I recently purchased the mid 2014 macbook pro (15 inch w/ 750m) and have noticed it overheating. The bottom of the laptop gets uncomfortably hot and the top of the keyboard to the screen is too hot to touch. Looking around the forums I saw that a firmware update may resolve some of these issues, but i don't see my macbook on the list of devices on the apple support page.

My system info:
Model Name: MacBook Pro
Model Identifier: MacBookPro11,3
Processor Name: Intel Core i7
Processor Speed: 2.5 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 16 GB
Boot ROM Version: MBP112.0138.B07
SMC Version (system): 2.19f7
Serial Number (system): ------------------
Hardware UUID: ----------------------------


I've noticed newer versions of the SMC, if higher numbers = newer.

I also tried SMC fan controller, but it believes that my minimum fan speed is 4500, which is quite loud if the machine isn't running hot. If there is any way to fix this that would be helpful to.

Mine is identical to yours! the only difference being the serial number and UUID ...no overheating issues to report here.

I don't see any firmware updates for the Mid 2014 models on the support/downloads page, where'd you see the update?

I think I'd be looking for a hardware issue if I were you.

What is running when it gets hot? Need to look in Activity Monitor, CPU tab.

I use Temperature Gauge Pro for any non-standard fan control...

Let me get this straight. You expect a machine than is less than an inch thick, has a quad core processor and discrete graphics card jammed in there, and uses the chassis as a giant heatsink to run cool?

You should search the forum, there are THOUSANDS of thread just like yours with people thinking their computer is overheating. Truth of the matter is, your computer isn't overheating. If it hasn't shut down in your face out of the blue, then it hasn't ever overheated. It is running within design spec.

Just use the thing, it's a tool, that's what it's made for.

This should be just pasted into everyone of these threads.

SMC Version (system): 2.19f7

I've noticed newer versions of the SMC, if higher numbers = newer.
It was on the 2013 mbp, SMC 2.6f18, or something like that
Well, strictly speaking, the '19' in '2.19' is a higher number than the '6' in '2.6'. Perhaps if you took '19f7' and '6f18' as whole numbers expressed in hexadecimal, then yeah, 6f18 would be higher. But every SMC firmware version I have ever seen on any recent Mac always has the format "X.YfZ". So I take the 'f' as a separator of some kind, like the decimal point, and not as part of the number.

What are you running that your temps and fans are ramping to their max? I think that needs to be determined before anything else. Is it Flash? Gaming? VMs?

I just got a maxed out mid-14 (with the 2.8ghz). Idle or light load the temps are 50-40C and it goes up from there. Under heavy load (Dropbox has been doing a lot of indexing and backing up) it'll spike to 99C and then drop to the upper 80's.

Pretty sure that's normal behavior. But I'm open to confirmation! :)

It runs between 101-103 C while browsing the internet and will shut down if I try playing League of legends. The fans dont ramp up though, hence why I installed SMC fan control.

If it runs at over 100 degrees CELSIUS while browsing the internet, you have a serious problem. You should have stated that immediately in your first post.

For me, my temperatures while browsing the internet are around 39-44 degrees (late 2013 high-end 15-inch). Right now it's actually at 37. The highest I've seen it go is 97, though if it starts exceeding 90 degrees I usually start using smcFanControl.

I've found that when gaming, it is very useful to have the fans at a constant 3000 RPM, since otherwise the fans fluctuate between idle until the system reaches 90-95 and then goes to 4000 or 5000 RPM, which is quite loud.
