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 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.

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

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 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.

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 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.

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!

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...

So ill be getting a MSI H110 ECO soon together with a NZXT s340 case (which includes 2 case fan). I was thinking of adding 2x140mm 3pin fan in the case for proper airflow but the motherboard I'm getting only has 2 additional fan headers. Will i be able to control all the fans using the MSI Total Fan Control app by using 2 spliiters (1 splitter to 2 exhaust 120mm case fan, and another spliiter for the 2 140mm extra fans im getting) I have read that 3pin fans can be controlled via voltage control but im quite unfamiliar in how the app works so any help for my case fan problem is really appreciated. Thanks in advance!

I have 3 PWM case fans and 2 PWM CPU fans connected to the motherboard. I am able to control 4 out of the 5 fans using speedfans settings. Speed fans read tab shows 3 controllable fan tabs listed as PWM1-3. The problem fan is listed in Speedfan as Fan5 (connected to sys_fan2) is always running at max and I have not the slightest clue how to control it. This fan is my exhaust fan and its seems to be running at 100% the entire time. Is there a way to control it? I haven't found anyway to control it as of yet.

Built a new machine. Everything working great and stress tested. Went to set custom fan profiles and ran into an issue. All my fans are PWM controlled and i'm trying to make a profile where they stay constant untill a certain temp then ramp up quickly after that. Went to test the profile and started the stress test, fans ramp up, then very quickly slow down again. They remain at the low setting while aida64 is running, which is a surprise. Not the end of the world, with my fans at 500-600 rpm, 10mins of aida64 stressing, my hottest core peaked at 83c on a hot day in a closed room. 280mm rads and noctua fans FTW. After looking here is the issue: Pwm fans are responding to "CPU" temp reading, not temp core readings (which is normal). The "CPU" temp reading will mostly sit around the temp of my highest core, or thereabouts, but when stressing, after 10 seconds or so the cpu temp reading will drop down again while the temp of the cores continues to climb. When i hit 83c my "CPU" reading was at about 55c or less, so of course the fans are staying at a low rpm. My first thought was that i could just set the fans to ramp up at 50c if the sensor is produving a consisyently low reading, but under normal conditions the sensor is quite accurate (closely mirrors the temp of the cpu cores) and so the fans go crazy everytime i open a program or chrome or what have you. Not the silence i built this thing for. Here is my question: Is this normal behavior for a temp sensor? I understand these things can be out by quite a bit when compared to coretemp, but to be off by 30c for a sustained period of load of 10minutes is wierd to me. It recognises the temp change accurately when the bench starts, so why does the reading go down while temps continue to climb in reality? I can watch this happen with any number of monitoring programs. Does this sound like a faulty sensor? Anyone else have a similar experience? Can someone with a similar maximus viii board replicate this? I would love to avoid dealing with asus customer service to get this fixed. Relevant System specs: Asus maximus viii hero alpha z170, bios 2202 6700k processor H115i cpu cooler with corsair link. (All fan are plugged into mobo).

G'Day guys! TLDR: Will this stuff https://www.pccasegear.com/wish_lists/649972/High End Current Build 18-11-16 work together Yes or no? Full Story: Alrighty, so, its come to my attention that my current computer just isnt handling games any more, its like 5 years old (Core i5 3550, 8Gb Ram, AMD HD7850...) so, i'm gonna replace it fully. I was going to go for 100% AIO water cooling, then i had the idea that i should just custom water loop which would give me the opportunity to add more graphics cards and what not. So I went to one of the best Computer parts storefronts online for Australia (PcCaseGear.com) and built a system that i believe will work with all the components for a simple Single loop with two rads, I've done some research into each of these parts and they should work, but i need a sanity check Parts List as Follows WISHLIST FOR CONVENIENCE: https://www.pccasegear.com/wish_lists/649972/High End Current Build 18-11-16 COMPUTER HARDWARE: MOBO: MSI Z170A Gaming M5 CPU: Core i7 6700K RAM: 2 x Corsair Vengeance LED CMU32GX4M2A266C16R 32Gb (2 x 16Gb) For total of 64 GB GPU: MSI GeForce GTX 1080 Gaming CASE: Thermaltake Core X71 Full Tower PSU: EVGA 700B (FROM CURRENT SYSTEM, Not in cost.)

