Looks ok to me. Be sure to test your pstates with DPCIManager or AppleIntelCPUPowerManagementInfo.kext.

Upgrade my system to 10.9.5 patching the mach_kernel and works fine with -xcpm
I see that the geekbench and cinebech are higher in my macbook air 2012 than the fanless hack:
Geekbench macbook air:6583
Geekbench fanless: 6033
Cinebench macbook air: opengl 14,26 and cpu 214
Cinebench fanless: opengel 11,50 and cpu 212
There is only a difference in the GPU HD 4000, but i think isn't a PM problem: AICPUPMI: CPU P-States [ 8 9 10 11 12 13 (14) 15 16 17 18 19 20 21 22 23 24 25 26 ] iGPU P-States [ (7) 8 9 10 11 12 13 14 15 16 17 18 19 20 21 ]

Maybe a ram "problem"? The macbook air has 2 soldered ram 2x2Gb DDR3 1600 and the fanless hack has only one RAM slot with 1x4gb DDR3 1600, no dual channel (obviously).

I attach the macbook air and fanless geekbench (see the memory and stream value).

It could be just the memory. I wouldn't put too much trust in GB results. IMO, it is not a very good benchmark for understanding total real world performance (weighting of individual results is poor).

Realize it is "just a number" and just enjoy your hack.

Exactly! And thank you so much for all your help!
