The main feature I used was the custom fan curves with custom temperature sources. I used it to bind my case fans speed to the hottest component of my PC, my GPU. (My BIOS only supports CPU temperature as a temperature source for the PWM fans). I searched around for an alternative software with this particular feature and only found a paid option (Angus Monitor). However, I also came around this: https://github.com/openhardwaremonitor/openhardwaremonitor https://github.com/LibreHardwareMonitor/LibreHardwareMonitor The first link is an original project which could be downloaded here https://openhardwaremonitor.org/, but just like SpeedFan, the project is not updated anymore. However, thanks to the code base being open sourced, there are a couple of active branches, LibreHardwareMonitor being the best one I found, supporting my MSI Z390 Edge AC board and being updated regularly. OpenHardwareMonitor is divided into two parts, an API to interact with your hardware ( CPU, RAM, Fans... ) and a UI. The existing UI is a HWMonitor clone that allows to set a manual fan speed to any fan, but no temperature/speed fan curve here. ( sigh ) So I decided to make my own lightweight application with the OpenHardwareMonitorLib API, and here is what I got so far... Current features: OTA update Multi-config support with quick-switch from tray icon Dark/light mode + colors Graph fan curves Linear fan curves Flat fan curves Mixed fan curves Sync fan curves Custom name for each fan / curve / control Material UI ( thanks to http://materialdesigninxaml.net/ ) Smooth fan speed transitions Custom temperature source Automatic or manual matching between your controls and fan speeds Activation% (dead zone) for each fan Saves your current configuration and reload it on startup Board support is updated whenever the API gets an update! Please note that this is a small personal project. It works great for my needs but I didn't test it on a hundred different motherboards. Take it as it is. If it works on your current setup, well you got your fan control situation sorted at least until you change your motherboard! If you want to help me out a bit or give me feedback, I included some links/button in the left hamburger menu out of the way to send me an email or to pay me a ... or . I will also keep an eye on this thread to see how it goes. Confirmed compatibility list from members Enjoy!

Hello So, I recently got the SpeedFan Software, which is super awesome and I had it for a while for my CPU/AIO fan but when I tried it for my GPU, it detects 2 Sensors(for 2 fans), but I can only control one fan, so I started the Setup Assistant again and now booth fans of my GPU stoped... And won't react to the Curve, when I Exit the Software the GPU Fans start to spin again... So I guess the start and stop values got detected wrong... So for me it makes no sense that the Start and stop values are on 0 on the right: Specs: RTX 3070 i7 13th Gen AIO: Artic Liquid Freezer II 360 Windows 11 I hope I'm not too wrong... Thanks for your help!

I have been having issues with my GPU fans not working to their max. Say I was playing Half Life: Alyx, my fans wouldn't go fast enough to cool my GPU. While playing Half Life Alyx, my GPU hit 170 Degrees Fahrenheit. They used to go at full blast, but ever since I had to factory reset my PC, I haven't been able to access OC Controls (Thermal Controls) In Alienware Command Center (AWCC) and my fans won't go how ever fast enough they need to, causing my PC to overheat and literally BURN my hand on touch. Back to SpeedFan. I have been going into the "Advanced" tab to find my motherboard chip and set the fans to be operated by software (SpeedFan in this case), but I cannot find the correct Chip, all I have in the drop down menu is "INTEL CORE at $0 on ISA", "HD0 (1024.2GB) at $0 on SCSI", and "GeForce Video Card at $0 on PCI". Nothing relates to fans or anything in that manner after selecting an option. Any Idea how to properly use this software?

I have an Asus VivoBook X509FJ....I would like to control my fan speed for different occasions Notebook fancontrol was of great help with my old dell...but unfortunately I am not able to find configs for my new Vivobook (tried all configs of asus laptops in the application) I tried the methods mentioned in github https://github.com/hirschmann/nbfc/wiki/How-to-create-a-NBFC-config But I am not able to get what they are asking me to get IS there anyone who has managed to get custom configs for this laptop or is there any place I can get custom configs? Or is there any other app other than speedfan which could control the fan speed?

Hey, I was looking in SpeedFan and there is a tab called xAP. What is it, and what is/can it be used for?

