Max Fan Speed on MBP

I have checked my max fan speed for my MBP at /sys/devices/platform/applesmc.768/fan1_max and the value is set at 5700. Shouldn't the max fan rpm be around 6200? I have tried changing the file as root but I still am denied from changing it. What can I do?

Max fan speed macbook (white) fine 2009

Does anyone know the maximum fan speed of my macbook? it is a Macbook white 13" : http://support.apple.com/kb/SP579it heats up quickly and I want to set the values of the fans to protect.

I've had my fans rev up to 6500+ rpms before when, partcilarly, rendering 3D images. No worries - when your MBP heats up, so will the fans spin faster. They won't just fly off or anything. I don't know if there really is a maximum fan speed - I've reached 6700rpms before with no problems.
Stop worrying! The fans are doing what they're supposed to do and will cause no damage to your computer...

R845-S80 lockup with max fan speed

I have Satellite R845-S80, and it locks up from time to time. It happens very randomly and not very often, but suddenly fan speed goes up and everything locks up. It happens when it's idle and sometimes while I was typing on MS word. Fan speed going up and lock up is not related with temperature of laptop either. I keep upgrading Bios whenever new one comes out to test if it solves problem, but it still does same thing. Technical support suggests sending the unit for repair, but I don't think they can duplicate the situation unless someone use the laptop for a week or two.
Does anybody have solution? Thanks

I would have you update the Bios to the latest version, 3.60. I saw nothing specific to the fan or fan speed. But on this computer, they have done 4 Bios upgrades in the last 6 months with a long list of issues being addressed. Again, not seeing anything specific to fans or fan speed, but it's where I'd start.
The fans are controlled by a thermostat on the system board. As the computer gets hotter, the thermostat raises the fan speed. Check you vents for dust, dirt, pet hair, etc. Blowing the dirt back in the computer works, but only for a short while. Best option with a dirty computer is have a tech open up the computer and vacuum out the dirt.

Max fan speed

Is running my fans at max speed using smcFan Control going to harm my laptop in any way? Is it dangerous?

My opinion is that it will not harm your computer in the short term.
But your fans will obviously wear out faster, and you may find yourself with a broken fan in a year or two.

Can't reach max (also with fancontrol) and min fan speed manually

I'm using fancontrol to control my fan's speed. One thing I noticed is that maximum fan speed is never reached even when temperatures exceed max limit.
If I set max temperature in /etc/fancontrol to 55 and restart fancontrol, 55+°C will cause fan to speed only at ~5800 RPM. If I set min temperature to 60, fans will completely stop. 'pwm_enable' is set to 1 when fancontrol is running.
Now if I stop fancontrol, fan will speed up to ~6460 RPM while 'pwm' is at 255 and 'pwm_enable' changed to 0. I can't change 'pwm' value at this point. If 'pwm' gets set to 0, fan will completely stop.
At this point fancontrol is still not running. If I set 'pwm_enable' to 1 and leave 'pwm' at 255, fan will slow down to ~5800 RPM. If I set 'pwm' to 0, fan will not slow down completely, but will instead slow down to ~2080 RPM.
What's interesting is that although fancontrol can't reach max fan speed, it can stop fan completely, while I can do neither manually.
Any idea how to enable at least max fan speed for fancontrol?

Temperature and Fan speed? screen freeze

I Have 2011 MacBook Pro 13inch . I was having the screen freeze issue from a hot graphics card it cpu that so many others have with this year macbook. After a night of playing videos (not realizing it was in loop) connected to my hd tv using thunderbolt. After the first one it happened a few more time after playing any video for a few minutes. Screen freeze with little pixelated boxes, yellow or blue. After some research I reset SMC and seems sit of fixed it. I am not running SMC FAN AND Temperature Monitor apps and my fans run about 2000 all the time. When I get hit it speeds up but not to much, seems on point. Except when I play hd videos the system get gets to 75-80c . I still have not had the freeze but that's because I have temperature monitor to launch SMC fan set at max fan speed when it get a to 80 d
Degrees C. I'm wondering if anyone knows the safe temp the 2011 MacBook Pro should be running at When playing hd video. I know it gets hotter when playing hd video by without SMC it seems my fans don't kick on to max speed untill the MacBook reached about 85-90c. Once the fans max it cools it right away. I know the fans are working cause I hear them but should the fans kick on faster before it gets to that hot if a temp. And is it safe to play hd movies of its running at about 80-85c?
Thank you for any information you might have on safe and average temp and fan speeds. If anyone has a macbook pro please let me know when your playing hd video for about a half hour or more how hot your cpu is showing.

