cpu temp.

tjena , vilken ska man lita på när man ska kolla temp på cpu ? det som visas i bios eller i core temp?

Kör HWmonitor.

tankade den nu och den visade samma som core temp ungefär , (1-2 grader skillnad ) men den visar också 10 rpm i fläkt hastighet ?

Om du kör standard-kylaren eller någon annan med PWM så kan det ge udda siffror i en del olika mätprogram, inget att haka upp sig på så länge temperaturerna ser vettiga ut.

En bra förklaring saxad från SpeedFan's FAQ:
Fan speed control is achieved by accessing some features available in some hardware monitor chip or some other special hardware. These chips might be able to controls fan speeds. They usually do this by using PWM output. A PWM digital ouput is a digital signal that alternates some levels very fast, thus simulating some intermediate average level. The net result is a perceived average voltage lower than the usual one. Please note that some chips (very few of them) are able to lower the voltage without PWM simulation.
The fans, on the other hand, can report their speeds (RPM) by using some internal sensors that report how often some current flows between two plates. Fans are built assuming nominal voltages and a continuous signal. When voltages are lowered or modulated through PWM, some fans are no longer able to properly trigger when those plates face each other and resulting fan speeds may show odd values.
