Will the fans speed up sooner on a MBP 13" vs a MBA?

Hi there, I am trying to find out which model can handle playing 720P video better when out it getting too hot cause the fans to speed up and become noise. Either the 2011 MBP 13" or 2010 MBA 13".
Thanks for any input

Thanks for the quick reply, I have always been a fan of microsoft until 2008 when it crashed twice in one month, then I quickly became a fan of Apple, I have not yet learned all of the in's and out's of OS X 10.6.8 as I had with Windows XP, with all of the constant maintenance I had to do on it, I had plenty of time to learn. I like the "turn it on and run with it" function of OS X, and in the three years I've had macs I've done very little maintenance to them. I say "macs" because thanks to apple's OS X reliability I can afford the time now to own more than one computer, I have 5, one for every member of the family and it's not a chore to have one any more, there's no way I could keep my sanity if everyone of my macs were windows computers. Anyway, I was just poking around on mine and noticed some stuff that didn't look "XP right" so I asked. The info on the hard drive was from the "right click" on the "Mac hard drive" icon and the "get info" tab, it shows actual 639.66 GB total capacity, 112.26 GB available, and 527.4 GB used and the activity monitor still shows VM size as 137.91 GB, I don't know why?.?.. My XP laptop shows only 4 GB of VM used after I set it at that amount from the varying amount it normally used. I was just comparing the two, which I should not have done... Thanks..
I truly understand about the time issue.
Get info HD space available should be correct, and does not include VM.
I do not know the mechanism that OS X uses for setting VM, but I agree that it seems odd to have it set for more than the available HD space. I suspect if it ever had to actually use that much VM, it would "realize" that and adjust it.

How do you change the fan speed (rpm)

On a mac, how do you change the fan speed to 7200 or something?

As was mentioned, installing smcFanControl will do this:
http://81.169.182.62/~eidac/software/page5/page5.html
However, as others have indicated, you should determine what the issue is. For starters, is your machine actually running hot? Have you run something to let you know what the actual temperatures are? Setting the fan at max speed will make your system noisy, will reduce the fan life, and significantly reduce your battery charge.

Satellite A100: looking for software to control the fan speed

Hi,
I'm looking for software to control/read out the fan speed of my laptop, because Power Saver does not seem to do anything. It does not seem to matter if i set the 'Cooling Method' to 'Battery Optimized' or 'Maximum Performance', or even the fixed CPU processing speed. I've (de)installed the Common Module & Power Saver a couple of times to no avail.
Also SpeedFan & NHC do not work.

Hi
Sorry but I do not agree with your opinion about Power saver utility. Do you really believe that Toshiba create tool like this for nothing? Just for info: power saver utility is not available with Vista OS and on this forum you can find topics where people really missing this nice and useful utility.
Anyway it is well known that many tools you can find on the internet have no much influence on notebook cooling fan speed. To be honest, something like that can be very dangerous because most users want to have silent notebooks and overheating issues are totally underestimated.
Can you please be a little bit more specific about your problem? Is your notebook too loud for you or is battery running time to short? Why you are not satisfied with this tool?

Can you adjust the fan speed? How?

I had an espiode the other day where the MacBook got so hot that it basically shut down. Can the fan be adjusted and how do I get to the area to adjust it? I am fairly new to the world of MacBooks and would appreciate the advice.

You can easily adjust the fan speed by using smcFanControl:
http://macupdate.com/info.php/id/23049
That said, it sounds a bit strange that the MacBook would run so hot. The fan should adjust itself to the CPU warmth. If that is not happening, I'd investigate whether the fan really works.

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.

About the rules (logic) between the fan speed and the temperatures?

Hello All,
Well, I've had a bad experience with my MBP last week: my motherboard busted and had to replace it... Expensive part to replace!
After thinking about the reasons why it failed, my attention has been directed toward a possible motherboard overheating, which might have damaged the motherboard.
I've installed the iStat Pro widget and regularly monitor temperatures displayed vs. fan speed. I do get a bit nervous when I see a 84 oC CPU temperature and idle (2000 rpm) fan speeds. My GPU temperature is also sometimes in that range.
My questions are:
1) does anybody know the rules (logic) between the various temperatures (CPU, CPU heatsink, GPU, GPU heatsink, enclosure, HD, etc.) and the fan speeds?
2) other than with the fews apps out there, is there a way to customize the rules? Is there a text file or a plist file somewhere where I can change the rules?
Thanks!

If your idle speeds are 2000 rpm, you have one of the original Core Duo MBPs. For me, I see fans on my 17" CD MBP speeding up once temps get into the upper 70s °C.
Apps like smcFanControl allow you to alter the setpoints. Note that some users who installed smcFanControl, then uninstalled it, report symptoms like yours - namely, the fans remain at idle no matter how hight the temps get, until a thermal shutdown is triggered (somewhere close to 100 °C).

What's wrong with the fan of my 15 inch retina mbp?

what's wrong with the fan of my 15 inch retina mbp,when i play a big game like Batman ,the fans are so quiet and keep around 2000rpm,but the temperature of cpu is up to 80 degrees.(by the way, i have reseted the SMC for many times,but it doesn't work)

80 degrees F or 80 degrees C?

