Poll: M295X GPU heat in Valley benchmark

What GPU heat did you get?

Update: talked to apple card support, he said the temperatures on 104 for GPU is not normal, also 100 for CPU is too much.

Left the computer at an Apple Store (well reseller store to be exact) We'll see.

It is normal. You're wasting your time.

Apple Care stated it is not. It would be wise to listen to them. We'll see.


Please let us know what the outcome is. I was told the same thing by AppleCare and was recommended to return it.

I received my refund yesterday.

Well, I guess I should eat my hat now :).

They ran every official Apple test under the sun and their conclusion is that it is within spec. Nothing has been changed.

Time to let this go and just enjoy my computer.

Wait, so Apple are telling you that the Retina iMac is supposed to force the M295X GPU to throttle under load?

Or does yours never reach throttling temps (105°C)?

He was at 100/101°C as per one of his last reply (go back 1 page), so perfectly normal and on spec.

And at the time of the thread start he was at 104°, only after a SMC reset and removing all fan controls the temp was able to settle to a maximum 100/101°C.

This confirm my points and tests, again... ;)

Nice summary :). although i occasionally return to 104.
 
But on specific tasks or overall and you need to reset the SMC ?

I needed to reset the SMC once. In high performance tasks it reached 104 degrees.

I just noticed something that didn't happen before: the secondary display started jittering:

Has anyone else experienced this? I wonder if it has something to do with the Yosemite update I just performed to 10.10.2.

I performed the update but everything is good, even in the second display

Hmm. worrying.

Talked to Apple Care, they suggested to clean the connectors. My display was at the end of the chain of two external thunderbolt hard drives.

Right now it's ok, i'll keep an eye if it returns.
 
Dear lord, has anyone tried running something based on Silverlight? It's siting constantly at 104 degrees, sometimes 105. It's just a silly app to update my Harmony remote, not even graphics intensive or anything.

Blame Silverlight. Same thing happens on my mid 2012 rMBP, using the same Logitech Harmony software.

Well, it's made by Microsoft isn't it...
 
Of course, the bad guy Microsoft is responsible for the bad thermal design of the Retina iMac...

:) Of course not. Btw., I agree about the Retina iMac. That's why I didn't buy it, and keeping my late 2012 iMac for now. (Waiting for 2nd generation RiMac with Nvidia 980M or better...)
However, I've noticed myself that Silverlight seems like an bad/inefficient piece of code...

Yes, I'm waiting for the 980M too...
And Silverlight, as ***** as Flash...
 
Last fall I was practically run out of the MacRumors forums for daring to posit that there was a heat issue when running my new retina iMac with games or photoshop, and so I had returned it. It was my own fault, they said. Chicken little, I was. A troll, they claimed.

I wasn't wrong.

I returned mine for the same reason.

We still aren't sure yet, but the release of the Alienware 15 laptop with the M295X 4GB card has given me hope for a final answer. I'd love to see a Dell laptop deal with sustained temperatures of 105C!

It's not the design of the iMac we are questioning, since the 2012 and 2013 models were great, but rather the lack of design changes/improvements to accommodate for the more powerful hardware they shoved inside.

I just can't believe they would have got something so basic, so wrong. I'm still giving Apple the benefit of the doubt - especially now my money is back in my account! I trust their knowledge of thermodynamics over mine.

I don't have this experience.

Both Silverlight and Logitech running and max temps I see is CPU 42c and GPU 41c.

Blaming Silverlight is a little silly IMO since you can recreate this issue with pretty much any piece of software.

EDIT: As you can see I was doing a Google search to see how much hotter these 5k iMacs were running in fahrenheit lol.

Noticed the same thing with the Harmony software. Crazy.
 
It's definitely silverlight being an extremely inefficient piece of code, but it's also the iMac not being able to handle the inefficient code :)
