Will a 3-pin case fan from a 4-pin power supply work in a computer?

will be

and most likely it will be twisted to the full.

now 4 pin connectors are rarely equipped with voltage regulation

you don’t plug it into the connector without soldering to the desired connector, secondly it’s not a fact, it’s better not to invent such things from the bulldozer. it's not just that different

Will be.

50/50 probability that the speed control will not work - it depends on the board.

4th wire - PWM, speed control signal. If the mother supports voltage regulation, any fans will be regulated.

If not, then only 4-pin fans, and 3-pin will always work at 100% speed.

Yes. But, if the motherboard does not know how to regulate speed by voltage - it will yell at maximum
