I know it will void the warranty but after watching this video I am tempted.

I run several real time data feeds and several live videos at the same time and it gets HOT!

I don't think I experience any throttling bc it's still fast, but it does get hot.

After watching this video I feel like maybe it can run cooler.

I read somewhere that they started putting better thermal paste in the 2019’s to avoid the same thermal throttling affecting 2018 and below.

It might not be worth it.

I did not know this.

All I can say is you can leave it to Apple to cheap out on Thermal Paste until they have to spend a nickel more bc of customer complaints. Ugh :confused:

For thousands of dollars, come on Apple. Give us the BEST thermal paste!

So true. Spend $.50 now to save endless thousands of dollars in repair costs because of overheating. I never even took a business class and I know this. You would think the extremely well paid engineers and executives could figure this out. Or maybe they should give me a sweet $250K per year job to tell them stuff like this.

Bottom line: There are simply zero excuses for not using anything but the absolute best thermal paste available on planet earth. Heat is the number one destroyer of sensitive electronics. Along with dust and water, of course :)

Could be this, but I think they're actually undervolting their CPUs now. As Dave Lee said. It's usually the better choice, because I don't think the thermal paste on the Macbooks is worse than Windows laptops, plus it's fairly a new model, it's not been a year for the paste to wear off or whatever.

I think it’s both.

Definitely undervolting. Linus Tech Tips did a video and the 2019 still throttles like crazy under Windows.

Wrt thermal paste, IIrc, maybe Snazzy Labs’ videos mention this? Or Linus Tech Tips?

My 4 week old 2.3 15” 2019 reached a hundred degrees Celsius all the time. After an Apple thermal replacement it is around 100 points higher in Cinebench R20 now, however , the temps are only 1 degree Celsius lower. I am wondering what would happen if I put in Kryonaut paste.. on my MacBook Pro 2015 this paste helped significantly and brought the temps down by a lot

You got the right channel but wrong video. Search 2019 MacBook Pro on youtube and you'll find a few saying the thermal paste is better and do not open and try to add your own.

Like many have mentioned, the 2019 seems to have better thermal paste already. If it were 2018 or earlier, then I recommend going for it, assuming you are confident in doing it yourself.

Yeah heard about the same from certain folks who repaired the 2019 models thus far.

That’s a terrible “advice”. You are much more likely to lose money because of incorrect paste reapplication, and of course, your warranty will be void. The only reason to reapply thermal paste is to increase the performance potential of the machine.

Different CPU with different turbo boost profile. A MacBook Pro is designed to push the CPU as far as it will go - meaning that the system will always try to go to its thermal limit (unless the over locking limit is hit first). Since newer CPU will draw over 100W on turbo, improving thermal dissipation will simply push the limit a bit further up.

That’s not entirely true the USB-C has a 100watt limitation so many times it’s not a cpu thermal limit but an entire power limit. They are not pulling over 100watts total let alone CPU.

The limitation is not USB-C but the max discharge rate of the internal battery. But that's besides the point. Maximal CPU power draw I've seen on my machine was somewhere around 87 Watts. And of course it won't sustain it for longer then few seconds, max. I was talking about how power-hungry these CPUs in general, not necessarily in the MBP chassis. The point is that they can draw much more power than the older SKUs and f you give them some thermal headroom, they absolutely will.

The OS makes it USB-C restricted not battery. The book will exceed 100watt for a moment until it realizes its operating at a net negative and it throttles. It will always charge when plugged in. Batteries are all capable of exceeding 100watt discharge. Most non-usb-C do so. They are all the same type of battery

^ Even for peak performance? (genuinely curious)

What does Intel Power Gadget say on the 2019’s?

What I meant was for APPLE to spend the extra .50 cents for cooler operation and to save the owner from having to even consider replacing the paste :)

Finally, we have good thermal paste haha. I still can't believe Apple couldn't spend an extra 5 cents on THERMAL PASTE!!!

I have changed the thermal paste on my macbook air 2017, it was fairly a hard proccess but was totally worth it, it was 8 months old when the thermal paste dried and was touching 105 degrees celcius while playing minecraft and video editing, after which it used to throttle, I just put some thermal paste on the CPU (MX-4), done, problem solved, no throttling. It touches 95 degrees at peak load of tremendous 4k video editing and i also turn up the fan speed to 6500 while playing and editing, yes, also, i cleaned the dust inside, the fan was clogged up with dust. But with that 2000 dollar ****, I would recommend it getting done by a professional, I got mine just for 650 dollars in black friday sale, so i tried it, also, I already had all tools and thermal paste lying around from my last project (My gaming PC). If anything goes wrong, you are done for, I have seen the extremely small parts and small wires inside, i had to read the iFixit guide 5 times to remember where the parts and wires belong to, writing this from my MacBook Air 2017 itself, also it improves performance by a whole notch. Cinebench Before: 272cb + 29.76 fps, Cinebench after: 296cb + 33.54 fps (With Windows, MacOS sucks :( ). On MacOS, I get low scores :(, before: 270cb+ 28.34 fps, after: 278cb+29.32 fps. lol

Apple used to put way too much thermal compound in the older models, but the new 16-inch looks OK from the iFixit tear down photos.

"Will changing the thermal paste on my 2019 15" MacBook Pro make it run cooler?"

Probably not.
You'll end up with a hot MacBook and a voided warranty.
