Would like to disable the fan on my macbook pro because I have installed a SSD

    When I first purchased my MacBook Pro 2.3 GHz Intel Core i7, I installed a SSD.
    The SSD does not require a fan and hence the fan doesn't come on (at idle or while utilizing programs).
    HOWEVER, for some reason, whenever I play Solitaire City (App Store Version 5.00 Written by Peter Wiseman) that I purchased directly from app store, the fan enables and will not shut off until I finish the game and re-start my computer!
    Can anyone guide me in disabling the fan completely (or at least for this individual application)? Like I said, this is the only program that the fan EVER turns ON to.
    Please help if you can...appreciate it! ;)

    The fan is always on. You cannot turn it completely off. Doing so would cause your machine to overheat. It spins faster because that one application is more CPU intensive and generates more heat. There are many other applications that will cause the fan to speed up as well.

    There is no fan for the HDD or SSD inside a MacBook Pro. If you have one fan, that fan is for the CPU, if you have two fans, one fan is for the CPU and the other for the dedicated GPU (15" and 17" MBP).
    If you fan is not idling (2,000 RPM) and spinning faster, then that is due to more heat, generated by the CPU or GPU due to more activity, which that Solitaire game probably causes.

    Open Activity Monitor and select All Processes and then sort by CPU to show you the process(es) slowing down your Mac or speeding up your fan(s) or causing more heat.

    Macbook Pro fan...

    Like I said, I installed a Solid State Drive that has NO moving parts. Therefore, the fan NEVER comes on.
    However, with this certain application (Solitaire City), the can for some reason turns on. There is still NO moving parts though.
    So, can I disable the fan...?

    The fan is spinning, because the HDD nor the SSD are the hot parts. The CPU and GPU are. Download iStat Pro (Dashboard widget) to see your fan (s) idling at 2,000 RPM when not doing CPU intensive stuff. Playing that game obviously is CPU intensive, thus the faster spinning fan(s).

    You do understand this, do you?

    The fan is always spinning. Always. The only time it doesn't, is when the machine is off. You cannot (cannot) have the machine one and not have the fan spinning. Power on = fan spin

    That's a seriously foolish idea. The fan is critical to maintaining temps in a safe operating range. What type of drive you have installed has very little bearing on heat. The CPU and GPU are the two primary furnaces. Leave your fans alone, unless you want to damage your Mac and void your warranty.

    The SSD has nothing to do with the fan, which is always on, spinning at a minimum of 2000 rpm.
    No. It would be foolish to try.


    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)

    If you're not already using it, iStat Pro (free) or iStat Menus ($16) will give you accurate readings of your temps and fan speeds, among other things.

    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level.

    If your fans are spinning up without increased heat, try resetting the SMC.
    (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)

    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.

    ...disabling the fan on my macbook pro

    Thanks for the advice guys, appreciate it.

    BTW, the reason I thought I didn't need the fan(s) is because my fan(s) never come on...at least I never hear them (dead quite). The only time I have EVER heard them is when I play that solitaire city. Perhaps I have failed to complete any "intensive operations" besides playin' that lame-ass game.

    Regardless, thanks for your responses guys...

    Just because you don't hear them doesn't mean they're not on. Use iStat Pro, as I suggested in my other post, to get accurate readings of your temps and fan speeds.

    I'm downloading it as we speak...I'll tell you what it says in a NY minute.

    Thanks...

    There is a program called SMC Fan Control for Linux that I used to quiet the fan on my netbook because it sounded like a jet taking off even when I was doing nothing. I heard there was a version for OSX but I was never inclined to use it.

    On my 15 in MBP, the fans are quiet when I walk up, but as soon as I start doing things they spin up. I have an app called istat menus (shareware I got with some promo bundle) and it puts my CPU temp on my menubar. The temp hovers in between 130 and 145 degrees f but when I hear the fans getting really loud, the cpu temp has climbed above 180 degrees f.

    I would NOT try to find ways of disabling your fan unless you just don't like your Macbook. :eek:

    GGJstudios,

    I downloaded iStat Pro and it says it's installed...but I have no idea where to find and/or access it???

    I tried to click on the logo and it states, "The iStat Pro widget is already installed. Would you like to replace it?"! Where do I find it?

    You open Dashboard, if you have Mac OS X 10.6 Snow Leopard and older, you can press the F4 key, if you have Mac OS X 10.7 Lion and newer, launch Dahsbord via Mission Control.

    Too many cooks, it is like a cockfight, only that Sid is not here.

    ...found it

    It was in my "widgets"...NOT dashboard...hence I had to click on plus sign in my widgets and that's where I found it!
    p.s. you're right, they are running...

    SSD's under a heavy load do warm up.

    Do your homework on how they work for more info.
