odd fan speeds

Post by ruser »

I was using smcFanControl, but as it has been inactive for almost a year, I figured i'd try your fan controller.
I noticed something odd, though. If my temp goes above my maximum (currently set to 158°F) my fans go much faster than their supposed maximum (i've seen them at 7320 rpm). It stays at that speed until the temp drops to 132°F, then all of a sudden the fan speed drops back to 3556 rpm. It seems like the program is unable to spin the fans between 3500rpm and 7200rpm... thats a pretty big jump.

Here is my tech info with it running normally:
Machine:MacBookPro4,1
Fans:Left side-min{1992}curr{3419}max{5976}mode{2,TC0D,50,70}Right side-min{1992}curr{2902}max{5976}mode{2,TC0D,53,71}
TempSensors:TALP,TB0T,TC0D,TC0P,TG0D,TG0H,TG0V,TGTV,TTF0,TW0P,Th0H,Th1H,Th2H,Tm0P,Ts0P
Values:Bottom Enclosure - 29,CPU Diode - 58,CPU Proximity - 53,GPU Diode - 65,GPU Heatsink - 53,Airport Card - 43,Left Palm Rest - 35,Hitachi HTS542525K9SA00 - 33,M4-CT256M4SSD2 - 0,


And here is my tech info with it over maximum fan speed:
Machine:MacBookPro4,1
Fans:Left side-min{1992}curr{7216}max{5976}mode{2,TC0D,50,70}Right side-min{1992}curr{7261}max{5976}mode{2,TC0D,50,70}
TempSensors:TALP,TB0T,TC0D,TC0P,TG0D,TG0H,TG0V,TGTV,TTF0,TW0P,Th0H,Th1H,Th2H,Tm0P,Ts0P
Values:Bottom Enclosure - 30,CPU Diode - 80,CPU Proximity - 63,GPU Diode - 71,GPU Heatsink - 58,Airport Card - 43,Left Palm Rest - 37,Hitachi HTS542525K9SA00 - 33,M4-CT256M4SSD2 - 0,

Hi,

I'll check the issue.
But one shouldn't set both fans spinning in relation to 1 sensor (CPU Diode).
The second fan is normally for GPU

Right (GPU) and Left (CPU)

We released 1.0 beta 4 now. Problem with fan value that exceeds MAX is fixed.
