Check out paragraph 81 of the indictment. One of his co-conspirators was having a discussion with a lawyer; the lawyer said staying in office past January 20 would trigger “riots in every major city in the United States, and the co-conspirator replied, “Well, [lawyer], that’s why there’s an Insurrection Act”.

Are you using leaded or lead-free solder? If it’s lead-free, it has to be hotter and you may also find extra flux helps.
If you want to tinker with the printer a lot, sure. If you want something that reliably Just Works, you’ll probably need to increase your budget. I’ve heard consistent stories from friends that their various Ender 3’s required lots of tinkering or upgrades to make them happy (one who found it so frustrating he gave up twice before finally getting it working ok, and this was with help from our “expert” friend who had lots of experience with Ender 3’s). And consistent stories from friends that their Prusa MK3’s Just Work and they don’t understand what the Ender 3 friends are talking about for how to solve various problems, because they just didn’t happen.
My personal suspicion (owning neither) is that the QA on the Enders is probably not great, so some of them work pretty well and others are miserable. Any given user has no way to tell whether they are doing something wrong, or just got a machine with really poor tolerances. Ender 3’s are really common on support forums like this one, but I’m not sure how much comes from the low price leading to high sales volumes vs. users on average having more trouble getting jankier machines working well. But Ender clearly has many fans so…?
Are you asking about adding a fan, or moving one of your fans from non-PWM to PWM?
It’s because of the “lift to drag ratio”. Airplanes in level flight at ordinary speeds generate about 15x as much lift as drag meaning if the engine spends 1 unit of work moving the plan forward, the wings give 15 units of work* upwards. So flying level needs about 1/15th the engine power of going straight up. (I’m using “work” very sloppily here, not in a precise physics sense.)
You can see this in sailboats too, which can travel faster than the wind when they’re sailing at an angle to the wind. Efficient boats travel faster when they’re going almost perpendicular to the wind, not straight downwind! This is because the “lift” of the sail pulling the boat forward even more strongly than the push of the wind in the downwind direction.
While I can’t give an intuitive explanation for why this is, there’s a very easy demonstration that it’s true: kites. If a kite had a lift-to-drag ratio of 1, then it would fly at 45° up. It would fly 50 meters downwind of you when it’s 50 meters up. But any decent kite can fly at a much steeper angle than that; sometimes they look like they’re right over your head! That’s because with a lift to drag ratio of e.g. 10, the 1 unit of drag gives 10 units of lift; if it’s 10 meters downwind it will be 100 meters high.
