Hi, I'm wondering if the NZXT Noctis 450's PWM Fan Hub (it has eight 3-pin ports) could control my 8 PWM 4-pin fans (5 Corsair ML120 Red LEDs and 3 Corsair ML140 Red LEDs). Thanks.

I used to have 2 NF-A40 PWM's linked to the same header using a port, this port being the secondary CPU header (Which I didn't need). However, due to Christmas, I now have another 2 Noctuas, these Noctuas need a fan header, so I again linked them together using a splitter and plugged them into the port that the old, linked, corsair AF-140's were plugged into, however, I forgot that the Noctuas require more current. Subsequently, the two new Noctuas now no longer have enough current to run below 45% as they are using a case fan header. Is it normal for the CPU fan headers to deliver more current than case fan headers? If so, then is there anyway I can make the case fan headers deliver more current?

I'm buying some Corsair ML PRO fans, and looking though reviews they all say "it's important to note that they are pwm fans". So my question is, can I connect 5 of these fans to my Nzxt Sentry 3 and get full effect? Does the Sentry 3 have 5 pwm connectors? Thanks in advance :)))

So hello i recently bought PC componets and studied almost everything about building(and already built one before). But my concern is that in my new case there is PWM hub allowing up to 5 fans ... I already have 3 connected(case fans) and my question is if i can connect another 2 radiator fans and still it all can be all powered by CPU_FAN header on motherboard ad wont cause any damage to my MOBO. Case: Phanteks Enthoo Pro(front 200mm fan exchanged for 2x 140 mm fan (sp140) MOBO: MSi z170a gaming pro carbon PSU: evga supernova 750 g2

Hi guys! As far as I know, PWM and RGB "cables" are the same. I want to spice up my build with a bit of RGB action, and because I do not want to overload anything and for upgradeability I want to get a hub for PWM and my RGB headers. I currently use DEEPCOOL fans (normal, not argb) and I do not need a controller, just a hub. Now I was wondering if there is a difference between a PWM and RGB (12V) hub. And if you had a recommendation? Thanks in advance ^^

So I swapped in some Noctua industrial fans into a Supermicro case while back and I got the PWM 3000rpm model since the motherboard uses PWM through IPMI to control fan speed. The threshold is like 800rpm or something before a low fan speed warning comes on, theres three fan speed settings (Standard, Optimal, Full) and unless the mode is set to full the Noctua fans will not get above 600rpm. Do I need to buy 3pin fans instead?? Would they run at full speed then?

I recently bought 6 Lian Li Bora 120 RGB fans. The problem is that I am unable to control the fan speeds even though I have the PWM connector connected. All of the fans are connected to a Lian Li fan hub, which is connected by a molex connector to the PSU and a connector to a PWM header on the motherboard. Motherboard: Asus ROG Rampage V Extreme Fan: Lian Li Bora 120 RGB

So I recently ordered an NZXT H500i, and I am moving all my parts from my old case into it. However, I am having trouble. The case fan/RGB control hub has a PWM cable coming from it, which I assume would go into my mobo. However, I can't seem to find a single PWM connector spot on my mobo (MSI X370 Gaming Plus) or my PSU (Corsair CX450M). Any help is appreciated, I'm a bit frustrated rn.

As far as I can tell, in the ASUS x470 bios, under Qfan, there's no way to have 0rpm for PWM fans. What's up with that? I know in Gigabytes Z370 that was possible. I did it for all my fans, even the one's on the aio. The pc was almost dead quiet until a certain temp was reached. Any help would be appreciated.

Sup, so I want to make my PC quieter. I have some really cheap, loud $10 fans from Amazon right now. Since it's really hard to imagine the noise fans would make, how do you think I'd fair with 4 Be Quiet! Silent Wings 3 (Highspeed, PWM) fans? That'd run me about 80 bucks. The normal speed ones clock in about 16.8 decibels, but the high-speed ones are like 20. I assume I could cap the high-speed ones down to the normal speed and have the same sound. That would offer me more expandability too, so if it's hot, I could set the rpm higher. I'd have 2 intake on the front, one top, and one back - both exhaust. I'd be using these with a Wraith Prism RGB. I know, it gets loud, but I've noticed that's only when it's alone in cooling my pc. If I have my other fans running, it almost never flares up and makes too much noise. So 4 Silent Wings 3 with a Wraith Prism RGB... Do you think it would be nice and quiet? I plan on switching to a Dark Rock Pro 4 or a Cryorig R1 Universal (For the white color) CPU cooler if I want even quieter, but I want to keep my Prism's RGB, so I'd rather not. P.S. I saw a review saying that the frequency of the hum the Silent Wing fans make induces more rage than usual... Any truth to this? EDIT: I'm cooling a 2700x and have a 1080Ti by the way.

