HDD Fan control is useful when you have one or several hard drives with one or several fans close to them, and do not want to let the motherboard control the fan speed, because it does so either statically, or using

Adjusting the speed of a CPU fan is essential for maintaining optimal system performance and preventing overheating. There are several methods to adjust CPU fan speed.One way is through the computer's BIOS settings. As mentioned earlier, accessing the BIOS and locating the fan control section allows you to manually adjust the fan speed or set it to a specific mode based on temperature thresholds.Another option is to use software tools. There are many third-party applications available that can monitor and control CPU fan speeds. These tools often provide more advanced features than the BIOS, such as custom fan curves and real-time temperature monitoring. Some popular fan control software includes SpeedFan, HWMonitor, and MSI Afterburner (although primarily designed for graphics card overclocking, it can also control some CPU fans).For systems with a 4-pin CPU fan, the motherboard may support PWM (Pulse Width Modulation) control. This allows for more precise fan speed control by varying the duty cycle of the electrical signal. The motherboard's BIOS or software tools can be used to configure the PWM settings for the CPU fan.It's important to note that when adjusting the CPU fan speed, you should consider the cooling requirements of your system. If the fan speed is set too low, the CPU may overheat and cause damage. On the other hand, setting the fan speed too high may result in excessive noise. Finding the right balance is crucial.In addition to adjusting the fan speed, you can also take other steps to improve cooling. This includes ensuring proper airflow within the computer case by organizing cables neatly and adding additional case fans if necessary. Keeping the computer's interior clean from dust can also help improve cooling efficiency. adjusting the CPU fan speed can be done through BIOS settings or software tools. By finding the right balance between cooling and noise, you can ensure optimal system performance and longevity.

Make estimates only on the temperature, not the actual temperature readings, but in fact, it is very, very accurate! #11 Thanks for the speedfan tip. I didn't catch the dell check box. I've been trying everything because my cpu fan started spiking up and down about every 10 seconds. Just curious , now that I can control the case and cpu fan what should they be running around. I have a dell studio xps 8100 with a i-5 #12 Thanks for the speedfan tip. I didn't catch the dell check box. I've been trying everything because my cpu fan started spiking up and down about every 10 seconds. Just curious , now that I can control the case and cpu fan what should they be running around. I have a dell studio xps 8100 with a i-5 These Dell systems have a very odd fanspeed control system. The fan itself is capable of variable throttle as I rewired a Dell Optiplex 745 case/CPU fan to nearly outdo single loop watercooling units in unison with a Hyper 212 EVO, but the fan controller in the Dells is 3 speeds: Jack squat, Half speed, and RUN FOREST RUN!!! (the last one is only used if the CPU exceeds 50 to 60 degrees celcius...a healthy, happy 745 almost always sits on top of the half speed notch 24/7.) My suggestion is not to touch the fan speed controls until you replace the thermal paste, but keep the program anyways whether or not the thermal paste replacement/fan adjustments work to see what temperatures your CPU actually IS reaching.If you HAVE already replaced the thermal paste within 2 years time, then just lemme know and I can show you how to make a fan speed profile.

Review the fan configuration settings. Particularly note down how you have the CPU_FAN header set up in case you want to re-configure it the same way.Now, click on the option about mid-screen to set ALL fans to Default settings. This will ensure that all are using automatic fan speed control (not any custom curve). Now, go though each fan header in turns and check its configuration. In each case it should be using the normal automatic control. For the CPU_FAN header, IF your CPU cooler is a 4-pin fan, set it to use PWM Mode. For the PUMP_FAN header, same thing - IF that fan is 4-pin, set the header to use PWM Mode; but IF the fan is 3-pin, set the header to DC Mode. Now, for all the other SYS_FAN headers is seems from your post that thyey all are of the 3-pin design, so set all their headers to use DC Mode. When finished, remember to SAVE and EXIT to save the settings and reboot.If that one fan still does not work it is faulty. I do find it VERY puzzling that you say it is not running and yet its header claims to have a fan speed. Well, after those configuration changes, has anything changed? #3 Go to manual p. 62 to review the fan configuration settings.

