If you run Prime for an entire hour I promise your going to jump into the 70’s if you hit 65 in the first 15 mins. Try running Prime longer and watch the temps… just 1 hour, you’ll see.
grieve,
I can understand how some users might find that misleading. Allow me to clarify:
Pime95 Blend is a
fluctuating workload, which is an excellent tool for memory stability testing. Blend will cause CPU and Core temperatures to vary throughout the duration of the test.
Prime95 Blend as displayed in SpeedFan Charts:
As you've suggested, Blend begins at less than 100% workload, however, after approximately 20 minutes (not 1 hour), Blend increases the workload to
peak at 100%. Unlike Blend, Small FFT's is a
steady-state 100% workload, which is the accepted standard for thermal benchmarking and stability testing.
Prime95 Small FFT's as displayed in SpeedFan Charts:
Small FFT's will cause the processor, socket and heat sinc to reach saturation within 7 to 8 minutes, so a 10 minute test is adequate to find maximum CPU and Core temperatures. As such,
Vashek has already found his maximum CPU and Core temperatures.

(
A) Start Prime95 Small FFT's... Observe SpeedFan. Thermal saturation is typically reached within 7 to 8 minutes, so allow
10 minutes to assure that temperatures increase to
maximums..."
Additionally, the Thermal Specification shown in Intel's Processor Spec Finder -
http://processorfinder.intel.com/details.aspx?sSpec=SLB8V - is CPU temperature,
not Core temperatures, which is a very common misconception among many users.
