How to disable dynamic fan speed?

I have MSI 865P Neo. How to disable dynamic fan speed?

jpscwf: Personaly I always keep my fans on maximum anyway so I havn't tried saving settings at a lower level, better to have too much cooling anyway, rather than have your chip burn up..
netreaper: I may be wrong, but if your not running the corecell program then I don't think the fan speeds are adjusted. In any case, follow the instructions I gave above, and set both the fan speeds to maximum, that way you allways get the maximum cooling possible. Problem solved.

How can I control fan speeds in Win7 on a MBP-R for gaming?

I have a MacBook Pro with Retina Display. It has had Windows 7 installed and I want to play some 3D action games. How do I stop internal parts from overheating? I intend to use a USB cooling pad but that'll do nothing if the internal fans remain at idle speed.
The only Windows fan speed control utility I could find was the 4-year old SpeedFan which fails to detect the presence of any internal fans. I'm not impressed with the Windows community's failure to offer more and better than this tired old relic.
So the questions remain:
(1) Is the hardware still capable of automatically accelerating the fans as temperatures rise while gaming in Windows?
(2) What In Windows forces the MBP-R to lock the nVidia GPU into continuous duty and ignores Intel GPU?
(3) What control does the user have for (2)?
(4) How can I protect my MacBook Pro/Retina from overheating while playing PC games, apart from not playing games?

How can I adjust fan speed?

Hi; I have an HP Comaq Presario CQ57. The fan has gotten pretty loud; even when I first turn on the laptop and it is well ventalated in a cool area it is obnoxiously loud. Is there any way I can turn the fan off or adjust the fan speed? (I know it's risky so if you're going to tell me that please make sure you answer my question as well )

You can try a program called speedfan which is a free download
http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html
It's a pretty hard thing to use but it does give a readout of temperatures, which is useful even if you can't use it to adjust fan speed. Also go into the BIOS (F10) and see if there is a fan always on option and if so deselect it.
The fan is running fast for a reason. It is a symptom not a disease. Very likely the computer needs to be opened up and cleaned out inside. Post back if you want some direction on how to tackle that chore.

Satellite A500-138 - How to change the fan speed?

Hi,
I have a question how to I can change speed fan on my A500?
I mean with BIOS change power, I dont have advanced option on my BIOS so I cant change that... Any ideas?

Hi buddy,
You can change the speed fan in Windows Power Management. Therefore Toshiba Value Added Package must be installed but its already installed if you use the preinstalled Windows from Toshiba.
Open the Power Options: Start => Control Panel => Mobile PC => Power Options
Click on Change plan settings and in advanced settings you should see the option Cooling Method. There you can change between 2 different modes.

How to reduce cpu fan speed just by hardware?

Hi,
I have a K8N Neo4-F, AMD3200+ and "arctic cooling freezer 64 pro" as cpu fan. The rpm range of this fan is from 300 to 2200. I use "cool n' quiet" and "Smart CPU Fan Target with 40°C" as bios setting. When the cpu is idle ( ... just doing some typing or so on ...) it has a temperature of 32°C and the fan has ~950 RPM.
I think the fan speed is to high for this cpu load (< 5% and 1000Mhz CPU Clock). My expectation in this szenario is to have the cpu fan speed near the lower bound (300 rpm), but I don't know how to manage this (with just bios settings) ... any hints?
Thanks a lot ...

My point was you did what D.O.T. is supposed to do without using it.
Of course it's point is to auto-overclock the system to whichever degree it's set at. The problems come in because a lot of the settings it uses aren't always compatable with a lot hardware combinations. That's why it's best to come up with your own OC settings that are stable with your parts.
It's just like how the Nvidia/ATI speedup option seems like a good idea, but works poorly in practice.
Both are more useful to the marketing dept. in having more "why tech" features available to print on the outside of the retail box than they are to the end user.

27" iMac how can I adjust fan speed to cool more?

Is there a program in the OSX to check fans and temp?

Of course. To check temperatures, you can use Temperature Monitor > http://www.bresink.com/osx/TemperatureMonitor.html
To adjust fan speeds, use smcFanControl > http://www.eidac.de/ Be careful with fans because you mustn't set a fan speed higher than 2000 rpm. You will have problems in the future if fans work at a higher speed all the time

How is the ODD fan speed controlled?

