It's not that I'm furious, I'm not furious. I would say disappointed is more the word I would use to describe how I'm feeling. Someone said a while back "Does apple test their hardware anymore?" That's kind of appropriate In my mind. But, the 2 and 3 battery wireless keyboards and the mac pros have been fixed all in the last two weeks so I'm optimistic about the imac's.
well fair enough then! that really would put enough doubt into your mind. i personally havent had ANY problems with any of my macs when they were new (sure with older ones problems do arise) - ive been using them for 20 years and my dad a good 5 years before that.
Since it's 1:30 am here let me give the quick version of what I know, bare with me m8 I'm exhausted. If I sound like yoda today I will try and clear myself up tomorrow so I make sense. What's happened so far and I'm only speaking for myself is this -
all good man i know exactly how you feel. its 1030pm here and i feel so tired! i donno why.. hope u have a good sleep
My processor gets very hot when I use anyone of the following:
Flash
Logic Studio
Garage Band
Itunes
VLC media player
could you possibly be more specific when you have the time?
playback/recording of logic studio/garage band would of course increase the temperatures, they can be quite intense applications at times.
flash is a no brainer.
itunes, well.. there could be a problem there, as with VLC, depends on what you play.
I've had temperatures up to 71C.
now this number is somewhat troubling, not too much though. as stated below my temps dont really go above 65°C. i wonder if you have a bad thermal paste job?
For instance, When I have a cpu heat sink temperature (determined by Hardware monitor and or istat pro) of 50C using anything but the aforementioned software (all audio) my fans run at around 600 to 700 rpm. I can stress the machine with photoshp (multiple filters rendering on hundreds of pictures at the same time) to heat the processor up for testing, it uses cpu resources that's about it.
my CPU according to iStat reads 50°C right now. it is idling. my ambient temperature is 26°C*, it is quite humid (75%).
optical fans: 999rpm
hdd fan: 1872rpm
CPU ran: 939rpm
stressing the machine by converting a 1080 mkv movie will result in the fans ramping up to around 2000/2500rpm for CPU and optical drive. the temperature does not raise above 65°C once the fans speed up.
When I use the aforementioned software and still at 50C (which doesn't take long or last long) my fans will be @ 1800+ rpm and my cpu is at 1% usage. I'm not sure how hot the cores need to get to shut of Hyperthreading, that's what I was looking into tonight when I got sidetracked in macrumors land. I do not know conclusively if I'm being affected in the deeply in the cpu department. Under the hood it feels like it especially when running a long recording take.
recording can be quite taxing, and i honestly do not blame the CPU/fans for ramping up in that scenario.
fwiw, i have been playing an .aiff audio file for the last 10minutes, my CPU temperature has gone down and my fans give identical readings to what they did before.
just to clarify:
- the MP audio problem had to do with the CoreAudio side of things, playing quicktime, itunes, VLC, flash, or ANYTHING that produces audio (FW sound cards, and even FW external HDDs when moving large amounts to data across drives) will cause the increase in temperatures.
- the fans on the MP do not increase at all. the users had to manually increase them.
- there were significant increases in power usage from the CPU. e.g. 5w (IIRC) up to ~80w just for the CPU. the total power supply went from 10's of w to 100's of w! (currently i am using 4.8w on CPUA, readout from iStat menus).
it would be great if you could record before/after scenarios for the above dot points i just mentioned, to give a better indication
That's what I feel know that's accurate for now. Apple is interested in hearing from me, they've been helpful but of course haven't said it was a known issue yet. I was at pro software as well as Level II support within 10 minutes of my first call. No ones even tried to blow me off, they truly seem interested. I'm hoping that's because they're in the know but can't say anything.
well i surely hope that you can get to the bottom of the problem! its highly disturbing to know that this problem may also be related to our precious iMacs!
Hey thanks for trying to help me us DoFoT9, I really appreciate it. What do you think and where do you think I should proceed from here?
no worries there mate, i enjoy troubleshooting and getting to the bottom of problems
no rush on the reply ill be around.
from here i think that you should maintain communications with apple, and try to get to the bottom of it. have a professional apple rep (not some crappy guy that says everythings normal, have them take in-depth diagnostics of the changes observed) take a look at it and publish the reviews here if needed.
