- Hi everyone,
I have a couple of questions from views through the comments in come of by videos and some have sent an email regarding about fan modes and how the rpms are controlled. I have done up this short video and hope this will clear all your doubts and questions.

KLEO I AM FIRST haha. I just woke up and watching this video while having breakfast. My husband was like Wow! He mentioned to me he had configured all motherboard fan sockets as dc. He thought all PC fans should be using dc and some special fans to pwm. Now we know what pwm is for. Thank you again for your detail explanation, we have learned something today.
Hi ya. Welcome back, hope you did enjoy your breakfast 😉 and you are most welcome. Knowledge is about sharing. The more we share the more we learn. Thanks Nox Mu 😊
Nice explanation, easy to understand thanks mate
Hi Kouhan, welcome to my channel and thank you for your feedback. All the best with your build too!😉
Everything you need to know. Great video!
Hi Vampirspiegelei, welcome back, thanks again for your feedback 😉
Bought a 5 pack of 3pin arctic p14s by mistake I plan on running them on dc mode like you showed many thanks man it’ll have to do till I get some other fans later down the line
Hello Herman A. Welcome back. Yup if for 3pin. Use dc mode and you are most welcome 😊
One point to mention is pwm fans can go at lower speeds. DC fans can be hit or miss, i.e., sometimes it will spin at a low rev and next time it might not spin at all.
Hello iDATUS, welcome to my channel. thank you for your feedback.
Thank you for making a clear video! I had MSI Z490 Tomahawk board that featured fine control of DC mode, from 0v all the way to 12v, and the only reason why I used my DeepCool CPU fan in DC mode instead of PWM was because of that fine control. Like it was mostly on 0 rpm while I was using my PC for standard web browsing etc. PWM was at around 20% and I found it unnecessary, just pulling dust while the CPU was under normal temps. Then I sold that mobo and bought this Asus H410M. Couldn't believe it forced DC mode to around 70%, was very dissapointed, and now, I'm looking into getting an ASRock Z490 ITX/TB3, but just have to find out how robust ASRock fan control is. If there is a way for the CPU fan to be in 0RPM while being in PWM, I'd gladly use it that way, but I can't find any info on web. If you have more data on this I would really appreciate it!
Hi Игор Кнежевић, welcome to my channel, as what I have experience with most motherboard these days, the DC mode is set either to 65 or 70 percent. so sorry that I do not know of any motherboard that does 0volts.
@@KleoYan thank you for answering! Thing is, my older Gigabyte B365m board also supported 0rpm DC which really confused me. I was thinking how could Asus forget such a big feature, even their higher end boards don't support it, well, they kind of do, as long as it isn't CPU fan. Just disappointed, and now in my hunt for a miniITX my choice is basically just ASRock Z490 ITX/TB3 and that's it.
@@igor4knezevic I see, thank you for sharing, greatly appreciated it and I do hope you find a board which have that function for you. All the very best buddy 😉
thanks very much
Hi Sofiane Tilleli, welcome to my channel and you are most welcome :) all the best in your build too.
thank you
Hi shalancomputer, welcome to my channel and thank you for your feedback 😉
I want to buy a h6 flow rgb, but the fans are 3 pin dc. I understand how to set ot to dc in bios. But would i still be able to set a fan speed curve in the bios in manual mode? Basically slowest at idle , the gradually increase voltage when the sysyem temperature increases ?? Or will a dc fan stay at the 1 speed (voltage) you set it to in bios , thank you , great channel easy to understand 👍
HI Craig DJ BULLER, welcome to my channel. You can only set to DC mode and depending on your board if it allows you to have a custom fan curve on your 3pin connector fans.
Mine only allows me to set at a fix voltage in DC mode ... example low temperature below 40°C to run fix at 7volts , mid temperature below 75°C to run at fix 9volts and at high temperature above 75°C to fun fix at 12volts
I plan on running 5 x Delta ~12-20w 120x38mm fans at around half speed or so, but with the option to control their speed. Normally I'd be looking at just hooking them up to a conventional fan controller with knobs to adjust voltage, which is the type of thing I've been doing for many years. But now it seems there are many of these Delta models that come in PWM form. Is it true that the PWM style will be significantly more power efficient and also generate less heat in the process of running at lower speed? Even if so, my problem is I don't see any fan controller products for PWM that provide direct physical control of fans via knobs or switches on the device itself. Instead, either they act as a molex/SATA powered PWM fan hub with a single control connection to a motherboard header, to control them all at once, or they are made to be controlled by proprietary software that only works once the OS is finished loading up its startup programs. I also doubt that any of these PWM hubs/controller devices can handle the power of 5 of these fans, and they usually don't specify the capacity. What I'd really like is a PWM controller with individual control knobs and a separate high power channel for each fan, but I see no such products like these.
