    Hello. Nice website. It’s used as a guide in the IT department of Princeton University.
    Looking for a replacement Heat Sink Fan assembly for a old Sony Viao Model PCG-7312L
    VPCEB3AFM SN = 27528433 3015900 Service Tag = C606MZM2

    Since Sony doesn’t make computers anymore, aside from eBay, might you have a site suggestion for obtaining parts for Sony’s? Thank you very much.

      @ Ted H.
      I think this one from Amazon will work:
      Also, you can try searching by the fan model: “Sunon GC057514VH-A”
      Compare the picture with your fan and if it looks identical, most likely it will work.
      I don’t know any good supplier for Sony parts.
