Long story short… bought a server off Craigslist. Whatever, 700$, 2x Xeons, 384g of ram. Something. Quite a score right? well the thing is loud. I get it, passive heatsinks. Duh, it’s a server Let’s watercool the CPUs! Done. Now it’s confused. Pump is DC/molex - straight full power, yet at 37c all 10 fans go super fast then idle and back again There aren’t any fan curve options in the BIOS let alone a Cpu header, I just see fan0-6. Tore apart the manual too, watchdog and stuffs TLDR; got a server, fans are always super loud. So STFU, watercool it. Now it’s 100% to 20% and back to 100. Annoying. help? (Yellow duck as a life raft) ~ughh

Firstly can someone explain how Pressure Sharing technology works? Second, does it need me to buy a PWM 3 way splitter for 3 Fans?

I have 4 very powerful fans (64W draw at max power, and yes they are loud). I do have a solution for PWM control using a Raspberry Pi Pico and a few potentiometers. That solution is a bit clunky, and I will have to run the pot wires outside of my case via PCIe covers. I thought of a different idea though: take the PWM & RPM pins from the fans to the corresponding pins directly on the mobo (or maybe a PWM hub), would that work? Note: The fan is powered from a 4 pin molex connector soldered directly to the fan wires. It works, but I am not sure if a mobo has some safety for the PWM to not work when the 12v isn't connecting. Note 2: I know that the GND needs to also be connected to the mobo, I have a way to do that. -
Good morning/evening, I am not looking for a fan splitter, but the exact opposite, a header splitter! My MOBO has a cpu fan header, and my GPU has a fan header. Ideally, I'm looking for a solution that would read both headers and pass along the higher PWM signal to a single fan. Why? In the photo I uploaded of my case, I want that bottom 140mm to be driven by the CPU and GPU headers. Yeah I could just connect the bottom 140mm to the GPU, but I'm air cooling a 5950x so I really want it to stay linked to the CPU. I'm not sure if a simple splitter would work for something like this, because youd ultimately be feeding two PWM signals down the same wire, backfeed, etc but IDK! If there is not an off the shelf solution, I think a raspberry pi PICO can read PWM and drive a PWM signal? not sure, I do already have a raspberry pi in my case driving that screen lol.

Hi, I’m currently dealing with an issue where I do not have enough 4 pin fan connectors for all my rgb fans. I have looked at getting a splitter cable, however I’m not sure if PWM splitter cables work with RGB fans? Can someone please help me or clarify this issue? Any help is deeply appreciated.

is there any difference between molex fans and pwm fans, knowing that molex fan runs at full speed everytime? would there be any issues when using a molex fan despite that it is really loud?

Hello everyone, first of all, English is not my mother tongue so i hope you understand what i say. I went to BIOS to check for any Fan settings for my CPU, i checked every section except the last one which was "PC Health Status", i went there and saw the setting "CPU Smart FAN Mode", this setting was set to "Auto" i clicked on it to see for any other options and i saw "Voltage" and "PWM". I did a quick Google search about this setting and people say that "PWM" is better than "Auto", so i did what they said, i changed the setting from "Auto" to "PWM", my question here is, what does it actually do? I mean what are the advantages of using "PWM" than "Auto"? Is it better? Because i'm a bit confused here. Also my CPU Fan is a 4-pin and my motherboard has a 4-pin for the CPU Fan so everything is good with the headers. Thank you Specs: • Motherboard - Gigabyte GA-P55M-UD2 • CPU - Intel Core I5-750 2.80ghz (OC'ed to 3.1GHz) • Graphics Card - Gigabyte GTX 1050 TI Windforce 4GB (Not OC'ed) • RAM - Corsair 12GB DDR3 1333mhz • SSD - Samsung SSD 860 EVO 500GB -
Hi guys, I'm planning to build a pc with 10 ARGB fans(Deepcool CF120) and 1 Cpu cooler(Coolermaster MA620M). Firstly, I need a hub to connect all the ARGB and PWM connectors together, but there aren't much ARGB and PWM Hub with 10 or more connectors of argb and pwm each on it. Secondly, How does a Hub actually works? Some says the sata or something, is sata coming from the power supply or the motherboard, and after i connect the sata from somewhere to the hub, i have heard that i need to connect another cable from the hub to the motherboard, how does it really works???? So i'm getting a ARGB and PWM hub, but not much manufacturers have 10 argb and pwm connectors hub, can someone suggest one to help me? How does a hub works? where does it connect from(motherboard or psu) and where does it connect to(motherboard which connector or pin or something)? FYI, i'm getting Asus TUF GAMING X570-PLUS (WI-FI) and Lian Li O11D case. Wish to hear your reply soon, thanks!

