    Good day to all.
    I use the MBA in 2011, and sometimes have to work with Photoshop 5 and other "big" products. Sometimes, when my MBA is loaded - it is heated to 70 degrees Celsius. The same happens when playing Heroes 3 in the Vine

    As you increase your productivity?

    I know that you can not replace the memory for a larger volume, so you have to think about the reduction of

    That's quite normal.
    The rest of your post doesn't make sense. Please clarify.

    Its not the memory that's causing the spike in the heat but processing and/or GPU overhead. There's little you can do for those intensive apps.

    Anyways 70c is not that bad, my MBP approaches that when doing intensive work and the fans ramp up as needed.

    Do you mean RAM or HDD capacity?
    "Memory" is not the same as "hard drive capacity":
    It is recommended, to have 10 to 20 % of the HDD's capacity unused.

    the guide includes:

    Sorry for incorrectly. I mean the RAM.
    HDD - I quite enough.

    if necessary, I use smsFanControl to lower the temperature CPU.

    smcFanControl doesn't lower the CPU temps. It simply raises the minimum fan speed. You don't need any 3rd party app to manage your fans, as your Mac will manage them quite well without your interference. Your temps are quite normal.

    But tell me, the end of RAM - is 100 mb. What should I do? use swap?

    No, you can't add RAM to your MacBook Air, but that has nothing to do with temperatures or fans.

    Open Activity Monitor and select All Processes and then sort by Real Mem to show you the process(es) using up your RAM.


    Do you mean your SWAP file or your PAGE OUTS?
    Can you be more clear?

    ----------

    Yep, I was mistaken. I completely overlooked the AIR part.
    Maybe sell or return your Mac and get one with more RAM, if you use that much RAM.
    Open Activity Monitor and select All Processes and then sort by Real Mem to show you the process(es) using up your RAM.

    I just thought that if there is more memory, applications will use less resources and the processor will be less warm

    ----------

    Sorry for my English, I'm from Russia and English i know no much.


    I just want to improve performance or reduce the resources consumed by the system

    That is not the case. RAM and CPU are temperature independent, and just because some application uses more RAM, does not mean it needs more CPU power.

    As simsaladimbamba said, that's not always true.

    thanks for the clarification!

    I use just swap.

    What is a memory page?

    I heard that they can be placed on the MICs for most proizvoditelsti
    is it true?

    You don't have to do anything about swapping or memory management. Mac OS X does that automatically.

    That doesn't make sense, but you don't have to think about swap or memory management.

    Try UltraFan this is developed by one of the forum members and does help to reduce temperature under moderate load.

    Elevating the MacBook will also have a positive on temperatures I use Rain Design`s Mstand or iLap, however you can easily improvise. 70C is not too hot for a Mac as previously said, my own MacBoook Pro`s can easily reach 90C and greater with no ill effect.

    You don't need to. Let your Mac manage itself. Using purge can reduce performance. Don't do it.

    Dont worry about memory usage it`s not related to temperature and OS X manages memory extremely efficiently. I understand you logic in fewer proceses reducing CPU load best you can really do is to close all applications that are not required.

    Data held in RAM will actually help to speed up your machine, reduce HD access and CPU load, by purging the memory you will only have the opposite effect admittedly very minor. Purge will not have a positive effect on the temperature of your system.
