Hi. Today, all the sudden, the fans of my rMBP have started to make a loud noise. I just installed Temperature Gauge from the Apple Store and this is what shows: I am just using MS Word and have the Firefox open; is this normal? I read of some people with issues on their rMBP fans but understood the issue was solved with the 10.8.3 upgrade, which I already have installed. Help will be appreciated. Thanks
You have way more open then just firefox and MS Word. The temperatures aren't too unusual, GPU 68 CPU 58 isn't too bad. I've found iTunes sometimes starts running things really hard for no reason.
Thanks!!!! I closed everything else that was open other than Firefox and Word and it normalized: Itunes was one of the open windows, so perhaps the issue was there just like you suggested.
If you even find it running hard, open Activity Monitor and look at each applications CPU and Memory usage, something might be hogging resources for many different reasons, one being it's an old version. Those temperatures look very normal though. Something does look a little unusual though possibly, I could be wrong but 3800rpm fan usage does seem high. I'm doing a few things and mine is around 2000. It depends on the temperature of the room and a bunch of other things though. However I don't know too much about why this would be happening. Maybe someone else does.
I seriously doubt there is any issue, there are multiple app`s open, potentially Flash, Nividia GPU may well also be engaged all this adds up thermally. So fans at +3K is not unreasonable.
Hi, just did the SMC reset, this is what shows now: It does shows lower fan speed and activity across the chart, so perhaps the reset did the trick! Thanks
I like the look of that app but it's 10$ just to read temperatures?! I thought it'd be like 2 bucks. Guess I'm sticking with iStat
Even after you did the SMC reset I think you're fans running quite high! 3000 rpm for 46 degrees celsius is quite a lot. My 2010 MBP is 61 degrees and fans are idle at 2000 rpm. Maybe you could post a screenshot of your activity monitor!
I'm betting he didn't take that screenshot at full idle. He probably took that screenshot right after winding down some process. At 46 degrees the fans will spin at 2000 rpm at idle.