Hi Max0r847, welcome to my channel are you talking about this 80mm and 60mm fans which are from Delta that have the ampere as 1.95a and 1.65a, those normally are plug directly to the old days PSU (Mustard cables) via the 4pin Molex. There are none in the market that has those kind of hub or controller, the ampere is too big. 1 of those fans if you are to plug directly to the motherboard, you will fry the board fan connectors in no time. I have no solution for you either, all the best in your build.
@@KleoYan Haha yea dude even my 1.2 amp Delta triblade 120x38mm will spike almost double that when it first starts. XDDD
Can I check so these 4 Pin are 12 voltage in general and 3 Pin are 5Volt ?
Hello sniperworks, welcome to my channel. Nope both 3Pin and 4Pin pwm are 12volts. The other connector if there are argb on the fan itself.. there is another 3pin connector and that's 5volts 3pin ARGB
*Pulse Width Modulation or Direct Current*
Hello Arround The House With Randy Meeks, welcome to my channel. it's preferable to use PWM 4 pin fans instead of 3pin PWM fans. but if you have a 3pin, you have no choice but to make sure of DC in UEFI.
Hey, nice video. I want to tell you I have 6 fans in case but one rear with pwm cause it is 4pin and the others have 4pins too but I take them to a Commander controller (corsair) and it is connected to USB port, the cpu cooler is AIO so the pump is connected to cpu_header but it has only 3 pin :/ So my question is, How can I change the fans speed to silently or as your video shows in "standard mode" ? Because when I open a game what is stressing a little the cpu maybe or the system, it going on loud not on full speed (I guess) but you can hear it from far... But anyway what I do not understand here exactly is my fans with 4pins connected to a controller-> controller to USB (with psu sata cable I think)-> and naturally the cpu_header with the pump with 3 pin.. Is there any option to change the speed?
Hi KrisiHD, I am not familiar with commander pro from corsair, as for pump it will be best to run at consistant speed since you are using your motherboard cpu_fan header, use the UFEI to control it or to use your motherboard application to control it. As for the rest of the fan speed that is under commander pro. you need to control via the commander pro application.
@@KleoYan Thanks for responding, yes I already got the software today and it is working fine, but when closed or restart the application not running it is the same, in bios settings I have some options like DC curves in Tuf motherboard, but I am afraid a bit because don't know how it work with the pump maybe more heat to processor or something just using that software 😁 or without program maybe the fan speed like in software default or called "balanced" 1500 rpm, i have 4000D airflow case so I can see it and hear it going faster and louder. Thanks your suggest!
hey my friend ! I know that these questions can be exhausting and I've done alot of research on this matter already and I'm pretty certain I have grasped what I'll do but I have 7 corsair fans 2 are 140mm sp140 elite and the others are sp120 elite and I have 5 motherboard fan headers I plan to hook each one to a header and then use 2 fan header splitters to obviously fit two fans on one header (I won't exceed more than 2 fans on one header as I know unless it's a high amp header I'd be in trouble) my question is this I have the rgb hub for 6 fans but I wanted to see if my 7th could be powered by the mobo (even if it's just to get the basic rainbow and not fully customizable) is that possible or will I have to go without one being lit. (I don't mind if that's the case because I defined know I'm not spending anymore money to have just 1 more fan lit)
Hi House Baelish, welcome to my channel, before you start daisy chaining, make sure you are clear of what each fans drawn. there are two section you need to take note. 1st the fan load 2nd the argb load, motherboard itself have fan and argb which does have limitation. as what I know most Asus boards have a fan load of only 1A. so do not daisy chain fans which will overload your motherboard fan headers. Same apply to ARGB. you wouldn't want to over load too.
As for hub, most of them comes with sata powered cables to the hub but you still need to know what type of load it has. if it's cater for 5 fans and 5 argbs, do not do more than 5 and try not to daisy chain over the 5 fans. else your hub will melt or caps/resistors will explode.
