Macbook Pro Heat

Hello, I recently purchased a Macbook Pro 15 Inch Retina display. I play games such as "Minecraft" on this Macbook Pro. After about 10 minutes of playing this game, My Macbook Pro's fans start to get loud and when I touch the bottom area or the keyboard area, it seems extremely hot. I don't care about the fans noise at all I am just wondering if this heat will affect my Macbook Pro. Like will it make it run slower or stuff like that. I play games for hours straight sometimes and if it gets hot like this I am worried something will happen. Yes, I understand that I have to play it on a flat hard surface so air ventilation will be better, I also understand that its normal to get warm, but I am worried if I play it for a while and it gets extremely hot something will happen negatively. Is this true and if it is how could I make it cooler when I play games.
SYSTEM SPECS ---- MacBook Pro Retina, 15-inch, Mid 2014. Processor - 2.2 GHz Intel Core i7
(Yes, I play it on a hard surface in a cool room)
Thanks,

Macbook Pros can be very good gaming machines, if you know how to use them effectively.
OP, the Macbook Pro is made out of aluminum which makes the entire case act like a heat sink to transfer heat away through material transfer. Obviously if you keep the laptop on a clothed bed, the case won't be able to transfer any heat into the surface it sits on and it will get very hot. You need something like the Targus HeatDefense Pad. It has crystals inside that when placed under your laptop, suck the heat out of the material and the crystals melt into gel once it cannot do more. I would buy 2 of these pads and switch them out appropriately while the other cools.
With this combination, you can get a very effective gaming laptop, because like other gaming laptops, it doesn't rely on pure air cooling but combines a giant heatsink with air cooling. I used to do this with my old Macbook Pro and I played games at near silent. I think newer modern laptops crank up the fan speed not based on ambient temperature but processor speed temp output nowadays. Thanks.

The fan in my Macbook Pro heats up

The fan in my Macbook Pro heats up quite fast.
I wanted to know how much it would cost to get it fixed as I don't have Apple care and my warranty has expired?

Buy an external microphone or a headset. Which type depends on what type Mac you have. The 13" model has a single combo jack, the 15" and 17" models have separate input and output jacks.

MacBook Pro heating up and fans at full speed

MacBook Pro heating up and gets extremely hot and fans constantly at full speed after upgrading to Yosemite 10.10 without even launching any applicaiton previously I was on Mavericks, I checked Activity monitor and a process called kexts is always running and have a large percentage of the CPU load I tried reinstalling Yosemite and the same problem happens.

Thank you That solved my issue I uninstalled Cisco anytime connect. My console had that kernel running in the background giving the error every second.

My macBook Pro heats up so hot and nearly burning my lap

my macBook Pro heats up so hot and nearly burning my lap. Anything wrong with it? Should I bring it to Apple store?

Here's a search of cooling pads for MacBooks. I use one that just elevates my MacBook Pro off my lap so air can circulate between my lap and it...... letting the Mac's fan work best. You have to keep the air from being blocked going in and out of it and clothing and blankets interrupt that.
MacBooks tend to heat up if you are taxing it with video games and steaming videos, etc.. Maybe yours is at the age where the battery may be on it's way out. When mine neared the end of it's life it heated up quite a bit raising the temps for the whole machine.
Here's the free Temperature monitor. Maybe it can point to something.

Does anyones Macbook Pro heat up?

I find that my Macbook Pro heats up and gets hot.
Is this normal?
Does anyone else find theirs does this?
It's not even a year old

It's normal depending on how hard you're working it.
Do a search for "Activity Monitor," launch the application, and monitor the CPU usage.

Macbook Pro heating up and draining battery after yosemite upgrade.

On Friday, I upgraded to Yosemite and I really like it. However my computer keeps heating up very quickly when doing simple tasks and the battery also drains. About 1% every 2 minutes when on Safari and having Pages open in the background. What can I do to slow down the battery drain. Before, on Mavericks I could get a whole day on Safari but now about half a day.
This is the report that I got from EtreCheck.

Macbook pro heating up

After I updated my macbook pro to lion os it is heating up and the fan stays on constantly. Does anyone have a solution or why the problem is occurring. Thanks.

That's the Citrix client. If you don't need it, uninstall it according to the developer's instructions, then reboot. If you do need it, contact the developer, or your company's IT department, for support.

