So, I made the decision to install a Mars 760 into my rig, which first impressions are now kind of making me regret as it has the horrible problem of running at ridiculously high temperatures i.e. 105°C. The official statement from Asus is that this can run at 105°C for 10,000 hours with no adverse affects, but I never quite believe the 'official' spin.
I tend to game for long periods at a time, so you know 105°C heat is making me nervous. Cooling and airflow in my PC are optimised, however as I've mounted the card in my first PCI slot, I'm considering potential overheat to the peripherals mounted below (sound card, PCI SSD and PSU) so perhaps a re-think of the setup may be needed. I guess my question is whether I'm just being paranoid and whilst this kind of heat would be bad for other cards, this one should be fine and you know, believe the ROG, or should I be worried and consider other solutions here?

This is not how this, or any, graphics card should work. You should never exceed 90 degrees under gaming, let alone 105 (shut-off temperature). It is even a good thing to keep it under 80 at all times for longevity sake.
Have you checked the fans on this card? Any dust on it? Are the fans in the card even spinning? Do you have any fans in your computer case, are they spinning too? Did you try with side panel of your case removed?
Many questions, I know....

It's fresh out of the box, not even 24 hours yet. The GPU fans are the ROG version of Asus Directcu II so supposedly an improvement on what's already considered one of the best and the case fans are in push/pull configuration. I've not tried running it with the side panel off yet, so I can give a try, but based on what's happened already, at best I predict maybe 5°C drop in heat.

Well, sh*t. It seems to have worked. Taking the side panel off whilst running Ass. Creed IV at maximum settings, seems to have worked. Currently, it bounces between 53°C and 67°C under load. It's pretty early on in the game, so I'll check back when the character's in a city with a lot of NPC's in case this has a different result.

Glad it helped, mate. Now, try with side panel on... Then off... And if it goes on from bad to good to bad to good you know that either the case should be replaced or more fans / better airflow created. Possibly you need more space inside the case, maybe the airflow is obstructed somehow with cables or other components. You might need to rearrange the cabling or components inside the case. Almost forgot (lol): which case are you using?
As for the temps, yeah, they are wrong (idle too low) but the sensors are sometimes not precise, I wouldnt bother with that.
