Question about Sony VAIO VGN-SZ430N/B Notebook
The laptop operates with load nois. The cooling fan makes noise and it seems that the mecahnical part needs to be repaired. The Sony serveice center asks $300 to repair it and I decided to solve the probmlem myselfe. But i can't reach the cooling fan. Could you please let me know how I can replace or clean the fan in this model.
It's not only by blowing air into the fan. 1.- Go out and buy thermal paste. Open heat sink cover (next to memory cover) only 4 screws. 2- Remove 2 screws over the processor 3- Remove heat sink completely and you will notice a hell of a lot of dust that will not be removed othewise, Blow off and blow on fan to clean also. That should resove the problem if after that you have noise and excessive heating then the fan has to be replaced. To disassemble completely go to
These instructions not necessarily match your Notebook but are pretty close to reality you should not have any problems by being patient, careful and armed with the proper tools. Hillar

Did you try blowing it out with compressed air 1st?.