Macbook Pro heating up after Lion upgrade (time machine)

Hello,
After the upgrade from OS X Snow Leopard to OS X Lion I noticed my mid 2009 macbook pro 13" started heating up quickly. After some time trying to figure out what could be the cause I found TIME MACHINE to be the point. The automatic backups takes much longer than on SL, sometimes never finishes. Then I have had to turn time machine off. But this isn't the way I want to go on my Mac.
Any suggestion about this? My backup device is an USB HDD connected to an Airport Extreme.

Removing all old Snow Leopard backups and starting new backups from the scratch (with Lion) seemed to fix the problem.

MacBook Pro Heat Issue

I just recently received my MacBook Pro this past Wednesday and I've been addicted since. This is the first Mac I've ever owned and felt it was time to move onto something better and more stable than M$. I do use Linux but it doesn't have near the support like Mac does except maybe Suse (only because of Novell).
My problem is my MacBook Pro gets very hot. I've read the entire book that came with my machine and I noticed that it said that the operating temps are between 50-95F (10-35C). Am I reading/understanding this wrong? I've performed average use of my machine and have used a Class 2 Laser thermometer (made by Stanley) to take the temp and i've reached up to 115 degrees F just above my function keys.
If i remember correctly from left to right it goes Northbridge, GPU, and then CPU. The 115 mark was at my CPU on the far right side. I also never hear the fan on this machine come on. This is the quietest lappie I've ever heard after extended use. You hear the fans spin up all the time in the Dells, Gateways, Compaqs, etc.
One of my coworkers turned me to the overheating issue with these machines and it made me quite nervous. I understand that they had somebody who had cerebral palsy apply the thermal grease. What i gather and understand is that is now become an insulator instead of an adhesive. Is there a Real way to remedy this situation?
I've read stories of people having this issue and stating they took the machine apart themselves, cleaned up the goop, reapplied AS5 and their temps dropped (from reports) 15-25F and even only 2 degrees F. I know that silicon can take a beating in the heat but i'm kind of worried about the other components in my machine.
Is this firmware update really going to make a difference or is this some form of coverup? I'm being cynical now but i'm worried that such a great product is going to be a very large paperweight. I ran tests on my old Gateway 600 series laptop (top of the line when i got it) and it hangs and about 98-99F at its high points. The fan also kicks on and is loud as **** but seems to cool it enough to be reasonable. Although, this machine does make me quite warm when sitting on my lap.
Does anyone have ANY ideas as to what can be done? Or what have you done to try and remedy the issue? Am I doomed like the rest of you that have this lappie? I haven't seen anything from apple about this issue other than some firmware update.
Thanks for the help and ideas in advance!

Master P, you did misunderstand Apple's specifications for the range of operating temperatures. Those specifications apply to the ambient environment in which you operate the computer. In other words, Apple recommends against using your computer if your room temperature is at 95 F or above, or below 50 F -- temperatures that would be uncomfortable both for you and the computer. Of course some people such as photojournalists do productively use their MBPs in extreme environments such as the Sahara Desert or the upper slopes of Mount Everest, but I'm sure they understand they are reducing the life expectancy of some of the components, such as the hard drive in the computer.
A temperature of 115 F or higher on the metal strip behind the function keys is perfectly OK. You don't need to touch that strip to use the computer. My criterion is whether the parts that I need to touch remain comfortable -- the keyboard, trackpad and wrist rest areas. They do on my computer, although the left wrist area can reach body temperature after extended use.
In my opinion the recommendations to remove and reapply thermal grease fall into the Urban Myth category and do not make technical sense. And performing that "fix" will likely void the warranty and an AppleCare policy, should you subsequently have a logic board or CPU failure. The "fix" will be immediately visible to Apple service folk should the computer have to be sent in for repair.
No, you are not doomed. My CPU temperatures after hours of operation generally run in the 40 to mid-50 C range, depending on what I'm doing. At the moment CoreDuo Temp is reporting 48 C. Continuous 100% load of both processors for extended periods results in CPU temperatures in the 60s-70s C, which is well below the maximum continuous operating temperatures specified by Intel.
The SMART disk temperature of my 7,200 rpm hard drive has always been reported by Hardware Monitor to stay well below the operating temperature maximum of 55 C recommended by Seagate.
So I expect to get years of useful service from the MBP.
Both because I like the tilt for typing and because it provides an additional heat sink to cool the computer in heavy use, I use an aluminum tilt stand whether the MPB is on my desk or in my lap. I use a KoolSink because it's very portable, but there are many laptop stands that work well.

