Good vid! thanx for the info. I was going to buy a 3pin fan for my hyper 103 to match the other fans in my case but i think i will just stick with what i have for now.
@@CircuitsAnonymous You didn't help anyone, because your experiment was bogus. It amazes me how so many people blindly accept anything people claim online these days. There is no scientific basis for what you are claiming.
I just wanted to to cheer you up a bit. I was installing one of those cpu water coolers 120x240mm with dual fans and while hunting around for info, I happened on your site, thanks by the way. In the end I put one fan connector to the cpu fan 4 pin header and the other fan to the chassis 4 pin header. In the bios cpu fan showed around 1200rpm and the chassis fan showed a bit over 1000 rpm. I'm considering a Y-connecter, so both fans will be driven as a pair by the single cpu fan controller. How about that?
Wow, your channel has some good quality for so low subs. I just have one question , if I have a 3 pin fan can I connect it to a 4 pin header in my motherboard ? with no problem? Keep the good work !
yes, you can connect 3-pin fans to 4-pin headers, they'll just run in straight up DC mode. Also i guess I got low subs cuz Im still new? Thanks for the support!

This is actually incorrect. 3 pin fans can also be driven with pwm dc. So that makes your whole point mute. The reason some fans can throttle better is due to driving them with voltage or pulses. Voltage is not linear whereas pulses are very linear. I.e you can drop volts to 5 volts and fan won't even move but it will still be using power. But if you send it full 12v but only pulse it for a very short time. The fan wil move very slowly and use very small power.. the Only difference between 3 and 4 pins. Is that 4 pins have there own mosfet. So you only need to send a tiny pulse and clean dc. 3 pin fans used in pwm mode will need chunky switched dc and may have issues with switching Rf noise in conductors.
Great video! But what can you do when it seems the mobo is letting temps get too high and you want a different fan profile. Remember that heat causes aging. It is better to run at cooler temps. I sadly bought an ASUS mobo (WS-C422) and it does not have any internal access for fan control. Also, any recommendations on a good monitoring software for temps and fan RPMs. Thank you!
Random question, I am looking to buy the MSI B450 Mortar motherboard and I want RGB fans to go with it. I know it has 4 Pin fan headers on the motherboard but I am not sure if I can just plug the fans into those headers and be done with it or if I will need some other kind of set up to control the lights. Please help, its giving me a headache lol
i need help i just bought new fans , my new fans are 4 pin females . my old fans are 3 pin males.. is there a way to hook my new fans . an adaptor i cant find anything to help me i dont know what to do
Video is old but, speaking of silent system. I have 3 fans (3 pin), and u know they can run at 500-600 rpm in DC mode but can't run below 1000 in PWM mode. I can stop them in DC mode when my PC temp is below 43 (C) degrees but can't do it in PWM mode. So for fans with only 3 PIN DC mode can provide u more than PWM. Correct me if i'm wrong.
well bro, I have ant esports 510 air cabinet where 4 pre installed fans is connected and it has 4 pin header which is connected to a controller but they are argb fans but how can argb fans have 4 pins? the have 3 pins
If I have a 3 pin cable and a 4 pin on mother board does it matter if the 3 pins go from right to left and leave one empty or left to right and leave one empty or it just doesn't matter
Many cases come with 3 pin fans and very often also a fan controller included. One connection goes tot the PWM fan header on your Motherboard. Then you connect all your 3 pin fans to this fan controller and they can be used in a PWM configuration. But I noticed in many cases that does not work very good. What I always do is swap the included fan controller for a full PWM fan controller., with 4 pins headers. This only when your Motherboard has not enough PWM fan headers. I always install PWM fans in my case, for extreme air cooling and also for radiators and what not. I'm a big fan of air cooling, then I trie to put as much fans possible inside the case. Via the added fan controller I can control each fan to its max potential ans usage. Intake, outtake etc. Thanks for this good video by the way.
Hey I’m ver new to pc and I’m trying to connect my 3 pin fans to my 4 pin will it for sure work because it looks like it doesn’t fit in the right slots of the little holes in the the 3pin
After 4 years of using 3 pin fans on 4 pin configuration my X99-a mobo is starting to short. I have to clear cmos for it to start any of the fans because of this one troublesome fan prong.

