Has anyone else experienced issues with fans on an early 2013 MBP w/Retina?  I just bought one last week and when I'm just sitting there doing nothing the fans will speed up to 6000 rpm and stay there for about 30 seconds to 1 minute and then drop. This occurs at random times.  Sometimes 1-3 times in a day but sometimes 10. This does not seem normal to me if all I'm doing is sitting there using safari or whatever on yahoo.  I look at Activity Monitor and CPU will be a 95-98 % idle, with very little disk I/O.  I went in yesterday to exchange this computer to rule out a hardware issue since it's brand new and the same thing is happening again.  I have a case with apple and have reset SMC and other things they wanted me to do with no results.  I just wanted to see if anyone else has had better luck with there $2700 laptop? 

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)

    Almost everybody with the early 2013 MacBook Pro retina got this issue. It seems to have something to do with the Sandisk SSD. When you write a large amount of data to the disk, the fans spin to 6000 RPM for no real reason. There are quite some discussions about it around here. It should be possible for apple to fix this with an software/firmware update, so lets hope its released soon!

    As far as I believe, Blackmagic Disk Speed Test only writes small chunks of data and uses some calculation and predicition to 'meassure' the speed of the disk. It doesnt really write an large amount of data to the disk. But when you copy some large files, or install/update big software like Adobe, the fans will kick in after a few minutes. I can reproduce this every time with copying files, while the temperatures are just fine.


    As you say there is about no CPU and IO usage, what are the temperatures of your system? Is it actually running hot when the fans kick in, or they're just moving cold air? Unlikely, but there might be a air intake/temperature sensor issue with yours. Try copying some large files, if the fans don't kick it, its not IO related. Then we've canceled that out, and an that case I recommend visiting a genius, as it indicates something else is wrong with your machine.
