Sorry, i have a CPU: Intel(R) Pentium(R) 4 CPU 2.66GHz (2672.74-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf29 Stepping = 9 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x4400<CNXT-ID,xTPR> So coretemp is not for me. While experimenting, i noticed the 1st and 3rd temperatures from mbmon to be updated in a fashion that seems natural. [achix@panix ~]% mbmon Temp.= 41.0, 201.0, 42.0; Rot.= 3443, 0, 0 Vcore = 1.50, 1.81; Volt. = 3.30, 5.08, 11.43, -11.74, -1.69 I started to trust mbmon, and i think the 1st temp must be motherboard, while the 3rd CPU, and indeed the first value varies betaeen 41-42 degrees, and the third value from 39, (~ 100% idle) to 45 (0% idle). So i assume the above must be right. Yesterday i had mbmon -t > mbmon.out running all night and the highest CPU temp was at 46 deg C, while highest MB temp was at 43 deg Celsius (if the previous assumptions about the interpretation of the output of mbmon are correct). Both high temps happened while running periodic daily at 03:00 (which increased my trust in those). All that, was after i blew the box/case inside and closed the case. If i trust those numbers and their interpretation then i must not have a temperature problem (anymore). Lets see how the machine behaves. There is always the other usual suspect from the memory department :) -- Achilleas Mantzios