Could always then plug it into a manual fan controller if the 100% rpm is just too much... decisions decisions. (not getting new mobo)

After 15 years on practicing with voltages on numerous rigs i decided to throw from the last floor all 4pin fans and voltmod them to 5V. Sometimes i think my rig isn't powered on
There should be no difference between 3 and 4 pin. Both have a RPM sensor that goes back to regulate either the PWM pulse or DC voltage level. The reason you let the system calibrate the 3 pin is so it can measure the RPM speed at the highest voltage (12v) to then calculate how much voltage to apply to the 3 pin voltage pin to apply a certain RPM speed. The 4 pin does not require calibration this as it simply uses PWM pulses of varying length from 0% to 100% width to control the speed as per usual. Sending pulses on and off or varying the fixed voltage to the fan works in the same way to control speed. Again there should be no difference in using 3 or 4 pin, 4 pin is just a better way of doing it over the old 3 pin style because it does not require calibration.
Wait so what i know is that 3 pin fans are manually controlled, meaning that if i want it faster i have to manually increase the voltage (between 5-12v), and pwm are automatically controlled by the motherboard. Are you saying that even with 3 pin fans the motherboard can control them but not as accurate ? in both 3 and 4 pins i can set a fan curve ? Thanks !
There is more of a degree of control with PWM fans, yes. Most motherboards however take care of the calculations for voltage, versus you doing it manually.
3 Pin-fans are usually equipped with a thermistor to sense heat buildup and with that system control the speed of the fan (in usually a pretty crude manner with not that much room for slower speeds, is my experience). You can leave out the (usually yellow, if the plus and minus are red and black) third wire and the fan will spin up just fine, but at it's top speed, the third wire serves as a thermocouple for the computer, to let you know how "hot" it is there, for instance.
@@Dutch3DMaster so if my 4 pin pwm splitter has 4/3 pin and i want to setup second fan on cooler in cpu header one fan always works about temps and second with 3 pin on full speed no metter what temp ?
@@Sauluzaz It might not work that way, because the yellow wire of both fans will give a readout that way and possibly confuse the computer (the yellow wire also gives some information about RPM based on temperature readings of the fan itself, which is meant for (basically) a self regulating fan). A 3-pin fan splitter I got with my Noctua cooler has one fan running full speed (red and black connected only) and one fan with the yellow wire. Using a non-PWM fan and one that is capable of being used with PWM might give inconsistent results, since I do not know how the PWM wire works, if it is merely used for some kind of feedback on the PWM setting used by the computer or what is needed for the fan (and thus, it adjusts it's speed by using the red and black wires and using a PWM signal on that) you might see one of the fans slowing down up to the point it's uncapable of keeping itself moving when temperatures are low, or (more annoying :P) when this happens, the coils in the fan that make the magnets want to move away out of the magnetic field start to wine because the frequency is either to high or to low, or the circuitry was not designed for frequencies that high (PWM control can go up into the KhZ range easily). Long story short, you could try it, but keep an eye on readings (or on the fans itself, to be sure) and see what happens.
Thanks for the video. Did you use a program to control the 3-pin fan speed, or do they run at full RPM? I am asking this since PWM control is no longer available for 3-pin
@@Uraim If you can see RPM depends on the compatibility of the motherboard with the fanl and 3 pin are controlled by voltage, so check your mobo to see if the headers can be changed to voltage mode.
@@tinn9843 wow thx i saved 20EURO because 4pin cpu tower cooler isn't so cheap (3pin tower cooler with blue led cost is 16Euro and 4pin tower cooler is 30+EURO :D
how to 2pin to 4pin? it bugged me out how I got a new 120mm fan (the two pin one) to replace my current same-size 4pin fan..... only to fond out I opened the case and a wire was preventing it from spinning. I hope none of you have to go through this.
I search the speed adjustment of the fan and the results is some motherboard suppor 3 pin fan speed adjustment, I am getting the Rog b 350f ganming, can this motherboard adjust the fan speed? My case fan is corsair 12v DC 0.30A brushless fan, is pre installed in the case 2 140mm fans in the front and one 120mm in the back.Hope someone could reply me asap cuz I am getting rest of the components and start the build at black Friday.
