There are two ways to store map tile data like OSM. One is as pre-rendered raster tiles (256x256 png images) and the other is as tiles of vector data that get rendered either on the fly by dedicate rendering middleware or rendered client side by the browser. Vector tiles are anywhere between 20-50% smaller that corresponding raster tiles. Raster tiles was the standard way of doing web maps up until a few years ago, when client side rendering in the browser became feasible and now most people use vector tiles.
As a 12 year old: I tried to overclock my first "good" own computer (AMD Duron 1200 MHz). System wouldn't start at 1600 MHz and I didn't know BIOS reset exists.
I ended up putting the computer in the freezer and let it cool down for an hour. I placed the CRT display on top and the power/VGA keyboard cable going into the freezer. I managed to set it back to the original frequency before it died.
You guys are really smart. When I was a kid I had a graphics card that would overheat and crash the computer when I played Lineage. So I would get down under my desk and blow on it...
When I was a teenager my friend would throw his laptop into the freezer for a few minutes every hour when we were playing games. He probably threw it in there hundreds of times, and it worked fine for years.
I don't know why but this reminds me of how we picture-framed my friend's old Wifi chip after replacing it, because that chip failing all the time was basically the core feature of our group's gaming sessions.
Once my phone died from a cracked solder joint. I had cold veggie sausages in the hotel room fridge. Holding my phone against the sausages let me grab a couple more files off of it. Saved my OTP keys that way (I've fixed my backups now :) )