Hello, I'm almost done building my PC. I just need to install the GPU that I do at the end and the fans. I already have 3 out of 6 Corsair LL120 fans mounted to the case and those are connected to the Lighting Node CORE that was pre-installed in my Corsair iCUE 465X case. Each fan has an PWM cable, but I'm not sure were these should be plugged in. My mainboard is an Asus Rog Strix x570-e and I think I failed. I added a triple pack of Corsair LL120 to the build and didn't thought much about it. So I have 6 LL fans instead of 3 and I think I don't have enough headers. Is that right?

Hi! I'm searching for a really powerful 120mm fan but without pwm (with a molex connector for example), it doesn't seems to exist because it would be too loud, but if you know a reference or something like this, it would be really helpful. (I'm doing some experiments with a peltier module and a cpu cooler but because it isn't for a PC, I don't have access to a pwm control board.)

Before I start, here are the relevant parts to my issue: Gigabyte Z390 UD motherboard CoolerMaster ML240L RGB Liquid Cooler Fractal Design R6 Blackout Case Manual links: Cooler Master ML240L https://www.manualslib.com/manual/1452876/Cooler-Master-Masterliquid-Ml240l-Rgb.html?page=13#manual Fractal Design R6 Blackout Case (Attached) The wiring diagram from Cooler Master for this cooler is lackluster to say the least, it shows that the pump needs to be connected to the CPU_FAN header, while the actual fans need to use the supplied splitter and be connected to the CPU_AUX header (or equivalent), while all the RGB/PWM 4 pin headers all go to the supplied PWM controller from the ML240L box. I have two questions: 1. Does it matter if I connect the splitter fans to any SYS_FAN header on the board instead? The Gigabyte z390 UD only has one CPU_FAN header, and 3 SYS_FAN headers, and my case will have 5 fans total after the ML240L is installed with the 3 existing case fans. This creates a bit of an issue with header availability, I need 4 headers, but only have 3 for fan support. I could use splitters on the case fans to reduce the amount of headers used, but I don't want to wait for them to arrive from amazon, but I could just leave one unplugged in the meantime, and add it when the splitter arrives. 2. There is a PWM controller mounted inside the back panel of this case. The manual for the case instructs that the power for the controller is to be supplied via SATA cable (there was one nearby, so that was easy), and that the soldered connection from the controller be plugged into the CPU_FAN header. I have attached an image of the specific page in the R6 manual with the schematic for the PWM controller/fan hub. There is a total of 6 lead wires on the Cooler Master ML240L assembly, two from each fan, and two from the pump block. Here is what I want to do: Plug the fan hub connector into the CPU_FAN header, power the fan hub with sata (these are a given), then I want to plug all the Power connectors for the fans into the left side (3 pin) headers on the fan hub, as well as the block pump, and all the rgb/pwm 4 pin connectors into the right side, hopefully bypassing the need for the PWM controller that came with the cooler kit. OR I could use the PWM controller and use the fan hub simply for the fans, and the block pump (3 pin). Hopefully I explained my thoughts clearly enough. If anybody can confirm if what I'm thinking will work, or can help direct me otherwise it would be much appreciated. Thanks! d29f080e-6bef-44b5-a5fb-9e02b8767a29.pdf

Hello, I have a rosewill cullinan v500 case (3 fans in front 3 fans on top and 1 fan at the rear) and I also have a 360m radiator in front with 3 fans running on case fans (fans that can't be controlled by software or temperature in my pc) I would like to change the 3 fans in front in to PWM fans and would like to know where I'm going to put them on the motherboard? I want them to sync up with Q-fan I have a Hero XI motherboard so that when my cpu gets hot fans would spin on a higher rpm. I also have the top fans as exhaust and the rear one as exhaust. I would like to switch out all 7 fans with PWM 4 pin fans but I just dont know where to place them all Individually or using a splitter. Any help would be appreciated. Thank you in Advance!

