happens because of overheating. Make sure the cooling fan works and the heat sink is not clogged with dust. Replace the fan if it failed or clean the heat sink if it’s clogged.
Before you start, turn off the laptop, unplug the AC adapter and remove the battery.
When you are replacing the cooling fan, it is not necessary to remove memory, hard drive, wireless card or optical drive. I did that only because I was upgrading the laptop.
STEP 1.
Remove all marked screws from the bottom of the laptop.
STEP 2.
Lift up the switch cover with a small screwdriver. Continue removing the cover with your fingers.
STEP 3.
When the switch cover is removed you can access two screws securing the keyboard. Remove these screws.
STEP 4.
Lift up the keyboard and access the cable. Disconnect the keyboard cable from the motherboard.
Search for new keyboards here.
STEP 5.
Remove three (red) screws securing display hinges.
Remove one (yellow) screw securing the video cable ground.
Disconnect the video cable connector from the motherboard.
STEP 6.
Remove and replace the LCD assembly.
Take a look at this guide for the LCD screen removal instructions.
STEP 7.
Remove three screws securing the top cover.
Disconnect the touchpad cable from the motherboard.
STEP 8.
Start separating the top cover from the base with your fingers.
STEP 9.
Remove the top cover assembly.
STEP 10.
Now you can clean the cooling module (fan and heat sink) using compressed air. In order to replace the fan, continue laptop disassembly.
Loosen four screws securing the heat sink.
Lift up and remove the heat sink.
STEP 11.
Remove two screws securing the cooling fan.
Disconnect fan cable from the motherboard.
STEP 12.
Remove and replace the cooling fan with a new one. You can find a new replacement fan for Dell Latitude D600 laptop here.

Thank y ou so much for your instructional article on the removal of the cpu fan for the Dell. However, I do not believe that you were using a Dell Latittude D600. The fan for the D600 is located in the right hand corner and is working intermitantly. I removed it and it bench tested O.K. I will now have to test the supply 5 V. Any Suggestions? Thanks again for the help.

thanks for the guide, i have the same dell d600 that works fine except the fact that the heatsink fan is not working! i already cleaned up the dust from the fan and heatsink and put a thermal glue and it didn’t fix the problem, then i replaced the fan with another one that i got from a broken dell D600 and i had the same result!! so is there any thing else that could possibly cause this problem? any suggestions will be most appreciated. thanks.

kareem,
Not sure 100% but if another known good fan doesn’t work, there must be a problem with the motherboard. Apparently the motherboard cannot control the fan properly. Just a guess.

I just found this and it is quite helpful thank you.
I think is a Dell design by default. The fan will spin up when needed but not run all the time. I have found some software via a google search that allows the fan to run at full speed all the time, so far it has dropped my temp by 10 degrees and counting.

Great tutorial. It was of great help to me. I have just cleansed my laptop’s fan and it now runs much more quiet.
THANK YOU.

Very useful, fan is now replaced, but I ran into another problem. The display hinges are now locked so that the display is in the vertical position. Any hints gratefully received
Thanks, Jerry
