The problem is not there due to bad cooling. Definitely...First, because a lot of people are seeing it and experiencing it and they cant all have bad cooling at the same time.
Oh yes they can. Unless they have MSI Afterburner's statistics screen up all the time to display temperatures (and check it after each game, or use a screen overlay or Logitech G13's LCD display to show temperatures constantly), how can people know what temperatures their system reaches normally? In such a case, it's only when they hit a problem that these things will be checked.
After i saw OS getting it to 110 C, i took it out, cleaned it and the whole case thoroughly, took off the GPU cooling and applied new coating of thermal paste. I even added one more case ventilator to blow out hot air and enabled the front one to bring more extra relatively cooler air inside...That did not help at all. For OS.
Sorry to hear things didn't work out, but air cooling can be a tricky thing to get right. I found I had to have two sets of fans in push-pull configuration with my GPUs (2xNvidia 460GTX originally, now 2x580GTX), one inside the case pressed up against the GPUs blowing towards the rear, and a second set outside the case blowing the same way (effectively sucking hot air out).
During my experiments I found that having a fan on the side of the case over the GPUs (sucking cool air in) was quite effective but I wanted to keep the case sides clear - however that may be worth considering for anyone wanting to improve GPU ventilation without going the water-cooling route.
I run Heaven and my stock 760 is under max load and gets to 75 Celsius. This is designed to take your HW to the limit.
Unigine Heaven is pretty demanding, but not the most punishing benchmark out there. 3DMark2006's batch triangle test (those using higher numbers of triangles) can result in higher power usage (and slightly higher temps) but you need the Pro version to run that part multiple times for stress testing.
However the most demanding game I have come across is
Hard Reset (a well-executed first-person shooter with great graphics but a dodgy plot). That can push my GPUs to 80 deg C while Unigine Heaven, 3DMark, etc only manage 75 deg C (and D:OS gets to 70 deg C). Sadly, while it has a demanding benchmark, it can't be looped automatically so you have to keep re-running it to stress test. Anyone complaining about D:OS overheating their cards might want to give it a try.
To anyone complaining about D:OS not being "optimized" - get over it. It's just been released and
no game is fully optimised or bug-free on release. If a smooth experience is your priority, wait a month or two for Larian to fix all the reported issues.
