Q: MacBook Pro Retina Fan Issues

Had a mid 2012 rMBP 16gb. Traded it in because of the refresh.

Bought the early 2013 rMBP 8gb. Same issue as everyone here. My fan kept going off at odd times, even when all I was running was MS Words, and safari. It would last for about 15-30 seconds.

Brought it into the Apple store today and the tech ran through all the tests and nothing showed up. They wanted to keep the machine to make sure it's a hardware issue, I refused cause I need my laptop so I told them I'll just trade it in for a new one (still in my 14 days period)

Came home, set it up and now I'm experiencing the same issue. Fan is going off again. This happen every 30 minutes ish.

At first I thought it has to do with the ram. I had 16gb on the other machine and didn't hear the fan once. This machine chews up almost 7gb of ram with just normal processing (no photoshop, no editing, no flash, etc...) Anyone else think this may be the cause?

And maybe the shareholders would also like to know about this?

In fact I have the same issue here. But there's no performance issue. This rMBP 2013 is so fast, I would not give it back. I am pretty sure it will be solved with a new firmware update.

Could someone with a developler account test it with the new beta version?

Downloading right now. But I think we are more waiting for a SMC update rahther a OSX Update.

From this thread here:

There's a strong case that the fan spikes are caused by the new SSDs in the 2013 batch. If that's the case, doesn't this mean it's a hardware issue? And as jpad1208 said, if this is a software issue, we're all screwed...

Yep, but it can be the software/hardware combination! because the fans are needed for cooling and if you're device isn't hot, it don't need to cool, so there is a bug in the controller software (SMC).

There is a smc update in the update (reboot is required). It's in the article...

Just runned a Apple LossLess song and didn't have the fan spkies... for now.

Will run more tests.

Hmmm, interesting !!!

I don't see the mention about the SMC update...

Sorry guys. I'm running the last build of the 10.8.3 and despite I just said, with more tests I still have the fan spikes.

That's not very nice, but since I've the 2.3 model exchanged for the 2.4 model I've less spikes, but only when playing a apple lossless file.

Did you try to use an "external" software fan controller. I tried smcFanControl and had no fan spikes. It seems to be a workaround, isn't it.

No, it's not, it's just i Minimum fan speed, so if I set it to 4000 RPM it stil goes to 6000 RPM.