Looking for high CFM, good RPM and excellent static pressure high-end 4 pin PWM controlled fans (not concerned with sound levels) for the somewhat "airflow deprived" Phantek Evolv X chassis. All help is appreciated

I am confused about the corsair icue software. I have 2 Corsair ML 120 Pro White Led fans and I can't figure out how to change the PWM for the fans inside of fans. The fans don't pop up in the software. Do I need one of Corsair's hubs to control PWM?

So I have 3x140mm Noctua ippc 2000 RPM fans rated at around 107cfm each on front intake, 3x Bora lite 120mm fans in top exhaust position rated at 54 CFM each. 1x 140mm rear exhaust fan rated at 82 CFM. I'm wondering with all this intake pressure (avg 275 CFM) from high end fans, should I swap in my two 140mm fans with higher CFM in top exhaust position? And uninstall the 120s? I was aiming for equalish pressure and even with aggressive fan profiles on the exhaust fans I'm not even within 100 CFM of my intake pressure. Seems rather unbalanced IMO. Additional Technical Data: Static pressure of above mentioned fans are: 4,00 each for the 140mm front intakes x 3 Around 1,06 each on the 120s x 3 And 1,86 on the rear exhaust fan. 1x Case is Phantek Evolv X I could alternatively swap in two higher CFM 140s in top position or crank up my 3 120s, or just replace my exhaust fans with all higher CFM variants. I like to keep my intake fans up pretty high for static pressure case restrictive reasons, that's why I'm concerned with having too much positive pressure in this scenario. Suggestions are appreciated Thanks as always

I would like to utilize a few of the fans (140mm Phantek SP) that came with my chassis. (Evolv X) But if you determine there's a conflict with VC/PWM I'll fit all PWM fans. I purchased three Noctua 2,000 RPM 140mm ippc fans for front intake which are the 4-pin PWM variety. The Phantek SP fans aren't terrible but they are 3-pin fans. They will be positioned for top exhaust. I'm utilizing a Deepcool FH10 (Ten-Port) PWM fan hub in this build. Can I hookup my PWM fans and voltage control fans to one Deepcool PWM fan hub and have speed control on the non PWM fans as well? Would it be wiser to utilize the case's fan hub (rather sub-par but has a few three pin connections) for the 3 pin fans, and use my Deepcool unit for solely the 4-Pin PWM fans? Motherboard is Asus X470 Hero VII. Thank you!

Hi guys! I have this motherboard https://www.asus.com/Motherboards/TUF-B450-PLUS-GAMING/HelpDesk_Download/ and I’m using 4 PWM fans, 3 from Corsair and one from Noctua. The mobo has 3 chassis fan headers a one AIO pump header which seems to be PWM as well. I decided to connect one of tha chassis fans in AIO pump header, it is working and allowing to adjust its speed as any other fan, but since I dis that, the boot is taking longer than usual, my guess is the mobo is trying to “talk” to the fan as an AIO PUMP but is not receiving all the info and hangs a bit during boot time. Am I risking damaging anything doing it like this? Would be better to get a splitter? Or there is any BIOS settings (which I may not be familiar with) that would prevent that delay or hang during boot? thanks

As the title says I want to get myself a new pair of fans.. actualy I want to get 6 to replace my old fans (they are broken and have no pwm control). Long story short: I want to get the 6 NXZT Aer RGB 2 fans. Problem: NZXT says But on the Pictures there are 6 fans and I aswell want to get 6 fans.. is this just a scam? Or do they mean 5 fans per channel (a total of 4*5 = 20 fans)? These will be 6 additional fans to my Kraken x72 (360mm) AiO liquid cooler witch comes with its own 3 fans.