Macs have established a reputation for being inferior game machines. PC's dominate that area and if that is a high priority, I always recommend a PC.

I doubt that you almost' fried' the logic board, but you may have approached thermal shutdown.
I also have a 2011 MBP and have run applications that are CPU/GPU intensive with no issues (the MBP certainly does heat up and gets very warm). I have never felt the need for a third party fan control.
If you wish to run games a lot, a cooling pad and a cool environment would help the situation.
Ciao.

560GTX TI HAWK fan speed?

So I just got a new 560GTX TI HAWK (Bios 70.24.11.00.00) not overclocked, and the bios switch on performance.
I was looking around in Afterburner and I noticed that when the fan speed is at 85% it runs at the full 4500rpm same as if it was at %100, so is the max the fans can go up to 85% or is there something wrong with my card?

I just checked mine and about the same, 4560 RPM and no difference between 85-100%. It appears then that max fan speed RPM is when it hits 85%.

Unlock Fan Speed

I have an HP ENVY 14 1111nr pc. It has an i5, 6Gb or RAM, and an ATI Mobility Radeon HD 5650 graphics card. I just want to know how you unlock the fan speed on this laptop. I know there is a way because I have friends at school that tell me its possible, but I just dont know how. Lately my pc has been running warm, and I want to be able to control the fan speed.

Thanks, already know my way around Afterburner though . Its limited to 80% max fan speed... thats the issue! I want to unlock the 100% fan speed.
I downloaded the newest GTX 580 BIOS from the MSI website, and modified it with NiBiTor. There are numerous articles on how to do, and flash the BIOS properly, with a google search.

NOrmal Temperature and Fan Speed of MacBook Pro 13

Hi,what`s the Normal Temperature and Fan speed of MBP 13 during idle and when browsing or something?...please help..

The notional idle speed for the fan is 2000 rpm. If you turn it on you'll get about that and a temp of about 36 degrees in a cool room if you don't do anything. Opening a browser over wireless and say streaming a TV programme from the BBC will push the fan up to over 3000 rpm and the temp up to 60 degrees or so. Fan will drop to about 2400 rpm and temp to 53 degrees with gentle browsing.
Or that's what I get with a 2.53GHz 4GB memory machine. I took the 250GB disk out as it was noisy and put in a 120GB one that came from a Mac Mini so that may use a bit less power. (And the 2GHz Mac Mini has a rock solid 1500 rpm fan and rarely gets hotter than about 65 degrees - this has similar components to the Macbook Pro and so shows what a slightly bigger air access can do I guess).
The fan is rather faster and more noticeable than I was expecting with the Macbook, but the most noise came from the Toshiba disk which has now been banished to an external enclosure.

Twin Frozr II GTX 580 Fan speed unlock

Hi all,
My GTX 580 appears to be over heating so i'd like to be able to flash the bios if possible, (any tips appreciated) with a modified file to unlock the 30-100% speed fan profile.
Any help appreciated.
Kind regards!

CPU fan speed on P45 Neo3FR

I just installed Coolermaster Gemini iis cpu cooler on my system. From the HW monitor, I found that the max fan speed was only 1867 rpm. A similar reading was found on the reading of DualCorecenter utility. I have put the CPU fan speed in the bios to maximum but no change. The support center of coolermaster has confirm that the fan is able to run up to 2000 rpm.
Does anyone have a suggestion?
My system is
mb: P45 Neo3FR pcb 1.0
bios 1.8
CPU : E8200
PSU : Antec pure power 430

I tried the options in the smartfan, but no response. The fan speed did not change. Actually, my problem was the cpu temperature is about 1-2 degrees higher than the stock cooling. So, I took of the fan, cleaned both CPU and cooler, applied the correct amount of thermal paste following your suggestion. Now, the CPU temperature is about 40 to 41 C during idle compare to 43 to 44 using stock cooler. The fan speed has increased to 1910 rpm.
I just wonder that the fan speed may not properly regulated by the bios. Do you think it is necessary to tell MSI support?

