The other two -128 are expected, as they are the thermal sensors for the secondary battery. There is also one less sensor than I'd expect. > Windows, and I'm beginning to get the feeling that there is actually a > cooling problem with the hardware. This must be at least the third complain I come across of a X60 which boils the CPU. The standard fix from Lenovo is a planar card swap (motherboard swap). Since this *does* mean they replace the thermal compounds, and a full reassembly of the heat pipes, it might be that just fixing the thermal coupling between cooling assembly and the CPU might do it. > It doesn't seem to help.

Well, at least the EC is not misbehaving, then. > What's a typical max RPM? I'm getting the impression that there's More than 4000rpm, in disengaged mode. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