I have a 2006 iMAC. The HD and CPU fans perform as expected, but the ODD fan 'goes like the clappers' even when the drive is not in use. I have read elsewhere the ODD uses the same sensors as the HD, is that the case? I have tried the SMC reset a couple of times but I guess this could be a hardware or firmware problem. The fans have 4 wires, I guess there is some sort of feedback system that tells the logic board the fan speed. I am an engineer, but new to MAC hardware. Any ideas chaps?
Many thanks, Andy

There is a thermal sensor on the optical drive that controls the ODD fan and either it is disconnected or there is something wrong with it.

How do I adjust Fan speed?

Hi Guys,
Recently I got my self a AMD XP 2600+ for my K7N420.
Before I had a AMD 1200.
Now the thing is, the fan used to always run at 4500 but now it only comes merely above 4000. How do I adjust the fan such that it goes at 4500 again?
Who can help me?

Is this the same fan?
Is it plugged into the motherboard or directly to power supply? Maybe direct connection for more power.
500 rpm probibly doesn't change much anyway.
What dcb is the fan rated? Maybe quieter just to leave it as is.

How to disable dynamic help

Tried hiding the window and resetting the prefs, getting annoyed by the gray text that pops up and I'd rather do a help search on a keystroke. Any tips on disabling the dynamic help?

I'm not sure which gray text you're talking about. There's 2 types of "popup" help in Flash Builder (1) ASDoc tooltips and (2) Adobe Help. Neither of them have gray text. I'll assume you're talking about the ASDoc tooltips.
1) Preferences > Editors > ActionScript Code
2) Uncheck "show in text hovers"
To bring up ASDoc tooltips on demand, press F2. Alternatively, you can use the ASDoc view (Window > Show View > Other...).
Hope that's what you're looking for.

Does anyone know how to reset the fan on a MacBook Pro 13-inch (Late 2011) to it's factory setting speed (Maybe Terminal may help?)

I have a late-2011 13-inch MacBook Pro running OS X Yosemite. (Standard configuration).
My problem is that I downloaded a fan control application and it worked perfectly, but it started to get annoying so I deleted it.
Does anyone know how to reset the fan speed back to factory settings (Maybe a command in terminal?)

How to control or know Fan Speed of the TBD

Thanks..

Not sure you can. I have never seen any app that would do that.

Hp dv9000(dv9392ea) How do you change the fan speed settings

Hi
I have now been looking for hours on how to change the fan speed settings for this laptop and all the things I have used do not work, has anyone been able to get it work or knows of away?
Please let me Know
Thanks

If you have a higher version it should include the earlier version settings.Usually each update is a rollup of previous changes plus newer.
If you are having serious overheating problems I would use a laptop cooling pad with fan/fans. Also,a less radical approach to the mod posted above is drilling some air holes in the bottom of case where the GPU is located. Adding copper shims shown HERE or HERE on his 'About ME' also keeps temps down.

[Solved] Asus L1366 mobo, cpu fan speed control

Hi, everyone,
I finally have this new core i7 system, to replace my old AMD athlonx2. I have one question about the CPU fan speed control.
I remember that in my old system, the cpu fan speed control works out of box, no configuration is needed.
But when I install arch 64 on this new i7 system, the cpu fan is running at its maximum speed constantly while the CPU temperature is modestly low. I know there is a wiki teaching how to do it.
However, I am just curious why it doens't work out of box any more? Does CPU fan control work for you guys out of box normally? especially the new Core i7 cpu users?
Please let me know, really appreciated it.
Thanks a lot.
Update: the issue is solved, see my last post, the solution is blacklisting: asus_atk0110, instead use w83667hg.
Cheers.

