    So I finally figured out that you need this thinner copper shim:
    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260506078628
    for the 8400GS dedicated GPU in the dv2700se notebooks and not the nice big shim:
    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330373023260
    that works for NVIDIA AMD integrated GPUs (same thickness as a copper penny). If you use the thicker shim your CPU won't make good contact with the heatsink and you'll have thermal throttling aplenty. Unfortunately I didn't figure that out until after I left eBay feedback. Oops.

    Anyhow, using IntelBurnTest and HWMonitor, I'm seeing max CPU temps of 84C and max GPU temps of 76C. This seems a little high to me, certainly higher than I saw from the last AMD notebook I repaired, but the 45nm 2.5GHz T9300 is a high-end chip and the 8400GS surely puts out more heat than a GeForce 6150. I think that the weak HP cooling system is getting overloaded more than anything I did? IntelBurnTest is a bit more extreme than real-world use. The CPU and GPU are currently idling at 38C and 52C, respectively.

    high-purity copper sheeting can usually be bought as scrap at your local steel/metal supply yard. I've bought useful scraps of copper sheeting from foil thickness up to 1/4" thick for not much more than the per-ounce cost of the metal.
