Hello mates. Can i split my two 140mm fan from a 280mm rad into a single CPU PWM port on my Board? The pump is connected directly to to the psu via 4pin molex to 4pin pwm. My concern is if I split the CPU 4pin Pwm on my board to connect my two 140mm fan, will those two fan achieve optimum performance??? In terms of "will it hit the fans max or highest RPM" if I set to 100% stuff like that.. -
So, I just built my brand new system which features a ryzen 1700. I have seen all over the intrenet that people also experience random 10-ish degrees spike at idle. Now the prooblem with that is it keep making fans ramp up. I've searching for a while now and I can't find a way to change the fan speed update period in the UEFI of the crosshair VI Hero, so I was hoping someone on the internet did. -
My motherboard only has 1 sysfan header, so I'm forced to use a fan hub, since I want to add 2 or more fans (no controller, I have no front bays and dont want to use dials, want to control from bios). And I want to be able to control them all from the bios, which I would ideally do, by controlling the hub, attached to the pwn header. If I got a pwm fan hub, could I hook my 3pin fans to it and they would be regulated by the hub? I'm just trying to find a solution and save a couple bucks, also it seems weird to me that most fans that are bought on amazon or in general are non-pwm, while many people must use them with a hub or controller.

Hey there I have a little question about the Cooler Master Liquid Cooler 240M. The Manual does not say if i have to controll the Pump with a PWM or not. Can you guys help me out there? Thank you!

just got a Silverstone fan hub 1 to 8 (PWM). i was wondering what i use to control the fans? Also after installing the fan hub i plugged it into the cpu fan port and turned on my pc and got a cpu fan error. but all the fans are working side note i had to boot from the bios.

I'm Looking to do a build in the 'Dark Base Pro 900 Case' with an Asus ROG Maximus X Hero z370 Motherboard, but I'm confused on how the case fans will be controlled. The case has a PWM fan hub, does this mean that all fans connected to this hub will spin at the same speed as each other and all react to temps the same? Or do I get to control individual fans? e.g. a few fans only start when the system gets to a certain temp while other fans are reacting to CPU temps? Or does this fan hub get controlled by the BIOs and does this give me control over individual fans? Thanks in advance

The fans can be the most expensive part of a water cooling loop when you need 5 and PWM fans I would like good fans not just random fans that aren't a name brand but I would rather not play 15 dollars per fan.

Hi everybody, Quick question: is it possible to manually control (via software in Windows) the speed of case fans (PWM) that are connected with PWM directly to the motherboard 4-pin sockets? I'm looking for a way to best balance noise/performance. Thanks in advance!

TL;DR! My post was WAAAY too long, so here's a TL;DR version. Feel free to read the original full post after this one. What is it? It's a project to create the ultimate über fan controller. However i want to add so many features that i may call it case controller. Now, i have a PCB designed, and i'll make a first batch. Main features : control of 6 PWM channels for fans, led strips, or whatever uses 12V and can be PWM controlled, 256 levels between fully off and fully on; high power for each channel, at least 30W max per channel (i'm very conservative); 6 plugs for temperature probes, normal or waterproof, this number can be increased a lot (hundreds) and easily; 5x analog inputs for potentiometers, analog sensors or whatever; 5x digital input (buttons, digital sensors) or outputs (leds, 5v leds strips, adressable LEDs...); shared with analog inputs, so it's 5 total; 3x I2C plugs, for sensors (gazillons of I2C sensors are available) or output devices (text LCDs, OLED LCDs, sound devices, etc); extensible up to 127 devices on the bus; real time clock for whatever use we can have for that; controlled by an Arduino Nano (2$ board), so can be programmed/upgraded via USB (soon to be with ESP32 chip, adding more power, wifi, bluetooth); draws power from a molex or whatever source providing 12V and 5V; can control individually adressable LED strips, with RGB (meaning whatever color for whatever LED of the strip independently from the other LEDs); open source, open hardware, so extensible; monitoring each fan speed; can print things on LCDs; can send data to PC; can receive data from PC; can work with or without the PC. State of the project Now i have a PCB designed, i'll soon order a first batch. I have all components in my stash. This is the first prototype : Most of the features mentioned here have already been tested, i have yet to test a board implementing all of those at the same time. I want to make a device with the community, without any consideration for commercial stuff or whatever, the idea is to make a cool device, with other people, have people modifying it, adding their code, etc ... The board is 50*70mm (2*3 inches approximately) and has 4 mounting holes. i'll make a 3D printable box to put it in a PC case, and a 5"1/4 tray for it later (in an optical bay, with an LCD in the front? what do you think guys?). By the way, it can also control watercooling stuff, the probes can be waterproof or not (no difference in code just a slight cost increase per probe for the waterproof version) and we can add flow sensors in the watercooling loop, or PWM control the pump or whatever you want. The whole board is relatively cheap to produce (should be 20-30€ for a complete unit), simple to assemble, and that's the first version i have. it will improve over time. However, i'd like to hear from you guys what should be included on such a device, what killer feature have you not seen on other fan controller/case controllers? what sensors would you have in your PC, smart desk , server cab or whatever? what would you want to control automatically? And don't hesitate to throw crazy ideas, many can in fact be implemented easily... Next post is a detailed version of this post, with technical details about many things, you don't have to read it, it's there for those who want to investigate further. Don't hesitate to ask me anything about this project.

