tommix1968 Posted June 15, 2011 Share Posted June 15, 2011 Hi @ all, i have installed 10.7 and my CPU-Fan runs with 100%. On my 10.6.x this no Problem. Anyone an idea how i could fix this? My Hardware: GA-Ep43 DS3L Intel QuadCore 8 GB GeForce 9600GT ASUS WLan Link to comment Share on other sites More sharing options...
Ninja82 Posted June 15, 2011 Share Posted June 15, 2011 I might be mistaken but Mac OS X does not have a Fan Control system. So the best way to set it is to go to Bios and set the Smart Fan system I thing. I do not quite remember the name exactly (sorry). There you can set how fast the fan should run. If you set the fan to the 20% for example then the Bios increases the fan speed if the CPU gets hotter and once the CPU gets cooler fan speed goes down to the appointed speed (that 20%).

Hi, Thanks for reply. Will monitor this strange behavior... Link to comment Share on other sites More sharing options...
kokousic Posted June 22, 2011 Share Posted June 22, 2011 It is called cpu fan control. Enabling it provides better acoustics but disabling it provides low temperature. I prefer to disable it so that my processor does not heat up. Link to comment Share on other sites More sharing options...
miketh Posted July 6, 2011 Share Posted July 6, 2011 I just had the same problem and fixed it, by reseting the PRAM. instructions below... Resetting PRAM and NVRAM 1 Shut down the computer. 2 Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4. 3 Turn on the computer. Wait about 30 seconds. 4 Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears. Hold the keys down until the computer restarts and you hear the startup sound for the second time. then release the keys.

MTWomg Posted July 6, 2011 Share Posted July 6, 2011 I'm not having that problem. I also am using some kexts (ACPIMonitor/IntelCPUMonitor/SuperIOFamily) to allow me to see the temperature of the CPU/Board in iStat Menus, everything is normal.

smartie77 Posted July 12, 2011 Share Posted July 12, 2011 can also be the Graphics Cards Fan .. OSX controls GPU fan by asking Computer which MacModel it is. According to the answer OSX activates power modes for the gnu that the MacModel has inside. Have a look inside the plist.info of /S/L/E/AppleGraphicSPowermanagement.kext -- you must set via SMBIOS in /Extra the Mac Model to one there in the kext. For example : I have ATI4650mobility with device id 1002 (ATI ) 9480 ( 46xx family ). The iMac 9,1 and 10,1 have also this family card ( 4670mobility exactly ), so Kext has entry for iMac 9,1 and lists configuration options how OSX should power on/off the card if Mac=iMac9,1 .. ATI 4650/70 has 3 settings - one for idle, one for medium and one for full fan ( videos/3d) -- this setting is only going active if my hack book imitates such an iMac Model. if I set it to Macbook the card will run at full power all the time, cause Macbook has no ATi card of my family. hard to explain in non-technical way. SMBIOS is very essential what works and what not.. YOu need to google which mac has your hardware .. then set Hackintosh to that Model. smbios.plist is only a textfile, just play with it, but must reboot to see a change. then notice what works and what not.