I just saw your video and I was curious because my 3 pin fan i added to my set up i used as an exhaust seems like it’s barely spinning or just not as fast as my other 4 pin fans
As long as the Tacens Aura fan is a static pressure fan you should be good. If its an airflow fan, you will get less performance than with the coolermaster fan. But if your only doing casual pc stuff, its probably ok.
Id say the fan blades are different enough to skew these results. The LED versions copy the blades of the typical standard cheap case fan , while the pwm has a slightly wider blade as it reaches the outer edge of the chassis, also thiere blades are the same as the higher end fans . Both do share the same chassis. No one attempted this test but you, but I do recommend redoing this experiment with the enermax TB silence fans. They literally sell the same fan with the same rpm with 2 different connector types. Noctua may do the same with their redux series but i recall a rpm difference
Hi,I was under the impression that the 3 pin fans are not controlled by the motherboard and just spin at their max speed while the 4 pin fans are controlled by the motherboard.
3 pin fans are dc controlled so they're regulated by voltage, so the motherboard can control how fast the fan spins by how much voltage it decides to send to the fan header.
Yes. If your motherboard didn't detect your fan as PWM connection (3-pins), it will use voltage to control your fan speed. If your motherboard detect your fan has PWM (4-pins), it will use "digital" signal to control your fan speed. The pro of using PWM is the fan speed is more accurate because your motherboard just telling the fan speed it want and then the fan internally control the speed for it. The non-PWM fan is not so efficient because all manufacturer's fans have different speed even you set them as same voltage. So it is not ideal for motherboard to control the speed accurately.
@@CircuitsAnonymous So basically what it means is if it's 3 pinned and is controlled by voltage, the mobo controls the fan speed by checking how much voltage is being used?(More voltage=more power=more heat=faster fan speed?) And the 4 pin has pwm signal which directly checks the temperatured and is therefor more precise?.
I have a question. I want to buy a 'Dex DX-2011', which is a Cooler Master Hyper T4 knock off [maybe I could even get the original], but I want to change the original fan [which is 4 pin] for one with a rgb led ring, which is 3 pin, only for the a e s t h e t i c s. My CPU is an AMD A10 7860k, not overclocked. Would that be a stupid idea? Thanks!
Its not a bad idea, so long as you can find a static pressure fan. Static pressure fans perform much better, than normal air flow fans, for CPU cooling.
A fan splitter cable: amzn.to/2xx2xIq, or a fan hub: amzn.to/2fuVStV would be your best options. I believe one header can drive up to 4 -5 fans, so you should be able to make it work!

I have (3) 3 pins fan. I wanna use fan splitter since that my motherboard only have (2) 4 pins. Will the fans work when I use the fan splitters. Btw, I know that 3 pins will work on 4 pins, just wanna know is it still works when I connect the 3 pins to the 4 pins splitter thingy
IZZGAMER123 unfortunately, my fan splitters haven’t arrived yet. So, I’m still waiting
Did it work?
Hendo yes, it does. My fan splitters failed to arrive to my house, and I did it. It works
Very deserving of more subs
Thanks a lot!
Can I just wire a 4 pin fan up as a 2 pin and ignore the other ones?
I have a bitfenix case with a rbg controller and my b450m steel legend not picking up the 3 pin header u know y? It's so frustrating I cant control my ram I hate polychrome
Plz link a 4 pin to 3 pin. I need to connect a 4 pin fan to a 3 pin 60 p channel monster .
Plz help I cant find the dam connectors they allaays have 3 needles In the 4 pin 8(((
Does it matter if I plug a 3 pin into 4 pin?
Is 3 pin fan good for cpu fan? I just bought ID cooling dk 03 cpu fan. It has only 3 pin while my mobo msi b75a g43 has 4 pin cpu fan socket
After 15 years on practicing with voltages on numerous rigs i decided to throw from the last floor all 4pin fans and voltmod them to 5V. Sometimes i think my rig isn't powered on
Voltmodding you say, I'm going to have to look into that.
I bought a 3 pin fan for my cpu heat sink is that a bad thing?
