My MacBook Pro is overheating

Hi Paulina,

I had a major overheating problem and by installing SMCfancontrol I was able to increase the fan speed manually and it solve all of the heat problems.

You can get it here.

Easy to install and use.

Google a program called "smc fan control", it lets you set your fan to maximum

So I have smc fan control running on my mac... but my computer is currently 170 Degrees F... the fan is also running at 6204 rpm and the temp is not going down. The only application I have open is Google Chrome. ._.

hey

I have the same problem and resolved to the following conclusions

So for everyone who is fed up with apple ignoring the overheating computers, its a hardware problem not a software problem. ive tried snow lepard, lion, mountain lion, Ubuntu(linux), and windows. All of those had the same problem...idling(nothing open after 20min of being on with nothing open in the interim period) around 60 degrees celcius. ive tried 3rd party fan controllers on the the listed OSes...all resulting in the listed temperature. I did take the back off the laptop and run it that way to see if its an airflow problem(dust build up) and it was clean. While it was on like this i put my finger on the outlet of the 2 fans and i felt that they both put out hot air but one being hotter than the other(this was while it was running ubuntu and at forced max RPM of fans). I did some research and found that the fan that was putting out heat was my CPU which in turn heated the airflow for the rest of the computer. With laptops, this is a common problem, you get one hot part that acts like a heater for the rest. The only fix ive found is to turn off the laptop, close the lid, throw it in a drawer, and build my own computer....makes it 100x easier to diagnose what the real problem is. Unfortunatly the only way to fix a hardware problem with most laptops is to replace the motherboard(logic board in apple world). In desktops you can normally replace individual parts on the motherbaord because they arnt soldered on. In most laptops(all macs) in order to replace the CPU, GPU or motherboard, you have to replace the whole thing(the logic board contains the whole shabang). however you can replace the HDD, fans, disk drive, and memory independantly.

Also on a side note, for those who want to go back to OS that came with the computer to see if it fixes the problem, here are some instructions

prerequisites: retail DVD of the OS you want to install

0. backup data

1. wipe hard drive(necessery to downgrade...thanks apple....remember to backup data)

2. insert DVD and boot the mac

3. follow install instructions(normally you have to hold a button to boot into the disk but since it works through a heirarchy (user input(holding D for diagnostics, C for CD, etc)>HDD>Disk>other bootable media), the bootable is the only option.

follow at your own risk.....hopefully this helps someone

If blocked fan vents and SMC resets don't fix it, it might be software related.

If you go to Console utility you might find the culprit. You might have to disable "system integrity protection" in El Cap. Mine was a location tracker utility that was constantly failing and respawning and overtaxing the system. Look for "launch.apple.xpc.launchd" and what comes after it.
