Cleaning Dell Inspiron 5100 Cooling Fan Part 3

[ad#Clean Fan]

Recently my notebook has been giving me a lot of trouble. When I run too may applications, or sometimes when I’m watching DivX shows, the CPU will suddenly slow down. I can feel hot air coming out of the exhaust port When I place my hand there.

This is a continuation of a series of posts that document how I cleaned the cooling fan.

Step 9: Clean the fan with a damp cotton bud, cleaning all the accumulated dust.

Step 10: Clean the cooling block as well. The layer of accumulated dust actually becomes an insulation layer that prevents heat from dissipating effectively. You have to reach all the way to the back to clean the grill too, since a lot of dust gathers there are blocks the exhaust air flow.

Step 11: This is how a clean grill should look like (I hope!)

Step 12: Make sure the fan housing is dust free as well

Step 13: Look around the rest of the notebook and clean any hair, dust or food crumbs.

Step 14: Eww, look at all the dust!

Step 15: Put everything back, by reversing steps 8 to 2.

Done! Turn on your notebook to make sure it still works. Your notebook will run at a lower temperature now.

    Stop the presses! 🙂


    First, thank you for your time and consideration!

    I found a solution in the comments!!!

    ?EURoeThere is a really easy solution if you loose video after reseating the CPU. […] there is a small turn screw on the left hand side of where the CPU sits. If you look closely, there are small LOCK and UNLOCK icons on either side of the space where you would turn. After seating the CPU, simply turn the little notch to UNLOCK then back to LOCK, screw your heat sink and fan back in, replace all screws and parts.?EUR?

    I immediately opened it up, ?EURoeunlocked?EUR? that screw, undid the screws-with-springs, removed / reseated the CPU (it?EUR(TM)s attached the bottom side of the screws-with-springs big ol?EUR(TM) case) and ?EURoelocked?EUR? that little screw. I reassembled everything and fired it up. BAM! It worked!!!

    Thank You!!!

    Adino: Awesome! Thanks for sharing the solution!

  2. Thanks, big time it was really stuffed with dirt!! It now runs smoothly…

    TYVM, Joris

    Adino: No problem Joris!
