CPU-Z and SpeedFan will be used to Calibrate Tcase at Idle. Prime95 will be used in addition to CPU-Z and SpeedFan to Calibrate Tjunction at Load. SpeedFan will then be used to permanently monitor temperatures.
Use the following links to download and install these utilities:
* CPU-Z 1.44.2: http://www.cpuid.com/cpuz.php
* Prime95 25.6: http://www.majorgeek...me95_d4363.html
* SpeedFan Beta 4.34 displays Tcase and Tjunction: http://www.almico.com/speedfan.php
Note 1: Prime95 - When run for the first time, it is necessary to click on Advanced, then click on Round off checking so that errors caused by instabilities will be flagged as they occur. Prime95 will expose insufficient CPU cooling and computer case cooling, or excessive Vcore and overclock. At no other time will a CPU be as heavily loaded, or display higher temperatures, even when OC'd during worst-case loads such as gaming or video editing. Prime95 can be used with SpeedFan to observe CPU temps, while stress testing for system stability. During single threaded gaming and applications, Core 0 typically carries heavier loads and higher temps than other Cores.
Note 2: SpeedFan - Very flexible and configurable, SpeedFan is the preferred temperature monitoring utility because Tcase and Tjunction can be Calibrated. SpeedFan detects and labels thermal sensors according to various motherboard, chipset and super I/O chip configurations, so the label for Tcase can be CPU, Temp 1, Temp 2, or Temp 3. Even if Tcase is labeled as CPU, it is still necessary to confirm the identity of Tcase prior to performing Calibrations.
* Repeatedly start and stop Prime95 Small FFT`s at 15 second intervals, while observing which SpeedFan temperature scales with an Idle to Load Delta similar to the Cores. This will identify the label corresponding to Tcase. Labels can later be renamed using the Configure button. See Section 11.
If a temperature shows a flame icon, this indicates alarm limits which require adjustment. Use the Configure button to set CPU and Core temp alarms to Warm Scale. If a temperature shows Aux 127, this is simply an unassigned input which can be disabled using the Configure button. See Section 11.
Note 3: TAT - The software utility (TAT) Thermal Analysis Tool at maximum settings will simulate 100% Thermal Load, which would equal Prime95 Small FFT`s at 114% Workload ~ 5c hotter. This provides the most extreme testing available for CPU and system cooling efficiency. Since TAT is coded to measure Notebook temps, it identifies a C2D as Pentium M. As Notebooks have no Integrated Heat Spreader, thermal scaling differs from desktop CPU`s, so TAT indicates ~ 2c lower, and depending on Variables, temps may be Offset by more than 15c. It is therefore recommended that TAT be used for extreme thermal testing only, and temps regarded as unreliable.
