New 2011 MacBook Pro Heating Issue?

Do you have a any increase in fan speed and noise when you watch flash videos or even open 4+ applications on your macbook. Have the same model and the fan hikes up in speed considerably doing those same things whereas on the 2010 model it was always quiet and i mean scarily quiet!

with such a powerful cpu and gpu directly on top of each other you can see why they changed the sensitivity settings of the fans.

I wish apple would create some kind of 'silent mode' for when the user prefers quiet to speed.

hmm, I think people need to start including their ambient temps for us to get an idea of where peoples machines are really at, a 15-20 degree difference is a huge amount to the cpu temps.

for example my stats are:

ambient = 22 c
cpu = 20%/62 c
fans = 2000 rpm

seems the integrate graphics is not causing much of the mbp heat issues after all:

Everything points to them being the coolest running laptops to date...

Well in theory it may be but in practise the 13" run hotter than the 2010 models as I used one for a week and noticed considerable differences in idle, working and heavy usage.

I've just returned my 2011 model and got back a 2010 because the new processors and integrated graphics if they are the cause run the macboo 10-20 C warmer than the 2010 model. As soon as you increase the workload, the heat becomes an issue with readings of around 80-90C which is riddicoulous compared to at best 60C.

So in my experience in both models, yes the 2011 is speedier doing some tasks and I have noticed that speed in Parallels but other than that I prefer the older, cooler model yet still as fast if not a tincy bit slower.

Ps. I went to the apple store today and installed iStat on 3 different 13" machines just before I returned my 2011 model as reassurance I was doing the right thing. Confirmed, they all run exceptionally hotter.

It doesnt add up that they run hotter considering sandy bridge is 32nm and roughly 20% more energy efficient than the previous generation 13" which had about the same clock speeds.

they should be running noticeably cooler on paper!

Im looking for a 15" myself but they are not immune to the problem it seems.

It all comes down to thermal paste.

Mine is.

Buy one. If it runs too hot and noisy, you'll know within hours. Bring it back and exchange it.

Time for me to eat claim chowder: my 2011 13" MBP i7 is running relatively cool and quiet.

Since I was starting to read conflicting reports - and I had a fair bit of time left within Apple's return policy - I decided to give the new 13" a fair shake and put it under truly identical conditions to my 2010 MBP: stick in the same SSD drive, place it in the same desk location as my 2010 version, and connect it to my 27" LED Cinema Display (which requires that the MBP drive a 2560 x 1440 display, for those who aren't familiar with the specs).

Then, I let the computer sit overnight so Spotlight could finish indexing, and I open/closed a host of apps so that caches could rebuild. Then I set the computer to my standard use: four open Spaces, and run Safari, iTunes, Scrivener, Adium, Pandora, Mail, and OmniFocus concurrently. I then set to work as I usually do, including breaks to view videos on YouTube, Vimeo, and TED.

In my general use, I'm seeing 45°C and fan RPMs are staying just under 2000. In short... pretty much the exact same as my old 2010 MBP. It was warming up to around 76° when I ran 1080p YouTube videos in full screen (at 2560x1440), but the fan didn't ramp up - though I imagine it would have if I'd been looking at something longer than an 8-minute clip. But, even my 2010 MBP did at that point.

Long story made short: If you're seeing heat/fan spikes, keep on using your system for a bit to let Spotlight finish indexing (the mdworker process is notoriously CPU intensive), let your system caches build, and things will probably calm down after a while. Also, do what other users have done and make sure you don't have some errant runaway process taking over your CPU.

Ultimately, I'm glad I had the patience to keep working with the 13" MBP i7... because now it's fine. 🙂

This is the exact issue I am having. As I was downloading and install various things after first getting it, the MBP was reaching absurdly high temperatures (with the CPU specifically) of 185 to 190 degrees farenheit, and sitting there until I killed all processes, put it to sleep, and woke it up again.

I have a new i7 and have not experienced any heating issues even when using handbrake to convert a 2.5 gb video file. The fans do spin up to their maximun speed, but this is expected considering that all four logical cores are at 100%. During everyday web surfing, DVD, e-mail, etc. I do not hear the fans and the bottom of the case remains cool. This weekend I will try some other compuationally intensive tasks and see if the results are similar.

So, I got it, i partitioned it, installed office 2011, norton internet security 2011, copied of 20gbs of necessary books-pdf-docs-photos, played a couple videos and working with e-learning over the internet.....the last 5-6 hours...... Temp:44C, fans:1999rpm. Tried lunching ALL TOGETHER so to see Temp reaching 78C and fans:2300 for a couple of minutes...... noise only from the dvd while installing...... i am pretty happy....it is lighter than my 15"MBP when working on bed now..... NO ISSUES HERE..... with the current software and use at least. I only have to install my hp e-all-in-one printer and see... in the future i'll update you after some video editing from my high-def camera...
I don't think I will try any games though..... are £1300 laptops for games??? Seriously???? that would be a waste of money..... IMO... but whatever makes everybody happy... I will keep everybody updated... 🙂 😉

Yeah, no harm in buying one. If you experience a problem take it back, exchange it. Always have time to test the performance. I just seemed to have a bad model or ho that just ran like crazy. But happy with it now 🙂

I just got my 15 Macbook pro with 8gb of ram:

Model Name: MacBook Pro
Model Identifier: MacBookPro8,2
Processor Name: Intel Core i7
Processor Speed: 2.2 GHz

And the fans on this thing is ridiculous, not when using regular apps like Safari or Textedit etc, but when working within Adobe CS5 After Effects, for example, when rendering a 6s long test sequence the multiprocessing starts fine and all, but after a few seconds the fans go MAD! and a few seconds later the whole computer hangs... closing the lid, keyboard commands.. does nothing... so all to do is a hard restart pressing the power button.

I will try some renders in Final Cut Pro also, just to see if it isnt an adobe thing..

Only had one successful render so far, hopefully Apple will release an update, they always do.

we have gone from dual to quad core that doubles the potential heat which I guess is why the fans spin up so quick now. The heat sync looks very small considering they have to cool a quad cpu/gpu and discrete gpu.

I was imagining MBP going to a liquid cooled system and using the screens back as the radiator, that way no more burnt laps and silent computing again 🙂

Until then Id like to see more CPU options to choose between Power or silence with less power.

I think you're worrying too much. I'm ripping a DVD with Handbrake right now, all eight (logical) cores are maxed out and my CPU temp is stable at 86º, fans audible but not loud at about 5,800 rpm. For the ability to rip/encode at more than 3x faster than realtime, it all seems pretty good to me!
