Thinkpad T60 overheating

I got a used Lenovo Thinkpad T60 series 2007 and installed Arch.  Every 12 - 20 minutes, it shuts itself off. Looking at the logs, I see:

May 30 21:33:40 thinkpad kernel: thermal thermal_zone0: critical temperature reached(128 C),shutting down

The output of `sensors` shows "temp4" is always the highest (and steadily climbing) and I haven't seen any of the others above 60 C, so I assume that's the one. thinkwiki.org says this is the GPU.
When I had opened the case to check the fan and heatsinks earlier, I noticed the GPU (AMD Mobility Radeon X1400) has no heatsink at all. There is room for one.
Is this lack of GPU heatsink usual for this laptop? What can I do about the overheating? Would it work to simply stick on a piece of metal for a heatsink with thermal paste, using the heat pipe from the CPU that passes over to hold it down or something?

Re: Thinkpad T60 overheating

The previous owner put the wrong heatsink+fan assembly in here, for some reason. I'm waiting for the right one to come in the mail. And someone else will be convinced to pay for it.
