I recently bought the Macbook Pro (2018) base model with the following specs –
It overheats. The exact temperatures of each location are given here [
but the laptop is generally uncomfortably hot to touch.
From the tests you made we can eliminate a list of potential culprit candidates:
internal disk: use in target mode
but you might be tougher on this test:
in target disk mode fire Disk Utility and perform some (ex.: 4)
Verify disk one after the other.
OS: re-install by an Apple service center
Here are the remaining candidates:
If your problem is just due to a graphical chain problem, your system might be correctly booted, but you can't notice it. To check this probability, you will have to set your Mac so as to be able to remotely verify that it is alive or dead.
Connect the bad Mac to a good one with an Ethernet cable,
Boot the culprit Mac, even if it does just show you his blue screen,
Open a Terminal on good Mac, and get the broadcasting IP address.
The following command will display it:
ifconfig en0
behind the keyword broadcast (3rd line).
You may also get it at first with a slightly more tricky command:
ifconfig en0 | sed -n 's,^.*broadcast \(.*\)$,\1,p'
Let's say that it is broacast_IP (most probably it will be 169.254.255.255).
do a ping broadcast to see how many Mac are alive:
ping broadcast_IP
if this command reply you with 2 different IP addresses, then you can conclude that bad Mac is alive and its graphical chain is dead.
On the other hand, if you only get a reply of your good Mac, then bad Mac is really dead, and the last culprit is the good (i.e. motherboard).
Judging from the stats you provide, it seems like it may be a CPU-related issue. Try to investigate this further to understand better if the issue is RAM or CPU related.
To determine CPU use, go to Activity Monitor and press cmd+2 to get the CPU usage graph. See if one CPU is peaking during these operations or if it is multiple CPUs.
According to Geekbench, your MacBook Pro actually has pretty decent performance, however the newer model that you have in mind, would be 15% faster for single-core operations and 46% for multi-core operations, respectively. Moving to an iMac could offer a performance boost of up to 34% and more than 100% for multi-core, respectively. Since you are considering to move to a stationary iMac, you may also want to consider the Mac mini. It currently offers the most "bang for the buck" as it is cheaper than most iMacs. You can even save more money by installing additional RAM yourself (which requires some tinkering) and use external drives via USB-C.
To diagnose RAM usage, have a look at Memory Pressure, which is indicated at the bottom of the Activity Monitor app, when Memory is selected. If it is yellow or red, adding more RAM may actually help.
In addition to that you may want to have a look at Adobe's guidelines on Illustrator performance. Finally, there seems to be / have been (?) an issue with performance on your model and users reported that disabling the dictation feature in System Preferences > Keyboard > Dictation helped.

Your average body temp is 37.2 Celsius !
I do not see any surface area on your Laptop that is higher than 38 C, so you would not feel it as hot.
As for the diverse electronic devices and Integrated circuits (CPU), they are designed to withstand up to 110 Celsius.
Your Mac will turn off at 105 C.
None of your results come even close to been HOT.