Greetings. Completely new here, to this site and to help forums all together. (Hope this question is posted in the correct category.) Just recently download SpeedFan to give it a try. I looked up a tutorial to make sure I got everything working correctly. I launched up a game to check in game temps. CPU in near 100c at around 50% cpu usage. My CPU fan is maxed out and can't keep up. (see FAN1 @ 1900RPM) I restarted and check bios for temps. Same story. I attached some pictures. Mobo: GA-Z97X-Gaming 3 CPU: I5-4690k (have not touched any oc settings) Questions: What temperatures are too hot? What's the minimum and the maximum?. I've built and been using this computer for almost three years with no problems. Do you think my stock cooler or thermal paste was installed incorrectly? Hard to believe my cpu has been running that hot with no issues for three years. How did this become a problem? What is temp3? It usually is running hot with my CPU. SpeedFan says it's on chipset "IT8620E". Not sure if that is related to my cpu. Is that a part on the mobo? If so, how do I fix that? If it's not part of the cpu, an after market cooler won't help? I heard SpeedFan gives wacky temperatures readings, could this be whats happening? How do I be sure? I bought a 212 EVO for my CPU just to be sure. Hope It can fix my problem. It hasn't come yet. Will update when it gets here. (Check links for screenshots. I tired to attach them twice. Kept getting errors -200 "Problem processing upload file" Your going to have to open the images in newtab an manually zoom in to see them correctly. Sorry) - http://s1259.photobucket.com/user/Slouch00/media/Screenshot 167_zpsctbpvc9d.png.html - http://i1259.photobucket.com/albums/ii558/Slouch00/Screenshot 166_zpsdictzbja.png - http://i1259.photobucket.com/albums/ii558/Slouch00/Screenshot 160_zpslnylkobu.png -Slouch

I've been using SpeedFan for a while now. I've used Asus fan expert before and I find that their is a lack of advanced options available. You might ask why I've been using it if I think it sucks, well that's because I can't find a better alternative. However, I don't like to settle for "well that'll just have to do"! With my setup, I have a whole load of issues: - Out of the CPU Temps only CPU core temps are shown in SpeedFan (which causes fans to increase and decrease due to the individual cores fluctuating naturally) The temperature that was listed as "CPU" actually turned out to be the chipset temperature. - Can't control GPU fan. - Lack of updates - Crashes and other issues. The first two points are my main issues! If anyone can suggest an alternative to SpeedFan I would be very grateful Below is the info SpeedFan gives out when it is opened up: Win9x:NO 64Bit:YES GiveIO:NO SpeedFan:YES I/O properly initialized Linked ISA BUS at $0290 Linked Intel Sunrise Point SMBUS at $F000 Found nVidia GeForce GTX 1080 Linked nVidiaI2C0 SMBUS at $3D403E3F Linked nVidiaI2C1 SMBUS at $3D403637 Linked nVidiaI2C2 SMBUS at $3D405051 Scanning ISA BUS at $0290...

Do I have to keep my SpeedFan program open at all times, or will it monitor temps and keep fan speed going accordingly while it's not technically open? Also, can I run SpeedFan on startup? There are a couple of videos but I'm just wondering.

To adjust radiator fans based on CPU temperature, is it better to use a MAX of all of the core temps or just use the one labelled "CPU"?

I use Speed fan to change speeds of my case fans (1x 200mm and 2x 140mm) It used to work but when I tried to make it change fan speeds based on GPU temps rather than CPU temps, it doesn't work and just puts fan speeds to 0% or 100% but nothing in between. When I change it like it used to be it does, same thing. What can I do?

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.

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!

I have a specific problem and I don'te really know what to search for so I want to ask you. Basic info: I use windows 10 I work/play on a standard account recently converted from an admin account I have a second account that is now admin I want to run speedfan as soon as possible after I turn my PC on Speedfan needs elevated priviliges to run I don't want to have to enter my admin password to open it My autostart is brocken since switching from Windows 7 to 10 but I don't really mind since I have succesfully gotten it to work with windows task planing. I created a task that would trigger on ech system start and user login unless the task was already running. This task starts speedfan.exe with elevated privileges but t he problem iis that it doesn't run when I login to the standard user. It works fine if I log into the admin account. I tried changing the user account used to execute speedfan to admin, to local admin group to the user that it was run on ... and nothing worked. What am I doing wrong. Do you have any ssugestions? These features seem to be more oriented towards administrating a company full of windows machines to do this and that Sidenote: I have a bunch of 32 digit hex character named tasks show up in a message every time I open windows task planing saying they are no longer available or something. I don't want to delete anything because I don't know exactly know what i am doing here. Any tips for that one?