I'm just looking for some help finding the best 200mm fans out there. My plan is to use a 200mm as an intake for a Cooler Master HAF XB EVO and exhaust out the front and back of the case (I plan on having radiators there for a custom loop). My main problem is just that there doesn't seem to be an awful lot of options for 200mm, especially if you're looking for pwm. I know Noctua has one but I'd like to know what other good options there are.

Hello all! I recently installed a corsair h75 AIO water cooler and the two fans it came with. Only one issue, my Asus motherboard BIOS wants to protect me from myself (a bit late for that) and limits the duty cycle to 40% minimum for all the chassis fan headers. I think my CPU fan header might have a lower manual duty cycle of around 20% but I'd rather not screw with that because i'd prefer to keep my CPU fan to auto adjusts speed based on core temps. Anyway, preface out of the way, the thing I wanted to ask you lovely ladies and gentlemen of the LTT forum is: What can I do to limit the rpm of my fans... Silly question I know, but besides forking out ~$50 for a PWM fan controller, maybe there are some other things that could be done? I'm not adverse to installing some ghetto resistor in line to the fans considering I have already voided the warranty on just about everything in my case (the aforementioned h75 was for my GPU after all...). But I'm pretty sure the old "voltage divider" resistor trick doesn't work with PWM fans anyways... So, got any ideas? I'd rather not spend money tbh as it's a bit hard to come by right now. And yes, before anyone comments that this thread has already been made a million times, I'm doing it because I know how much you all LOVE answering questions that have already been asked before

I'm having trouble controlling fans either through BIOS or Speedfan. Bios won't ramp them up enough when controlled by PWM and Speedfan is ramping them up way too much down low and PC suddenly becomes a wind turbine with any form of temp above idle. I have a Fractal S36 AIO as an intake with it's three PWM fans run through on it's inbuilt header to the CPU header. Than three more EK Vardar PWM fans as exhausts daisy chained to a single header. What I want ideally is to be able to ramp the CPU / intake fans when the GPUs get over a certain temp as well as normally ramp up for CPU temp like it already does. I also want the exhaust fans to be controlled by taking temps from both GPU1 and CPU and ramp up as temps increase if either get hot enough. At the moment I can barely OC my GPUs as they thermal throttle without the chassis fans spinning up as well. GPU fans I control through MSI Afterburner and they ramp up and down as wanted Build: https://au.pcpartpicker.com/list/BCYKVY

So I'm RGBing up my go to pc and had fans on my mind. I have an H110i GT AIO water cooler in ANGLE and was thinking about replacing the fans with RGB ones. I decided I really like how the HD140s look and would like to use them. But the h110i uses a 3pin power connector to power the fans. HD140's are 4pin pwm fans. Will this cause a problem? Will I still be able to control the leds? Is there a better choice for 140mm SP RGB fans? Also one thing to note the only thing about this particular build you could call a theme is it had a decent amount of corsair parts in it.

