roudy-s :
My i7 880 is running the prime95 stress test with small ffts for about 10 minutes till now what do you think of the temperature are they good?
The max temp is 57 core0 54 core1 54 core2 56 core3.

Your Core temperatures are barely warm.
Intel Desktop processors have temperatures for each "Core" and a temperature for the entire "CPU". Core temperatures are measured at the heat sources near the transistor "Junctions" inside each of the Cores where temperatures are highest. CPU temperature is instead a single measurement centered on the external surface of the CPU's "Case" or "Integrated Heat Spreader" where the cooler is seated.
Core temperature is considerably higher than CPU temperature due to differences in the proximity of sensors to heat sources.
Your i7 880 has two Thermal Specifications. For Core temperature it's "Tjunction" which is also called "Tj Max" (
Temperature
Junction
Maximum) or “Throttle” temperature. For CPU temperature it's "Tcase" (
Temperature
Case) which is a
factory only temperature measurement.
The "max temp" specification that
clutchc referred to is the Tcase, which is 72°C: Product Specifications for Intel® Core™ i7-880 Processor - Intel® Core™ i7-800 and i5-700 Desktop Processor Series Thermal Specifications -

The Tj Max
Throttle temperature for your processor is 100°C: Intel® Core™ i7-800 and i5-700 Desktop Processor Series Thermal Specifications -

See page 36, Table 6.1, Note 5.
From Core 2 processors in 2006 to today’s Core i processors, Tj Max has always been the
limiting Thermal Specification;
not Tcase. Although useful for developers of cooling solutions, Tcase is the temperature on the processors Integrated Heat Spreader (IHS) ... so
Tcase is not Core temperature. Since Core temperature is higher than IHS temperature, Tcase is an irrelevant specification.
Here's the real-world operating range for Core temperature:
Core temperatures above 85°C aren't recommended.
Core temperatures below 80°C are preferred.
Core temperatures increase and decrease with Ambient temperature.