Speccy reports that my cpu is around 35 degrees however speed fan reports that it is around 127 degrees. For some reference this is while idle, my cpu is an i7 6800k with a hyper 212 evo in a mid tower with not great airflow. Also i have recently been having some crashing issues when playing intense games such as pubg or overwatch and my thoughts is that heat is the issue and specifically my cpu overheating.

Hi there, I currently use the NZXT Kraken X62 to cool my CPU. I have 3 NZXT Aer RGB 140mm fans plugged into the Kraken X62 (1 for case exhaust, 2 for radiator). I use NZXT CAM to control them. But the fans are too loud for my liking, so I would like to replace them with 3 be quiet! Silent Wings 3 PWM fans. I also have 3 intake fans that I would like to replace with be quiet! Silent Wings 3 PWM fans as well. Question: What would be the best way to control all of these fans? I am mostly concerned about the temperature of my AMD Threadripper 1950X. I have an ASUS ROG Zenith Extreme motherboard. I was thinking of using the included PWM fan hub of my Phanteks Enthoo Luxe TG case. It can use all 6 fans and be plugged into the "chassis fan 2" header on my motherboard. And then use Speedfan to control the fans, because controlling fans through the BIOS results into big RPM spikes and downfalls. So fan hysteresis would be important to me. Let me know what you guys think. Thanks!

Hey guys, I have gigabyte gigabyte 990fxa-ud3 and I have AKASA FLEXA molex (this) connected to system_fan 4 pin on my motherboard and into it I got connected 4 fans but I can't control my fan speeds in speedfan even if I choose correct bus in advanced options and set every pwm on manual. I can regulate my cpu fan there but not my other fans. Any ideas?

Warm greetings everyone, I've seen a lot of discussion as to the use of SpeedFan to control a specific fan/set of fans. I have an ASUS STRIX 270G miniATX and set up SpeedFan to control the CPU fan header in "manual" mode (I was finally able to get to this point by setting Q-Fan in UEFI/Bios to "Disabled" for control of the CPU fan header). Now that I can set the fan control to remember "manual", I have linked the specific CPU fan header to run based off of the GPU temperature and set a custom curve. In the main page of SpeedFan, I can see that the program is attempting to control the fan speed via the percentage setting in accordance to the GPU Temperature Vs. Fan Speed curve I created. However, even manually adjusting and adjustment to the curve for 100% fan setting at idle temperatures produces unsuccessful results in fan speed changes. I have come to the conclusion that there is something still running in the background other than the bios (disabled Q-Fan control as mentioned) which is still controlling the fans. I have uninstalled Ai Suite 3 and Fan Expert and removed any residual executable processes still running ("AsusFanControlService" and "AsSysCtrlService") in the task manager. There must be something else overriding attempts from SpeedFan... but what? I am new to building computers (just built my first one and I adore it) so I don't have a lot of experience with the nitty gritty details. Would one of you experts in the subject matter be able to point me in the right direction? Thank you in advance and I look forward to learning from this community. Best Regards.

i want to control my fan speeds but speed fan isn't showing any speed controls nor is it showing any fan speeds both sections blank is there any other fan control software that i could try out? i updated the bios for my motherboard no difference. system specs intel core i-5 3470 ivy bridge 10 gigabytes ram ddr3 gigabyte geforce gtx 1050 ti 4gb 2 hdd, 320 laptop hdd for boot drive in the bios there is a way to control the idle fan speed for the cpu but nothing else

I got another one of these fan distribution cards (because the last one wouldn't power 2 slots): http://www.performance-pcs.com/modmytoys-4-pin-pwm-low-profile-power-distribution-pcb-8-way-block.html And I tested the power distribution with a 9V battery and I noticed one fan not working, so I unplugged it, replugged it, and then another fan stopped receiving power. So I did the same until all fans had power and were spinning. I closed and powered up my PC and everything was working wonderfully until I opened up SpeedFan -- like usual after I boot up -- and the 8 fans on my radiator wouldn't slow down like they normally would with the previous distribution card. So I thought, "New hardware, so different fan control" so I rewatched this: https://www.youtube.com/watch?v=1OkBRELqEgM and did all the things Jay said the best I could except there wasn't an option for "Software Controlled" so I kept the options to "Manual" like they were before and I removed the previous fan controllers because they weren't working and tried to set up new ones but this was difficult when I don't have any options for PWM, only Aux, Aux1, and Aux2 because all my fans are on a PWM distribution card. I have a suspicion that the PWM connection to the cable that connects the card to the motherboard is acting up. Does anyone have any idea on what I should do to fix this like redownload (maybe an update) SpeedFan and start anew or something else? I should note that I've never had anything connected to the "CPU_Fan" header on the motherboard only on the 2 Chasis headers ( One 6 Fan Distribution card and one 8 Fan).