First off, it would be useful to know what the sensors-detect script actually reports.
Okay. How fan control works on Linux: First, navigate to /sys/class/hwmon
Each of these folders, i.e. hwmon0, stands for a sensors monitor / fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
Examples:
pwm1_enable shows if OS-level fan control is enabled (1) or disabled and in BIOS control (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
temp1_input interfaces can appeare too, if some of the chips have temperature sensors located somewhere. I *think* lm_sensors places the core temperatures it reads from CPU (the coretemp-isa-000X thingies) in one of the hwmon-folders too.
There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector, and all in the same hwmonN are managed by the same IC on your mainboard.
Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your CPU shuts down.
(If you see something likein0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)
If one of those interfaces can do something, OS-level fan control does work, if none of those folders contain a working pwm interface, fan control seems to be unavailable.
Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.
I don't know what you are using to control fan speed, there are many applications that use these interfaces, i.e. GNOME or KDE power managers, so I'm not sure what is happening:
IF: Windows 7 enables OS-level fan control and sets it the RPM to those you observed and you have nothing that provides fan control in Arch and so fan control stays at BIOS-level, which might also read out a different sensor / the same sensor differently or it might be more conservative in setting fan speeds altogether;
OR: You have something that provides fan control installed in Arch and it reads out a the wrong value supplied by lm_sensors and thus sets a higher fan speed.
Anyway, possible solutions I can think of:
Find out if you have some kind of fan control software and what it does. For example, I use the fancontrol daemon, I can't help you if you use something else.
The wiki mentions how to assign a fan speed to a certain temperature sensors. You might assign it to a different one. For example, there are no sensor chips on the mainboard of my EEE (no temp1 etc.) so I assigned the fan speed to the temperature reported by the BIOS via ACPI (those are in /sys/class/thermal, also no "device" subfolder on EEEs):
FCTEMPS=/sys/class/hwmon/hwmon0/pwm1=/sys/class/thermal/thermal_zone0/temp
You could also change the MINTEMP/MAXTEMP values to one higher than those you actually want to compensate for the effect of lm_sensors reporting temperatures that are too high.
It is currently not possible for a mortal user to change the coretemps lm_sensors reads, see this post, last paragraph.
There is a configuration file, /etc/sensors3.conf, you can change sensor names and adjust offsets here, but only for the monitoring chips and their sensors that are on the mainboard.

IMac (Late 2006) fan speed is 4600 rpm and nothing will change it

I just brought my iMac 24" 2.16GHz Late 2006 back from the Apple Store today and the ODD fan is running at 4600 rpm!!! The noise it generates is way too loud. It is comparable to the wind tunnel G4 I replaced. Any thoughts on how to lower the fan speed?
I took the iMac in on 12 Sep to repair microphone and video crashes. They repaired the mike and replaced the video card with an NVIDIA GeForce 7600GT. I picked it up on 3 Oct.
I have SMCFan and iStat Pro installed to monitor and adjust the minimum fan speed. I tried the usual troubleshooting steps (e.g., reset PRAM, Safe Boot, ran troubleshooting utilities, etc. to no avail.

David,
Looking through my old posts to refresh my memory, my face is red as *I AM* mistaken:O
http://discussions.apple.com/thread.jspa?messageID=4064287&#4064287
I was recalling that Intel iMac users were doing the wrong SMC result three years ago (actually they were doing the SMU reset that was for the pre-Intel G-5 iMacs), and that you and I explained to them the correct way - which is of course what you recommended above:D
Nevertheless, since there is no further risk of causing the fans to race in this instance, I would myself do the wrong SMC reset method, and if it does not work, turn right around and do it the way Apple recommends. This still might result in correcting the problem.
By the way, it was widely reported three years ago that the SMC reset was frequently not successful on the first attempt, so the alternative is to try this harmless procedure at least several times before giving up on it.

Disabling dynamic reloading

Hi, i'm using iWS 6.0 SP2 on solaris 8 and i don't know how to disable dynamic reloading of classes. I have tried to set the reload-interval parameter to a negative number, to set the class-loader classpath parameter to "", but it still reloads the classes.
The only thing i can think of is setting the reload-interval to a huge number, but there must be another way.
Juan

It's always Microsoft who gets blaimed ;-)
          First, I am almost certain that any OS will not let you copy a file if there
          is an opened file descriptor of the file owned by some other process.
          Second, luckily the class loader code that handles this is pure Java, so it
          takes advantage of garbage collection here: if there is a live reference to
          an object, it's not going to be freed under you.
          Hope this helps.