Hi, I have an idea of how this will work but i wanted to run it by a few people who might have done something like this before. In short, I'm building a system using an ASUS Z270I (itx) motherboard, the board has the following available fan headers(and pin outputs): CPU Fan - PWM (ground, +12 V, rpm, PWM Signall) CHASSIS FAN - (ground, +12 V, rpm, +5V) AIO PUMP - (ground, +12 V, rpm, +5 V) I have two radiator fans (120 mm pwm), 3 chassis fans (2x80 mm, 1 x 140 mm) and the pump. My original plan was to run the 2 radiator fans off the cpu fan header, the pump off the AIO header (note it has a 12 V power feed direct from the PSU also) and the 3 remaining fans off the chassis fan header. However, i did not realise that the AIO header did not support PWM, thus, if i use this header for the pump i will only ever have a fixed pump speed 42% of maximum, that doesn't seem all idle but also not the end of the world? But... I also know that this board can likely control fans via dc voltage on the none PWM headers, so my thinking was what if i connected the pump PWM signal pin to the +12V pin instead perhaps I could have DC control of the pump speed via the AIO header instead? After all, PWM is just a digital way to mimic a voltage so i doubt the pumps going to notice the difference between a 7V PWM signal and a 7V DC signal? Here's the link to the pump i'm using https://www.ekwb.com/shop/ek-ddc-3-2-pwm-laing-ddc-3-2-pwm Thanks, Christian -
I want to use a Fractal S36 watercooler and I want to have a near silent build but I want to have a lot of overclocking headroom and I am going to eventually use the G1/4 threads that it has for a custom watercooler. But I want to slowly ramp up the fan speeds one by one to minimize noise and I need to know how many PWM headers on the MSI X370 Gaming Plus. Thanks!

So I have a question involving my upgrade to a new case. I have got a pack of 3 Thermaltake Riings (140mm) with the included controller and also got an Arctic Liquid Freezer 360 to house in my not yet arrived Fractal Design Define S (windowed) . I planed to do a push-pull setup in the front and mount the 3 Riings in the top to exhaust, but today I have noticed that the Riings need a pwm signal to light up. So I have to connect both the Riings and the 6 fans from the aio to my single cpu/pwm fan header to make full use of them. But if i use a splitter for pwm this would not work properly because the fans got different max rpms (Riing: 400-1000 or 800-1500 and Aio fans: up to 1350). I really want to use the leds in the Riings but i don`t know how to realize all of that with only one pwm header. Or would it work ? please leave suggestions and ideas how to do this Thank you

Hi, I'm about to fill my loop right NOW! I forgot that this new pump came with only a PWM header, so I can't use the jump start PSU method to fill the loop with the molex, because this time it has no molex. I have filled up the res, any good suggestions before I proceed? -
I'm in a club at my school where we are going to be making an autonomous vehicle and they want me to to figure out the pros and cons of using a raspberry pi for it. They also want me to figure out these: Real Time Capability PRV PWM Versatility Usability I'd appreciate if anyone can help me out and give me some information on the subject.

Perhaps I'm just overthinking, but this is truly the most frustrating part of designing my own PC. I'll put 4x Noctua NF-S12A fans into my case. I've got two problems with this. First, I'm not sure which version to go with, the PWM (4-pin PWM) or the FLX (3-pins). As far as I can understand, a PWM fan's speed can be controlled through UEFI or some application, and can adjust itself to the temperatures, while the 3 pin one can't be. Is it correct? I've just ordered an ASUS Z170 Pro motherboard, which looks like this: http://www.tweaktown.com/image.php?image=imagescdn.tweaktown.com/content/7/5/7592_06_asus-z170-pro-intel-motherboard-review_full.jpg The issue is, that I have no idea how many 4 and 3 pin thingies my motherboard has, plus some of them say CPU, or extension, or whatever. I'm completely lost here. I'm pretty sure that one socket is reserved for the CPU cooler fan. The specs of the motherboard: https://www.asus.com/Motherboards/Z170-PRO/specifications/ These are the connectors on the Z170 pro: 1 x CPU Fan connector(s) (1 x 4 -pin)1 x CPU OPT Fan connector(s) (1 x 4 -pin)2 x Chassis Fan connector(s) (4 x 4 -pin) ----------------> 2 x 4 x 4 ?! What?! 1 x 5-pin EXT_FAN(Extension Fan) connector How can I use these things? The 5-pin one is the one where anything can go? Which NF-S12A version should I choose, if I want to fit four of these noctuas onto the Z170 Pro, and make them adjust their speed automatically? The articles on the web quite often contradict each other, and they require deeper knowledge than I have. So they're a bit useless. Thanks for any help. Matt

