Can Someone Speculate Why SOME MBPs Are Cooler After Updates?

Great news:

I found the screw!

So, totally I spent 6 hours for this work - 3 hours to assemble and disassemble my MBP and 3 hours to find a screw on the carpeted floor in the library.

I have a screw that I messed up on the DVD Drive bracket or something, but I don't worry about it because I don't need to unscrew it unless the DVD drive is broken.

Question:

I neglected to re-read Jean-Cyril's post or the Arctic Silver 5 instruction on their website and followed the instruction of the guy who sold the AS5 to me. He told me to make a "X" line on the each surface of the chips. This is bigger than "the amount of the size of rice" in the AS5 website, although smaller than the original paste. If the mode of work is more important than the quality of the thermal compound, do I need to redo this work?

I never ran the whine fix as I had no whine. As a matter of fact I don't run any widgets.

No, you should be fine.

Thanks a lot.

If you get your logic board replaced shouldn't the thermal compound be put on better as I imagine the repair is done by an apple technician. I would hope that apple technicians are not putting on thermal compound like the way I see them in the pictures.

I also returned mine to Apple techs, had the same response. Still very hot.

From my interpretation, it sounded like Apple's warranty was basically "If you open it up yourself, and break something, you're on your own. But if you don't break anything, we won't hate you for opening the case yourself.

In a perfect world. People make mistakes when opening a computer, and I believe that Apple asks if yours was "tampered with" before servicing it. Apple will often assume that you caused the problem rather than wasting their techs' time.

Couple of things: (1) If the back of the MBP is
elevated there seems to be better air flow, thereby
enhancing the cooling effect of the fans, whereas
when the MBP is on a desk, some heat may reflect
back--essentially same issue with the Powerbook G4.

I've always used something like a Podium Pad or iLap, even with my PowerBooks, and heast isn't a big issue. Same with my MBP.

They may not admit it's an issue but I sent my back for the CPU whine and they replaced the cpu and also (CBL, Temp SNSR, Heatpipe,M1) and part 593-0290 (CBL, TEMP SNSR, RT FINSTACK,M1. This has nothing to do with the whine and it is a lot cooler. Barely warm when running battery and on my lap. It still gets a little hot when plugged in but nothing like it used to. The whine is still there by the way.

where did you purchase your arctic silver products? online or at a store?

So unless yours is really to hot to touch, it's
probably running normally; that is, very hot.

What is 'very hot'? I've heard almost every description of heat here from 'comfortably warm' to 'hot enough to fry an egg'. Sensory heat is subjective - one reason you're likely not hospitalized if your forehead 'feels warm' but if your temperature is measured with a thermometer and your temp is 105º, you should be prepared for at least an overnight stay and some tests.

I have been practically screaming for those who claim that they can set up a Waffle House griddle on their MBPs to either get the eggs cracking or use an IR thermometer to actually measure the temperature! Some are cheap, some are $150 or more... even the cheap ones are accurate to within ±3º or so and if you don't want to buy one then rent one, or ask a friend to borrow one (don't think you'd have friends that would have one? You'd be surprised... pest control pros use them to find hives of bees infesting housing).

So, please, I beg you - before you complain, ad nauseam, about the ability of your MBP to fry an egg, take its temperature! Then the abundance of triage nurses here will be more informed when passing you off (or not) to the ER doc...

Jean-Cyril,
Bravo. Great research. I had similar over-heating issues with an HP nw8240, a workstation class notebook. I've got several photos of the ridiculous amount of thermal paste "plopped" onto the 1.86 Pentium M. After cleaning up the mess and reapplying AS5 the high-pitched whine and blistering hot upper deck disappeared. The minute I heard the whine and hiss of my MacBook Pro I drew the same conclusion. Thanks for confirming.

Mine's NOT cooler after both software update (to 10.4.6) and Firmware update. Throw in a keboard update to boot...heh. I asked myself the other day, "Is this what i want to experience all day every day--discomfort to have hands on or even over the keyboard?" I don't think so. My MBP sits with airflow space under it and behind it and on *all sides,* yet it is very hot. I'm tiring of it.

I believe my 2nd fan is not kicking in. How canIi test that, if at all? I haven't heard it in a long time. I use my MBP all day, but it sleeps when i'm not using it.

I'd love to hear what Apple customer service is saying to any of you who have called in about this. Any other advice is welcome. (I've not run a widget hack or otherwise taken any measures other than Apple's suggeston to use the Better Energy performance setting.)

See the genius thread I started, but I took it in to an Apple store and while he claimed it was normal and that ALL MacBook pros were that hot, I showed him the IR thermometer temperature of 140 F and he agreed to send it in for repairs. I somehow doubt they'll do anything about it 😟

With the greatest of respect a portable laptop needs to be used on the lap yes?

If its too hot to have on your lap then its not fit for purpose, you should send them back to apple and get your money back.

Hacking around with 2 grand laptops to fix this issue is not a solution, they are not fit for purpose. Return them.
