Here is my story. I've had a base model 2013 MBA 13" for 7 years and it still works ok. But I maxed out my 128gb storage years ago, and lately, I've been doing some zoom meetings and was annoyed I couldn't put a virtual background:) (Which I guess you still can't do with a 2020 i3 dual core?)

More importantly, for the last several months and a couple more months to come, I've been downloading and uploading video files, often a couple of 2gb or more, for a film project I'm working on. I'm not editing the videos, but I'm loading them, sharing them, saving them, downloading them, screen sharing them on zoom, and otherwise constantly doing one thing or another with them, and I've got about 300 gb of these files now spread out in storage on the MBA and two different thumb drives, things sticking out everywhere.

Other than that, I do a fair amount of web surfing and emailing and otherwise wasting time on the internet, and just use Safari. I use my laptop almost exclusively on my lap and want to remain doing so. This is an important part of the story! lol.

So recently I'm thinking it's modern times and there's a pandemic and I'm doing zoom calls and suddenly working with videos all day, maybe it's time to upgrade. And while I'm doing so, why not get some real power and memory and storage as well? So I decide I'll get a 2020 Mac Air, but I'll soup it up a bit for some oomph. So I get the i5, 16gb, 512 model a few weeks ago.

Then I start using it. The thing was on fire! Way too hot on my lap, and the fans were kicking in too. Noisy. And I was only doing basic stuff, no zoom or video action. What the hell? My old 2013 rarely gets hot, and I rarely hear the fan. Then I do some googling, and I see other people have had this issue with the i5 or i7 upgraded MBAs, so I decide to return it.

So I go to the Apple store thinking I'll get either the MBA i3 processor, perhaps with some more memory or storage if I can, or I'll try a MacBook Pro. Whilst there, I decide "Heck, I haven't bought a computer in 7 years, and I want power and performance for zoom and video work and all that, so just go for it and suck it up the cost and I'll fine for years to come". So I get the $1799 MacBook Pro 13", even though I prefer the the lighter Air design, and the Touch Bar seems useless, or worse.

So I get it home and starting using it this past Sunday. And... it runs hot. Way hotter than my old 2013, and this is just browsing the internet. I didn't even do any video stuff. Hotter than the souped up 2020 air I briefly had you ask? No. Maybe slightly better than that. I also haven't heard the fan yet like I did on MBA i5.

So, it's better than the MBA i5 I had, but still a bit too hot for my lap. So... the big question: does the base i3 ever get hot or have the fan kick in often? Sure, I want all the power and storage and all that for my video needs, but maybe I'll just have to settle for NOT having all that, and knowing that at least a 2020 i3 should be a bit better/faster/whatever than my 2013 model, and cost a lot less too.

But if the i3 MBA is gonna get hot too, or have a noisy fan kick in also, I'll just stick with my MBP.

Thoughts??

No stories but am interested in any responses you get in this thread. I’m coming from the 2014 MBA 11 inch base model. It’s still works great but it’s time for an upgrade I think.
 
Could you please post Activity monitor(CPU tab)/Intel Power Gadgets screens from right the moment when it feels hot? Otherwise it is hard to tell what is going on.

That might be above my pay grade in terms of know-how, but perhaps I try.
 
Are there any simple and free reliable apps one can install to measure temperature? I see all these videos on YouTube where people somehow have the temperature measured on their Macs.
 
I had the same model (10th gen MBP 13) as you for a couple months and it ran cool. With a heat pipe it had a better ability to transfer heat over more area. I only went with the air because the pro was overkill for my application and picked up the base on sale and to have less in it to see what Apple Silicon offers later on. Air is a little warmer and that is because of how the heat sink has no heat pipe so you get a warm spot if pushed.

Look into the activity monitor and see if there is a rogue process, do a restart.

I use Macs Fan Control, more straight forward for install than Intel Power Gadget.

So to confirm if I'm reading right, in your experience the 2020 Mac Air i3 version runs warmer than the 2020 MBP? Warmer enough that you felt the need to use something called Fan Control? (sorry, I know nothing about tech or modifications or CPU's.)
 
you felt the need to use something called Fan Control?
Indeed Fan Control is able to control the fan speed, but most of the people also use it just to know the temperatures on various sensors without the actual use of fan controlling. Because it is also free in terms of just watching temperatures.

I see.

But bottom line from your experience: I'm certainly not going to be to getting a cooler, less noisy machine if I return my higher end 2020 MBP and buy a base model 2020 i3 Mac Air, and would likely end up with a hotter, noisier one if I did?
 
I replaced my 2012 MBA this month with the base model 2020 i3 MBA. Can confirm it gets hot during the simplest of tasks. CPU throttling is odd, I don’t quite understand it. For example exporting some RAW photos as JPEG takes forever, up to a minute to export just a few photos, but overall I’m happy with performance. Was video editing using Final Cut Pro in 1080p last night and everything was nice and responsive.

I have been tempted to sell it and buy the MacBook Pro, from what I’ve read it is only the i7 that doesn’t suffer from such bad throttling however I’m sure it still gets pretty hot due to the thermal design.

