AMD Radeon R9 M295X Core Clock Throttling, Heat, and Performance

With El Capitan my temps has grown by 1 now @ 100 to 102 (sometimes) under full gpu load, before was 99/100 (sometimes 101) but I see a good performance improvement overall

And of course, no issue so far since last December running 24/7
 
I do some extensive video editing and screen capturing in Screenflow and I will hit 105 on both my CPU and GPU regularly under full load. The fan will spin up to 2900 rpm, and it is fairly loud. I only will run it this way for brief periods of time, maybe 30 minutes a day, but nonetheless, I push the machine to it's limits. General idle CPU temps are about 58, and GPU temps are 70, a bit too high I think.

Is the shuttering/lag for things like mission control gone or still there?
 
Never had it, and when I push gpu and cpu with Final Cut, even for an hour, I do have high fan speed, cpu is the one that push the fan to the limit
 
Just to add to this discussion, I have an i5-4690/m295x that was bought this past June. I just started gaming on it a few weeks ago (mostly some Far Cry 4 on Windows 7, sprinkled with a little Civ 5 on OS X), and had to take it in to the Apple Store a week and a half ago because the GPU burned itself out. I was assured by the technician at the store that this was just a faulty part, but judging by this thread, I might just be the first of many failures.

They replaced the logic board, assured me everything was good, and sent me on my way, but I'm now actively monitoring the machine's temperatures. I've been getting the same results everyone else has been seeing, ~105°C GPU temps within seconds of starting a game up. I'm going to continue gaming on it (I'll be damned if I spent that much money on a machine and can't get at least some gaming time out of it), and I'll let you all know if I manage to burn out a second card...

Sorry for your loss! Are you sure it was the GPU, though?
 
The cooling is just barely enough. We have several of these machines at work, if you start doing something that is computationally intensive the fans start whirring like jet engines on take off. My suspicion is that after 2-3 years they will just die, such high temperatures nullify the possibility that a computer can last for a long time.

For the record, previous generation iMacs have also met their fate the same way, so it's not like I'm talking out of my ass. They die after several years on the workplace without any exception. If you really want a mac don't buy an iMac, just go with the mac pro. Those things are reasonably well built and will last for a very long time.

I'm gaming a lot on my late 2013 27", and even if the nVidia GPU is a lot cooler than today AMD's, I push the fan at 2200rpm before launching a game, I think it will help to extend the life of my 780M.
I use Mac Fans Control on Windows or iStat Menus on OS X 🙂

Yeah, get AppleCare and find an Apple store in a nice mall. You'll be getting tight with those Genius bar folks.

105 C is WAY TOO HOT. At least it's thin.

you are not the first one unfortunately...and not the last one.. at least 50 burned cards went thru me because of heat issue(and my repair shop is not even that well known).Its worse then 2011 6900 series disaster...much much worse..I mean its been a year only and already so much faild cards.
Dont expect it to last at 105c (((

*Looks over at 2009 and 2012 iMacs that have run 24/7 since day-one purchases....*

Hey, I guess I found two exceptions, and that's just in my house!

Would anyone with a M295X please be so kind as to see if 4K60p playback is smooth with YouTube on Chrome? M290X is stuttering.

4k60 Videos

The first few videos I looked at weren't even 4K (didn't look at all of them), despite their description stating they are 4K, but they played fine at their max res of 1080p on my 5K iMac.
 
My 2009 i7 iMac has been running 24/7 for over 5 years as of last July it went to my wife and it's been running 24/7 since then.

My 5k i7 iMac that I bought in July at the same time has been going 24/7 as well. I've been watching the temperatures and the only temps that look askance are internal i7 temps that get within a few degrees of max safe operation. I'll be keeping a close eye on that one.
