Increase Fan Speed

How can I increase the internal fans in my computer? I only want like a 10% or so increase because the thing just gets so darn hot when I play games...Is there an easy way to control it so I can even create a script that when I have the game loaded it will increase their speed 10-20% and when I quit they will revert to default?

Download and install SMCFanControl: http://www.versiontracker.com/dyn/moreinfo/macosx/31029
With this program you can increase the default fan speeds. You can also create multiple presets for instance one for a slightly increased fan speeds which you may keep it at during normal use. Then have a another higher setting that you set it to when you are going to play games. This will require you to manually change the setting each time. It's easy enough to do though.
If you are not already I would recommend installing iStat Pro or Temperature Monitor so that you can monitor your iMacs internal temperatures. This will help you to determine the best settings for your fans.

Any possibility of increasing fan speed on dv5 1045tx

I want to increase the fan speed because my dv5 1045tx gets too hot. On idle my cpu ranges from 45Cto 55C and my gpu stays at about 60C. When I play any game(like cod4 on highest and lowest graphics settings) my laptop's gpu goes up to 91C to 98C and cpu going to about 80C to 90C. Old games like prince of persia warrior within bring my cpu up to 95C to 98C. Without being able to increase fan speeds, I lost my freedom of playing games. Can someone please help?
Used speedfan to check temps

Many times a laptop overheating is directly related to the cooling of the processor. The main culprit is the fan. The fan sucks in air from the bottom and blows it out the side. It will also suck in hair, dust, and other debris. That stuff often gets trapped by the heat sink and over time builds up in a layer which chokes off the cool air going to the processor making the fan work harder.
Check this out:

What I recommend is getting some canned air and blowing out the vents in the side and bottom of the laptop. If after doing this you still have problems with over-heating, and your laptop is in warranty, you can take your laptop to a HP Authorized Service Center and ask them to clean the fan and heatsink. You can check your warranty here:
http://www13.itrc.hp.com/service/ewarranty/warrantyResults.do?admit=109447627+1286541891570+28353475
If it is out of warranty, consider searching for the maintenance manual for your specific model, in the manual there are schematics for taking apart the laptop. Cleaning the fan is much easier that removing a motherboard, so don't feel to intimidated by the idea. Also you can remove the heatsink and then remove the thermal grease and apply a new layer which also helps alleviate heat related issues.

How to increase fan speed on HP pavilion dv7

i have a major problem with my fans on my pc. It often reaches 80-90 degrees celcuis, when i have been playing a fairly simple game for about 20 minutes. does anyone know what to do? and it dosent seem like i can increase my fan speed in any way. i have been trying almost everything i can find on the internet. please help

Hello themanafreak. I understand your notebook is getting warm during use.
First, you should ensure that the cooling system of the notebook is free of dust and debris but cleaning the notebook as per these instructions.
Also, another good step to take is to ensure that you have the latest version of the BIOS installed. I can locate the latest BIOS for you if you provide me with your product number. This document can show you where the product number is located. Finally, I do not know of a way to increase the fan's speed itself but you can set the fan to "always be on" by doing the following.
Reboot your computer and press F10 until the BIOS loads.Navigate to the System Configuration section.Ensure that "Fan Always On" is set to enabled.Navigate to the Exit section and save your changes.
Have a great day!

Increased Fan Speed While Playing Halo 3

Hi Sir,
While i was playing a demo version for Halo 3 on my macbook, the speed of the fan increased. Is that normal?
And Do you recommend me to use the macbook to play the game or should i buy imac for it?
With Regards
Vikram

Yes, high fan speed should be expected for a high demand game.
The Fans max speed is about 6,200 RPM.
If you would like more info about your system you can get the iStat Pro Wedget (free)

Increase fan speed on Intel Core Duo Mac mini?

I have owned a PowerPC G4 based Mac mini for some time now. It's been (and continues to be) a great little computer.
Just recently I bought the Intel Core Duo version. It too seems like a great little computer.
However, I've got to admit that the amount of heat the Intel version puts out is staggering. The internal hard disk claims to be running around 119-126 degrees Fahrenheit. I put a thermometer near the vent on the back and it topped out at 120 degrees F. The bottom pad is nearly too hot to touch. This computer is running a distributed computing project.
Far be it from me to second guess Apple's engineers, but the fan is never turning very fast at all on the Intel mini. It is running, though, and appears to be doing as it was designed to do. (I've seen my PowerPC machine get to rip-roaring during the summer.)
Running the Apple Hardware Test shows that the Intel mini's fan can speed up quite a bit. I'd like to know if there's a way to request a higher fan speed outside of the Hardware Test. I know I could pop the thing open and just "forget" to reconnect the fan speed sensor wire to command the fan to run at full speed, but I don't want to invalidate the warranty.
Maybe I'm being silly, but I prefer that my computers be moving enough air from them to keep things cool regardless of noise level.

The smcFanControl utility is what ended up solving this problem. Turning up the fan speeds just a little bit resulted in a very noticeable cool-down.

