While I agree it is not acceptable....I fail to see how you being an electronic engineer (surely you mean electrical engineer :cool:) is relevant as you had no bearing/influence on the design of the chip or the computer.

Not saying that I am Tony Stark, just letting the OP know that in my opinion as a fairly tech savvy person... 105 degrees celcius is NOT OK.

and is DANGEROUS in my opinion.

you'd be suprised how many people with no background in electronics have no concept of what is or isn't acceptable.
 
Just got the Mac back... No changes were made, as noted in the job sheet form.

I've run the programs I use on a daily basis and found that the temps are still very high. Not acceptable at all. Time to call apple :(
 
I do believe yours is getting far too hot. After several hours of gaming mine maxes out below 90°C.

Even with trying the "yes > /dev/null" x4 it didn't go much over 90°C and when fans kicked in it went down to mid 70ish.
 
What even worse now is that the fans don't speed up, even at 104 degrees C... It's been turned on f0r 30 minutes and already at these temps. I'm dreading the Phone Call to Apple, basically because there ' service provider' told me it was not faulty, so Apple are bound to take their side :rolleyes:

DUDE that is INSANE... your machine is absolutely broken...


its @104c and the fans are stilling idleing at 2000rpm...

there is no way that Apple will tell you there is not an issue...

and that place you sent your machince needs to be reported to Apple as incompetent... I think everyone here will agree your machine is not normal and needs to be replaced...


Get on to them and go mental.

Just about to make the Phone call now. Should I ask to be transferred to a higher level of support, or just let the first rep. deal with me accordingly ?

I would be nice at first, but if they start trying to tell you that the fans being at IDLE speed while you CPU is sitting @ 104 DEGREES CELCIUS is normal ...

I would start to get pretty irritated.

1. They are WASTING your time - sending it to those clowns in that repair company (who need to have their license to repair apple gear revoked)

2. It's Dangerous to have that machine operating at that extreme temperature.


I'm pretty sure that if you start shouting about it being dangerous and how much money you've lost (due to it being accessed by INCOMPETANT people in a POINTLESS excercise)

you'll get a replacement... personally I would not stop until I was compensated for this fisaco.

I deal with companies like this all the time, do not STOP until you get satisfaction...

good luck buddy :)
 
On hold with customer relations, they wont give in. They want me to send it in for further inspection... the computer isn't getting better as proved above with the fans... Group 8 are time wasters

EDIT: The Customer relations rep. said the temps don't mean anything to him, so he's ringing me back once he has heard from head of technical ... the place where I have just being for the past 20 minutes.

I can't see this going anywhere other than Group 8's workshop but I'm not giving up!

Tell them further inspection is fine once they compensate you for lost time/not having your machine for work.

Temp's don't mean anything to him... that's great /s

surely he knows things at 100c are hot like his kettle when he boils water.

That's exactly what I told him. If I send it for further inspection and they do renew the thermal paste, who's to say the fans still don't kick in at 100C, or that it's still going to keep crashing ( apparently the heat may not be causing this )
 
Turns out they don't belive me. It's getting sent off again and i have to create a quicktime screen capture of how to use the Application :rolleyes:
 
Ask to speak with a supervisor before capitulating. Demand it, go higher up the food chain.

I did.

Applecare - Technical Representative > Second Level Technical > Technical Supervisor > Customer Relations > Second Level Technical ( after being put on hold and called back, I was on the phone for just over 2 hours )

I'm now creating a video to show the i****s at Group 8 that my Mac is very faulty, and showing them how to use ArchiCAD basically which is where the heat issues is focused ( note, it did work fine so it's not at all the program ). Apple know that the temps reached 110 degrees C and ignored it because the morons at Group 8 said it was acceptable according to ' Apple's own Tests '

I asked what would happen if the people at Group 8 don't see what I see they said they will take it from there ( hence my video to prove it ). They said that iStat Pro was not reliable or accurate enough for any further action, other than a second ' investigation'. I will also request a REPLACEMENT unit when they find the faults because both Apple AND Group 8 said it COULD be :

RAM not working properly, hence the crashes
CPU is hot, proven by group 8 under the stress tests max 107-110/111 C
Logic Board problems
I told Apple the fans now only go up to 2000rpm no matter what the temp is, so the fans could be at fault.
HD for the crashing and freezing issues.