Hey, Got my PC here and the case fans are so loud, they are just the stock 3x 140mm fans in the define S2, but I just really think that they shouldn't be this loud. All 3 fans are plugged in to the included fan hub but I don't think it's working. Tried adjusting the fan curve but it doesn't pick up that there are any fan's connected to the system, changed the fans to the PWM header on the hub and if anything, its louder. Does anyone else have the same problem? or are these fans just geniunly loud?

Confession: I like a bit of RGB Now that is out of the way, I am looking for a new case (have a Cooler Master K380 with two BeQuiet Silent Wings 3 PWM fans installed). I really like the look of the Corsair iCUE 220T RGB with the Tempered Glass front window (not the best for airflow, but aesthetic are important to me), problem is that it comes with three SP120 RGB PRO fans which are 3 pins meaning no PWM. Since I do want my PC do be quiet even under some load (Games that is), PWM fans is a must for me. What are similar sleek looking cases (with a tempered glass front) that either have 4 pin fans from factory or come without fans so I can install whatever I want? Would it other wise be worth it to buy a (used) Corsair iCUE 220T, remove the stock fans, and install LL120 RGB or HD120 RGD from Corsair? This would make it a lot more expensive, but would also be what I am kinda looking for. Any reply is appreciated!

I have the COLORFUL X370 motherboard. My case fan is pretty old and connected to a 3 pin port on the motherboard labeled sysfan Now i am trying to replace it, as i fear the fan's bearing is failing. However, markets only have PWM fans, with 4pin connectors available. Do i need to find a really old fan model which has 3 pins connector, to replace my current fan? Or is there some work around I can use? Please guide -
Good day, Sorry if this has already been answered somewhere on here but I searched and couldn't find anything. I have a variety of Noctua fans in my PC. I've just found out that plugging in 5V PWM fans into regular PWM mobo headers could damage the fans but I have had two NF-A20 PWM 5V fans plugged into PWM motherboard for some months now, controlling them with ASUS AI Suite and they seem to work fine. I understand that standard fan headers are 12V. I understand that PWM fans vary voltage to control the RPM. I understand that ASUS AI Suite (that came with my RoG X470-F mobo) 'senses' what the fans can do and operates them appropriately. In my mobo manual, all these headers are said to be 1A, 12W. Can anyone please advise me if I am causing any lasting damage to my motherboard or is it just the fans? What will happen if I don't disconnect them? Thank you

Hi so i have a set of deepcool fans Rf120s so 3 of them vibrate alot and its been screwed on tight to the frame. any ideas

Morning, I've just some new fans and a PWM controller from amazon, my fans were old that's all and wanted some new ones. The fans and PWM controller: https://www.amazon.co.uk/gp/product/B07JD22QF5/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 https://www.amazon.co.uk/gp/product/B07GJGF56L/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 Now do run the 4 pin in to the 3 pin of the fans and daisy chain them? If so is it easier to run straight to the MOBO with one 4 pin rather than the controller or should I run each fan to the controller individually? Gurky

Hi all, some days ago I got a leftover RGB strip from a friend of mine, and since then my life has changed. An idea torments me: I like the way they look (hooked them up to a molex) but I would like them to be useful rather then beautiful. I've done a TON of research, but it looks like what I'm trying to accomplish is too specific to be found. My chrome's bookmark list lately consists in just this topic (send help): My plan is to have the LED strip cut in half (two strips, each having 3 LEDs) and have one strip controlled by CPU temp, and the other one by GPU temp: if the temperature is cool the LED will glow blue, if it's hot it will glow red. One thing to know: I know very little about electronics, if anything at all. Sorry in advance for my ignorance LEDs specs: one strip of 6 RGB LEDs @5V (1,44W, 0,288A) Without further talking, here's my two ideas: 1) The quick and simpler one: T1 and T3 transistors are NPN, T2 and T4 are PNP Basically, if the PWM signal is "low", T2 and T4 will output a high current to the LEDs, therefore making them glow blue (PWM low = fans not spinning, or spinning slow = low temperature) while T1 and T3 will output a small current, if any; if the PWM is "high", the contrary happens. Violet will appear at some point (red + blue = violet), but it's ok 2) The arduino way, which is pretty self-explanatory: it will be connected via a virtual serial port, and it will read CPU and GPU temps using some software such as SpeedFan or so. These programs will be logging temps, and I'll need to write another program to send those values to the arduino. I'll need to write a script for the arduino too, so that it knows what to do with those values. This is the best option because it reads the real temperatures, but being this a small project I think it would be a little bit overkill (maybe I'll do it in the future) I'm ready to buy resistors and transistors, but I would like to know what components I should choose, or even if this is possible to do. If I (more like "us", or to be more correct "you", hypothetical helper) manage to make it work, I will be glad to make a video step by step so that other people don't run in the RGB hell, which is only red. Because I use the 5V molex right now. And it's on red. Thanks in advance PS: I know it's off-topic, but I've read some topics here and...no wars ? No poisonous comments ? You've built up a nice community, it's nice to be here !

