[@danielsaturnino5715]

I would assume that cooling only works with the bottom cover on which diretcs the air being sucked in to pass on the heatsink.

[@justinspiredfallout]

This

[@pupil2720]

Yes I was wondering if it was reliant on the case cover. I do not think that their hardware engineers would be so stupid.

[@ro63rto]

That would be my understanding but still a crappy design.

[@Billy-rr7re]

@@ro63rto exactly, if having heat pipes usually does not provide a great deal of cooling because of limited space, depending only on a tiny amount of air rushing over that microscopic heat sink is even worse. that is assuming the cover helps that much when installed. not to mention the cpu is not the only component producing heat. so yeah, the engineers are probably stupid

[@pupil2720]

@@ro63rto crappy design yes, I can agree with that.

[@TheDefpom]

It probably relies on air being sucked past the heatsink when the cover is on, check where the inlet port is, I bet it is on the opposite end of the machine.

[@veasnanoeun235]

Exactly how the new MacBook Air cooling work but the flow of air isn’t narrow to just the heat sink; it’s a wide pathway!🤣

[@nickvogelius]

@@veasnanoeun235 If you look at the bag cover, they actually have tried to narrow the airflow so that it is limited to the area where your heatsink is located.

[@reuelethanrodrigues8780]

Yes

[@robp4616]

"If this CPU stays hot like this, it's going to shorten the life of the laptop." *Apple listening...* "Bahahahah, that's the point! Gotta keep them buying!"

[@piernov]

It's about airflow, cooling system won't work as intended if the back cover is removed. Also Apple always designed their cooling system so that it barely meets Intel requirements. Older model were also running around 100°C when putting the CPU under some load. Not saying it's good, but it works. According to Intel Tjmax for this CPU is 100°C so Apple most likely designed the laptop so that it runs just under that to avoid throttling. It allows them to make thinner, lighter and quieter machines. Also TDP is only 9W on this CPU.

[@ricardoelectronicsrepair]

agreed, but problem is it make heat spread across the board, cpu is durable but not its bga solder and other component like caps or mlcc or pwm ic that when fail can damage the cpu(bga cpu is expensive to repair). Apple just wants to save money.

[@piernov]

​@@ricardoelectronicsrepair that's not true in practice. Intel CPU are less and less reliable, the BGA soldering is not the problem in most cases. Indeed, other components case cause the CPU to fail and that's also becoming more and more common with VRM chips failing and sending an overvoltage to the CPU. A while ago it wasn't a problem. Since Haswell, they almost always die when this happens. Of course, since Haswell CPU became much more difficult to replace, especially U/Y series which are the ones to fail the most since they have both CPU and PCH on the same package. And of course since Broadwell there are no socketable mobile CPU anymore, they are all soldered. Intel is also the one that decides how much cooling is needed for a CPU, what are the safe working temperatures, and of course implement the protections over out-of-spec operations. None of that is Apple fault. If anyone is to blame, it's Intel. As for an MLCC failing, it won't damage the CPU, and MLCC failing on a CPU power rail almost never happen. And Apple saving money… that's clearly not the case. You can say that every other manufacturer tries to save money on their consumer machines. Not Apple. With the amount of engineering and manufacturing work they put into their machines, they're not trying to save money. They design their own chassis, they design their own boards, they even design some of their more complex ICs. It'd be *way* cheaper to outsource that, like most other manufacturers do. They don't manufacture most of their parts themselves, that's indeed outsourced, but with the complexity of the parts it must cost them a lot to manufacture. When you look at the quality of the 14 layers PCB that use a lot of 0201 SMDs with really tight design constraints, it's definitely much more expensive to manufacture than your cheap Quanta/Compal board. They also do a bunch of innovative design in the internals of their devices. It's a double-edged sword, it pushes the manufacturing side to refine their process, but it can also lead to all kind of unpredictable failures. Why do they design stuff like that… who knows, most likely because they want to do everything "in-house" without sharing it. It's well-known that Apple ecosystem is closed, so having control over everything makes sense, that's what they've been pushing more and more lately.

[@ricardoelectronicsrepair]

aggre too, except cpu cases. 12 years im working on notebook and dekstop repairshop only 3 times i find cpu damaged on its own 2 which is intel other majority cases is ec(ite/nuvoton) ic, short mlcc, and poscaps open or high esr. Open mlcc is rare but when it happen on critical circuit(clock and data traces) its hard to debug.

[@masteryoda394]

As everyone said in the comments section, it is not meant to work so the CPU dies quickly and you buy another one as soon as possible. As an answer to your question It works towards ruining the CPU as soon as possible.

