Smcfancontrol macbook pro 20118/2/2023 In fact, all you do is damage the chip carriers SMD devices as the TIM effects the capacitance and resistance of the devices so they don't work properly. TIM is designed to be just an interface between the two metal surfaces (if the chip is lidded or in laptops the bare silicon chip) it is not designed to shed heat directly, so spilling over the edge doesn't help you. I find people kill their logic boards by putting too much on! Think of it this way find the thinnest facial tissue cut it into a piece that's the exact same size as the silicon chip, now wet it so you can roll it into a tight ball thats even still more than you need by volume. O'boy load it up with a pound of TIM!! Nope! Less is more here! I ran this message in the Google search & it seems it's a system sensor issue. ' ALERT! Apple hardware test has detected an error UPDATE: I ran the Apple hardware test today. Never had a problem with the mac until a few days ago. This year of macbook tends to have these issues.Īlso to note the logic board was replaced in January & a new board was installed. That is what's leading me to think it's a GPU issue. For a example, if a play a video on quicktime player or even youtube, I notice it shuts down more abruptly. The computer runs perfect fully smooth and as normal.Ī detail to note is that playing any type of video makes the system turn off faster. To clarify the overheating & shutting down are the only issues. I did that successfully but the system is still shutting down. On recommendation online, I decided to apply new thermal paste to the heat sink 2 days ago. The temperature of my system is a normal range based on what I read in the forums. I hear the fan & can feel it but it has no effect on the CPU. I even ran my system with no applications running & ran into the same issues. The first action I took to find a solution was to check the activity monitor to see the CPU load. I wait for the system to cool down & restart but the problem persist. Then it shuts off or the screen goes black & brings me back to login window after 2-5 minutes (like the Mac went to sleep). My system becomes HOT TO TOUCH (on the left side & backside) 5-15 minutes after startup. not crashing the whole system), or keep their fans running more aggressively when the CPU + GPU activities picks up in a hungry.I have a 2011 15" MacBook Pro A1286. Apple needs to figure out either how to gracefully pause while the CPU hit that limits (i.e. Intel lists a Tjunc of 100 deg C as their temperature limit. When you have a 45W CPU plus a 30W GPU, plus 13 W of just turning the machine on, then add in WiFi and HDD, you got one hot system. The fan is obviously not running aggressively enough. I think a firmwire update to the fan control unit is in definitely needed. I kept an eye on my Kill a Watt meter and it pegs near 85 W (battery fully charged). I have crashed my new laptop 6 times already this evening, all due to this issue. When the CPU Temperature Diode measurement reaches 92 deg C, the computer crashes, every time. Compiling gcc maxes out all 4 cores and then you add some graphics usage (especially on an external monitor, which kicks in the AMD 6750M chip), the computer overheats. As it turns out that's a very bad combo for this laptop. I have been trying to compile/install gcc and watch some HD youtube clips at the same time. I just received my Core i7 2.2 GHz Quad Core 15 inch laptop today.
