15" MacBook Pro (SB) Thermal application/guide

[kappaknight]

Under full loads, my CPU and heatsink temperatures are still around 20+ degrees apart.

I think full load temperatures have dropped a couple of degrees. Once the task is done, the computer does cool down way faster.

Up until I added a SSD, I was still idling close to 50 degrees. With a SSD inside, my idle is in the lower 40's.

I really don't think the quad-cores run any hotter than the C2D's. When I was comparing mine after the mod, the new laptop was running cooler than the C2D that I got from 2008. I would assume it's all been the same - we're just now bringing this topic up more so than before.

does CPU temp report the wrong temperatures? i'm reading 9between 92-96C :

That's not abnormal for a max.

That's not abnormal for a max.

i'm not shure it was max, i mean i was playing assasins creed brotherhood , but that's it, will the thermal paste help lower the temps? even if by afew c's?

Thank you,

Should I bother?

41C idle, fans @2k
88C full load, fans @5k

This seems completly normal

Just re-apply thermal paste my brand new 13" 2011 MBP with Artic Cooling MX-4. Noticeable improvement in thermal output. My previous idle temperature was 58ºC, now is 45ºC.

great thread, it should be a sticky

Looks pretty good as is, so you probably don't need to

Did you used a specific disassembly guide? Can you link to it? I'll be doing this on a 13" next week and I'd really welcome some guidance as there are no manuals for 2011 13".

Thanks!

Using iStat Menus, i see the following temps:

CPU1, CPU2, CPU A

and

Heatsink B, Heatsink C

Where exactly are these sensors and which should i be most concerned with? It looks like iStat shows CPU A by default in the menu bar, but CPU1 and CPU2 both get hotter than CPU A.

I'm running a 2.3ghz quad i7, 2011

Here is the link. You just need to follow from step 1 to 21.
The 2011 and 2010 layout is quite similar. You have to use the right tools to remove the logic board.

Does anyone know? I am wondering this as well.

I'm just vaguely guessing here but CPU A (CPU/GPU Heatsink (Assembly)), CPU1/CPU2 (actual CPU/GPU), Heatsink B (Chipset Controller), Heatsink C (Thunderbolt Controller)

2011 MBP 15" 2.3GHz idle CPU temp - ATI6750, external monitor

here are few examples of the temps i'm getting:

all are with ATI active driving external display U2410

factory idle:

factory max:

Shin-Etsu G-751 idle:

Shin-Etsu G-751 max:

that's a BIG disappointment. what temps are you getting with setup similar to mine ? the paste didn't do ****

 

[daneoni]

Thats because those temps are largely normal. I run a similar setup and whilst i've only hit 92C once, the average temps tend to stabilize around 78-86C as fans kick in and time goes on during full load.

I assume you're running clamshell mode? if so you might want to keep the laptop open because it makes a significant difference.

Remember, Quad-Core processors with iGPs drawing 45W of power in less than 1 inch thick enclosure and thats not even taking into account the GPU. There's also the ambient (room) temp to worry about...

the laptop is open - i use both screens. i was expecting 1-2C drop on average, but it's virtually the same...

wonder if i put too thick paste layer... or i was just too optimistic

 

[daneoni]

Both equally plausible.

Here's mine. Laptop closed and connected to an ACD. Safari (active use), Mail, iTunes, Adium and some other utilities running. As soon as i play flash HD videos or HD video podcasts in iTunes though, temps jump to 63-70C.

NB: Windows are open so the room is fairly cool. Also i have made no modifications to my machine.

huge difference. did you apply different paste - brand ? how thin ?
do you have the same 2.3GHz ? what happens when you open the lid and use both displays ?

Thanks, I was planning to use that one combined with the 2011 15" teardown, but I guess the 2010 will be enough.

Thanks again.

Nope i haven't touched my machine...all factory. I have the 2.2GHz model. Temps and fan speed go down when the display is opened...regardless of what i'm doing. However, they go up if closed even if i'm just playing HD videos.

Those temps are consistent with the 2.3 15" MBP I saw yesterday in the Apple Store driving a 27" Cinema Display, so I'd say they're probably normal.

 

[Macsavvytech]

great thread, it should be a sticky

I disagree some may not understand the risks.
I will never do this to my MBP, if something goes wrong...

Even before paste on load my max CPU was like 88c and gpu at 70c. Brand of paste?