HDD Fan controlHDD Fan control is a command line tool to dynamically control fan speed according to hard drive temperature on Linux.This has 3 benefits:it allows maintaining you hard drives in the ideal temperature range to have maximum longevity and avoid overheatingBecause fans will slow down or stop when not needed:it minimizes noise generated by the fansit also minimizes power consumption at the same timeWhen is this useful?HDD Fan control is useful when you have one or several hard drives with one or several fans close to them, and do not want to let the motherboard control the fan speed, because it does so either statically, or using a temperature sensor unrelated to the real drive temperature (either on the CPU or on some other place on the motherboard).The ideal use case is for a NAS with several hard drives, a low power CPU (ie. ARM or Intel Atom) with passive cooling (no fans), and a chassis with fans close to the hard drive. It that case the CPU will generate less heat than the hard drives and it makes sense to control fan speed according to the main heat source.FeaturesCan be started in daemon modeCan control several fans and/or several drives with a single invocationCan automatically spin down drives after a customizable period of inactivityCan adapt to different fan characteristicsCan be set to stop fans or run them at full speed at customizable temperaturesCan be configured to never set the fans below a certain speed (useful if the fans controlled by HDD Fan control are the only ones available in the chassis)PrerequisitesA Linux distributionA least one SATA hard drive, that supports:Temperature queryingPower state queryingA motherboard which:exposes to the OS a PWM to control fan speedexposes to the OS a sensor to query fan speedMost motherboards and SATA drives fit these requirements.InstallationHDD Fan control requires Python >= 3.4.Distribution packagesSome Linux distributions have a hddfancontrol package available in their repository:Arch Linux (AUR): hddfancontrolFedora: hddfancontrol (thanks to TC01)From PyPI (with PIP)If you don't already have it, install pip for Python 3Install HDD Fan control: pip3 install hddfancontrolInstall hdparm and hddtemp.On Ubuntu and other Debian derivatives: sudo apt-get install hdparm hddtemp.From sourceIf you don't already have it, install setuptools for Python 3Clone this repository: git clone HDD Fan control: python3 setup.py installInstall hdparm and hddtemp.On Ubuntu and other Debian derivatives: sudo apt-get install hdparm hddtemp.To query fan caracteristic, you may also need pwmconfig.

Fan control warningManual fan speed control is an advanced funtion and should not be used if the BIOS of your mainboard does offer you an option for fan control. Setting a fan to a low speed value may lead to insufficient air flow inside your PC and therefore to insufficient cooling of its components. This may damage your processor and/or lead to other problems, including but not limited to, damage to your system components (e.g. your motherboard or memory), system instabilities, data loss, reduction in system performance, shortened processor and/or system component life and in extreme cases, to total system failure.THE VENDOR OF ARGUS MONITOR DOES NOT PROVIDE SUPPORT OR SERVICE FOR ISSUES OR DAMAGES RELATED TO MANIPULATING THE FAN SPEED OF YOUR PC, AND CANNOT BE HELD RESPONSIBLE IF YOU DAMAGE ANY OF YOUR SYSTEM COMPONENTS BY USING MANUAL FAN SPEED CONTROL. YOU MAY ALSO NOT RECEIVE SUPPORT OR SERVICE FROM YOUR BOARD OR SYSTEM MANUFACTURER.PLEASE MAKE SURE YOU HAVE SAVED ALL IMPORTANT DATA BEFORE USING MANUAL FAN SPEED CONTROL.ONLY ENABLE THIS FUNCTION IF YOU REALLY KNOW WHAT YOU ARE DOING.In case you decide to use this function please also consider to set a fan speed warning threshold, which can be done in the settings.