I don't know if this is the right place to post, tell me if not. In order to create some airflow in a cabinet, I want to use a couple of old unused computer fans. They have 4 pin connectors, therefore PWM fans, and I want to use them connected to a phone charger via usb. The problem is: I modded a usb cable and connected the ground wire to the fan ground wire and the +5V to the corresponding fan wire. However, now the fan is ramping up and going to 0, then ramping up again instead of delivering a constant airflow. I believe it might have something to do with the other two wires that are not connected to anything. Is there anything I can do about it?

Hello, I have recently installed three HD120 Corsair fans, they run perfectly fine apart from the sound. When I was doing research people said I was able to control the speed of the fans etc so they will speed up when my pc goes under load/ has high temps and would slow down when at idle, as currently speaking I do not know what is the average sound to a computer at idle or under load. I was hoping speedfan would help however they are unable to find my fans - One is plugged straight into the motherboard (4pin) and then the other two are plugged into a splitter (also 4 pin) it is a three way splitter so should I also plug in the other corsair fan into it ? My specs are: 3700x stock cooler, rtx 2070 Super, 16gb 3200mhz, 750w psu and 3 corsair HD120 and two Corsair stock fans that come with the Corsair Spec-06 RGB white. I am one the having a quiet pc when at idle as I find it distracting and when I bought these fans all the reviews said that they sound perfectly normal and quiet at idle, but is this with a controller?? I have also installed HWMonitor and that does pick up my fans unlike Speedfan, however, I don't know how to use the program to its full advantage. I hope you can help me as I want my fans to be controlled by the temperature of the pc, so when at idle with low tempertutes it shouldn't need to be running at 100%. I have looked in the BIOS and hardware monitor, I have turned then onto Smartfan mode however I don't really know what I am doing apart from looking a graph - My motherboard is a x570 MSI Gaming Edge WiFi. Thanks in advance, I am sorry for poor grammar etc as I am typing this after looking for a solution for a couple of hours and I just want to start playing some games etc. I also don't know a thing when it comes to fans etc so sorry if I am being stupid- I am open for learning.

Hey guys, i've been having fun with my ITX build(my wallet hasn't, though), and while i'm mostly happy with everything(wraith max crappy rgb aside), there's something that's been plaguing my brain with doubt: DC and PWM fans, specially when using a fan hub. A while ago i changed my riotoro cr280 for a fractal design define nano S(great little case, if you cant get something smaller), i had bought 3 120mm id-cooling PWM fans, which were working relatively well(really noisy), but the nano s came with 2 140mm on front and a 120mm on the back, all from fractal design, so i switched to those. still i lost the ability to configure the curves, because the fans are DC. If i connect one of my PWM fans in the first port of the hub, i get to configure it, but i'm afraid that might cause problems for the other fans (maybe spin faster that they should? dunno). Now i'm thinking if i should get 2 120mm and 2 140mm phanteks PWM fans to replace my actual ones, but still the 120mm have a diferent max RPM than the 140mm ones. So i'm not sure, i feel i should have 2 hubs, one for 140mm and one for 120mm fans(which i cant because my mobo has 1 chasis fan header other than AIO pump and CPU). Also i'm kinda worried the hub will cause more problems than benefits(it's not sata powered, only connects to the fan header), maybe i should get a fan controller? if so, which one can you guys recommend? in case i didn't explain myself well enought(which i think i didnt) TL; DR;: i dont know if: 1. it's worth using a PWM fan over a DC fan. 2. the main fan on a fan hub can cause the other fans any problems(specially if they are DC and the main one is PWM, or if all are PWM, if the size/specifications are diferent) 3. what's the ideal situation for using more fans than the mobo has headers, is a fan hub good enough? should i get a fan controller? Thanks

Hey so i wanted to change my case fan control on my bios. I have a z390 aorus ultra motherboard so I went to smart fan 5 in my bios. I tested by trying to turn the fan to the lowest using the curve but nothing happened. I need some help thanks.

I have a Z370 Gaming M5 motherboard with an RGB header, that's a 4 pin. My RGB fans are addressable RGB fans so they terminate as 3 pins. They all plug into an RGB fan hub but obviously the hub also has one of those ARGB 3 pins, how do I hook this up? What do I need to buy to make them work? Thank you! Also, they're pwm fans if that helps.
