Hi everyone

My 2011 Macbook Pro is running on 6000 RPM and 78C when i'm doing literally nothing. The fan noise is really disturbing...

I'm aware that there are lots of topics on this issue but i've been reading for a while and could not locate/solve my problem. I really lack technical knowledge by the way but i will try to provide you the necessary properties.

Here's how my "About This Mac" looks like;

And here's how my "Activity Monitor" looks like;

I'm not sure if you need any other information..

My warranty coverage will end up in 5 months so i'm wondering if there is anything i could try to solve the problem before taking my mbp to an Apple Service.

Thanks for taking the time
:)

I'm not sure why, but your system is under quite heavy load, so 78 C and audible fans is just normal.

Did you try to reboot?

This problem has been going on for months.. I tried to read everything that i could but as i lack technical knowledge i'm still not sure if i did everything. But yes i did reboot couple of times and also tried resetting SMC :(
 
Can't see your activity monitor, can you provide a bigger screencap? And if you have iStat Menus, provide a screencap of all the component temperatures too if you don't mind.

I downloaded iStat Menus and here's the screencap of all the component temps

Hope these will help :)
 
Couple thoughts...have you opened up the case and blown out any dust you have in there? I have a pre-unibody so I apologize if this isn't an option.

Also, I had a similar issue and I got SMC Fan Control running and just have it start with both fans at 3000 rpm. This keeps it cool most of the time and prevents my computer from thermal runaway of getting hot with the fans maxed. I know this doesn't solve the cause, but is more of a bandaid

Your images are too small, can you not post thumbnails and post the actual sized pics. I can't see anything.

That's weird :S i'm not posting thumbnails and i'm uploading with the actual size option checked..

Actually i checked with another pc and i see large pictures in my posts :(

Haven't opened up the case since my warranty is still on.

Thanks for your time & advice btw..
 
The mtmfs process is putting high demands on your system. That's the Mobile Time Machine file system daemon. Try disabling Time Machine local snapshots by entering the following in Terminal:
sudo tmutil disablelocal​

Oh thanks. Finally someone saw the obvious problem which could be seen in the very first screenshot.

@OP
Read GJJstudios post. The mtmfs process is causing your problems, not some "dust" in your machine.


@negativzero
The screenshots are fine for me. Maybe it's your browser.

Nope :(
Here's a new screencap
By the way streaming a video on Firefox is all i do at the time of screencap
Is this normal?

Ahh yess! The notorious Flash, which is an immense resource hog! That's to be expected. That's why I use Safari with ClickToFlash, to control which Flash content can play on websites.

Yes that's true but the problem exists with and without Flash & Firefox so i dont believe that would be a solution for me :confused:

Every screenshot you posted so far has your CPU under load. When you work hard, you sweat. When the CPU works hard, it gets hot.

Flash is bad, in particular on Macs. I stopped using it.
