Hey guys, I can't seem to find anything that's applicable to my case so... I recently bought a new fan to replace the stock one on my Cryorig H7 (TT Riing 120mm) The problem is, it's incredibly loud on stock speeds. And, it's not PWM. Normally that wouldn't be an issue, as I could just adjust the voltage, but... My mobo is a Gigabyte B85M-DS3H-A It's a cheapy $50 mobo, but for a modest budget build it works fine. However, the UEFI is absolute crap, and doesn't have a way to adjust voltage on the CPU header. I've tried SpeedFan as well, but with no luck. Is there any way I can control the speed of this fan? It's so loud I can hear it through my headphones, and it's driving me insane...

I have an AsRock Z97 anniversary motherboard with 2 120mm non-pwm case fans connected to it. For the last year i have had them on silent and they were spinning fairly slowly as expected. recently the spin at full speed even though i haven't changed anything. I have done a viruse scan, system file check, flashed my bios, and tried different fan headers all of which yield no solution. I know i can just manually set fan curves but im wondering if anyone knows why this is happening.

Hi guys, I'm planning on making an HTPC build on one of Intel's new Kaby Lake non-K CPUs and I have updated my planned build as according to the responses from my previous post. Updated Parts List: * CPU - Intel i7 7700 * Mobo - Asus Z270i ROG Strix Gaming * CPU Cooler - Noctua L9i * Memory - G.Skill Trident Z 16GB 3200MHz * SSD - Samsung 960 EVO 250GB NVMe SSD * HDD - (2x) WD Black 2.5" 7200RPM * GPU - Asus GTX1070 Founder's Edition * PSU - Corsair SF600 SFX Considering the overall black and silver/grey theme of the build, I would like to ask if I could replace the Noctua L9i's included (pardon my language) shit colored fan, the NF-A9x14 PWM: http://noctua.at/en/products/fan/nf-a9x14-pwm.html Fan Specs: * 92x92x14 * Max RPM - 2200 * dB/A - 19.9 * m³/h - 50.5 * mm H20 - 1.64 * 4-pin PWM with the plain grey colored Noctua NF-B9 Redux 1600 PWM: http://noctua.at/en/products/product-line-redux/nf-b9-redux-1600-pwm Fan Specs: * 92x92x25 * Max RPM - 1600 * dB/A - 17.6 * m³/h - 64.3 * mm H2O - 1.61 * 4-pin PWM And if possible, I would also like to ask which fan would most likely perform better when it comes to cooling my CPU since I don't know how to translate the Redux's higher airflow (CFM) and lower max RPMs as compared to NF-A9x14's into actual cooling performance. I'm leaning towards using the Redux fan as an alternative purely for aesthetic reasons, but I would still like to know the difference between the fans Thanks in advance, and best regards.

Hello all, Can anyone recommend any good 4 pin controllable fans (PWM) Im looking to setup some custom fan curves in my computer so it doesn't sound like im siting next to a Super Hornet all the time (always capped at 100% even though idle temps are low.) Thanks in advance guys!

I am building my first pc and am trying to put some more case fans because the excess heat the evga 1080 ti ftw 3 is going to be putting into my case. this is my parts list: https://pcpartpicker.com/list/KPZHKZ I am planning on putting 1 more fan in the front bottom of my case, and 1 more fan in the top back of my case. I found some mixed information online about whether or not the NF-A15 will work as a case fan or if it is specific to a cpu heat sync. Please help clarify if I can use these fans in my case and if you see any other issues.

Hey everyone, I need new case fans for my Rosewill Thor V2 as the bearings are going bad. I was looking at corsairs af140mm but I'm only finding static pressure and I wanted to hook them up to the built in fan speed controller. Would I still be able to change the speed with them connected even though they're static pressure or would I need pwm fans?

So I've had my custom loop up and running for around a week. And it's only now that I have noticed the PWM Pump (https://www.ekwb.com/shop/ek-xres-140-revo-d5-pwm-incl-sl-pump) is constantly producing a fair amount of noise - like a hard drive running at high speed. The pump is connected to a separate MB fan header so it can be controlled separately from the fans. However, no matter what speed settings I set the pump to run at in the BIOS it will always runs at 4800rpm. I would like to get full control of the pumps running speeds which considering it's a PWM pump it should be possible. I've tried checking around the internet for solutions but I haven't come across a solid answer, any help will be very appreciated... Help me LTT community, you're my only hope!

so the thermal take ring 14 rbg non premium used pwm 4 pin into a controller, but apparently u cant set it just use pwm from the mobo to adjust speed to thermals? what were they thinking with this having to open ur sidepanel to change the fan speed depending on wether ur gaming or browsing the web? i guess i personally would then set them to 1000rpm hope they are quiet and prob not open the case to change fan speed ever again and only the rgb

