Q: Why does apple feel the need to limit fan usage on a LAPTOP?

The macbook pro for some reason waits until the thing is 65 degrees to even get the fan moving. Its bad enough they insist on using passive cooling through the aluminum cover WHICH SITS ON PEOPLES LAPS. Its obvious "artists" get final design decisions because I would love to talk to a computer engineer who thinks that their design (which has been used for years now) is practical for any user that does anything more then check email. It wouldn't be such a problem if the design worked well, but since it performs poorly all the laptops need to thermo-throttle there cpu's leaving your lap hot and your computer slower. Been enjoying my burnt lap since 2012. Thank you!

MacBook Pro, OS X El Capitan (10.11.2), null

    Ask Apple, (which is not us)

    How do you suggest I do that?

    The point that you are missing is that Apple has designed that the MBP NOT be used on a persons lap.  Please read this Apple support article:

     

    https://support.apple.com/en-us/HT202179

     

    The bottom of the MBP is a part of the cooling system and if it is on a persons lap, that is inhibiting the heat dissipation process.  There is nothing wrong with the design if you understand how the MBP is meant to be used.

     

    Ciao.

    Thats great.. And we all know how great of a thermal conductor wood is. So unless I use this thing on a metal table its just as worthless. Thanks for proving a point. That answers my question.

    I place my MBPs on 3/8" thick aluminum plates to aid in the heat dissipation process. It is a 'poor man's heat sink' but it works.

    The rubber feet stop that from working

     

    How much heat transfer is there through 4 little rubber patches

    Ahhhh, you fail to take into consideration that the plates do not come in contact with the entire bottom, but only the areas between those insulating rubber feet.  That allows for reductions of many Fahrenheits, Celsius' and Kelvins.

     

    As I write this, CPU temperature is 42°c.

     

    Ciao.

    MBP's work better when close to melt

    A few precisions:

    • The fan(s) operate(s) continuously. Not hearing doesn't mean not running. Minimum speed is 2000RPM at idle, going all the way to 6000RPM at full speed. 13" models have one, 15" models two. Use a utility such as Bjango's iStatMenus to check on internal temps and fan speeds.
    • No such thing as THE temperature. They have a multitude of sensors to measure and control internal temps. My current Retina has close to 20, older models with HDDs even more to monitor the drive itself (an extremely effective heating device, BTW).
    • In no Apple documentation are these devices referred to as laptops. Never meant to be used as laptops. Clear indication is made to use them on a hard surface with no loose obstructions.
    • Airflow is on the Retinas thru the side vents and out the back at the hinge, on the others in thru the center of the back hinge and out near the corners of the same. All documentation stresses that the bottom and sides be kept clear of obstructions impeding free airflow.
    • Enhanced cooling (on the hard surface) can be attained by lifting the portable to increase air motion. A number of pads are available, passive or with auxiliary fans. I use a CoolPad to great effect:

    I'll jump in and add to the already provided insightful and excellent responses, why would you want to have something running if it is not necessary? Conservation of energy is a good thing, especially when users are demanding battery power longevity. When driving do you want your engine running at 3000RPM when you are stopped at a stoplight? You surely don't want to waste gas when not needing to.

    My MBP's used to live onstage in racks, they got really hot (95 C+) never broke and ran fast.

     

    This is a non-problem