TS1367 My PowerMac G5 will not start up. There is no startup chime, no display and the fans speed up and sound like and airplane after about 30 seconds. Can someone help?

I push the power button, and it turns on, but there is no startup chime, no video display, and after 30 seconds, the fans spin up. Any ideas?

G5 has these hardware issues:
-- bad capacitors on logic board
-- bad capacitors in power supply
-- badly soldered video chip
-- "There were several Mac models with flat panel displays that had bad displays.
     Most had serial numbers beginning with "W8"---the code for one specific factory.
     This affected PowerBooks as well. If that's the case, the rest of the computer
     is probably fine." by Allan Jones in

Do the fans speed up when running Apple Service Diagnostic?

When i run apple service diagnostic cd (2.5.8) the fans really speed up and don't slow down so after a few minutes i stop the testing, is this normal?. It seems like it is the rear fans that are going full speed, can't tell if any of the other fans are speeding up or not, i stop the testing after a few minutes as i don't know if this is normal or not and don't want to cause any damage.

Unless you bathe the computer in helium gas, I doubt if the fans will run faster than their designed speed even full bore.
The helium gas relates to a war story told by my motors and transformers prof "way back when" of a cooling fan in a nuclear facility where the atmosphere in the containment vessel was helium for whatever reason. The fan was powered by a universal motor which had nameplate voltage applied to it. The thing that limits the universal is turning resistance, and helium, being less dense in that environment, provided much less resistance to the fan blades, thus allowing the fan to overspeed and then disintegrate from the resulting centrifugal force. From that, I learned that interdisciplinary engineering teams really do need to talk to each other on a constant basis. Plus, I guess I learned a valuable lesson if I ever decided to build my backyard nuke.

[solved]Manually control the fan speed[/solved]

To enable fan control, the module parameter fan_control=1 must be given to thinkpad-acpi.
For example, in ArchLinux kernel 3.6.10, add the following to /etc/modules-load.d/thinkpad_acpi.conf: options thinkpad_acpi fan_control=1
Having done so, reboot and you can use the following commands to control fan speed:
# echo level 0 > /proc/acpi/ibm/fan (fan off)
# echo level 2 > /proc/acpi/ibm/fan (low speed)
# echo level 4 > /proc/acpi/ibm/fan (medium speed)
# echo level 7 > /proc/acpi/ibm/fan (maximum speed)
# echo level auto > /proc/acpi/ibm/fan (automatic - default)
# echo level disengaged > /proc/acpi/ibm/fan (disengaged)
If you receive a PERMISSION DENIED error you can use the following command syntax instead as a work-around:
# echo level 0 | sudo tee /proc/acpi/ibm/fan ##(fan off)
# echo level 2 | sudo tee /proc/acpi/ibm/fan ##(low speed)
# echo level 4 | sudo tee /proc/acpi/ibm/fan ##(medium speed)
# echo level 7 | sudo tee /proc/acpi/ibm/fan ##(maximum speed)
# echo level auto | sudo tee /proc/acpi/ibm/fan ##(automatic - default)
# echo level disengaged | sudo tee /proc/acpi/ibm/fan ##(disengaged)

Reset SMC.

HT201250 I have an iMac with 2 external hardrives. Will the G Speed Q set up these external hard drives

My iMac has two external hard drives. I have the G Speed Q for backup . Will this automatically back up these two external hard drives ?

Time Machine will not automatically backup external drives unless you remove them from the Exclude list. However, if the drives are disconnected, then you will need to reconfigure Time Machine once again not to exclude them.
Time Machine is intended mainly to backup internal drives to external drives, not to backup external drives to other external drives.

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?

My 2006 iMac has begun to run hot which often causes issues. How can I adjust the fan speed with supported software?

24-inch iMac (2006) funning hot. Used "power button while turning on" trick to cool it so we could load some software which was telling us it was too hot; it was also smellong like it was going to burn up on fire one day while running a slide show for an hour. Need to figure out how to un-do the constant-on fan and need to find "supported" software that allows me to vary speed.

There is one called smcFanControl 2.2.2 released, but you really need to make sure that your iMac's air intake vents are clean and free from dust so that it is not sucked deeper into the iMac.
To clean the iMac's intake vent:
1. Shutdown the iMac and disconnect everything from it including the power cord.
2. Lay the iMac face down on a soft towel or cloth and go get out the vacumm cleaner.
3. Usinge the vacumm's brush or cravass tool, vigrously vacumm the bottom grill and small vent under the stand.
4. You also might want to remove the center RAM cover on the bottom and carefully vacumm it out without distrubing the RAM modules.
Then next before using smcFanControl, use the iStat Pro, a Dashboard Widget by iSlayer to first check all the sensor temp's and the speed of all three fans.
Finally if it is still having a cooling problem or you find that a fans has failed, you should stop using the iMac until the problem is fixed by an Authorized Apple Service Provider.

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.
Check this!!!
