iwlwifi_1-virtual-0 is the wireless adapter and pch_cannonlake-virtual-0 is the platform control hub. PCHs tend to run hotter than CPUs. According to these threads issues don't occur until you exceed around 80C, so at 62C that seems fine.

"iwlwifi_1-virtual-0" refers to a small M.2 form factor Intel wireless module (card) which should be replaceable. If you look on the back of your motherboard, there is a silver rectangular box where the wifi antennas connect to. This houses the physical wireless module inside, it is not a virtual device. On some boards the wifi card is exposed visibly.
To answer your question directly, the operating temperatures for those Intel wifi cards are rated up to 80C. 63C is fine. There isn't much you can do to decrease temperatures since the module is housed within the metal shroud so it's not like your case cooling is inadequate or whatever. It's just how the manufacturer designed it and as we well know, they don't always take into account these little concerns about specific component temperatures.
The wifi cards are replaceable if you do happen to burn it out for like 20, so I honestly would not worry about it. There should be two screws holding the casing together on the bottom of the motherboard to take that whole assembly apart. Some motherboard BIOSes are weird and lock out using other wifi cards other than directly the original model, so be wary of that as well.

I can tell you roughly what these sensors are, if that helps:
eth0_dsa0-virtual-0 is a temperature sensor on the eth0 device, that is, a motherboard or card LAN adapter.
You have two chips on an I2C bus (slow simple serial bus), probably both lm75 (and you made a copy-and-paste error for the first). That's a simple temperature sensor chip. From the temperature displayed, somewhere inside your case.
The thermal zone is something defined by the BIOS. The value is below room temperature, so something seems to be wrong.
It doesn't look like you have installed a driver for your CPU temperature.
In the end, the only person who knows exactly what components are in your computer is you, and we can't guess what's in there. Figuring out the exact hardware is a bit of a puzzle, it takes reading all hardware manuals you have (motherboard etc.), looking at the chips you can see on your motherboard, googling for them chip identifiers, finding the missing drivers, etc.
Edit
Yes, 48 and 49 are the addresses of lm75-i2c-0-48 and lm75-i2c-0-49 on the I2C bus, though I'm not sure if it's hexadecimal or decimal. Both are on bus 0. Look at /sys/bus/i2c to see your I2C busses and devices (only present if detected by some kernel modules).
This one-liner displays temperature:
paste <(cat /sys/class/thermal/thermal_zone*/type) <(cat /sys/class/thermal/thermal_zone*/temp) | column -s $'\t' -t | sed 's/\(.\)..$/.\1°C/'
Here are the results on Intel Skylake i-7 6700 HQ:
INT3400 Thermal 20.0°C
pch_skylake 91.0°C
SEN1 67.0°C
B0D4 61.0°C
SEN2 60.0°C
SEN3 68.0°C
SEN4 71.0°C
x86_pkg_temp 63.0°C
The packages sensors gets it's information from the kernel /sys/class/... directories. You can get all info there which sensors is massaging to reveal to you.
NOTE: pch_skylake temperature is abnormally high on most machines. A short google search confirms this.
+72.0°C isn't too high. If the temperature does get too high and the fan does not kick into action the kernel will try to throttle back the CPU so that the CPU does not hit the critical trip point (this is known as passive cooling).
In theory, the fan will kick in at some firmware controlled trip point and if that is not working the kernel will start to try various passive cooling techniques - so you may notice the CPU gets sluggish if that happens because the CPU frequency gets scaled down.
I believe that modern Sandybridge CPUs have a TJmax critical thermal threshold of 100 degrees C, so your system should work OK in the upper 90 degrees C without much to worry about.
My sensors output:
I have MSI GV62VR-7RF. This is a normal temperature for pch chips; it would be running at the same temperature on Windows. So it's ok for your laptop to have pch on 72 degrees.
>80 degrees is high and >90 degrees is harmful for pch chips.
My MSI laptops's pci is running on almost same temperatures for both windows and Ubuntu. You should not worry about it.
Note: my laptop runs at 70 to 76 degrees pch temperature on boot, while after 1-2 hours it drops to 66-70 degrees.
Also install powertop. by sudo apt-get install powertop
and run sudo powertop --auto-tune on startup it will keep your pch chip much cooler.
Hi, I just purchased an ASUS z390m TUF motherboard. I'm enjoying it so far. I noticed in my control testing and benchmarking (stock settings) that while all my temps are sub 30°c~ish my PCH temps are 85°c idle. They raise a bit under load.
I can't find documentation online that shows the temperature specifications. So I'm reaching out to you good people. What is the limit, should I be concerned?
i5-9600K is like 30° idle, 65° underload.