You're tempted to sell it because it gets hot, and some things take forever? For me, who uses my laptop almost exclusively on my lap, how hot it gets/feels is perhaps the most important issue of all. I didn't even realize it was the most important until my experience with the heat issues of my 2020 MBA! (For the record, I went back and tested my 2013 MBA, and it can get a tad warm after while too, but not nearly as bad as the 2020 i5 I had, or a bit better than my 2020 MBP).

ctjack is correct, I am using just for readings. The 10th gen MBP is one fine machine. Are you in the states? Best Buy and Amazon have it for $1599.

So, same heat issues for you with i3 2020 Air, Supra Mac?

I'm in New York, yes. I just paid $1799 on my local Apple store. I don't see it on Amazon for for that price, but I do see that Best Buy does, and I can pick it up today three miles from my house.... Damn.

Any meaningful downside from buying from Best Buy and returning this one to Apple store? I guess the odds of Apple store meeting Best Buy's price in the form of a refund are less than zero, huh?

UPDATE: Talked to Apple. No price match. So arranged to return this one and purchased same model from Best Buy which I'll pick up this afternoon. Thank you for the tip!

Glad to help.

Enjoy your PRO.

Enjoy your new machine! Best Buy is a good place to buy Apple gear and they often have sales. Their return policy is very good (and gets extended if you create a BB account; there's a couple levels of free membership based on your purchase levels).

ok, here ya go! My high end Pro 13", the second one I've had in two weeks, is running fairly warm on the bottom right now after maybe an hour of surfing, reading, and emailing on the internet. Here's what the CPU stuff says, two screenshots taken a few seconds apart. Can anyone tell anything?

From the one screenshot it posted, it looks like 'nsurlsessiond' and 'cloudd' are using almost 40% of your CPU resources. From what I found, both of those processes are related to iCloud and iCloud Drive. One thing I would state is that Intel has bumped up the clocks on their processors to compensate for their inability to move to a smaller process, so some of that heat would be an extension of the additional power draw the CPUs require now. My activity monitor is quite different from yours:

I haven't had any heating issues with my i3 MBA, and I've had it for a month and a half at this point. The only time it even started getting noticeably warm was when I was applying a series of filters to a photo in Photoshop.

Here are some links about resolving the issues with both nsurlsessiond and cloudd:


 
Sounds complicated for a non-techie like me. The first link I couldn't understand at all. The second was better. I guess my key concern is whether the problem is solvable without taking drastic measures? Second issue will be can I myself figure out how to solve it.

Meanwhile, here's my activity monitor after leaving a couple of tabs open and playing a movie on YouTube for about a half hour. Also, I notice the CPU information changes by the second as I sit there and watch it. I'm assuming that's normal. (Not sure I've ever looked at the
3Screen Shot 2020-08-16 at 6.20.38 PM.png
activity monitor before.)

According to the URLs from above, you are having a Software problem, which has nothing to do with your particular laptop. So exchanging it many times won't help. Yeah, this is an Apple nowadays - it seems like Catalina having problems.
A file permissions/ownership problem stops nsurlsessiond from writing its temporary files.
This is taken from the first link above. Basically, nsurlsessiond wants to write something in one of the folders in your laptop, but the folder is closed for edits, so it is a stuck process.
You either do
Take a look at log files in /var/log/asl. Mine had statements like: libcoreservices: __makeDirectory: 405: mkdir: path=/var/folders/zz/[randomized name]/0/ mode=0755: Operation not permitted.
If that looks familiar, take these steps.
1) In Terminal, kill the parent trustd process, pressing pausing on write attempts. trustd will start again in some hours.
# sudo kill -9 [trustd PID]
2) Remove the old nsurlsessiond temporary directory.
# sudo rm -fr /var/folders/zz/[randomized name]
Alternatively you can find the specific "randomized name" directory by looking for nsurlsessiond ownership:
# ls -la /var/folders/zz | grep nsurlsessiond
3) Optionally, clean up /var/log/asl if this is taking up lots of space.
You're done. Hope this helps.
or reinstall Catalina without restoring from backup.

Activity Monitor is real-time reporting, so it should be continually updating itself. The Windows Task Manager updates in a similar fashion.

If it's not unique to my particular laptop, this would mean every person with a new MBP and Catalina should have this problem, right?

If a fix any uninstalling and re-installing, I may need to call Apple support to guide me through it all. And who doesn't love calling them?:)

For comparison, here is what is going on right now, after using my machine to email and read some news stories for a half hour today so far.

Here's another one a few minute later, with the computer again feeling very warm on lap. Much warmer than my 2013 Mac Air would feel doing the same things.

Not every person, but many could encounter this while upgrading to Catalina.

I can not see anything abnormal here.

It looks like nydailynews website is a resource hog. Just for curiosity opened on my laptop and it immediately used 90% of CPU power and stabilized at 28%. Anything above 10% usage of CPU will lead to warm/hot laptop experience on any laptop.
