yes, but i think this will not occur if you like me, had the i5+M295X. In those pictures is about the i5+580 and not the i7
Got a tip for us?

I had the same thing happen on my i5 + m295x. At the end it got so bad that the GPU would get up to 110c under a load and put the computer to sleep. It didn't matter what CPU you had that GPU just ran so damn hot.
you had? so you mean you no longer have this issues? you replace your imac or you did something?
Even though the fan spins up a lot it usually keeps the GPU at around 95W and it runs perfectly fine. It can go to 105 in some cases, but most of the time it's at 95 or less. And the fan only goes above 2700 when both GPU and CPU are being stressed at the same time
Some M295X have temp issues, over the years I've seen basically two M295X, one with max temps of around 100/101 degrees C (with lower fan RPM, and no throttling) and others with higher temp max above 105C and consequently maxed out fan rpms, we still don't knows the cause of the issue, fortunately I'm a lucky owner of the first one.
I had in I HAD a iMac with the m295x that had the same issue. I recently sold it.
This is not the case. The GPU was the problem I could be using all CPU and no GPU and the temps would never get very high, I could then use the GPU and not the CPU for something and it would peg the fan at max the GPU temp would get to 109c and the iMac would go to sleep. It really has nothing to do with the CPU. The m295x was just a stupid hot running GPU and some ran a lot hotter. I had one of the first ones.
I wasn't talking about your experiences, but my own. My iMac still works perfectly fine, and is among the first ones out too. Bought it about 3 weeks after they became available for ordering
based on the data i already had by that time and based on the data form previous generations of ati cards(2011)
you have to undersnatd that there are a LOT of conditions that can make every case different.
Just becasue you dont have any problems (yet or might never have because your house is less dusty and you live in less hotter area and you stress it less etc) it doesn mean that others are just deliberately making things up. The issu is calculated by a bigger data then one person experience. AS of today i can say that 295x is having the same fate as 2011 imac with 6970 ati card
I wasn't necessarily trying to claim that I was in any way representative of a data set at large. I was just curious as to how you could predict data for the future
. Regarding dust, I do keep everything quite clean, with no pets, etc. but I do stress it loads, with games, Final Cut, code compiling, etc. Though I also live in Denmark, which on average isn't exactly the hottest place on the planet.

Also becasue ATi havent changed . THey still make crappy unreliable GPU's in the mobile segment. And they still have the WOrst drivers support for their products( i mean look at the ridiculously outdated bootcamp drivers for ati cards on imac)
So was the conclusion that the 2014 5K w/ M290X is unable to play VP9 4K60 Youtube videos without stuttering?

I don’t know the M290X but my M295X is still rocking with video production 4K 50p in FCPX, super smooth even in reproduction, and after 5Y nothing has burned

Praise yourself lucky. Mine died. First GPU just started overheating regularly to the point of automatic system safety shutdowns, then died entirely. I've been relying only on my laptop for a while now waiting for the next model
My i7/290x model boots fine but in MacOS mode (not boot camp mode) it runs at a crawl. Something is really wrong and I can't quite figure it out. It's like it's throttled to run like a 10 year old computer. My wife's i7 9 year old model runs faster than it now. I'll have to remove all third party hardware devices to have a hope of figuring out what on earth is happening.
hello... what exactly did you mean when you died? ı am using the same device:/
Your quote of my message appears to be in another language. Are you reading MacRumours with a translator? The message as I wrote it was in English, but what appears in your quote is not.
In any case, it is a long time ago now, but my M295X iMac had a GPU failure after overheating. Would regularly hit 110°C on the GPU and the iMac's fan would spin to 3600RPM which is well above the usual limit of 2700RPM. - I may simply have been unlucky though. My replacement 5700XT iMac runs very nicely