Hi, I have a motherboard that has: My cooling setup will be a Hydro Series H115i 280mm Extreme Performance Liquid CPU-Cooler with both of its default fans replaced with ML140 Pro LED Red 140mm Premium Magnetic Levitation Fans (4-pin). Additionally, I will have another ML140 Pro LED Red 140mm Premium Magnetic Levitation Fan (4-pin) at the back of my case to act as the exhaust. At the front of my case, I'll have 3 ML120 Pro LED Red 120mm Premium Magnetic Levitation Fans (4-pin) as my intake. Finally, at the top, I'll also have 2 ML120 Pro LED Red 120mm Premium Magnetic Levitation Fans (4-pin) as another exhaust. In total: 1x Hydro Series H115i 280mm Extreme Performance Liquid CPU-Cooler 2x ML140 Pro LED Red 140mm Premium Magnetic Levitation Fans (4-pin) 1x ML140 Pro LED Red 140mm Premium Magnetic Levitation Fan (4-pin) 5x ML120 Pro LED Red 120mm Premium Magnetic Levitation Fans (4-pin) I've already checked that this setup would work with my case. Knowing my motherboard specifications, what do I need to make my setup work (obviously my motherboard alone doesn't have the necessary inputs)? I would like to have control of all of the fans from software in my computer, if possible. My case does indeed have a fan hub (but they're all 3-pin!). My case only has 2.5" and 3.5" drive bays, by the way. Thanks.

I'm buying new fans (Corsair ML and NZXT Aer RGB (yes, I have a hue+)) that have 4pin PWM connectors but I wanna use a fan controller. However, I can't find any fan controllers with 4 or more channels that support 4pin connectors and was wondering how it will effect the fans if I just use 4pin-to-3pin adapter and use a fan controller with only 3pins. Will the fans still work or will I just lose some ability to control them?

Sup folks, I'm shopping for some good 140mm intake fans for my Phanteks Enthoo Evolv ITX and came across the Noctua NF-A14 PWM and the Noctua NF-A14 FLX. What's the difference? They look identical, cost exactly the same and are both 140mm. Can someone please explain to me what the differences are - if there even are any - and which one I should buy? Thanks in advance, Regards, TJ (possible useful information: Motherboard: Gigabyte GA-Z170N-WIFI CPU: Intel Core i7 6700k 16GB of RAM (Ballistix Sport LT, 2x 8GB) Nvidia GTX1070 Founders Edition PSU: Rmx 550 1TB WD Blue HDD 256GB SSD (Samsung 750 EVO) Corsair H110i AIO)

I cannot decide which one of these to get. I want a low noise and versatile fan for multiple spots in my case. Im planning to put one on my current CPU heatsink and later one in the rear exhaust. The main thing for me is the noise fan makes. Does anybody have experience in both of these and could give me an opinion in a real world situation. I've heard that IPPC fan has a bit higher pitched voice in the same RPM than the regular A14, but is this true? Make some sense to me and tell me what to buy. Price difference here in Finland is that the IPPC one is 5 euros more expensive and in the case that if it is better, is it still worth 5 euros more? Thank you for anything you can input in this case!

So i have this case but removed the fan hub because... well it was ugly. My motherboard won't run the case fans below 60%. I want to set a custom fan curve with the fans way below 60%. Will this be possible if i put the fan hub back on and connect the case fans to it? the fans are all 3pin fans. i'm trying to get my machine to be a bit quieter... especially considering my cpu isn't even topping 35 degrees. My case is the Phanteks evolv entoo tempered glass edition. Motherboard is an asus ROG x99, it's my first build so I am not an expert...yet. Sorry if I am posting this in the wrong place, but i just created this account and don't know the rules here yet. I also just built my first pc and am having this question. any response will be appreciated.

My mobo has three chassis fan headers. Only number 1 is 4 pin PWM, the other two are only 3 pin. I've noticed that though the other two work fine, when I use a 3 pin non-pwm fan on that chassis fan 1 4-pin header, I have zero control over the fan whatsoever. It runs at full speed. No matter what I tell it to do in the BIOS, any fan I plug into that port just runs at 100%. Do I just have a busted header or what?
