    Intel's CPU can work up to 100C before throttling, that's a LOT of heat.

    No it's not. It's quite a standard amount of heat that CPU's have experienced since the days of Pentium 3 and the first generation of Athlons. Additionally most of this temperature does not couple into the motherboard where even if your die is at 100C you will read barely more than a 20C rise on the board itself. On the otherhand VRMs do couple heat directly into the motherboard and they are rated to 150C though most of them will sensibly throttle at around 130C mainly to prevent cooking other components on the mainboard.

    I've also seen people over-tighten them, cracking the chip or having liquid leak all over.

    Wow. Someone has been buying coolers from aliexpress. There isn't a waterblock currently on the market where the instructions don't say to just do up the bolts as hard as you can. They all bottom out and use a spring based retention system.

    Crack the chip? I call bullshit. You will do damage to every other component on the board long before you crack a CPU with an IHS on it. Now theres plenty of people who take the IHS off, but your assertion is that we're talking about people who don't know what they are doing. And yes if you're building a custom loop there's risk of leaks, but by your own admission you're worried about incompetence, so why target the enthusiast? An AIO doesn't leak.

    they will dissipate the heat into the tiny watercooler sink which then becomes a radiator to the neighboring areas, melting out capacitors and various other things.

    I'm sorry but physics doesn't work like that. You can radiate from the entire surface of the CPU without cooling and your neighboring components will barely be warm to the touch at the pathetically cool 100C where the CPU will throttle. See the top of my post. 100C is a trivial temperature to work with and we've worked with it for 20 years now.

    The thermal cycles of a modern CPU are no different to those from 10 years ago, we ran them up to 100C back then, we run them up to 100C now. The difference is that a modern CPU getting to 100C on die will cause it to protect itself whereas the old ones happily let the smoke come out.

    TDP limit is a figure given to designers of cooling systems and my ancient Pentium 4 had thermal cycles almost identical to my Threadripper (which has 4x the TDP). Oh and my Pentium 4 still works 15 years later.

    And yes, people will install the chip the wrong way, overtighten the cooling, not applying or too much cooling paste (resulting in uneven heat dissipation) or somehow destroy the chip and simply return it to the store and ask for their money back.

    And? That applies to the cooler on a Celeron as well and has nothing to do with high TDP.

    The GPU is a lot larger

    No it's not. The GPU is firstly direct die and is smaller than a heatspreadder. On top of that the cooler is required to connect to multiple parts of the card. If you're worried about enthusiasts destroying any component while installing a heatsink, then the GPU is orders of magnitude more likely to be ruined.

    They also have the heatsink already assembled in most cases and removing it voids the warranty.

    You do realise that installing the heatsink on e.g. a modern 250W TDP TR4 chip or an LGA 3647 chip is no different than installing the fan on your old Pentium 3 right?

    Oh wait it is different. The modern chips have heat spreaders making it far less likely to damage the CPU while installing the cooler, and modern coolers have pretensioned retaining systems meaning you just throw on 4 bolts and call it a day. Then there's the advent of AIOs which makes the component sitting on your CPU significantly smaller and even easier to install than a heatsink. Seriously have you not built a computer in the last 10 years? The cooler on my Pentium 4 was significantly more difficult to install than the cooler on my current 180W TDP (rated, it actually draws closer to 230W overclocked) cooler.

    That may be surprisingly ineffective at actual cooling. The radiators in a house are designed to create natural draft and in order to do that you need a very high temperature differential between the water loop and the ambient air. That is what you get when you have a vertical fins running lengthwise through a radiator. Additionally most depend on convection and radiate poorly thanks to the default colour choice of off-white and the thick layer of lacquer covering the metal.

    Mind you it will still work. The amount of water in the loop needed to fill a large radiator like that can store a lot of thermal energy and thus it's unlikely a computer would move the temperature much over time. Even with poor thermal properties it may take an hour+ for the water temperature to do anything. However you may be better off pumping water through a large metal bucket. :-)

    That last "everything went batshit" reboot might have been caused by DRAM corruption.

    Interestingly not only did you just move the goalposts you made them as wide as the entire frigging field. I never said DRAM doesn't get corrupted, I said "filesystem". Your memory is chock full of data so in the incredibly remote chance that you actually suffer from an error that ECC detects you have an additionally incredibly remote chance that you happen to corrupt data in flight on the way to being written on the disk. The vast majority of these already incredibly rare events will as you say cause a "batshit reboot" or a crash, something of incredibly little significance to an average desktop user.

    Fortunately we can check how much value we get out of our ECC:

There are plenty of air coolers on the market rated in excess of 250W TDP which people put on a large variety of CPUs. Anyone who has ever done any overclocking is capable of cooling a 255W TDP chip.