@@KleoYan thank you my friend yeah each header handles 1 amp and the fans draw 0.30amp so it can handle 2 fans per header as for rgb I'll be using the lightning node core and run usb 2.0 but my issue is the lighting node core only supports 6 fans and I have 7 so I can power my 7th fan but don't have a way to plug rgb in aside from plugging the 3 pin argb plug from the single fan into the mobo but I've heard this won't work idk =/ I don't want to buy a new hub
@@housebaelishgaming I see. if that's the case, yes, plus all 6 fans to your node and 1 to your motherboard. I would say the rear fan to your motherboard argb.
@@KleoYan thanks so much for finally answering this as no one has answered this for me before. Earned my sub brother that and your content is really awesome! I don't think my hub takes up a 3 pin argb slot to my knowledge I'll have to check
@@housebaelishgaming you are most welcome and thank you for the visit and to have sub my channel. All the best with your build. 👍
I have 4 fans 3-pin header , can i use a converter 3pin to 4pin to turn my fans from dc to pwm ?
Hi Geno7, welcome to my channel, am sorry to say, that it will not work as 3pin fan does not have the rpm wire.
Can you turn a non PWM fan on and off with python code? Based on CPU temp? I realize you can not control the speed (or maybe you can) but I have a lot of non PWN fans I don't want to throw away.
Hello CJ Lowe, welcome to my channel. The only thing I know as in to turn on and off is to use a physical controller SinLoon 4 Knob Cooling Fan Speed Controller PC 8 Channels Fan Hub for CPU Case HDD VGA PWM Fan PCI Bracket 12V Fan Control- 4Pin Interface Power Supply ( 4 Pin 4Knob ) a.co/d/932o5mb as for coding, I have no clue how to code.
Can 3 pin DC fans or 4pin pwm fans rpm be controlled in legacy bios?
Specifically in Gigabyte GA-G41M-COMBO Rev 2.0?
Hi AsifTML2, welcome to my channel, looking at the motherboard menu at page 37 (chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/viewer.html?pdfurl=https%3A%2F%2Fdownload1.gigabyte.com%2FFiles%2FManual%2Fmb_manual_ga-g41m-combo_e.pdf%3Fv%3D4072ad0a5376255ed4a29451488a555e&clen=10533932&chunk=true) I don't think is possible and the CPU Smart FAN Control which is meant for 4pin PWM fans. that's the only fan you can control and you will need to use the software call EasyTune. unless you purchase a fan controller bus bay. that will be possible
@@KleoYan Ya thats what I thought so. No point experimenting with ancient motherboard but thanks for reply...
@@AsifTML2 you are most welcome.
If they cant understand what you just said they probably shouldnt be playing with the bios in the first plase;)
Hi thx, welcome back and thanks for the feedback :D

Hi, I cant find the "fan configuration" in bios to change to DC from PWM ive been looking were you have yours but it is not there, I run an old Asrock Fatal1ty z170 ITX, dont know if the board has to do with the problem...
My case fans only have 3 pin, and I use Noctua NF-P14 fans in my case
hi Tor stein, welcome to my channel. As I do not have this motherboard, i am not able to view the bios intereface. but after looking at the manual download.asrock.com/Manual/Fatal1ty%20Z170%20Gaming-ITXac.pdf page 79. go to HWmonitor and scroll down. you should be able to do the settings, unless there are no sub menu to select between Auto, PWM and DC. this I can't help you with.
@@KleoYan Ty for trying, I guess there is no way to do this on my motherboard... it sucks but I think it is time to buy a new pc soon anyways haha. ty ty
@@touch. no problem and you are most welcome😉
so when to use each ?
Hi Mr. President, welcome back, if your fan connector is 3pin, I would use DC Mode, as for 4pin fan connector, I will use PWM Mode.
I would choose DC to save money from electric bill. Thank you for sharing brotha
Hello Francis Noms, welcome to my channel. Thank you for your feedback 😊
Which one do i use for my msi aio? Pwm or dc
Hi clouds, welcome to my channel. It depends on your fan connector. If your fans have 3pin use DC mode. If there are 4pin use PWM.

I have a PWM fan at "System Fan Speed Control" is normal and System Fan Control mode is on Auto. It gets hot when I play and runs at 700RPM. Can I put my fan speed on full and put my control mode on PWM?. It runs at 1470RPM and it's not hot anymore. Is it safe to run on full speed?