So I´ve just "finished" my first build from the ground up and everything is working as it should as far as posting and detecting the components go (haven´t installed windows yet). But there´s one question i have: : So I´ve plugged my Ryzen stock cpu cooler fan into the CPU_FAN header on the motherboard and then i connected the PWM fan hub to the CHA_FAN header. Now... the chassi fans are spinning but i don´t get a report on their rpm or the number of them in the UEFI. Why is that? I think they´re also running at max speed in the UEFI. (The CHA_FAN header has a pin that is called "CHA FAN PWM" shouldn´t that mean that it supports fan control with the hub?) A side question: What is a normal RPM for a cpu cooler fan and a chassi fan in idle? ( Ryzen R7 1700 at about 40 degrees) Thank you so much for the help in advance!

Hello, I got myself a new case today which included 3 fans by itself. I'm not really sure what to use but I read that I could control the fan speed when I use the PWM connectors. So I hooked 1 fan using the PWM connector and the other 2 fans connected to the first one using Molex (MolexCeption?). I placed the PWM on my mobo on case fan 2 and when I go into the bios it shows up, but when I lower the speed level it doesn't work. After I tried to put it on case fan 1 on the mobo but same result. I was looking for a Zalman Fan Mate 2 but im not sure if I can plug 3 case fan's on that splitter Anyone knows something else I can try?

Can I replicate 100% pwm by putting 5v into the pwm fan header? I am using an ekwb pwm pump and would like to get it to 100% without turning the computer on as I am leak testing the loop. The pump doesn't have a high enough pressure on its own and I don't have a Manual fan controller. Thanks

Hey, I am searching for the name of (PWM, in the pic they are not, but i search for this type of headers) Fan Headers. There are several tubs(? is that how it's called in eng?), but they are not that important for me (prefered the ones in my photo, because ez). I want to buy 3-4 pairs of male-female headers for my little LED project, I'm into now. Would be great, if anyone could give me the name of them. Cheers

Hey team, I need some expertise for a new build. I'm going to be using a Kraken X52 front mounted in the Corsair 460X RGB. I'm planning to use the existing SP120 RGB fans in Push for radiator cooling, just as many of the Youtube builds seem to be doing. What I haven't been able to see though is how they connected all the fans correctly. I'm not planning any crazy overclocking, but would still like variable fan control, if possible using the NZXT CAM software. Problem is, I understand these fans are incompatible without something like a Grid+. Let's assume that this set up is non negotiable, so my questions are: What's the best way to configure this, and what extras will I need to buy? Have you completed a similar build, and how did you connect it all? Useful thoughts appreciated Edit: Part list for clarity https://pcpartpicker.com/user/Apemanz/saved/#view=vC8sYJ

Hello all, My machine is built inside a converted Powermac G5, and inside I have 3 Arctic PWM fans. My motherboard only has 1 3pin fan connector for chassis fans, so I am daisy chaining the fans off each other. My motherboard is the Asus M5A78L-M/USB3 How would I get a hardware devices that I can plug the fans into, and then manipulate through software. Are there any? Thanks, Josh

I am running 15 system fans in my new rig, however all the fans I plug into my fan controller https://www.amazon.com/SilverStone-System-Cables-Black-CPF04/dp/B00VNW556I/ref=sr_1_1?ie=UTF8&qid=1489195954&sr=8-1&keywords=3+pin+fan+hub spin at full speed no matter what. Motherboard input makes no difference, I tried several different ports all are the same. Is there anything else I can do or is there a better fan hub I can buy?

Hi I need some help identifying this fan header and whether is supports PWM fans. It's the CHA_FAN1 highlighted in red in the picture. The 4th pin doesn't say PWM like the CPU_FAN its says +5V. Any help would be great!

Hi, my PWM fans in my build aren't working. Here's my fan setup: I have a 8-port fan hub that supports PWM. One port is 4-pin and the other seven are 3-pin. The fan hub is connected to my motherboard's CPU cooler header using a 4-pin connector. My CPU cooler is connected to the one 4-pin header on the fan hub. All other fans are connected to the 3-pin headers. I cannot control fan speed for some reason. Stuck at ~1450RPM unless I overclock my processor in which they automatically increase, but I can't manually change it.
-
So I am looking for some fan controller recommendations. Not worried about price but I need to to be intelligent. I am after some thing that will monitor the temp sensors and adjust fan speed automatically, options for alarms, custom fan curves an a hardware display would be awesome but not required. So far all the solutions i can find just give back a temp allowing you to manually adjust fans not so much a "smart controller". I am after 4-5 temp sensors, if it is powered by software on the system that is fine as well Thanking you in advance for your time, Akin
