#302Earlier quoted context omitted.
When working as intern at an Apple store more than 10 years back the instructions from Apple for reassembly would always tell to put a huge amount of thermal grease on the CPU. So much that it would be squirted out from under the heatblock in large blobs. I always found it odd as I was used to add just as much as was needed without spilling over. Never read any research on it though so I'm curious what was the right…
If a bare-die CPU or GPU is not fully covered, the uncovered portions will rapidly become hot and the chip may die (especially if the thermal sensors are covered and cannot detect this). This is different from modern desktop processors where there is an IHS to help spread the heat around - there is a very real danger to insufficient paste application on a bare die. In contrast, since modern thermal pastes are non-con…
> there is a very real danger to insufficient paste application on a bare die
So, I've repaired and cleaned many, many laptops and computers over the years. For bare die components (CPU/chipset) I use something like "half a grain of rice per finger nail area". This is already plenty. I sometimes checked after mounting, and there was always some minor squeeze-out. (For desktop CPUs I also use just half a grain of rice. The higher mounting force results in about a ~3-4 cm dia circle; this doesn't extend all the way to the corners of the IHS, but it doesn't have to, since nothing is dissipating heat there.)
> there is no real downside to an enthusiastic application of paste except for making a mess
That's not my experience.
With laptops, the pressure applied by the cold plate is not that much and thermal pastes have high viscosity. (The cold plate is often not that stiff, too, so it tends to flex). Applying too much paste results in a too thick layer of paste, which results in higher temps, hotter laptops, fans spinning faster and thus more noise and annoyance.
Indeed often I found the issue with manufacturer-applied paste was that it was simply too much. I think the reason they do this is that it's harder to get wrong and it makes the product just more annoying, not break it. If they did it properly, there would be some chance of getting it wrong, resulting in a broken product. For the same reason they're using thermal pads wherever they can get away with it: They're practically impossible to misapply.

No

PS4 "Pro".

Why do you need 32 GB of ram?
Not the op, but I need 32 GB for:- - running virtual machines. - running MemSQL which requires a minimum of 8GB to be available. - running video editing software. There are probably other reasons, but those are the ones off the top of my head.
Similar to VMs, I run a lot of docker containers, mostly with JVMs in them.
I bought an Intel Hades Canyon with 32GB to run Linux on after the new MBPs didn't turn up at WWDC. Feeling somewhat relieved right now.

My favorite is the latest Air (years old now) which doesn’t even have a retina screen yet, a perk in my book. I could watch Netflix on my bare stomach with my Air. Latest Pro is quickly too hot to handle. Of course not the only issue but the computer never bounced back from that first impression. The dedicated gfx card doesn’t even seem to run games like Civ 5 better than my Air which I’m guessing is due to all the e…
> I could watch Netflix on my bare stomach with my Air Don’t try that with a first gen Air. It had a very significant problem with thermal related issues. Several times a week it’d get so hot I could make pancakes off it, the rest of the time it was in a throttled state. Was a very common problem among folks I worked with (albeit mine was a personal, theirs was a work machine) too.
The Air story is incredible. It went from compromising, underpowered, overheating, pricey, loathed and ridiculed, to everyone's favorite laptop, with excellent performance across the board at a stupefyingly low price point.

#307Here's a review from a dev who works at NASA: http://hrtapps.com/blogs/20180712/ Maybe the key point is he isn't running Adobe Premiere. The thermal issues in modern laptops certainly concern me, but they've been running hot for a long time now, and being thin doesn't actually change the surface area significantly.
Look at how fast the curves on the 2018 flatten out after 3 or 4 cores.

#308This is not a first for Apple.
I remember buying the 2006 Macbook with a CPU upgrade. A Core 2 Duo with 2GHz instead of 1.83. Due to heat, the CPU throttled under load and ended up with the same speed as the standard model.

#309It's summer now and as soon as I plug my MacBook Pro 2017 in to charge, it starts throttling itself due to the heat of the charging battery. Same thing happened to the 2012 I had before. These things just don't have adequate cooling.
In the summer I have to unplug one of my external monitors because my (maxed out) 2014 Macbook Pro gets too hot. I'm going to try using my linux desktop when it happens next, that at least has adequate cooling.
Same problem, I resorted to just have a fan blow on it to help with getting the heat away...

#310I bought the MacBook Pro 2017 13" without touch bar with an i7. I pretty happy with it, but, the only thing that bothers me is it gets hot. Hot as hell. Skype sharing the screen and JetBrains CLion and you get a beautiful roaster.
I have a 2016 Touchbar 13", doing anything Eclipse gets it hot. And I also have a 2016 15" that gets hot once you plug a monitor in. Not unusable or super hot, but just hot.
