![]() Set it up to provide (still quiet) minimum fan speeds of 2200 rpm for the HD and 2800 rpm for the CPU, leave the Optical Drive fan at 600 rpm to minimize dust accumulation (or just tweak it up if/when you will be using it much) The correct and ideal simplest way to permanently fix your overheating 24" Imac (iMac6.1 iCore 2 Duo at least, and several other models) requires two fixes.įirst download and install smcFanControl 2.2.2. There is an air pocket there caused by the vacuum back-pressure of the internal fans, which are all trying to suck air in through limited air inlets, and blowing out the upper right side of the slot so heat just accumulates there and it just runs away The usual temperature reading there runs around 130✯ (54✬!) and often (always during malfunction or addressing error graphics lockup-freeze) exceeds a peak-hold temperature of 140✯ (60✬).Īt first I mistakenly thought forcing cooler air into the bottom might reduce this but it does not. To verify this, I installed a small temperature probe in the back top left hand (from the front) side of the back air exhaust slot (right side viewed from rear) around 20 cm (9") from edge. This top left hot air pocket-trap seems to be due to negative cabinet air pressure interfering with natural heat convection on the left side heat collects there but just can't get out! The fans are part of the problem and just don't help at all. (The rear-viewed 'right' of the top air exhaust slot). I observed that the upper left hand corner of the iMac has some sort of an air pocket that traps extreme heat from the graphics card there. I use mine to run a 54" Bravia HDTV as the extended desktop and use EyeTV and noticed numerous graphics errors lines, and failures to refresh the screen during overheating bouts. ![]() It unfortunately began to misbehave again shortly thereafter. If you find it then kill the rogue process as explained before.My iMac killed its hard drive the second year of use and then the entire screen/graphics card and logic board had to be replaced at the three year mark. $ ps -ef | grep -i fanĥ01 45716 254 0 2:44pm ? 0:00.38 /Users/dave/Downloads/firefox/smcfancontrol_2_4/smcFanControl.app/Contents/MacOS/smcFanControl If you have this problem you can try to find and kill the process "smcFanControl" instead. Note that for smcFanControl you got "ERROR TC0F" instead of "ERROR TH0P". I also try to run the current version of another fan controll utility called smcFanControl (version is 2.4) and it seem to not work in Maverics (no window) but it produce near the same message in Console: 15/11/13 14:19:35,000 kernel: SMC::smcReadKeyAction ERROR TC0F kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff802af9b000 Procedure to check & eliminate smcFanControl WARNING: if you replicate this procedure replace PidNumber with the PID you get from ps -ef To eliminate it : $ cd /Library/StartupItems/Īnd then kill the daemon: $ sudo kill PidNumber This tell you that you really have FanControlDaemon running as pid 145 as PidNumber ![]() Open terminal and search for FanControl: $ ps -ef | grep -i fanĠ 145 1 0 Gio12am ? 3:58.07 /Library/StartupItems/FanControlDaemon/FanControlDaemon run Procedure to check & eliminate FanControl NOTE: this problem is similar but not equal to this one Kernel SMC::smcReadKeyAction error The other one is for another version of OSX. You can verify if you have them installed and eliminate if needed. To my knowledge there are two possible candidates (FanControl & smcFanControl but there may be more that have the same problem). The culprit can be a fan controll program you may have previously installed.