Hi, everyone,I've been on a quest to achieve optimal PC cooling. My mobo is a Maximus IX Formula, and after properly connecting all the fans to what I consider to be the ideal setup, I realized that Asus' software (AI Suite/Fan Xpert) simply wasn't gonna cut it (jarring jumps in fan speeds even when setting fan curves at the BIOS level; also, no way to set fans to GPU temps).So I looked into SpeedFan. This guide has been really helpful, but I still have some questions. First, here's my cooling setup: Case: NZXT S340 Elite; CPU: i7-7700K + Corsair H110i w/ 2x Noctua NF-A14 in push, at the front; GPU: EVGA 1080 Ti SC2 Hybrid w/ 1x Noctua NF-F12 in pull + 1x Corsair ML120 in push, at the back; Exhaust: 1x Corsair ML140 at the top. Here's how everything's connected to the mobo (headers): CPU_FAN - NF-A14CPU_OPT - NF-A14 CHA_FAN2 - ML140 CHA_FAN3 - ML120 AIO_PUMP - H110i* H_AMP - NF-F12 *The H110i has a non-variable pump, so I plugged its 3-pin cable into one of the two non-PWM controlled headers. That way, the pump should always run at full speed.I already identified all fans on SpeedFan. They're CPU (both NF-A14s, since the CPU_OPT header mirrors CPU_FAN), Aux (ML140), Aux1 (ML120) and Aux3 (NF-F12).There's still Sys and Aux2, which were at 0 and 100%, respectively, when I first started SpeedFan, with no way to change those values (even after configuring all PWM modes to manual, as per the guide).I assumed that Sys was the H110i's pump speed, so I set that to 100% as both minimum and maximum values, even though the pump is already connected to a non-PWM header, as mentioned.I have no idea what Aux2 refers to. I can't tell if it's the GPU's AIO or the hybrid card's fan (which cools the VRMs and even with the values at 100%, isn't spinning when idling).Another question: when selecting which fans to respond to each temperature, the guide shows changes being made only to Core 0/CPU, with Core 1 left unchanged. I have Sys, CPU and Cores 0, 1, 2 and 3 listed. Sys is already set to 100% regardless. I selected CPU fan for the rest, assuming I have to do it for each core, besides the CPU label itself. Is that the right way to do it?Any help is appreciated. Thanks in advance!

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

Today I installed Speedfan, every time I open the software, my cursor can't move, both with my trackpoint (the red dot on thinkpads which moves the cursor) and my trackpad. It only stops once I restart my computer.

I need a software solution for controlling fan speed on my server. There's no option for fan control in the BIOS, I guess because it's an Asus H81 board with a very basic BIOS. I tried Speedfan within Windows but I couldn't get it to detect any fans. I can't find any other options anywhere. Do any more exist?

Hello LTT users! I have some questions regarding the SpeedFan software so lets get straight to it. Do i need to run SpeedFan in the background for it to control my fans? Can i make a fan react to my cpu temperature and my gpu temperature at the same time or will they fight eachother? How do i know what fan it is im configuring? the names are just to complicated and i cant relate them to any of my fan names (as far as i know). Will SpeedFan override my other fan configurations or do i need to uninstall the other softwares?. I use MSI Afterburner for GPU and MSI Command Center for CPU and System fans. Is SpeedFan really the program to go with? its really complicated imo. Qustions not regarding SpeedFan: How do i know which one of the connectors i should plug the fan into on my motherboard? (x99 SLI Plus) i just plugged them into random 4 pin connectors when i installed some new aftermarket fans. I got two new Noctua fans that should be runnning at 1500 rpm but one of them is only running at 1400 rpm, can this has anything to do with where i plugged them into my motherboard? Noctua users. Do you recommend leaving the vibration pads on or off?
