monitor (I think there's one in the Asus software), or else it runs the risk of overheating during gaming. Asus m32 series adjust fan speed install#The thing is if I leave the fans on low speed I should really install a temp. In the summer it's okay, the cool air is welcome, but in winter it's a pain. I've put them both on the low setting but it's still really shifting alot of air, put it this way, I'll need to buy a pair of slippers as my feet get cold with it. Only one of them is accessible from outside the tower though which is a pain. Asus m32 series adjust fan speed manual#It's a P5B Rev1 04G but I can't see if it's a BN model, I can't even recall if I got the deluxe or not, I'll need to go dig the manual out.īoth extractor fans are plugged into the PSU, and they both have an extra wire with a 3 speed switch on them. smm 31a3.Okay here's what I've figured out so far using the Qs/tips above. To give control back to BIOS for some reason do the following procedure: # sudo. This setting will remain even if the system is rebooted. Now BIOS fan control should not override fan settings. # i8kfan 1 1 (This will set fans to slow speed) Set the fan speeds: # i8kfan 2 2 (Listen as this will set fans to maximum speed) Asus m32 series adjust fan speed code#Extract the source code and cd into the directory: # tar xvf i8kutils_1.33.tar.gz ![]() Asus m32 series adjust fan speed download#Download the source code and compile a program (SMM) to do this: # sudo apt-get build-dep i8kutils Override the BIOS to keep it from interrupting custom fan settings. Download and install i8ktutils: # sudo apt-get install i8kutils This procedure had already been posted by someone: My computer's initial temperature was 105F degrees and about 10 mins after using these steps (fan setting = 2) the CPU/Core temps dropped to 96F degrees. I have a Dell Latitude e4200 and the following worked for me because the BIOS was overriding i8kfan setting. You can obtain 1.41 on i8kutils launchpad page. The version 1.41 contains smm, while 1.43 no longer contains it.Īs of 1.42, smm is provided as a kernel module only. If your distribution already upgraded to the latest version, you'll have to fetch an older version manually. Smm is no longer included in latest i8kutils. *2: for verifying this, run pwmconfig: sudo apt-get install fancontrol, sudo pwm-config will tell if a pwm-capable fan is present or not Note about smm If you want to verify that your hardware lacks it, follow instructions here: *1: I've seen an official source on this, can't find it right now. BIOS fan control can be enabled again with $ sudo. Note: This is a setting that will persist reboots and power-off's. Try by setting speeds with i8kctl, listen for the fan and make sure the speed persists. Now, BIOS fan control should be disabled. Run smm with argument 30a3 to disable SMM fan control: $ sudo. If on a 64-bit system: $ gcc -g -O2 -Wall -I. What we'll do is to download the source code of i8kutils, compile the program smm, and run it with an apropriate argument to disable BIOS fan control by writing to SMM registers.ĭownload packages needed for building: $ sudo apt-get build-dep i8kutilsĭownload i8kutils source code, extract and enter directory (exact names depending on i8k version): $ apt-get source i8kutils I8kutils includes the source of a program smm but the i8kutils package does not include the compiled binary. Also, all reports on trying this have indicated success in disabling the BIOS fan control. However, I've seen no user reports on this causing trouble. Warning: see the warning in top of smm.c. Luckily there is a way to disable BIOS fan control by writing to SMM registers. If it works, but somewthing else is fighting back on the setted speed (reported by many users on Dell Latitude laptops), this is due to scheduled SMM sessions setting the fan speed back. Install i8kutils: $ sudo apt-get install i8kutils You suffer from that as well according to a previous comment. Several users report success on their Dell Laitude laptops as well (I'm one of them, on a Dell Latitude E7440) - however, a trick is often needed to get rid of interfering BIOS fan control. ![]() However, there's a package called i8kutils that is written to control the fan on Dell Inspiron laptops through SMM BIOS. as a consequence, the fancontrol/ pwmconfig program won't work.as a consequence, trying with ACPI boot parameters and the like will failĭell Latitude laptops, as far as I know, lack pwm controllable fans (*2).Two common and straight-forward means of controlling the fan on laptops are through ACPI and through PWM pins, however, unfortunately:ĭell laptops lacks ACPI fan control capability (*1) Asus m32 series adjust fan speed full#For completeness, I'll include some general notes on fan control on Dell laptops, and full instructions for i8kutils. ![]() You'll most likely be able to solve your problem with something else overriding your i8kctl fan commands by the method given in this answer. ![]()