[@floridaapplemacprosinc.2224]

wow, and yet apple has one of the WORLDS greatest customer satisfaction indexes... just because you dont understand it, doesn't mean it doesn't work. know how your tv works?? no. you use it dont you?

[@estebanquito356]

3:15 It is actually very simple: the only air intake on the macbook is right in front of the area of the SSD, on the bottom left of the image. WITH the back cover on, the cool air enters through the air intake, travels all the way through the logic board, takes all the heat from the cpu aluminum heatsink, gets into the fan intake, and it's propelled out of the machine. The fan creates and area of low pressure in it's intake, that makes the air circulates to the whole laptop. The only difference is that instead of blowing cool air into the heatsink, it's sucking its hot air away from it. If you take the cover of it will overheat to itself death, which makes it harder to work on when testing than previous models.

[@matthias3219]

But if it was efficient even when the cover is on, the overheating issues at normal use would not appear

[@majong_da]

I think that the engineers (or rather, those degraded remnants of them (under the influence of marketers and designers)) expected that air circulation would occur in a closed case. a very stupid decision to make the cooling semi-passive, especially considering that they use Intel 14 nm processors

[@popcorny007]

It probably works using the bottom cover to direct airflow, plus a few thermal pads. Still an incredibly inefficient design, there should be no reason to attempt negative pressure cooling in a laptop

[@Th3OmegaPoint]

Perhaps the bottom case plate is designed to be part of the cooling and make the connection between fan and heatsink?

[@messaoudi_karim]

هذي تصرالي نهار ربي يباركلك في نهارك، الحاجة لي تمسها تتصلح وحدها ولله الحمد

it has a relation when you put the cover on then it creates a small chamber and cools it.put the cover on and use the thermal camera again.

[@thanhthoai]

I think bottom cover work for heater transfer. And intake of fan take way of hot and blow out the vent. This’s precision design.

[@arsayu]

Bottom plate is touching heatsink so whole bottom plate is heatsink. Because of that fan is not directly pointed to cpu because it needs to spread air on as much as it can on bottom plate.

[@PghGameFix]

Since COVID, my electronics hobby has grown to repairing retro game consoles for a local used store. I've enjoyed your videos, and I especially like you shirt in this one. LOL.

[@BoomBeench]

I'm pretty sure the back cover needs to be on for it to cool "properly". But it's absurdity to not including heat-pipes that lead to heatsinks in-front of the fans, I'm sure that this thermal throttles enough for it to work, but if it had proper cooling it could run that i7 at a bit more than 1.7ghz lol.

[@ShadowEli94]

Alex, where can I send a tip or bottle of Whiskey or something. I just replaced a full top lid and LVDS connector on one of these and was stumped by the same symptoms after the repair. I reopened it today and the dang battery was only halfway plugged, just like your case here. I just got that customer his MacBook back and he was very happy. On another note, why do the fans ramp and act like SMC issues when the battery isn't fully plugged? I don't recall older models ramping when there's not a battery connected.

[@nigeriaemploymentopportuni7942]

great video, please I need a link or hw to get the amp meter.

[@eldrinbanaag]

as you said the customer change or replace something there and they did not put it back on properly the battery and i suspecting the customer accidentally cut the heatsink

[@nilomyki]

I thought you would have rechecked the Heat sink after reseating the battery to see if it's still get as hot as previous.

[@stefanlechner]

I have also a 2020 16“ modell, the fan is spinning soon when you work on it. I also think its designed heatsink including the bottom cover. And yes it would work much better with a heatpipe going through the heatsink and the fan. I would love to hear an answer from the apple designers why they built it up like that. It was a fast fix👍

[@userlevel61]

why do you cut the video at the final point???? I had seen many of your videos and you did same thing. In this video why did you cut at 8:16? Was it really necessary?

[@moriambar6533]

How could the battery bad connection cause the overheating of the processor and the spinning fan?

[@earumamaadu]

Those are 2 different problems.

[@nickabbott4411]

I've seen weird things like this when the cmos battery is dead. The motherboard can't read the temperature probes for some reason so defaults up to max fan speed. Also, it may store the temp somewhere that the cmos powers and no battery or cmos causes the fans to spin at max.

[@БабушкинДмитрий]

Without battery macbook starts in emergency mode.

[@maklogetrich2378]

I thought ASUS designed worst heatsink and fan, but this MacBook is clearly the winner here

[@mircomputers]

[@anindyaghosh1514]

It might be so that the bottom lid had metals that would extend from the cpu heatsink to the fan and control the thermald

[@simbashuvo]

[@kkathulgangadharan2262]

Cooling only work with the bottom cover in place.the fan will in take fresh air to device the path of air flow will through the heat sink

[@pjtruslow]

the fan exhausting air would create a draft through the inside of the device, cooling everything somewhat. I am not saying it works well, but fundamentally it should at least work a little bit, though definitely not nearly as well as a fan blowing directly over a heatsink.

