Cooling Solution for the 2018 MBP

there are plenty of other components in the enclosure that are much more sensitive to heat

Yes, but the heat they're being subjected to isn't anywhere near the temp of the CPU cores. The laptop as a whole will have a set of design characteristics with thermal limits and so on, and as a whole it will also follow those specs. Apple's quite capable of doing that... :)

Evidently they're not, since we have multiple threads and discussions of throttling ;)

I'm of the opinion that higher temps is bad for electronics and the more I do to reduce the temps, the better my Mac will be imo.

Yes except like I said, throttling isn't evidence of overheating. It helps if everyone gets their definitions right (and maybe also cut down on the hyperbole, but I know that on the internet this is a hard thing to ask for lol...)

Also in general you are right, electronics like lower temps (within reason) than higher, but there's also the thing where you will just stop using your device before it has a chance to die on you because your 90C CPU heated up the interior of your laptop slightly more than it would have if it had run at 75C. :)

I never said 'nobody', I said 'a vast majority', and that still holds true today. The fact that Apple is selling 32Gb doesn't mean people actually need it. Apple will sell what people want to buy, and most of those people will buy it for the wrong reasons. Apple is happy to take your money.

For a small amount, 32 - and even more (a lot more) is really needed. For those, it's good that the option exists.

Again, for the vast majority of people, professional or not - 32Gb is a serious overkill. Same with i9, honestly. I stand by what I said. People claim they need 32Gb because they open a lot of browser tabs. That is just wrong. But hey, how you spend your money is your thing.

But in the present case choice to upgrade is not the issue. The problem is the upgrade doens't work right. If you bought 32GB RAM but could only use 16 when the machine runs hot - would you accept that? No? So folks paying top dollar for a CPU upgrade should not be satisfied with throttling either.

And before you react. Look at the improvements achieved here. Users -example maflynn managed to improve the benchmark scores from 697 to 869 in a few mins downloading a tool to tweak the setttings. Thats a 25% increase. Tell me this - should a premium device be so badly configured at purchase that users can so easily improve it with some amateur tinkering? NOOOOOO. Apple goofed here. Stop defending that.

Edit:
I'll say this too. I'm not sure which scenario concerns me more: 1) Apple didn't do the necessary testing to detect these throttling issues or 2) Apple did do the testing but shipped it this anyhow.

I think the hotter idle temperatures (as per Linus tech tips) are probably more worrisome than even the throttling given some were thinking the pattern of keys failing linked it to heat...

I've reworked the Volta app with power limiting and I'm seeing better results. I can better manage how much performanceI want with the level of heat that comes with it. I think we have a winner and I'll update the my OP to include the link and reference.

You should make reference to the original source of this recommendation, which also includes performance testing that shows the degree to which it addresses the issue.

Checking in here with a maxed out 13 i7 2tb 16gb, creating smart previews for a 700gb adobe lightroom CC library I was throttling with 99C temp and average core speed of 2.5ghz (2.7ghz is stock). I tried Volta and made no changes besides setting 28w to the max draw; the same procedure gave average core speed of 3.2ghz and 90c. Works for me. Thanks. Can't wait until undervolting works for even more performance.

i didn't read that article, Another member @Feenician asked if I could try that app, as I mentioned another app (Turbo Boost Switcher) When I did read it, I totally missed the part about that app

Understood, but this article has been mentioned quite a few times over the past couple days on this forum. Just the prior page of the the thread you link to has it referenced 4 times.

If you're trying to provide your members with the best info in this thread, it's probably the thing that should be at the very top. It is, after all, the source and verification of what should be seen as the proper fix. Turbo Boost switcher is a relatively poor bandaid and probably is best stricken from the discussion (yes, it's free, I get that, but Volta is an insignificant cost for $$ laptops).

Principle is great, but I already bought this machine and it's not going back. I need recommendations for a cooling system that I can buy for my home and work desk that will allow the cpu to run max turbo boost. I am tired of getting talked down to when I ask for this. Yes, I agree Apple should have provided a system that did so ahead of time. They didn't. And I dropped $4k on it anyway because it better satisfied my needs than did anything else.

So, who knows a good cooling pat/matt that actually drops cpu temps?

Man, apple loves this type of customer.....

It was, but I searched and couldn't find it *¯\_(ツ)_/¯

Thanks for posting this. This is giving me some hope that a firmware fix could alleviate some of the issues.
Have you still turned off Turbo Boost as well? Still not sure if getting the i9 is worth it, but the i7 could still get the job done.

Have to admit I was one of the people who was verbally very pissed at Apple. If they can sprinkle some unicorn dust with a firmware update and fix some of the issues, I'll take back all my comments.

I found that setting to be superfluous once I limited the wattage. That is Turbo boost is boosting the clock speed beyond the rated GHz, but if you limit the wattage, then you're preventing turbo mode to an extent.

Make sure you pick this up for your business while running the macbook....

We've got a full commercial grade kitchen in our break room, I will just have an employee run my macbook to and from the freezer occasionally. You really need to think bigger.

Even with all that throttling, the i9 MacBooks and XPSs are the most powerful laptops of that size. If you want more power, you need to go bigger, that's physics. But do you really want to? Everyone here claims they do, but most of them actually don't. This is called 'whining'.
Click to expand...
Actually, that's not true. Because of hardcore throttling, the i9 MacBook Pros are actually running slower than the i7 models in many cases.

That's a pretty legitimate concern.

Like most of the drama on these forums, this is a non-issue for most people, especially for i7 owners. Returning the laptop for this is, in my opinion, silly - unless your work really requires you to get the maximum theoretical amount of available performance from a computer that just has to be a laptop. But in that case, you should probably get some 17" HP mobile workstation.

Or maybe Apple can retreat from their "thin at any cost" product offering and go back to what was working fine. My 2012 rMBP doesn't throttle under load.

So I know this may seem like a stupid question, but being new to the idea of actually manually turning off/on the Turbo Boost functionality of the Intel chips, is there any possible side effects or issues from using an app like the one you listed to shut off Turbo Boost (other a possibly slowing down some performance of course). While I don’t have a 2018 model, I’m curious to see if this would be beneficial at all for my 2017 MBP.

Also does manually manipulating the chip functions void any of the AppleCare warranty?
 
My 2018 13" i7 16GB MBP runs very hot doing basic stuff.
Things like Time Machine Backup or downloading an update gets the fan running at max power and the metal above the touch bar is unbelievably hot.

Thought there was something wrong with it but from the sound of the forums scaling hot is normal operation.

I'll get Volta a try setting it to 28watts max, hope that reduces how frequently the fan has to go into jet takeoff mode.

Thanks for the advice.
 
Just return the machine if it's not working as advertised.. you shouldn't pay so much for the extra horsepower and then disable it.

In my country, Apple doesn't even accept return unless for obvious DOA cases... It's totally backwards (due to the scalpers).
