When apple fix finally the heat issue realted to low speed fan when run vista or xp under macs?

Now i have new imac core 2 sio 20" 2.4ghz, the temperature its amazing high !!

I think the computer can be damged!!!

:mad: "#@#@|#|@#@||@ APPLE !! fix this #@#@# problem !!
 
I use few metters software and temperature of HD is 63 !!!
SZimilar results on vista and xp
If youput the hand over the top corner of the machien and under the back black cover you can feel the temperature its amazing high......
The fans runing very low........

I tested this in 2 imacs 20" 2.4ghz aluminium new model, same result, why if all its runing very high temperature i never listen the fans and you can detect the air come from machine, its not high flow !

If run under paralles , using osx you can listen fans in some moments runing at high speed, and amchien never have that high temprature you can fell touching the machine........but under windows never listen the funs at high speed.......


:mad:
 
Everybody's iMac gets hot to the touch.

In my opinion you're worrying over nothing. It's not the problem you make it out to be - so what if the CPU is 63C? It'll be fine.
 
Unless the CPU temp is running over 80C, its not too high. The iMac can *feel* hot because its made of aluminum which is an excellent heat conductor. Now when you say the HD temp is 63, do you mean the hard disk is running at 63C? What metering software are you using? Under OSX I would recommend iStat Pro.
 
Even as flopticalcube knows, my temps are abnormally high. And I have never seen my HD that high in temp, and I just got back from another 4 hour session of Americas Army in XP.

Definitely check iStat. I have found all the XP solutions to be highly inaccurate.
 
Ok i mistake for make this complaint.

I installed on this Imac the vista sp1 beta:
Windows Vista Service Pack 1 x86 Build 6001.16659 Beta 1

Now the hard disk temperature is 46C
The hard disk before thsi change is 53C not 63 just bad typo, i stay a little upset when write the post.

ANyway i continue detecting very high temperature of complete case, i think apple have improved the fan speed only for osx, and xp or vista need a little tweak for work at low temps.

Anyway the SP1 make a big diference, so part of the reponsabilility its only from VISTA OS.... sorry apple :)

The system really work great now, i see lot of bugs fixed, lvista is on good way with this future SP1 :D

The sp1 is under beta, and the copy i installed its downloaded form torrent, i somebody want test make under the risk of this sp1 is beta and no officially launched for everybody !!

Best regards.
 
This is not to flame anyone but too many people make up rules for Apple saying that since the iMac can run Windows that Apple is suppose to support it to run well on the Mac. NOT TRUE!. Macintosh computers are intended to run the Mac OS system and it's not Apple's responsibility to make sure the fans run cool while in Windows running Bootcamp.
The concept of running Windows on the Mac is to bridge gaps for software between both OS's so people switching to the Mac OS will have a seamless switch. Apple's not going to support Windows past the necessary drivers just so you can ditch the Mac OS.
 
Windows XP~HEAT~

Yes, I do agree that the mac gets noticeably hotter. I am slightly worried and do not use Bootcamp-Windows XP to play games(Assasins Creed/COD4) for too long for fear of damage of my system. I do not know the exact temperatures it is running at but....outside standard temperature is around 26C and 30C on hotter days and my Alu. iMac is significantly hotter than the room temperature.

Running OS X Leopard runs fine all day, and it will get borderline hot. However this is not so for Bootcamp-Windows for some reason.

Just out of interest; What buttons when pressed together on my keyboard will give me the apple:)apple:) sign?

I don't see anybody making up rules. I have no idea if he's got a real heat problem or not, but bootcamp is out of beta. It's an Apple product. So yes, Apple computers are made, by Apple, to run the Windows OS. Unless this is a figment of my imagination, if your Apple computer is damaged by a buggy bootcamp, then it's Apple's fault.
 
Software drivers fine tune the fans but the EFI will step in if the temperature becomes too high.

Sigh, sometimes I just have to shake my head. The basic problem is that the CPUs are not being used in any form of low power mode. They are being used as generic X86s. This means they are running SIGNIFIGANTLY warmer than they do in OS X. The same basic concept happens when you run a game or other CPU intensive application. The CPU cannot use any of its tricks to cool down, so it warms up. Is it dangerous? Running Warcraft makes my Macbook burning hot to the touch, but they are made to handle these high temps. For it to damage anything, it has to get REALLY hot. 140 degrees F is a walk in the park to electronics. If it gets hot enough to damage, the firmware steps in and turn the machine off. So, no, Windows will not melt anything and the fans work just fine.

THEY ARE NOT OS CONTROLLED!