Really helpfull video! Thanks a lot
Good video dude
There should be no difference between 3 and 4 pin. Both have a RPM sensor that goes back to regulate either the PWM pulse or DC voltage level. The reason you let the system calibrate the 3 pin is so it can measure the RPM speed at the highest voltage (12v) to then calculate how much voltage to apply to the 3 pin voltage pin to apply a certain RPM speed. The 4 pin does not require calibration this as it simply uses PWM pulses of varying length from 0% to 100% width to control the speed as per usual. Sending pulses on and off or varying the fixed voltage to the fan works in the same way to control speed. Again there should be no difference in using 3 or 4 pin, 4 pin is just a better way of doing it over the old 3 pin style because it does not require calibration.
musclesdude Exactly.
Thanks for the informative video :)
Can in put a 3 pin to a 4 pin conector?
Wait so what i know is that 3 pin fans are manually controlled, meaning that if i want it faster i have to manually increase the voltage (between 5-12v), and pwm are automatically controlled by the motherboard. Are you saying that even with 3 pin fans the motherboard can control them but not as accurate ? in both 3 and 4 pins i can set a fan curve ? Thanks !
There is more of a degree of control with PWM fans, yes. Most motherboards however take care of the calculations for voltage, versus you doing it manually.
If I have a 3-pin fan (cooler) and the motherboard has only 4 pins, how can I connect it?
*What's the Difference Between 3-Pin and 4-Pin Fans?*
I remember a time when electric motors required only 2-Pin (+/-) ....
3 Pin-fans are usually equipped with a thermistor to sense heat buildup and with that system control the speed of the fan (in usually a pretty crude manner with not that much room for slower speeds, is my experience).
You can leave out the (usually yellow, if the plus and minus are red and black) third wire and the fan will spin up just fine, but at it's top speed, the third wire serves as a thermocouple for the computer, to let you know how "hot" it is there, for instance.
@@Dutch3DMaster so if my 4 pin pwm splitter has 4/3 pin and i want to setup second fan on cooler in cpu header one fan always works about temps and second with 3 pin on full speed no metter what temp ?
@@Sauluzaz It might not work that way, because the yellow wire of both fans will give a readout that way and possibly confuse the computer (the yellow wire also gives some information about RPM based on temperature readings of the fan itself, which is meant for (basically) a self regulating fan).
A 3-pin fan splitter I got with my Noctua cooler has one fan running full speed (red and black connected only) and one fan with the yellow wire.
Using a non-PWM fan and one that is capable of being used with PWM might give inconsistent results, since I do not know how the PWM wire works, if it is merely used for some kind of feedback on the PWM setting used by the computer or what is needed for the fan (and thus, it adjusts it's speed by using the red and black wires and using a PWM signal on that) you might see one of the fans slowing down up to the point it's uncapable of keeping itself moving when temperatures are low, or (more annoying :P) when this happens, the coils in the fan that make the magnets want to move away out of the magnetic field start to wine because the frequency is either to high or to low, or the circuitry was not designed for frequencies that high (PWM control can go up into the KhZ range easily).
Long story short, you could try it, but keep an eye on readings (or on the fans itself, to be sure) and see what happens.
Thanks for the video. Did you use a program to control the 3-pin fan speed, or do they run at full RPM? I am asking this since PWM control is no longer available for 3-pin
My motherboard was able to to tune the DC voltage for the fan, its not as precise as PWM, but it does the job.
I see thx
can you put a 3 pin cable in a 4 pin conector??? pls help
and now can i connect my tower cpu cooler have 3pins but my Motherboard have 4pin? :D and does its showing the cooloer spining speed? :D
Yes, just make sure to connect correctly your 3 pins cooler.
@@tinn9843 :D
@@tinn9843 but so does the speed measurement in bios? does i see the cpu cooler speed in RPM? and does controlable the fan? :D
@@Uraim If you can see RPM depends on the compatibility of the motherboard with the fanl and 3 pin are controlled by voltage, so check your mobo to see if the headers can be changed to voltage mode.
@@tinn9843 wow thx i saved 20EURO because 4pin cpu tower cooler isn't so cheap (3pin tower cooler with blue led cost is 16Euro and 4pin tower cooler is 30+EURO :D
how to 2pin to 4pin?
it bugged me out how I got a new 120mm fan (the two pin one) to replace my current same-size 4pin fan..... only to fond out I opened the case and a wire was preventing it from spinning. I hope none of you have to go through this.
