The coretemp kernel module reports 25°C on my PC when idle, and 34°C after having performed some computations (lmbench2). This looks normal. This test has been performed with a vanilla 2.6.25 kernel and a Core 2 Duo E6750 CPU (Asus motherboard). The 2.6.22 and 2.6.24 kernels report an incorrect temperature on the same system however (10°C). So there is either an issue with the patches that have been applied to your kernel or the behavior of the coretemp module for the 6600 and E6750 CPU's is different. Can you repeat the test with a vanilla 2.6.25 kernel ? (Added Rudolf Marek in CC, the coretemp author.) Bart.
