Hello! I have 2 processor 6-core xeon 3.33GHz x5680,but while I do not have a dual-processor mac pro and unsure whether enough standard cooling, because the online Apple oficial model of cpu maximum is two 12 cores xeon x5670 2.93. I am sure that the processors will work, but am not sure whether or not due to overheating CPU Throttling at full load all the cores, because the maximum-allowable temperature of the processor intel xeon ~ 70 degrees Celsius. At temperatures above 70 C, to slow down the processor speed that could make it slower than the official x5670 2.93GHz, is this true? Throttling - temperature should significantly exceed 70 ° C, for example 80C - 90C and the standard cooling enough to eliminate Throttling for two xeon x5680 3.33Ghz? How many of you on this forum has already established two processors x5680 in your mac pro? There is a formal mac pro 6-core 1 cpu 3.33ghz, but cooling it more powerful. Why in 6-core model cooling more than in 12 core model?: To put on a mac pro 4.1 is it necessary to remove the covers from the CPU? Thank you so much!