My Mac is seriously messed up, I do not want a repair though it's what I'm only entitled to.

The Customer relations rep. spoke to 3 other members of staff to see if anything can be done ( replacement ? ) and they all said no because I can't prove the issues and the group 8 a geniuses and think that 110 degrees C IS acceptable.

I feel let down by Apple very much, but I understand where they are coming from, which is to believe the so-called service provider because I can't prove anything.

They also said that I can take it to an Apple store and show the ' Geniuses ' instore the issues, then they will update the report on the system. I would but I don't have the time or money to travel 100 miles away. ( Hence why I purchased it online )

I'm now going to be another week without a Mac :(.
 
I've just received a Call from Group 8. They wanted me to explain all the issues I'm experiencing, with screen shots of iStat Pro and videos of the software that makes the CPU heat up ( graphic intensive Programs )

Again, they said that 105 C is PERFECTLY NORMAL for these sort of Applications ( Photoshop and ArchiCAD ). They will try to reproduce the issues I'm having but they said that crashes are hard to reproduce, so I said that the freezing of the machine is somewhat random.

They will no doubt spent a week just observing the machine, then hopefully contact Apple and explain what will happen next. I'm pretty sure they won't give me a new one, kinda sad given that I'm having to send it in again, wasting my time, the cost of machine and the time period in which it's failing is very small bla bla bla....

Poor service IMHO
 
Then you have bad thermal paste connection with the heatsink. I had the same problem on my 17" uMBP when I did the thermal paste wrong. Just open it up and do it yourself.

Apple said this COULD be the issue, but Group 8 won't look at it until the temp's are higher or when the computer turns itself off. Apparantley the fail safe doesn't always ' happen ' between temps of 10-110 degrees C, and they didn't tell me why mine didn't shut down. I got the impression that unless the desk is about to catch fire, my Mac won't shut down :rolleyes:

Okay, at first I was sympathetic to your situation but you're really blowing this out of proportion.

First off. The temperature reading is the DIODE temperature, not the entire computer.

Secondly, it won't catch on fire. You know what will make laptops catch on fire? That's the battery. The battery has explosive material when things go wrong. That's what makes laptops catch on fire, not a CPU.

Thirdly, even with a bad connection, a 100+ deg C diode temperature CPU won't suddenly burst into flames. The heatsink will still draw heat away. You'll break the CPU first before burning down your house.

Lastly, the real failsafe is not in the CPU diode, it's in the motherboard/logic board SMC. That has a failsafe of 105 deg C, +/- 5 deg C. The actual CPU failsafe temperature is actually in the upper 130+ deg C ranges but at that point the CPU would've already died. Its just there to prevent the CPU to literally burn out but it doesn't mean it won't. The Tj temperature is the MAXIMUM SAFE OPERATING TEMPERATURE of 105 deg C according to Intel.

And if I was in your position, I rather do the work myself because time = money and you're being made to jump through hoops. It's time to stop jumping through them and actually have action.

Thanks for the info.

I'm been told different things by different people. Group 8 say that 110C is fine for a end user to experience. Apple's website says that 95C is too hot, macrumors is mixed info. I've not done anything wrong but when I try to have it fixed, neither party is willing to take me seriously when I say the computer is not at all performing correctly.

I'm not technical expert but given that water boils at 100C and my hands are touching Aluminium that has a contained temp of 106C I'm bound to feel a little annoyed. I know that I'm jumping through hoops/going around in circles but I'm not a technical expert. I'm using the ' service' that I paid for which is suppose to resolve my issues. Failing that, I will be on the phone again or emailing sjobs ( not that I want to or that it should go that far, don't start a war ! )

No way am I carrying out the work myself. I'd rather have the morons at Group 8 look at it, at least then Apple may sympathise with me when I say my problems are true and that it's taking them too long to fix it.

EDIT: When the CPU is 104 C, the heat-sink is around 75C, if that means anything.
