New 2011 15" MBP - running WAYY hot?!

Pretty sure every tear-down I have seen looks as though a 3yr old applied the thermal paste to the chips / heatsinks. I wouldn't be surprised if that's the cause.

In fact, someone showed in an earlier thread an exact example of what I meant.


2 solutions, and I know what I'd choose.

1.Return it.
2.Open it up and re-apply the thermal grease.

I'd go with option 1.

I have another thread open for the 13". For sure there is too much thermal paste, but I also believe Apple still needs to fine tune the algorithm / parameters by which the fan engages.

It is obvious from my testing on the 13" that the fan was engaging too soon in many instances, and too late in most, finally resulting in a jet take off sound.

I have since installed SMC and written a script to allow me to toggle cap the fan settings. Been running @ 1,800 - 2,000 RPM all day at an average temp of 38/39C.

I expect Apple will fine tune the fan issues in a future fix / update.

Well, I got the old machine returned, and the new machine setup. It's a completely different animal! Where the last one would idle upwards of 70C, the new is between 38 and 42C. Just played L4D2 for a good 30 min, and it never broke 85. Installed the SSD, and I'm lovin' it!

For what it's worth, I've been using Hardware Monitor as well as smcfancontrol for temp monitoring in OS X and hardware monitor + lubbos fan control in win7.

Thanks for suggesting I return it. I'm really glad I did. :cool:

Glad to hear everything worked out! :)
 
My new MacBook Pro is also running very hot for some reason. My 2010 i7 ran at about 40ºC at idle; this one is running at 80ºC at idle; when doing anything it jumps to 95ºC-100ºC which is quite terrifying to say the least.

From the iFixit teardown it appears the globs thermal paste may be the culprit; I will replace the thermal paste to see if that fixes my issue.

But if it doesn't? Then you'll want to return it and you're at risk for not getting an exchange. I'd swap it first. It should be at ~40 idle.
 
Welcome to the world of "Hot Macs"

It's Normal says Steve, there's a price to be paid for a thin supermodel laptop.

Apple doesn't care about proper cooling, they just want you to keep buying new ones.

Fried eggs anyone :)

My plan was to replace the thermal paste anyways.

Plus, err, the stock HDD, RAM, and optical drive are no longer in my possession. :p

obviously it will get hot, its a quad core.

set the fan to 6000RPM and you're fine.

Quad-core means nothing; it has the same thermal output as the old dual cores, so it should be fine.

And if you read some of the other posts, people have reported a replacement machine resolved the issues.
 
My new 13" with the i7 seems high also, I just started Handbrake, and the fan has been on high since. Temp shows 89C for CPU A Diode.

Nice, replace away then. Ceramique? I'll probably do it soon too once I've decided for sure I'm keeping the 17.

Can it even get that hot before crashing? You better hope that didn't damage it!

That's what hardware monitor was reporting just before it crashed. I don't really care if it damaged it, because I returned that machine:p New one is great.

FWIW, before It crashed, you could tell it was throttling itself pretty badly. FPS went down to 10-15, and it was stuttering way bad.

I'm running firefox, itunes, steam, utorrent, and parallels with excel and i'm only at 47. Such a big difference between units.
 
FaceTime is the culprit for me. After shutting it down, my CPU temp dropped from 77 to 52 in 60 seconds.
 
Crossing my fingers...

I hope my new 15" doesn't have the same heat problem. If so, it's back to the Apple Store with it...

Heat issue

Heat

The 15-inch MacBook Pro held up well during our heat test, where we play a Hulu video at full screen for 15 minutes; the space between the G and H keys remained a balmy 90 degrees Fahrenheit, and the touchpad measured just 83 degrees. However, the back rear bottom of the notebook reached an uncomfortable 106 degrees. We consider anything above 100 degrees to be uncomfortable.

from laptop mag review
 
My new 15" 2.2 with Eudora (yep, the old version) and Safari with a few windows open running has the CPU at 49C and the CPU heatsink at 41C (per iStat Pro). The CPU is mostly idle and the fans are running at 2000RPM.

Went into WoW with most of the video settings set to "high" and several at "ultra" and flew around Teldrassil for five or 10 minutes. The CPU got up to 87C.

Overall, this machine seems to run cooler than my old C2D unibody. At least my lap doesn't get as hot.

I'm going install Bootcamp tomorrow and will be trying out some Windows games. My old C2D machine would overheat and shutdown after about an hour of Bioshock2 if I didn't use a cooling mat. We'll see how this machine does.