Ordinary fan speed with max load?

Hi all,
I did a search and couldn't find anything so I figured I'd start a new topic so I hope this hasn't been answered before.
First of all, I decided I wanted to start gaming on Win7 in boot camp (3.0) for the first time yesterday, so I installed and started up CounterStrike: Source, initially I was getting 70+fps on all levels, but after a while my framerate would suddenly drop to ~17fps, and the laptop felt very warm (and the fan didn't seem to be spinning much faster than the standard 2000rpm).. A few topics I found said that Windows doesn't seem to be able to control the fan speed and recommended installed smcFanControl (which I'm now using). First off, I was wondering if someone could confirm if this is true? (And is this the same with Vista/XP too?)
Second, I decided that if I were to set a fan speed in smcFanControl, that I would want to be sure that it is capable of removing the heat from the computer, so I decided to run a few tests to see what the standard spinning speed was when the computer was running at 100% (Both cores of the CPU), so I ran 'yes > /dev/null' twice in the command line (once for each core), and I realised that the fan on my MBP (I only have one since I have the 13") didn't really increase from the default 2000rpm until the temperature had reached the late 90˚'s C.
(Both temp and speed measured with iStat/smcFanControl)
I was wondering if this is standard for everyone else? (It seems a little late to just start increasing the fan speed; I'd assume that they'd increase with speed linearly as the temperature rose to keep the laptop at a constant temperature.). So, when does everybody else's fan suddenly kick in? (Mine kept a constant 97˚C afterwards and the fans were running at around 5400rpm - they didn't seem to reach the max 6200rpm that the fan is capable of in a 10min test.) - Although they did reach highs of as much as 101˚C.
When the laptop had cooled down (idling), I decided to run the test again, this time setting the minimum fan speed at 6200rpm and the laptop didn't seem to get much hotter than 85˚C. Surely it would be better if Apple had the fans running at max to keep the CPU temperature lower than 100˚C.. I mean, if my CPU got to 101˚C with the fans still at 5400rpm, when would they reach the max 6200rpm, considering that the CPU is only rated for a maximum temperature of 105˚C?
I'm not complaining, I love my MBP to bits and I think Apple have done a pretty good job designing them and OS X, but I do just wonder if there's either something wrong with mine (or is this the standard for everyone?), or if Apple should perhaps have the fans come on a little sooner to take away the excess heat.
Thanks everyone.

hi,
i made a post a few days ago and it looks like heat is a normal problem (as in it normally sails into the 'danger zone). have tried some of the other solutions but not having much luck ..

MBP Fan Speed/Temp and one extra problem.

My 17" MBP fan is almost constantly running at the max speed (6000 rpm). The temp is at 75 C as well. Since i'm in school the loud fan speed it very annoying and I would like to know if I have a problem with either my temp sensors, logic board or fans.
My other problem is that I get two error messages saying that a usb port is drawing too much power and will be deactivated. I have 3 usb ports my two left ones do not work and only my right one functions.
Any help would be great.
~ Justin

One thing to do is to run the extended version of the Apple Hardware Test and see if anything shows up in the form of an error code. If you get an error code with "SNS" in it, that would indicate that a thermal sensor is either not working or possibly not plugged in. If a sensor is not working, the fans will run all out by default.
Another thing to check is Activity Monitor for an out of control process which is hogging the CPU. Open Activity Monitor and select "All Processes" at the top and "CPU" on the bottom bar. Then peruse the CPU column for any process hat is running amok. If you find one, then highlight it and quit it and see if that takes care of the problem. Sometimes a printer process will hang up and hog the CPU, but it could actually be almost anything.
Regarding the USB ports, you can try to reset them. Power down and remove both the power adaptor and the battery for 15-20 minutes. Then power up again and see if they work. If your USB devices are drawing too much power from your USB ports, you may want to try a powered USB hub.
Good luck!

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?

Moved from the Creative Cloud to the Lightroom forum. They will be able to help you here.

What are the default fan speeds of a MBP Retina 15'?

My settings got a little out of control, and I don't really know what the default values were, so what kind of fan speed does your MBP have in idle conditions?
Thanks.

2000 rpm is the base line that the fans run. They can ramp up to 6000 under a heavy load.
smcFanControl does not let you set a minimum speed to a value below Apple's defaults.