Hey all, I recently got a new set of case fans (ALL PWM AND ALL PLUGGED IN TO CHA_FAN HEADERS). The issue I'm having is that I can't control the speed of the fans from within Windows 10, I've tried ASUS AI Suite 3 and SpeedFan and neither of them have worked. This is what happens: 1. Go into the BIOS and turn on chassis Q-Fan Control, the fans stay nice and quiet while sitting in the bios. 2. Save the changes and exit, the computer starts the boot/POST etc... the fans get slightly louder. 3. By the time Windows is booted the fans are sitting at 2000RPM, and my computer suddenly sounds like a jet taking off... I got really pissed off at it (At the time I thought it was my CPU cooler, so I unplugged the case fans, Started the system and realised very suddenly that it was my case fans being loud the entire time. I don't know how to solve this, all my fans are 4-pin PWM fans, plugged into the chassis fan headers on my ASUS 970 Pro Gaming/Aura board. The AI suite software lets me move the fan speed sliders but it never changes the speed of the fans, SpeedFan is set up correctly and although it sees the fans, changing the % never changes the speed. The fan speed changes only seem to take effect in the bios. Any help would be appreciated. Thanks in advance. Dylan.

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

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 !

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?

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!

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?

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!

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.

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

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 have asked myself: Do your Fans Spin at the displayed Speed when plugged in with a 2 to 1 PWM Split Cable (or PWM Fan Hub), or do you have to compensate for two fans on one Header? There are 2 ways Fans are powered: By Changing the Volts or through a PWM Header, which controls the Fans with pulse width modulation. By now, most Fans are PWM (and the question is about PWM) controlled My assumption: You don't have to compensate for it, because the fans are PWM controlled, where no extra Volts have to put through for more power.

Hi, I'm going to preface this by saying that I'm absolute noob to servos, PWM controls, and Raspberry Pi in general. I'm currently using Adafruit's 16 channel PWM Servo/LED HAT soldered to my Rasp Pi to connect two servos. The servos move but I can't seem to understand the commands and functions of the library they included in the guide: pwm.setPWM(channel, on, off) I've gotten them to move and then stop by putting the following in: pwm = PWM(0x40) pwm.setPWMFreq(60) pwm.setPWM(0,100,500) The frequency I'm assuming is the speed at which the servo moves. I understand what channel is, obviously sending the PWM signals to whichever channel the servo is connected to. However I cannot quite grasp what the on/off commands mean. All I know is that when they are set equal to each other (e.g. pwm.setPWM(0,500,500) the motor does not move. The on and off signals in that function don't seem to do anything at all and I'm confused on how to change pulse widths. Essentially, I want the first servo (a continuous rotation servo) to move a certain number of degrees (from what I understand this correlates to the ms the servo is running for), then the second servo (normal micro-servo) to move a certain number of degrees then back to its starting position, then I want the first servo to return back to its original position as well, completely sequentially. I was hoping somebody would explain the basics behind these functions, maybe how to write programs in order to complete the above, or show me another directory on Github (or something else) where a different directory and set of commands will work. It's import to note that the HAT is a form of the Adafruit PCA9685 chip. Here are some links to the stuff I mentioned above: Servo HAT: https://www.adafruit.com/product/2327 Tutorial: https://learn.adafruit.com/adafruit-16-channel-pwm-servo-hat-for-raspberry-pi/library-reference Continuous Rotation Servo: http://www.jameco.com/z/900-00008-Parallax-Continuous-Rotation-Servo_283039.html?CID=GOOG&gclid=CjwKEAiAn7HEBRDHwNqitoWqsQcSJAADWmI2dkPnipA2xvHFcIFgWEmdttSDgWUO_fXIvI3ryYRWNRoCcCDw_wcB Micro Servo: https://www.amazon.com/TowerPro-SG90-Micro-Servo-2pk/dp/B01608II3Q/ref=pd_lpo_21_bs_t_2/163-6850172-8295626?_encoding=UTF8&psc=1&refRID=WNWCW831X3V0AXMKDCM9

So the majority of fans out there now are these funky rounded shapes, that dont seal on radiators. Most of them are focused more on the sound profile than the performance curve. My radiator isnt in the same room as the screens, so i could care less about the sound profile. LED's, everything has LED's. Where did the plane Jane Square black fans go? They are few and far between on amazon. Can someone recommend some fans ment for radiators and no LEDS. High power and 4pin PWM.

Hi. I'm having two problems I cannot seem to troubleshoot: NZXT Hue+'s light strips will not light up but built-in light on the NZXT Hue+ will light up (and won't turn off!) PWM Fans cannot be configured for their speed, the only way to configure their speed is if I overclock my 6850K to 4.2GHz. This makes the fans run faster. What the heck?

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

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
