iMac Running Very Hot- Need Advice

These are the temperatures for my iMac at this moment, I have mail, iChat, messenger:mac and Skitch open. What's going on?

That's not hot, it's well within acceptable temp ranges. My MB is in the 57C range right now, and that's actually cooler than it's been in a while (HDD swap). You're fine.

My Pentium 4 is at 68 right now. Low 50s is nathin. Also remember with a computer like the iMac, compromises in cooling have to be made in order to have such a pretty computer.

I was told that I shouldn't be getting temperatures over 50*C, generally about 43*C in my HDD, was that wrong?

[rfruth]

All-in-ones tend to run on the warm side but your well within the limits IMO

Nothing appears to be wrong to me, everything seems to be fine.

This is my temp. As you can see, you're not very far removed from this. This was after a few hours of playing a game in Win XP under VMWare Fusion. I did bump up the cpu fan in smcfan control a wee bit.

your temps are good nothing to worry......basically the cpus are ok for anything much in new imacs its just the hd temp to watch.....basically if hd is in 50-60 C for a long time that reduces the lifespan......just use smbfancontrol if worried or if u use gaming in bootcamp

basically if hd is in 50-60 C for a long time that reduces the lifespan

In theory! I know I won't be using my iMac in 4 years time. It will have been sold on ebay and upgraded to the latest one.

not sure what HD is in your iMac, but mine has a western digitial and on their website it says the operating temp goes up to 60 deg C I believe. With smcfancontrol mine usually sits at 48-50 deg C and occasionally get to 54 for short periods of time. I think an "avg temp" of 50 or below is fine for the HD.

Those temperatures look fine to me, mine are pretty similar:

Nothing to worry about.

Hot? You Intel users don't know the meaning!

I love my G5, it saves me money on heating bills :p

One is in Fahrenheit, the other one is in Celsius.
Not a fair comparison between the two. :rolleyes:;)

[Fonzijr1964]

yep

re post in C

[LukeHarrison]

did u c mine?

Ok, if you want to play those rules, here's mine in F.

Scorchio! :)

wow

[LukeHarrison]

Yeah, I know! I used to get really worried about how hot it got, but it's been working fine for three and a half years now, so I'm sure it's fine. I've never compared against any other iMac G5 owners though, so if you've got one, show us your temps! :)

Thanks!

No problem. I am glad that I can help. :)

On your iStat, you have CPU A and a temp.
On mine, I have two CPU A's listed for my iMac, with two different temps. Why is this? Why is one not CPU B? And why do you only have one showing?

Erk... too confusing for me :-(

[luffytubby]

How do I view the temp on a Imac?


When I touch on the top corners of my Imac 3 GHz, its very very hot... almost so hot its unbearable to hold... I am quite concerned.

Install a program which shows the temperatures using the inbuild temp sensors.
Istat is a good one. Just google it.

Oh btw guys. About the temps on iMac.

I would recommend at least to monitor the HDD temp and keep it under 50c.

My 6 month old 2.4GHz, 24" iMac's Western Digital hard disk head crashed and the whole disk died with the nice sound "tik, tik tik" ..i suspect it was due to the temperature which was about 54c idle. The mean time of hard disk failure sure correlates with temperature. For example, i have a more louder linux server which has proper cooling, and the disks are running 32c.

Good thing i had 1:1 backup of the whole disk, thanks to the Time Machine.

I was thinking already before the crash that it might be too hot, but i gave apple's designers the benefit of doubt.

I sure will be wiser in the future and speed the HDD fan a little bit from the default so it will keep under 50c ..that is, after i get my iMac back from the repair :rolleyes:

Completely normal.

It's one of those. Did it die because of the temperature or is it pure coincidence? Since the new iMac was released in August 2007, we should have started seeing a rash of hard drive failures become apparent in February/March/April if it was a fundamental design fault and this affected hard drive performance.

Hard drive failure tends to follow a U shaped curve. Most hard drives fail in the first few days of use. Then there's a couple of years of low failure rates before it rises again 3 or 4 years down the line.
