Cleaned out my MBP - Still running hot

Today I just got tired of the laptop being uncomfortably hot. It generally runs between 70 degrees celsius and about 101 (according to TG Pro) which is not normal. I literally cannot run any intensive programs or my computer will overheat and shut down. Not only that, but now running Chrome instantly triggers the dGPU.

After waiting weeks for the correct screwdriver to open this pig up, it's still running just as hot with all the vents cleaned. What's going on here?:confused:
 
have you seen this old post?

It pertains to pretty much your issue but is outdated. It's worth reading and then move to the second link.

My 2012 15" MBP runs pretty warm. I use the app listed in the second link for fan speed regulation and also use the Book Arc (third link), which is expensive but allows placement so the hot air goes straight up, and augments the convection aspects of cooling.

I just never noticed it running this hot before. Definitely not "normal".
I'll check out those links, but I think it's actually a sign that the laptop is on its last leg.

That being said, I'm hoping it's tied to the problems described here

I reinstalled 10.8.5 after doing clean installs of Mavericks and Yosemite - yes I have to do without some new OS features but my 2012 rMBP is so much happier now.

Interesting...hoping 10.11 fixes some issues. But I mean I've been on Yosemite since the first beta (almost a year ago) and the heat issue is just getting worse so I don't think it is entirely because of the new OS. Also want to mention I never had this issue on Mavericks.

Quit using Chrome. It's a resource hog.
 
Chrome should not make your computer run hot.
Have you done a hardware check? Hold down D key after you press the power button to go into diagnostic mode and let it do its thing.

Chrome made my computer run hot, very hot, which caused the fans to blow way more than they had before. When I stopped using Chrome a couple of days ago the problem went away. Don't tell me Chrome won't make a computer run hot.

Chrome made my mbp run hot all the time, and hogged resources.
 
How did you clean it out? Sometimes you have to take the fans out to get all the dust. It also helps while you're in there to replace the thermal paste as well just to be sure you're running tip top.

You're right, it won't. I don't run it any more.

Actually it's an excellent browser for Macs.

It's our default at work across over 50 MBP, MBA, and some MacPros. Runs very fast, efficient and doesn't get wonky when one has loads of tabs open. Our IT guys love it.

Thanks Google!

Agree. I love Chrome, but can't use it anymore. I'm now back to using the awful Safari and none too happy about it. Chrome worked fine for a year and a half or so, then it didn't. I've since read of plenty of users having issue with it.

I literally laughed at your comment, you ****ing fanboy.

Chrome has been fine for over two years on my Mac until recently. Possibly related to Chrome updates.


"People who refuse to update software are bozos to me."

I really think you're a bozo for using "bozo"

I don't get why people insist on using other browsers on their Macs. I've never had anyone give me a convincing explanation.

Chrome runs one instance of flash per tab, that eats away at CPU cycles and RAM like nobody's business and yes, will make your computer run warmer than it would browsing with Safari. Add to the fact that its API's will trigger the dGPU (and always have, by the way) and you've got one shoddy browser.
 
Even if Chrome is making a system run "hot", the system should not overheat and shutdown if the laptop is otherwise working properly.

Everyone is focusing on the trees here, rather than the forest. Need to step back and take a look at the facts.

System is shutting down because it's getting too hot. This typically means that the system is not being cooled properly (not a huge surprise there considering it is a Mac.)

However, in the end, there is not enough data here to spot a definitive root cause for the issue.

Things that are missing, in no particular order (unless I missed it amongst all the "Chrome this", "Safari that" bits and pieces):

- Machine model and specs
- Was it purchased new or used?
- Any aftermarket mods or upgrades done to it (either by existing owner or previous if bought used?)
- Have any parts been replaced in it for any reason? If so, what was replaced.

Barring any of that info, here are some suggestions:

1. If it's an old system (like 3+ years) and it's used daily:
- the fans may need to be replaced.
- the thermal paste may need to be cleaned off and re-applied, and then allowed to cure properly before measuring new temps.

2. If it's a new system:
- thermal paste may need to be cleaned off and re-applied, and then allowed to cure properly before measuring new temps.
- (optional) have the fan(s) checked out. Possible that a defective one may be found, although more likely as the system ages.
 
Complete lack of data here, impossible to offer advice without data. Need MBP size and year, etc.

At the very least:

Open Activity Monitor when you hit high temp. What apps are pegging the cpu?

What's the ambient temp where you work?