Good video Really helpful
Very well said. Thanks!
What do i need to hook up my fan controller its 4 pin female molex? But psu has no male with pins to go inside
I search the speed adjustment of the fan and the results is some motherboard suppor 3 pin fan speed adjustment, I am getting the Rog b 350f ganming, can this motherboard adjust the fan speed? My case fan is corsair 12v DC 0.30A brushless fan, is pre installed in the case 2 140mm fans in the front and one 120mm in the back.Hope someone could reply me asap cuz I am getting rest of the components and start the build at black Friday.
I just saw your video and I was curious because my 3 pin fan i added to my set up i used as an exhaust seems like it’s barely spinning or just not as fast as my other 4 pin fans
I dunno my other fans have more blades as well so I thought it was cause this one was a 3 pin connector
Great video brother I'm going with the 4 pin😋
The cpu cooler is 3 pin my motherboard have 4 pin , will it support? pllzzzzzzzzzzzzzzz help bro
So ive changed an old cooler master (4 pin) to a tacens aura ii (3 pin) for cpu cooling . Any Problem? Its just a casual pc, not for gaming.
As long as the Tacens Aura fan is a static pressure fan you should be good. If its an airflow fan, you will get less performance than with the coolermaster fan. But if your only doing casual pc stuff, its probably ok.
Id say the fan blades are different enough to skew these results. The LED versions copy the blades of the typical standard cheap case fan , while the pwm has a slightly wider blade as it reaches the outer edge of the chassis, also thiere blades are the same as the higher end fans . Both do share the same chassis. No one attempted this test but you, but I do recommend redoing this experiment with the enermax TB silence fans. They literally sell the same fan with the same rpm with 2 different connector types. Noctua may do the same with their redux series but i recall a rpm difference
That's a good idea, thanks for your input.
Good video , btw what is the name of the game you are playing at 2:45 - 2:50
Final fantasy XIV, its pretty good if your into MMORPGs.
Good video thanks for the help
Hi,I was under the impression that the 3 pin fans are not controlled by the motherboard and just spin at their max speed while the 4 pin fans are controlled by the motherboard.
3 pin fans are dc controlled so they're regulated by voltage, so the motherboard can control how fast the fan spins by how much voltage it decides to send to the fan header.
so 3 pin fans can be speed-varied? Ithought they ALWAYS spin at maximum rpm....
Yes. If your motherboard didn't detect your fan as PWM connection (3-pins), it will use voltage to control your fan speed. If your motherboard detect your fan has PWM (4-pins), it will use "digital" signal to control your fan speed. The pro of using PWM is the fan speed is more accurate because your motherboard just telling the fan speed it want and then the fan internally control the speed for it. The non-PWM fan is not so efficient because all manufacturer's fans have different speed even you set them as same voltage. So it is not ideal for motherboard to control the speed accurately.
@@CircuitsAnonymous So basically what it means is if it's 3 pinned and is controlled by voltage, the mobo controls the fan speed by checking how much voltage is being used?(More voltage=more power=more heat=faster fan speed?)
And the 4 pin has pwm signal which directly checks the temperatured and is therefor more precise?.
Thanks, now I know :)
Hi,
Question: How can you run a PWM fan with two pins only (like a regular fan)?
Thanks!
I have a question. I want to buy a 'Dex DX-2011', which is a Cooler Master Hyper T4 knock off [maybe I could even get the original], but I want to change the original fan [which is 4 pin] for one with a rgb led ring, which is 3 pin, only for the a e s t h e t i c s. My CPU is an AMD A10 7860k, not overclocked. Would that be a stupid idea? Thanks!
Its not a bad idea, so long as you can find a static pressure fan. Static pressure fans perform much better, than normal air flow fans, for CPU cooling.
Thank you! I didn't know about that. More research to do...
Do all motherboards have 3 and 4pin slots?
If my AB350M Pro4 Micro ATX motherboard only has two headers, what's the best way to add an additional case fan?
A fan splitter cable: amzn.to/2xx2xIq, or a fan hub: amzn.to/2fuVStV would be your best options. I believe one header can drive up to 4 -5 fans, so you should be able to make it work!
Great video - ty