Macbook pro heating issue

My new macbook pro bought in 2013 13.3'' 8gb ram 2.9 ghz seems to heat up a lot in the bottom of the notebook when am just downloading too much from the internet... Is this normal or is there some problem with the laptop

It probably is normal. If you want to check, download from the Internet, 'istat menus':
http://bjango.com/mac/istatmenus/
Open Activity Monitor and set it to ALL PROCESSES and %CPU to display values from high to low.
When the MBP gets 'hot', take screen shots of both and post for evaluation.
Ciao.

MacBook Pro heats up crazy while playing games

Hello all;
I know the heating up issue has been raised several times all over the internet. But none of the discussions has satisfied my the concerns I have with my system. So I am going to put my case a new, although I believe the answers are going to be the same as on other similar discussions.
I recently bought MacBook Pro (15 inch, 2.2 GHz, late 2011, OS X Lion) and also I am new to Mac. The system usually runs perfectly. I just have two issues:
i. Occassionally it freezes up when more then one apps are running. I have noticed this is usually when Firefox is running in the background. Also happened with Safari a couple of times.
But my main concern and query is the point no. ii (below)
ii. During the normal usuage the fans don't make a noise (even with multiple apps that are not burden on the RAM). The systems heat up is as normal as that of a PC while running on its normal situation. However, when I play games (like BioShock, Sims etc) Mac just heats up immensly and fans kick in. I have never seen/felt a computer get this hot before.
How do I fix this?

I know Firefox has a slight issue with the way it handles RAM, so does Chrome, it has to do with the add-ons and how the unused RAM gets returned for using for another program.
Safari might have a memory leak, it also could be now with 64 bit everyone is rushing out to grab as much RAM as they can, trying to turn their browsers into platforms.
After all, if you think about it, browsers are becoming so powerful that they can actually run software within them, so perhaps Apple is messing with Chrome and Firefox's memory so they can't grow too large and takeover? Just my thoughts.
ii. During the normal usuage the fans don't make a noise (even with multiple apps that are not burden on the RAM).

3D games (or anything 3D) works the graphics and if you have a dedicated video card (the 15" does, the 13" does not) then that heats up too, thus the fans go up.
CPU intensive programs will heat up the processors and the fans go up.
Mac's come with Intel processors and they come with integrated graphics which performs some graphics capability, but can't handle 3D very well at all.
So the way the Mac works with a dedicated video card is it uses the integrated graphics on the CPU for as much as it can then hands off to the dedicated video card.
What you can do is open your System Preferences > Energy Saver and turn off graphics switching, that will use your dedicated video card only, located separately from the CPU and thus concentrate less heat on one spot on the logicboard, you should have a cooler machine.
However 3D gaming will of course always heat the machine up, perhaps a lot less as your not using the integrated graphics which is lousy anyway.
Another issue is 3D games are usually produced for a specific OS version and they milk it, perhaps don't see the value of making a update that works with a new OS X version, rather concentrating efforts on the next version of the game.
So it's ideal to only run games that are designed for the OS X version your using. Which Apple changes the OS version often, now once a year with 10.8 coming out this summer, why there isn't a whole lot of 3D games for the Mac, not to mention you can't find or upgrade video card like on a Windows tower.
So with 3D games, OS stability (Windows remains the same for 10 years) AND the option to replace the video card is paramount.

MacBook Pro Heat in Apple Manual

Appendix B Safety, Use, and Care Information 107
Using Your MacBook Pro
When you’re using your MacBook Pro or charging the battery, it is normal for the bottom of the case to get warm. For prolonged use, place your MacBook Pro on a flat, stable surface.
Do not leave the bottom of your MacBook Pro in contact with your lap or any surface of your body for extended periods. Prolonged contact with your body could cause discomfort and potentially a burn.
The bottom of the MacBook Pro case functions as a cooling surface that transfers heat from inside the computer to the cooler air outside. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures.
In addition, warm air is vented from the slots in the back of the case.
Warning: Do not place your MacBook Pro on a pillow or other soft material when it is on, as the material can block the airflow vents, in particular the rear vents, and cause the computer to overheat. Never place anything over your keyboard when operating in closed-lid mode. This can cause your computer to cycle on and off which might create excessive heat and drain your battery. Never turn on your computer unless all of its internal and external parts are in place. Operating the computer when it is open or missing parts can be dangerous and can damage your computer.

