hello! yesterday I just got a MacBook Pro Non-Touch with 8 gigs of memory and a 256gb ssd. Since i will use this for the next 6 years, I need to make sure this thing will be reliable. But then in the first day of using it, I preparing an opening essay when my mac starts going crazy at safari with 3 tabs opened. I checked iStat and my fears are confirmed, my cpu is at 90 degrees. I was doing this in an air-conditioned room a flat table. any idea to whats going on? My cpu load is at 25% with no background apps, except for MS Word itself.

My laptop was in repair for a week so I bought the one just like yours to use for that week and I was blown away that I could not do tasks I did on mine like having about 20 tabs open with essay page and few more things. This one was just lagging and fan was going hard, so maybe its normal? I really hope its not though...

Best advice is to take it to the apple store and while you're still under the first two weeks, they will most likely replace it

Do you think this is a software or hardware issue? I live quite far from an Apple Store. Also, I literally just read YOUR thread. sorry I cant put any input at yours:(

No need to input in mine as you don't have these problems :)

Not sure what the problem is, I'd say give it few more days or so as you have 14 days and just see maybe it will improve or something
 
The non-touchbar model has only 1 fan vs 2 on the tb.

Cpu load of 25% suggests that some process/thread is constantly running at full speed. Find it and kill it.

P.s. I'd try getting the base tb model.

25% of CPU load means that a CPU core is maxed out by some running process, so it's not surprising that it gets hot. The way how CPU utilisation is reported is rather confusing unfortunately.

1. even if I could refund my mac, I really need the extra battery life. 1.2. I wasted my money on an eGPU thinking the non-tb was enough. I cant refund the eGPU.
2. that makes sense now, since the single fan is working really hard (6000 rpm)
3. the CPU load was caused by the website itself. I'm trying to find the cause, since its just google doc.

While you logic is sound, I don't think that is correct. If one (out 4) core is fully saturated then 100% would be where all 4 cores are saturated.

However that's not how its counted. thanks to hyper threading, and what not, there's no way to say 25% is a single core reaching full capacity. Just look at the results of PRIME95 running, I'm hitting 1,051% which makes no sense ¯\_(ツ)_/¯

It all depends what you are using to monitor CPU. Something like istat menus in certain places gives 25% to each thread consuming all cpu on a dual core with HT.

Good point, I was using macOS' Activity monitor but even top in the terminal shows the same thing as the activity monitor. I don't have iStat menus running currently so I can't test with that.

You need to look at total CPU utilisation in the bottom. Activity monitor is not very consistent how it reports this. In per-process column, it reports CPU utilisation interns on a single CPU core, while as a total, it looks at the entire available CPU time (which includes hyper threading cores). E.g. if I max out a single core, the activity monitor will show 100% for that process but 10% of total CPU utilisation (that is for a 6 core CPU with 12 virtual cores).

I tried, but the load was caused by the website itself. Does the on-site video in the site make a difference?

Could very much be if it uses custom script to decode the video using the CPU.

Everything the website does can make a difference. Including ads, video, stealth cryptomining, etc. The site can use scripts that can utilize you system's CPU and GPU just like a "normal" program such as Excel.

that makes sense. should i pay for no ads?

well, I checked, the results of activity monitor and istat is different. the 25% I got was from istat (for comparison, restarting takes 75% cpu power.)

now I'm officially worried: https://forums.macrumors.com/threads/2017-macbook-pro-13-non-tb-review.2056971/
