Sorry, i have a=20
CPU: Intel(R) Pentium(R) 4 CPU 2.66GHz (2672.74-MHz 686-class CPU)
  Origin =3D "GenuineIntel"  Id =3D 0xf29  Stepping =3D 9
  Features=3D0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PG=
E,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Features2=3D0x4400<CNXT-ID,xTPR>
So coretemp is not for me.
While experimenting, i noticed the 1st and 3rd temperatures from mbmon to b=
e updated in a fashion that seems
natural.=20
[achix@panix ~]% mbmon
Temp.=3D 41.0, 201.0, 42.0; Rot.=3D 3443,    0,    0
Vcore =3D 1.50, 1.81; Volt. =3D 3.30, 5.08, 11.43, -11.74, -1.69

I started to trust mbmon, and i think the 1st temp must be motherboard, whi=
le the 3rd CPU,
and indeed the first value varies betaeen 41-42 degrees, and the third valu=
e 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 ab=
out the interpretation of the=20
output of mbmon are correct).
Both high temps happened while running periodic daily at 03:00 (which incre=
ased 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 te=
mperature problem (anymore).
Lets see how the machine behaves.
There is always the other usual suspect from the memory department :)