Could you imagine what would happen if lets say something really strange happened, like windows locked up on a laptop. When was the last time we had thousand of laptops burting into flames? Lets think people before we speak.

Agreed.So what you are saying is that because the CPU is almost maxed out performing all of these other tasks, it does not have the capacity/time to control lower level functions such as the increase of the fan speed in Windows mode to run at a cooler level?

My main concern is not that my Mac will have a meltdown before my eyes. It is just that usually for instance, when a mechanical engine such as a car runs too hot(i'm not too sure what that would be for a mac) for too long, something gives way and blows. I might imagine a similar result for a computer but obviously on a smaller scale. However the point is, that there may be an inefficiency somewhere along the lines which could be fixed. Mabye there is software we can download to increase fan speeds on Windows?
 
Tools

OKay, I got some tools and managed to get some readings for what I am talking about, here they are:

(*Done using Temperature Monitor) and matched in iStat Pro.

Ambient air: 30.0˚C
CPU A Heatsink: 51.0˚
Graphics Processor Chip 1: 64.0˚C
Graphics Heatsink 1: 63˚C
Grahics Processor Temperature D: 68.0˚C
Hard Drive Bay 1: 57.0˚C
Memory Controller: 53.0
Optical Drive: 49.0˚C
Power Supply Position 1: 78.0˚C (seen this in 80's region as well) :eek:
SMART Disk: 56.0˚C
Wireless Module: 51.0˚C

How hot is TOO hot and what do you think of these readings. Mind you, these are done while running Leopard and not yet into Windows games through Bootcamp. Those readings are yet to come
 
That's similar to my readings on my iMac. I suggest SMCFanControl which allows you to control the fans and they stay at the same speed in Bootcamp if your worried.

This shouldn't be too hot but if your playing games in bootcamp on your iMac GPU can very ocasionally overheat and crash.
 
This could be normal for Windows. Have you noticed PCs designed for windows including laptops typically have loud fans and thicker.

Can you place an external cooling system and apply it to your iMac. Keep it cool. I had to do that back in the Powermac G5 days because sometimes the fans would kick on high and the system would lock up during video encoding sessions. I used just a fan and applied it toward the front and it helped keep it cool during the hot summer in addition to keeping the air conditioner at around 72 degrees.
 
Fan_controller

Thanks for the great responses. I have just installed the latest version of SMCFanControl for Os X 10.4(Intel) and above found at: http://www.macupdate.com/info.php/id/23049 <<<<<and i am hoping it stays cooler as it seems to be (least the numbers dropped from the near 60's range)

Well, there does not seem to be much that I could do about the problem of it being hot around me, except try to relocate to a more ventilated area armed with a fan and SMCFanControl. AC's pull too much current and are hazardous to the environment.

The only real solution for the heat problem wold be for me to move to ALASKA, where my only concern would be where to find the nearest power supply. LOL!

Keep posting
 
The hard drive is the iMac's most heat-sensitive component,
and yours is running far too hot. See the following thread

Yep - Leon knows better than the multi billion dollar company in question and their team of product designers.
 
Forum member kunzie who wrote a Vista64+SP1 install guide here, recommends a program called Input Remapper to control the fans in Vista to keep the temps down.

Please post a link to ONE WORD on the subject from iBorg HQ in Cupertino.

Leon only claims to know:

- what Seagate and Western Digital engineers say -- about hard disk drives

- and what Google Labs says -- about an instrumented study of 100,000+ drives

- and what tomshardware.com says -- about actual temperature measurements

- uh, and Physics 101

OTOH, AlexisV knows exactly what a multi billion dollar company would say
(IF they were to say anything at all). AlexisV also knows that each and every
iMac works perfectly 100% of the time; thus, it's not possible that any iMac
temperature, no matter how extreme, could ever deviate from the precise
value that the infallible product team intended.

...everyone has to believe something. I believe I'll have a tasty homebrew.

Which is why they offer an extra-cost three-year warranty. :p

Thank you for the links. :cool:

Nobody's Mac ever got too hot and died from running OS X, Vista or XP.

That's what people keep losing sight of. Yes, there may be an occasional Mac with a bad "thermostat," but I've never heard of one, nor has anyone here reported heat-related damage. Yes, the case gets hot, but it IS aluminum, and, as someone pointed out, an excellent heat conductor.
 
Mine cooks too..

27" quadcore i7... under mac os, just gets warm.. on XP sp3, it COOKs.. like, computer crashes after about an hr of gaming (too hot to touch the back top).. I wish there was some way to control this too.. have to keep the ceiling fan blasting and the ac going!
