No sensors for iMac12,1 after update

[Datisit]

Sorry for the late reply, the sensors seem to be recognised sometimes and sometimes not. At the moment, the CPU sensor is not being seen by the OSX or the W7 client. This causes the fan to run at full speed.

Thanks,

Hi again,

So as far as I can work out, every time I restart the computer, into OS X or W7, different sensors are recognised by MFC. Sometimes many, sometimes none, but never all of them. Do you think it may be a problem with a physical connection inside the computer?

thanks,
Datisit
