The TDP is somewhat higher than the Ivy and he is under load even warmer - but this is due to the FIVR perfectly normal and even logical - while fuel consumption decreases under full and partial load. The second reason why Haswell gets warmer is that Intel with the linking no longer soldered the heatspreader but only (for cost reasons) with (inferior) WLP.
The standard VCore is clearly too high dimensioned I lowered the Xeon to -0.100 V in VCore - now he is even under Prime95 with AVX well below 60 ° at inaudible fan speed.
The microcode 0x7 the Xeon was still in Turbo overclocking to 3.7 GHz on all 4 cores (Multi 37). Thus, the Xeon is of the good value for terrific (CB multicore nearly 8.2 points), unless you want to overclock.
The microcode 0x9 Intel has however the Turbo overclocking locked and he is now working on all 4Cores only with 3.5GHz.
It costs an average of 5% performance - the e3-1230v3 is still low, however there is for such audacity not 5 star more.
