to find out what gen intel cpu you have (on windows, idk how to do this for mac or linux, i'm sorry) go to your start or search menu and type in device manager:
In device manager, look up processor:
Mine is a 12th gen, so I am safe from this bug.
Now, I haven't had a chance to watch the videos, so sorry if I am reiterating things here, but because some people learn better with text:
How to read intel CPU product labels for intel CORE processors (this is the most common intel cpu you are likely to find for home pc and laptop builds, their other cpu product lines are more for servers and ai and people who still use 32bit OSes, which are largely obsolete now):
the first letter number combo is always i and either no number, 3, 5, 7, or 9. The number refers to the amount of cores a cpu has. In general, more cores, faster cpu. (there are other things that affect cpu speed though, mostly clock speed. This is usually listed in ghz on the product page, but it's not relevant here to determine if you have one of the unlucky broken cpu models.)
In this example, I have an i7, which has more cores than an i5, but less than an i9.
The first 2 numbers after the i number is usually what generation you have. Sometimes, depending on how old your cpu is, it's only the first number. Mine is a 12, so I have a 12th generation cpu.
The numbers after that are the SKU numbers and largely are not important.
The letters determine if your cpu has onboard graphics or needs a discrete graphics card, and if it comes with a cooler/can be overclocked. (i personally do not recommend overclocking because a lot of software isn't really designed to support it and it can cause problems) If it has an F, it means you need a separate graphics card. If it has a K, it means you can overclock it, and also that it does not come with its own cooling.
Laptop cpus almost always will come with their own cooling because laptops get really hot and cooling in laptops is kind of abysmal to begin with.
If you have a LAPTOP, and your intel cpu is 13 or 14, you will have to replace the ENTIRE LAPTOP. start making backups of all your important information ASAP. Due to how laptops are constructed, you cannot replace a single part, you have to replace the whole machine. If you have a PREBUILT desktop, if you can figure out what motherboard you have, you may be able to buy a replacement cpu. If you build your own desktop, you are definitely able to replace your cpu.
A cpu is attached to your motherboard - if the cpu fries, it can also damage your motherboard as well, so if it's at all possible, and you're ended up with one of the broken cpus, I would look into replacing the motherboard as well. (Again, if you have a laptop, you need to replace everything. Sorry.)