Hello Giurea Alexandru Eduard, welcome to my channel. Pardon me, is the System Fan Speed Control a physical device or is listed in your UEFI? Mind to let me know which motherboard you are using? In general, you fan can run as full speed with no issues. It will run till it’s lifecycle ends.
@@KleoYan hey!!! I have a gigabyte b450m ds3h, I changed my fan from DC to PWM but I haven't enabled the PWM yet! So my PC was overheating on normal speed and auto! So I can only set my fan on Normal (which is overheating when playing, silent which is worser or full speed which)
@@KleoYan my question is: Can I run the fan at full speed with PWM mode instead of normal and auto so my PC won't overheat? I have only one fan
@@alexrra be it pwm or dc mode. No issue, you can run at full speed.
@@alexrra btw your case is only with one fan? You should try to get a decent case and some decent case fans. One fan itself will not help to pull hot air out of the case.
That´s mean I can operate 4pin fans RPM with voltage ignoring 3 & 4 pins, I ask because I want to power one this 4pin fans with DC.
Hello Lobsang White, welcome to my channel and yes, so long you've set to DC mode you are using voltage to control the fan RPM which is consistent. but your motherboard is doing more work and your 4pin PWM fan might not last that long. due to the voltage resistance.
@@KleoYan thanks, may you help me with this... I want to operate this fan (PHANTEKS T30) with this PWM controller (VHM-802 12V PWM 4-Wire) on Aliexpress, it could work?
With the lack of potentiometer I suppouse the thermistor do the work in regards the temperature.
@@lobsangwhite the WHM-802 12V PWM 4-Wire, I would advise you to connect the red and black to a sata or molex outlet from the PSU, do not plug the red and black cable to your motherboard, it has it's own module. it should be fine if you do that. If you do not know how to crimp which + and - current to draw 12volts, I would advise you stop there and not proceed as back current will damage your PSU and if did it wrongly, it will damage your motherboard fan header too (if you intend to do that that is)
some info on how to draw 12volts form a 4pin molex from the PSU. i.stack.imgur.com/IA43b.jpg , again a disclaimer, I would be responsible if you damage your PSU or your PC components. PSU in modern days are all with black as compared in the past where PSU cables comes with mustard colors which is easily identify, please practice with safety precaution and do this at your own risk.
@@lobsangwhite oops pardon me, and as for your question, if you have done up properly with the VHM-802 12V PWM 4-Wire devices, yes your fan will react base on the temperature reading from it.
@@KleoYan I really appreciate for your answer, and to be clear I intend to feed the pwm controls with a 12V DC charger, this is not for a computer.
Bro im use aio cpu 3pin pump connector in 4pin connecter not in dc mode then now my pump fan is not working plz give a solution
Hi EVERY thing, which Liquid AIO are you using? I will need to know before I can try to help you out.
@@KleoYan darkflash symphony 240
@@EVERYthing-dx3tm hmm after looking at the specs of your liquid AIO. The fans are of own 4pin. It should work fine. Have you tired plugging to another fan header? If that still doesn’t work.

AIO pump always comes with 3 pin only?
Hello HARIHARAN T R, welcome to my channel, not all AIO pump comes with 3pin but nevertheless, for me, I am always using Arctic Liquid Freezer II and will only use either performance or full speed in DC mode only.
@@KleoYan Hi man, my EK aio manual says the following: "plug the 4-pin PWM connector of the pump into the motherboard"
so i set it to pwm in the bios right?
Nice Greetings from Poland!
@@zawiszaczarny1749 hi ya, welcome to my channel.. oo EK AIO nice.. you can do PWM settings no issues but I would advance to set it to run consistantly and not in fluctuate mode on the pump. I would set it to 70 or 80 or 90 fix. this will reduce your pump from fluctuating up and down, which will damage the pump in no time.
@@KleoYan :) thx been a sub for a good 6 months now, like your videos very informativ!
hehe yeah i got for a nice Summer deal on EK website in july..
yes i know that, will set it to 70 max 80 dont need more my cpu 13600k will be undervoltet anyways.

Is there such a thing as a 3-pin PWM fan?
Hello PomChatChat, welcome to my channel, nope I doubt so, fans with 3 pin connectors are not equipped with pwm. Therefore someone might have misinterpreted that, if you ever hear from anyone.
mygygbite bios has no response.. fan 4 pins p12 artic in a hub no response...
Hi andi bufi, welcome to my channel. If you plug direct, does it have response? if it does, means your hub have some issues.
