The temperature drifts that I've seen are much smaller than the basic calibration. On the other hand recent Linux kernels have screwed up the basic calibration on startup so rebooting a machine is much worse than a temperature change. (If they have fixed it recently, I haven't seen any announcement. You can fix it by hacking a constant into your kernel.) -- These are my opinions, not necessarily my employer's.