[@gluetech4377]

[@SpiderCollector000]

I worked for a Fortune 500 company just before Covid knocked me out of work.. We used HP and Apple for the most part. The new MacBook Pro laptops were nothing but trouble, between the overheating, and the shitty keyboards that they used from 2016 and on. They literally designed the laptop so that you could not easily replace the keyboard, so Apple would just change out the upper palm-rest assembly with a new keyboard that had the same damn defect. Then when people ran out of Apple Care warranty, it would be over $700 to repair, yet there was no shortage of the fan boys. The 2015 and before models had better keyboards. Apples response to the keyboard issues in 2018 was to install a silicone membrane to help keep out the imaginary dust they claimed was causing the issues, but the otherheating was actually causing the scissors underneath the keys to warp, and Apple just would not admit fault and fix the problem until they were getting sued left and right over this. They are great machines if you get the right model without the design flaws, and use them in home or in a small office. In a large corporation, they were a fucking nightmare between the filevault issues combined with MDM via Jamf, and all the other bullshit that I could not get fully into without writing an essay. Lets just say, we got brand new 2019 MacBooks that were defective out of the sealed box.. Countless amounts! It was beyond frustrating to set these laptops up, and then have them fail a week later, and corporate policy had these Macs locked down even more then the PC's so we were literally stuck having to transfer files (when even possible) over the network between the systems. I have been in this line of work, and doing hardware repairs in Los Angeles since 1996 before I even got out of school when I started my own business, and have pretty much seen it all, and know of Apples bullshit antics, where the so called Genius Bar would turn people away if they did not want to spend the money on a ridiculous repair or a new machine. And yet, people still worship these polished turd's.. At least its good money for people who repair them, as long as they are Apple authorized so their mafia does not shake their business down. I dont work on as many Macs anymore, and focus primarily on PC's instead where there is more freedom, and its easier to get more parts with many more options!

[@luisagonzales1442]

It uses the cover,once its on it seal channels

[@gaggioaxel]

Probably apple designed the back cover to be a kind of heatsink that spreads heat and at the same time touches the heatsink cooled by the fan, to save a dollar for the heatsink and 2cm^2.

[@CCellService]

So did you find any solution for this overheating problem.? Apple service center just ignored my email that i sent regarding about this problem, I'm to scared to power on but i need that mac to do work

[@peterwong2465]

Am surprise it's not covered by warranty? Anyway... still a great show. I am amazed how works are being worked on. It's not easy using a microscope to perform such tasks. It's up to open heart surgery level of dexterity.. Good informative works...

[@jadaojaz8882]

The bottom cover is supposed to bring air fan to the CPU. I am not saying it’s good. Just noticed that when you put back the bottom cover the air will be forced to the right of the fan toward the cpu.

[@TotalneRozczarowanie]

I think the CPU cooler works by circulating air. The fan blows the air sucked into the housing from the opposite side.

[@tonytrilex2555]

if they said there was liquid damage why would you even turn it on, I would first do a visual inspection see if anything points out at me and then if the board looks clean upon inspection give it a ultra sonic bath and then start working on it.

[@TheWaLeK]

He does inspects the board first when he starts to record the video so that he can talk about it then he lets us to see it again

[@rexeffect7122]

Maybe the bottom cover of the laptop helps the regulation of the air flow to the cpu.

[@salahadidi3273]

The cooling draw from the air from the mac case to outside and the enter it from the parallel side if you consider the cpu as the center, before reaching the fan, the air pass on the heart sink, but there's no way this disign will cool such a hot processor.

[@CoffeeOverload]

Upon doing a CPU test on a working A2179, the conclusion is the fan serves no purpose. If the fan was sucking air past the heatsink, then air blowing out would be warm or hot, instead of cold. The bottom part of the case gets warm and hot as the CPU heatsink heats. Adding external fans, such as a laptop cooler, does increase the speed of the computer as the CPU receives the necessary cooling. Conclusion, either the CPU is designed to operate using natural convection only with an acceptable CPU loss of life (to get the computer past the 1 year warranty) and/or the fan was added to deceptively make the end user believe the CPU was receiving forced convection cooling when in fact the computer was not.

[@Wingedmechanic]

Knowing what they did to mimic tactile fedback of home button press, I would expect them to remove the fan altogether and rig the speakers to play fan sound. This looks more like a forgotten heatpipe.
