I'm not sure but I know I read at least one person saying their fan was quite loud doing normal tasks, they returned it and the new system was quiet.
Got a tip for us?

If you mean where are my game choices, specs and temps, it's here...

If you are asking about dodgy thermal pastes... there was a more than a couple of people... two here in the following thread. One - SchneiderMan - who had his problem resolved after getting a replacement. I only started thinking about heat after reading that post.
His 1st complaint about excessive fan;

Subsequent update that all is ok;

my takeaway from the thread;
1) I found that GPU is generally hotter when running Chrome instead of Safari.
2) iStat and GPU-Z for me is reporting startup temp ~15c higher than ambient temp even after immediately waking from deep sleep... I feel somethings wrong there... either with the programs or with how Windows and OS X reports it
3) On normal tasks, I found OS X to be cooler than Win7 under bootcamp.
4) When playing games, Win 7 was cooler, allowed higher settings and gave better fps.
Finished single player campaign of COD: Advanced Warfare at 1440 and everything on max with no AA, it was buttery smooth throughout and never got sluggish. Maybe your issue is with the game? I played under bootcamp windows 8.1, from external USB3 SSD.
These are great observations, very useful to note. I've noticed that Chrome hits the GPU and the CPU harder doing the same thing. Really makes a difference on a MBP.
BTW there's nothing wrong with the temperature sensors here. The GPU is small piece of silicon, easily capable of heating up 15C in a fraction of a second as soon as it's on and dissipating tens of watts.
Does that mean it's normal for all gpu to be around 15C higher than room temperature when you start your iMac? I think my m295x is also usually 15C higher than room temperature, if not slightly more.
Nothing magical about 15C exactly, but yes, of course it would generally be higher. How much higher is just an artifact of the rate of cooling that the heatsink/fan is applying.
you wish. light activity after sleep mode like writing this post brings the m295x to 56C with 25C ambient room temperature, which is ok since fan at 1200 rpm is hardly noticeable unless it's very quiet.
even though I was lucky and don't have the mission control issues or the youtube issues with the m295x, the gaming issue with gpu diode temp and consequent fan speed remains. delivery will pick up my imac next week to have it returned. will probably use my macbook air until either design flaw is fixed or a smarter gpu choice is offered.
Ok my temperatures wouldn't rise that quick. I would have to constantly surf and watch videos for a couple of hours to get the gpu close to 60C. Usually hovers in the 40's if I'm just surfing...
I have been working on benchmarks for around 50 games and apps over the past week; a continuation of some of the work I did when the 2012 680mx iMacs were released two years ago.

But heat and the throttling I have experienced is a big problem for anyone wanting complete performance. As it stands, is the screen worth a GPU that is only 3-5fps better than a stock 680MX, and worse than an overclocked 680MX? My heart is breaking, I would have paid anything for a 980mxThoughts?
I am wondering if people have experience yet with the faster CPU - i7 (4.0 GHz 4790K) along with the standard GPU - 290X? Does the GPU generally run cooler/unthrottled in this combination? I like the 5K and the faster CPU. I'm not a gamer and I'm not sure if the GPU would matter for ordinary digital imagery use.

I know system memory would, but I'm not so sure a larger video buffer would help OpenCL/Compute...
How did you get your Bootcamp partition onto an external drive? I just had a bit of a nightmare as per this thread https://forums.macrumors.com/threads/1818859/
Not sure if this was posted or not. Barefeats.com posted benchmarks comparing the 290 to the 295, and surprisingly - the 290 beats the 295 on a couple of them. Makes no sense right? They guessed it is due to faster clock speed in the 290, but I think it may have something to do with the issue we're noticing here.

First link: 1/4 tests in which RiMac base model is better than RiMac top config = 3/4 tests won by RiMac top config!
Second link: 1/10 tests (one game benchmark to be precise) in which RiMac base model is better than RiMac top config and 2/10 tests in which iMac 2013 top config is better than RiMac top config is better = 7/10 tests won by RiMac top config!!!
In total: he 290X is better in only 2/14 tests and when you want to consider two to be a couple, fine... however I think it is pretty obvious that the 295X is better than the 290X, the difference might not be significant (5-10 FPS) but there is definitely a difference.
The problem with barefeats' benchmarks is the role of the CPU. I think we need to wait for a comparison between i5, 290X and i5, 295X (or i7 in both cases).
i now found out why my win8.1 bootcamp wow fps was so slow: energy settings.
putting them to high and you'll get 80-120 fps with 4k resolution and medium settings in wow and full fan speed/noise.
putting them to energy saver you'll get annoying 40-60 fps with 4k resolution and low settings, however it kinda lags and gives me headaches but fan speed/noise is more moderate and rather tolerable.
edit: i7 and m295x. if you can stand the noise, this is quite the game experience!

i did but through my open headphones i still heard the fan noise which was about 40db.

I recommend Beyerdynamics DT770 Pro (80ohm). These headphones are great, and also reduces noise about 20dB. You don't notice any fan noise with these on.
Beyerdynamics T51p are also great.
Enjoy your RiMac!
Summer days = hot
Received my i7 4 retina iMac the noise of the fans and comments about high temperatures are making me worry about hot days in summer. These days in November outside temps are about 10C, I am worried what iMac will do, when outside will be very hot and not necessary AC in the room.
Anyone out there using RiMac in tropical conditions? Will the fan go on even while surfing or doing regular stuff? What do you think? I am seriously considering sending this one back and wait for the revision. These 100C processor temps look no good at all.

Wow, when I am playing games, I only wear 1 earbud (cheap adidas earbuds I originally bought for the gym) and I can't hear the fan noise. If I take the one earbud out, I can but it is pretty faint. I like to be able to hear other things in the house (what my cats, dogs are up to) which is why I only use 1 earbud but it is enough to drown out the fan noise when playing games. I don't hear the fan noise during other times.

I installed win 7 now and played all morning Assetto Corsa in 2560x1440 with everything on high and only disabled AA.
In a Race with 10 opponents I still had always over 60Fps and temp of gpu goes over 100 degrees.
I don't notice any throttling.
Edit: I use the Program Mac Fan Control to trigger the FAN earlier.
Edit2: i7, m295x and 24GB RAM
