yes you can. its called dc control or volt control

no. the fourth pin is used to control the speed of the fan. Without it the fan will always run at full speed.

Have you tried turning it off and on again? Maybe Restart it?

he doesn't know what he's talking about.... you absolutely can. most motherboards even default to DC control rather than PWM unless they detect something on the sense pin.

in bios you can manually force it to use one or the other if the motherboard doesn't detect correctly the type.

3-pin can be plugged into 4-pin header. 

I've been using computers since around 1978, started learning programming in 1980 on Apple IIs, started learning about hardware in 1990, ran a BBS from 1990-95, built my first Windows PC around 2000, taught myself malware removal starting in 2005 (also learned on Bleeping Computer), learned web dev starting in 2017, and I think I can fill a thimble with all that knowledge. 😉 I'm not an expert, which is why I keep investigating the answers that others give to try and improve my knowledge, so feel free to double-check the advice I give.

you wanna know why controllers and MB manufactures let you control the speed with les than 4 pins? 

2pin Fans: a controller/MB software can be set to a curve based on volt to control the Fan, with 2 pins you dont know how fast its spinning but this is not needed to control it

3pin Fans: a controller/MB software can be set to a curve based on volt to control the Fan while the fan reports back to the controller/MB what speed its spinning

4pin Fans: The Controller/MB gets another option to control the Fan by pushing 12v all the time but telling the device how often it should use the 12v(PWM), while the Fan is reporting back. 

 

Fan splitters 4pin: only 1 fan reports back what the speed of the fan is. but all of them gets the signal (PWM) on the 4th pin)

If I remember correctly, a PWM Fan can be plugged into a 3-pin header, but then it's just like a 3-pin fan.

 

 Is pulse wave modulation a fancy way of saying frequency modulation but specifying it's through pulsing?

 

Daisy chaining is just another form of splitting, right?

not so sure about that. PWM is the control where 12v to the device turns off and on fast (or not so fast for low speed or full speed)

frequency modulation is non specific. it could be done on both analogue or digital systems for different tasks. FM radio is famously Frequency Modulation.
but PWM as a control technique is a digital technique that does not modulate the frequency, so it's not FM. it's not used to store the data signal, it is just a control signal. it tells the thing at the other end of the wire to turn on and off in sync with it. it's just flicking the light switch really fast. and the thing that is modulated to change in PWM is the length of time the signal stays on vs off. as a percentage, because you can't be more turned on than all the time (i've tried...)

it's used in digital light diming (when the carrying frequency is too low it bothers many people because they can feel the flicker) it's used in speed control systems and it's used in controlling the heat elements on your cooktop and ovens. it can also be used in charging circuits and many other palces.

LOL!

 

Thanks for the research and explanation!
