Q: Noisy fan on 2011 macbook pro

Hi I know i possibly have taken a sledge hammer to crack a nut, but the fan on my macbook (10.11.3) is very noisy last few months and seems to drain the battery really quickly.

 

I have upped the RAM to 16gb

put in a new ( ansanor) battery  and

changed to HD to a samsung SSD

 

but my macbook still seems to be working very hard to do anything

 

I have downloaded SMC  which shows temp of 86-94c and RPM of 6,200 roughly

 

Does anyone have any ideas of why my fan is working so hard, and draining my battery?

 

 

TIA

 

Wayne

MacBook Pro, Mac OS X (10.7.2)

Reset the SMC and the NVRAM:

If there is no change, open Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.  When the MBP  'gets noisy', post images of Activity Monitor and SMC fan control for review.

 

Also run the AHT as Grant Bennet-Alder suggests:

Ciao.

    If you install RAM that does not have Apple-approved temperature sensors, your Mac can no longer accurately determine RAM temperatures, and will run the fans at maximum.

     

    To test, re-install the old memory. If the fans are now well-behaved, that is the issue.

     

    The obvious solution, if this is your problem, is to install memory appropriate for your very fussy Macintosh computer.

     

    If the third-party battery does not cooperate correctly and report its temperature and other data, that will cause a similar problem.

    Hi Grant

     

    I have installed Crucial memory ( mac compatible)  and it was doing this noise and killing the battery life ( maybe 60-70 mins use) with the original Apple fitted RAM before I upgraded.

    If there is a bad sensor, Apple Hardware test will likely report that fact. Reported settings of near-zero or near a power-of-two are likely completely failed, or possibly disconnected.

    Probably in wrong order, but i'm unable to run Apple Hardware test ( restarting holding down the D button)

    I've reset the SMC and NVRAM as per instructions

    but my processor still gets to 92-95c within a minute of starting my imac. I've run activity monitor and attached a shot  - I guess launcd which takes all porcessing time and power is an OSX thing?

    In regards to the AHT, if you have an early 2011 MBP, use the disk with the AHT instructions written on it.  If you have a late 2011 MBP, try OPTION + D on boot.

     

    launchd is not an area that I am familiar with but this link may help:

     

    https://discussions.apple.com/thread/6616343?tstart=0

     

    You may also try a safe boot and see if there is any change:

    Hi Ogelthorpe

     

    Thank you for that. I rebooted in safemode and my macbook  was fine - I followed that link regarding launchd and I know you said its not any area your familiar with but I got these results back ( will also ask the author of that link/post you sent)Screen Shot 2016-08-26 at 07.57.10.png

     

    So it looks like Citrix is the problem ( unfortunately I need it to access work servers)  but going to "force quit" and closing citrix netscaler gateway doesnt now make any difference to the fan - could it still be trying to update/execute a program even if the application is shut?

     

    Thanks

    It may be that the fan speed problem is not related to Citrix.  If you run the AHT, that might offer a clue.