Just an observation - I believe people when they say
that some MacBook Pro's run VERY hot. If I had one
that ran as hot as some are saying, I would not see
that reading the manual made much difference to me.
Also it is appearing there may be some reasons why
some are running hotter than others (heat sink
compound issue). Even if the manual clearly states
this it "appears" there is still a heat related
issue. I have a hard time understanding why a few
people can't see the reaasoning behind that. Then
there are some that say that all Macbooks whine even
after so many people have said they have one that
doesn't and have had several people test these, young
and old. My conclusions after reading this posts are
there are some that whine, some that have heat
problems and many that are having neither of these
problems. Why is that SO hard to believe ? And thanks
to the good explanation about our expectations in the
previous post. Very well said.
I believe it's the same with the new airport extreme card. Mine disconnects much more frequently than the other person in my office who has the same configuration macbook purchased at the same time. (And it's not the airport express we're running off of because mine disconnects at home too)

Firewire iSight & MacBook Pro Heat

I am able to use my firewire iSight with my MacBook Pro, but unlike the internal iSight, there is an awful lot of heat being generated. In a matter of about 30 seconds, the temp of CPU A Temp Diode climbs above 140º F. If I continue with the cam, the temp will rise above 160º.
Does anyone have any experience with this? Is the firewire iSight fully supported on Intel Macs?

Hello enduserguy
My laptops are not iNtel Macs, but, until you hear from some of the MBP users here,
(1) if you are using your Mac within the operating limits of MacBook Pro's technical specifications
(http://www.apple.com/macbookpro/specs.html)
Operating temperature: 50° to 95° F (10° to 35° C)
Relative humidity: 0% to 90% noncondensing
Maximum operating altitude: 10,000 feet
AND
(2) if you are not blocking your MBP's air vents,
your Mac will take care of itself.
There are lots of MacBook Pro Discussions threads about CPU temperature, but I refer you to a couple of highly regarded MBP users, Ricktoronto and Kappy, in http://discussions.apple.com/message.jspa?messageID=5210021
Read and follow the instructions in your manual and you should be fine unless your Mac needs repair by an Apple Authorized Service Provider. If you are actually worried about your Mac rather than merely curious, see your Service Provider for a professional check to be certain there is no problem.
If you decide to continue to monitor the numbers, iNtel's spec is 100°C
(http://processorfinder.intel.com/details.aspx?sSpec=SLA44)
The 160°F you mention is only 71.1...°C, so things still would seem fine to me.

Why does macbook pro heats up around the left side and CD spines wildly?

I am experience heat from under the body of the computer on the left side. And also when the CD is in the drive, it runs really fast and loud. Does anyone have any reasoning for these concerns of mine? Mainly I am concerned about the over heating of the computer near the left side.

Hi,
I set my MBP up by transferring everything from my iMac (also an Intel Core Duo model). One piece of shareware, Net Monitor, didn't like something (partly, perhaps, the fact that it detected a single license key shared by two computers on the same network) and though it told me about this (duplicate license key) and allowed me to go on using it in demo mode, it ended up soaking up CPU. I didn't notice this right away, but I had the MacBook on my lap (and was wearing shorts) and after a while, the bottom got very hot. Then I noticed the CPU was pegged. Using the Apple "Activity Monitor" I was able to see which process was the culprit and kill it.
Anyway, a single run-away process like this can use up a lot of CPU and hence a lot of battery power. Use the Activity Monitor to check for such a process. There's a nice feature in Activity monitor, a floating CPU utilization bar. I keep it showing down in the lower right corner so I can notice if something like this happens again.

2012 15 Inch Baseline Macbook Pro Heat Concerns

I just bought my first mac computer ever less than a week ago. The baseline 15' Macbook Pro. I love it and don't want to hurt it. Thus when I'm playing games like Diablo III, SC2, or Minecraft I get concerned with the level of heat radiating off of my precious new toy. Is this something that should be concerning to me? I don't really see any vents on the body of the computer itself. Is there something that I should know as far as how to treat my macbook to make sure I don't burn it out? Is it the way I'm holding it? Should I get one of those fans that go underneath the laptop? Should I just ignore it? It seems to get much hotter than it should. Any advice is appreciated.

Do you own a Retina which has a better designed airflow system because of the side vents.
No you don't. You have a baseline Macbook which airflow system is towards the backend.
It think it's rude to go around slingning answers at people without understanding the questions.
Slinging answers? Can you point out what I didn't understand in your questons?
How many people responded to your questions again? 2. You know why? Rude....That's why.
Look at every response you got from me. Not one rude, name calling word was forwarded towards you. Now look at your responses.