Increasing fan speed and temperature

my temperatures and fan speeds are slowly getting higher and louder on my imac g5 2nd gen (17", w/isight, 1.9ghz). i've never noticed my fans before. the only time i ever used to notice my imac made any noise at all was in the dead of night when i shut it down and noticed the absence of noise. but a couple of months ago i started being able to hear the fans when i play world of warcraft. since then, they have slowly gotten louder and louder, and they allow my cpu temp to get higher and higher before it stops rising.
before i could hear the fans i never noticed the temp, but after i started hearing them, my cpu temp usually maxed out at around 148º. now it is allowed to get to 167º and stay there while i play wow. and the fans are so loud i have to use headphones to be able to hear the game. simply surfing the internet now causes higher temperatures and fan speeds than playing WoW did a month ago.
should i take it to a service technician to see if anything is wrong with it?

Have you ever cleaned you machine? Since it's an iSight (which is actually 3rd generation, Ambient Light is the 2nd, Rev A the 1st), you can't open it but you can vacuum the air vents, which might help.

How to increase Fan speed | HP Travelmate 8510p

Hi everybody,
I post here because I have an issue that last from more than year with the temperature of my CPU. It's always near 50/60 when I'm lucky, and it can go to 90 degree and make the laptop crash when I'm running costly applications (like compiling stuff or playing games).
I would like to force the fan to run faster, like it was when I was running windows on the same laptop, so that the CPU (and also at the same time the keyboard which is burning my fingers) stay cooler.
Here is a sensors I just made :
DeepThought# sensors
radeon-pci-0100
Adapter: PCI adapter
temp1: +39.0°C
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +61.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +63.0°C (high = +105.0°C, crit = +105.0°C)
So it's seams the issue is realy the cooling of the CPU.
I tried stuff described here : https://wiki.archlinux.org/index.php/fan_speed_control but it seams I havent any PWM control on my laptop, or otherwise some drivers are missing :
DeepThought# pwmconfig
# pwmconfig revision 6166 (2013-05-01)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed
So if you have any advice, any method to try, I'll be happy to hear about it
Thanks,

The output is empty (nothing found).
> - Disassemble the laptop and replace the old thermal pads / thermic paste with new thermic paste. In my experience, this has yielded outstanding results.
I did it and it helped a bit, but doesn't solve the problem, and don't last long.
Pretty strange that I cannot force the fan to run at the highest speed.
> - Use a scaling governor to prevent the cpu from scaling to it's highest frequency
I may try that.

Increased fan speed after Leopard install

Hey - Just installed leopard today on my intel core 2 duo blackbook, and I have noticed that where under no processor load my fans would run at about 1800 RPM. Now, it has been consistently at about 2600. I have reset the SMC (I think that's what it's called, the PMU on PowerPC systems) and updated to 10.5.1. Has anyone else experienced this??
Thanks,
Dave

Spotlight may still be indexing the hard drive.

Unlocked bios + increased fan speed on GX740?

Hey there, I were wondering if the BIOS and EC version is up to date on my GX740 MS-1727
Bios:
E1712IMS.10F
EC:
1717EMS1.406
And if there is a possiblity to get my fanspeed turned up by 5% or somewhat?
etc. a unlocked bios could be awesome..
Thanks in advance.

Yes, they up to date
About the rest things, check PM for further queires

Mac pro 3,1 default fan speed?

Hey guys, ive been messing around with SMC fan Controller over the years, and have increased minimum fan speeds due to hotter ambient room temps, or simply because i was running extended cpu intensive activities. Good to take precaution since the 3,1s are known for increasing fan speed after things have already gotten too hot. This can lead to overheating. At some point within the SMC fan Controller app, i changed the "default" fan choice higher instead of creating a new blank custom fan setting before choosing my fan speeds. My problem now is that i dont know what the default settings were. i think one was 500, 600, 600, 800 RPM maybe? No idea.
its is a 8 core 3.2 earl 2008 3,1 Mac Pro Desktop. This has different fans than all other mac pros so this question is 3,1 specific.
I think the four fans are labeled:
Power supply
I/O
CPU
Intake
not entirely sure because i am away from teh computer at the moment.
Thanks

smcFanControl's preferences are located in /Users/<user>/Library/Preferences as com.eidac.smcFanControl2.plist. I believe that if you move that to the desktop and restart, a default plist will be rebuilt for your particular Mac. If that doesn't fix it, you can always put the plist back where it was.
Or, you can simply make smcFanControl not a startup item and then use something like iStatPro to see what the unadjusted fan speeds are because smcFanControl doesn't change the built-in speed defaults, it just overrides them as the lowest fan speeds.