Hi guys, My friend just got a new pc and I need a molex to PWM adapter because I am out of PWM ports. Where can I find a single molex to PWM adapter? If I search something it just brings up fan splitters and I dont need that. Just a single adapter head. I prefer it under $5 because and old 80mm fan isn't that much value.

Hello forum, So I unboxed the GPU and saw that the cable that connects the GPU and Radiator fan are connected, but since I opted for an Corsair ML120 instead of the stock fan, I decided to swap it out. So I got the new fan on the rad, but the ML120 is a PWM fan with a 4-pin connector and the cable going from the GPU itself only supports a 3-pin connector. It is possible to just let that cable hang there behind the mobo etc. and just plug my new fan on the rad to my PWM Controller (Using an Phanteks Evolv ATX TG) Any help is appreciated!

Hello Forum, New Build posts and is all good, but can't seem to get past boot cause of an CPU_Fan error (system is basically going nuts since it's thinking that no fan is connected). So I'm using the Phanteks Evolv and it wants me to connect it's 4 pin from the PWN Controller that comes with it into the CPU_Fan header on the mobo. I've done that and connected my H110i pump/cpu_fan 3 pin into the 4 pin waterpump header on the mobo. What's the solution here? Bear in mind I have a CPU_Opt (Optional too) that serves the same function, could I make use of that? @samcool55 @done12many2

I just came across speedfan and downloaded it to see what it will do with my system temperature wise. It runs cooler if I set the fans to high speed, but will this harm my fans/pc or other components? Or are there other downsides? Thanks in advance!

Can you just attach the PWM signal to multiple fans? Presumably it's a low power control signal. Using a multimeter on a Phobya 8 way PWM splitter it seems they've wired up all pins apart from the tachometer to all the fans. The tachometer is wired up to just one fan. Does the PWM signal need a boost if splitting it between, say 4 fans or is it just fine to splice the wires? Please note I'll be powering the fans another way.

hi like tittle says i have some problems i need to solve: 1)How should I make the connections of the two fans to be able to control the speed of them with CLink4? 2)How should I configure them on the motherboard? ***I clarify that one of the fans has 4 pins and the other 3 and both are connected to the pump*** ask this because I connect the fans as they are supposed to go and in the CorsairLink4 I do not see one of the fans (the fan that expels air out of the case) to change its speed so it turns very fast rpm. the temporary solution was to connect this fan to the motherboard and regulate it in this, but its speed remains constant at all times and although the CLink4 shows me the fan connected to the motherboard, obviously does not allow me to configure the speed from this. like I said, I can regulate the speed of the fan that draws hot air from the cabinet. well I'm waiting for your help thanks

Quick Question. I have a Frostflow 120. The frostflow have a 120Fan , a 120Rad and the cpublock. The 120Fan is a 4Pin fan header. The cpublock is a 3pin fan header. I bought a CoolerMaster Masterfan Pro 120 AirFlow, it came with a 4pin fan header. My motherboard has only two 4pin fan header labelled as cpu_fan and sys_fan. Can i actually put the cpublock into a 3pin fan header on my Thermaltake Commander FX, the 120Fan to the sys_fan , while the CM120AirFlow to the cpu_fan. Will the cpublock still function? Regards... This is a drawing

Hi everyone, I've recently started having an issue with a build I did a couple of months ago. I'll preface this by saying that I was originally using 3-pin splitters on all fans but the cpu fans then the problem changed slightly when I switched to 4-pin splitters. The fans I use are 2 corsair SP120s and 3 corasir HD120s, along with 2 CPU fans. After using the BIOS Qfan optimisation (ASUS Z270H mobo) my computer started failing to POST, only the CPU fans would run and while the LEDs lit up on the chassis fans, they would not run. I tried pushing them slightly to get them running but no joy. After restarting the computer a few times by turning it off at the wall it would eventually boot normally with all fans running. Now that I've switched to different splitters I'm only having this issue with the non PWM SP120 fans. I still have to do multiple restarts every time I want to turn my computer on to get the fan running so the computer can boot. It is also having this issue when I try to wake it from sleep. I have also tried using AI suite 3 to change fan settings and I've gone back and forth multiple times resetting and reoptimising to the point of madness. Could it be a voltage issue to the SP120s? If so please could someone help me work out how to fix it? Specs ASUS Z270H mobo i5 7600K Corsair H75 cooler MSI GTX 970 GSKILL Trident Z RGB 8GB x2 EVGA 650W G2 Windows 10
