Not taking any sides here but Apple do have a monopoly on Apple devices. You cannot side-load software on an iOS phone, unlike with Android. Not to mention that Apple also holds a ~30% market share in smartphones.

Try blowing it out with compressed air, if that fails then most likely the fan is going to need a replacement of either the same size (I am guessing 120mm) or another fan configuration supported by your case.

He isn't streaming, he's recording, so bandwidth won't matter as much, only when uploading.

I think your limiting factor here would be storage if you plan to record extended gameplay in 4K, 60 FPS. Also, if the game you are running is very graphics intensive, you might see some stutter here and there.
 
There are some tutorials online teaching you how to record in 1080p, 2K or 4K, just check YouTube.

It's alright for it's price but if you wish to add a GPU or upgrade in future, the current PSU will probably not be able to handle it since it's only 250W.
 
As for OS, you should just stick to Windows 10 if you don't plan on programming.

There are some good value prebuilt systems out there, but in general, building your own is cheaper, especially if you know where to find good deals on parts.

Access your router's settings page and check to see if your computer shows up on the list of connected devices. Then, see if you can release or renew the connection. Make sure to "forget" the network on your computer too, and ensure that your WiFi card is running the latest drivers.

In general, mail services all over the world are being disrupted. If it's stuck on "label created" means your package has been registered into the USPS system but either hasn't reached a sorting hub or hasn't left the LTT warehouse.
 
There's an alert on the USPS site for Germany:

Doesn't sound like your cooler is mounted properly. You might have also snagged something while messing with the cooler. Remount your cooler properly (patiently) and make sure all other connections (such as your GPU) is mounted properly too.

To add to what @Quackwich said, try running ddu. I love this video as it explains it great: 
 

Check your NVIDIA settings (right click desktop -> NVIDIA Control Panel). The new driver might have reset your NVIDIA settings. Make sure you're using your dedicated GPU and not your integrated GPU.
 
If not, uninstall your driver using DDU and install an older, more stable version.

He is that's the only thing I can think of would be a memory leak. In which case you should go back to main "stable" windows.

Ubuntu 20.04 is actually a huge upgrade to default 18.04, because it uses the new Linux 5.4 kernel. 
The new kernel brings in exFAT support, GPU improvements, more platform support, thunderbolt support, VirtIO-FS for those using QEMU/KVM, and lots of general fixes. 
For me the new Linux Kernel has so many changes it actually breaks my Nvidia/Docker so i'm unable to upgrade my Plex Server to Ubuntu 20.04 currently. 
 
Most of this means nothing to the OP. You can update 18.04 to the new kernel by applying the HWE update, but default theres a big difference in the kernels (4.15 > 5.4). 

Can't imagine any actual improvements. Its mostly some smaller changes. A lot being visual.

If it works, don't fix it. (besides security updates ofc)

For RAM, 2400Mhz is slow for DDR4, you're better off buying higher speed RAM than overclocking it.
 
What GPU do you have?

Would be nice if we could have Steam embeds that show the game title, price and description on this forum.

Leaving the battery at 100% capacity will decrease its lifespan, but running it through repeated discharge and recharge cycles will also decrease its lifespan. Basically, whatever you do, your battery will wear down and lose capacity, that's just the drawback of lithium ion batteries right now.

I don't have a .edu email, but an email from my university with a different ending. It's also eligible for a Student Beans account, so that would also work.
