I installed FakeSMC on my 4,1 in order to get the GPU temperature. I am now able to get the info I want, plus the CPU temperatures / frequencies for each core. However, I lost the fan speed reading. So far, I only installed 1) FakeSMC.kext 2) IntelCPUMonitor.kext 3) RadeonMonitor.kext Is there any body know how to get back the fan speed reading? Thank you Netkas for providing us such a great tool!
