Does Acer sell replacement heat sinks for the Aspire 7745G laptop?

Does Acer sell replacement heat sinks for the Aspire 7745G laptop? I can find any number of aftermarket and reconditioned parts distributors online. Is there any chance that Acer will actually let you order a replacement part directly? The "replacement part" store is obviously for anyone who isn't ready to "crack the case" and do their own repairs. Does Acer even acknowledge that there are customers out there who can do their own after-warranty repairs?

Also, let me add that this "fork over the dough, or no support after warranty" is ***. I definitely won't be buying an Acer in the near future, and I won't be letting any of my customers buy one, or even take one if it's free.