C220 M3 Fan speed

Hi all,
We have our new C220v2 M3 server in our LAB rack and we can hear the fans constantly going from about 10% to 40% RPM.
Any ideas what's happening?
There is no load on the box and it's constantly doing this.
Josh

Can you clarify which fans are constantly running? Case/chassis fans or PSU fans? Reason I am asking is that I have a TAC case open right now for PSU fans running abnormally higher than they should even at low temperatures, while the case fans run quietly (as expected). So if you are seeing the same behaviour as me I would be very very interested to know.
You may also find that the case fans tend to rev up a lot once the Front Panel temperature sensor gets to 30 degrees Celsius. So even if the rest of the case is cool the case fans will start to really speed up once the ambient temperature at that location goes past that magic threshold. There are other factors and sensors as well that trigger increased fan speeds.
But anyway like Kenny has suggested we really need a show tech to know what temperatures your server is recording and what speeds the fans are running to know if it's normal or not.

Portege M400 freezes, screen goes black and fan speed increase when moved

Can someone please help me?
I recently received the Portege M400 from a friend 4 days ago and reformatted to Windows XP Tablet edition.
All was going well until I wanted to move the laptop to my coffee table, but as soon as I move the laptop it freezes, the screen goes black and the fan speed increases dramatically!,
So far I have had no success in fixing this problem and I much appreciated is some one could help me!

Hi there,
I have the same laptop. Bought it from a friend also! That was a year ago. It was working perfectly till 6 months ago when I had it going 100% like yours. Screen freezes, fan speeds up and hangs up once it is moved. Recently, even if it doesnt move it hangs up also. I have tried many things like reinstalling drivers and Windows.....etc.
I dont think it is Windows problem or drivers problem, because if you run BIOS and try to move the laptop, it also hangs up!!
Tried updating the BIOS, also no benefit. I ended up opening the laptop and having a look to the motherboard (thinking that I could see something that I could fix!! But again, did not get any results.
I tried also disconnecting peripherals one by one to see whether I could spot the problem, I disconnected the battery, the hard disk, the optical drive, the wirelss modem (from inside), memory, and even the bluetooth, but could not spot the culprit.
I believe now that the problem is basically the motherboard (sort of wear and tear insulation problem) and it is beyond my humble expertise.
I am sure if I would contact TOSHIBA, they would not be of much benefit as I am a second hand user. And if I try to buy from them a main board, they will charge me hell of money.
I hope that this is helpful for you to avoid you wasting your time like me.
Please if you would come into any progress, let me know. Likewise, I would be happy to update you.

MB990 and SL - Fan speed is not increasing automatically

Hi Guys,
Two days ago I changed my macbook's hard drive to a bigger one and did a fresh install of Snow Leopard.
As soon as I installed the SL I noticed my computer was running hotter than the previous installation. Without doing anything, my macbook is reaching 75C (167F).. I have already checked the activity monitor and no process is using the CPU. Now I realized that the fan speed is not increasing automatically, it is always fixed at 2000rpm even if the temperature reaches 72C.. I have already tried a SMC reset but the problem persists..
Does anyone know a solution for this? The problem is the fan speed that is not increasing..
I'm having to use smcFanControl to control de fan speed manually. Before the fresh install I was using Snow Leopard updated from the Leopard and I was not facing this problem.
Thanks a lot!

Hi there... i have the same problem. my temperature gets up to 75C with just one window open in safari or google chrome. I have downloaded smc Fancontrol but ...its not enough. have u solved this problem yet? i'm going in to the Genius Bar tomorrow to see if they can help.

CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,
I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.
Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.
I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:
[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +60.0°C (crit = +100.0°C)
temp2: +59.0°C (crit = +100.0°C)
temp3: +66.0°C (crit = +100.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +58.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +58.0°C (high = +105.0°C, crit = +105.0°C)
Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.
Here is the main problem:
1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.
2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

The fan was bad. I had to replace the fan. However, I have not been able to figure out how to see fan speed in sensors.

Do more HDs increase minimum fan speed?

While browsing around here I've noticed that a lot of people have a HD/Expan.. fan speed of around 500 and about the same for the power supply.
My readings are always higher (even right after switching it on when all temps are still really low): My HD/Expan fan speed is never below 800, and the PSU seems to have a minimum of 600.
I believe the reason for this may be that I have populated all four HD bays. Can somebody confirm that this would result in higher minimum default settings in Leopard?
Also, I wonder if there's a way to 'switch some HDs off'. While in OS X I only actively use two drives on a regular basis. The third one is used for TimeMachine and the fourth one is hardly ever accessed since it's my Bootcamp drive.
Any ideas how I can lower the fan speed (and hence the noise level)?

Thanks to both of you.
I realize that more drives emit more heat; what surprised me is that even while they are still cool (30C) the fan is already up at 800rpm - where it stays even when the drives' temperature increase. That is why it appears the 800 rpm seems to be a minimum. I guess to really find out the correlation number of drive/rpm I need to remove some drives.
As for the graphic card, I have an ATI 2600 which I cleaned thoroughly yesterday after reading about the ATI 1900. Yet, not much dust at all (actually I was surprised on how little dust I found in my Mac...seen a lot worse in previously owned PCs).
Thanks for your input guys, if anyone knows something about the original question, please feel free to come forward.
