iMac Retina Temperatures?

[theBigD23]

What temps is your iMac running? My system seems a little hot where the fans have to kick in every once in a while. Fans always kick in when playing a video, flash or no flash. Temperature will stay a little high, but the fans will be about 1700rpm. My system temperature just using the system (not playing games or video) is between 140 and 151, depending on what I'm doing. Currently, I'm at 147 with the fans at 1200rpm.

I do have a lot of programs open at once, but they do not use much memory: twitter, mail, calendar, reminders, and two browsers.

I did see before that Retina iMac's run hotter. But are these temperatures consistent or too high?

If you use chrome as one of your browsers it's a good percentage responsible for most of the heat especially (it's well known power hog) especially if you have open pages with flash content (this is true for all browsers).

Also, please include your iMac's specs (cpu gpu and ram), it will be more convenient for people to help you.

Thanks, I mainly using Firefox and Safari.

I don't have Flash installed, it's just on Chrome if I need it.

I have a Core i7, 295x, 32GB RAM.

Those temps are standard for the 295x I believe.

I have iMac i5/m290x 24 GB and it my GPU runs 107F at idle and goes up to 122 F when watching a Youtube video 1080p for 3 mins. Fan is never at audible levels

Oh wow, I didn't know the 295x would add so much to the temps. Maybe I should have gone with the 290. I wonder if El Capitain will fix these issues and run the 295x more efficiently.

m295x runs very hot, for many users it tops at 102-105C (~220F) when pushed, and then it's starts throttling.
These temps are certainly not good for the longevity of the internals, but some people say that these GPUs have been manufactured with higher specs - thermal tolerance.

Anyway, I think that the longevity of these devices is absolutely a subjective case...

Please don't worry, have in mind that it's also summertime...

El capitan will improve the os x code so possibly there will be less stress in hardware, but I think that these GPU are by design built to run like this, so .... we will see.

Maybe if there was a way to down clock the m295x...

Thats a big reason why I went with the m290x. If you're making money from your iMac editing 4k movies obviously you are forced with the 295x but if you can help it you might want to downgrade if the computer is mostly for casual use.

I ordered it day 1, so I didn't know about this. Interesting though. Hopefully El Capitain will do what Xbox does, for example, where it uses less cores or power when it's not needed.
