I have an 8 core cpu and decent vid card. I get cpu temps hitting 80*C on 1 or 2 cores and the alarm goes off. Running bench monitor in the back ground for info. Any other games I play on this system give normal temps. Only this game cooks the cpu's that hot. What's up? Vid card ( R9-380) hits 80*C sometimes. I run open case boxes always.
Looks like NMS runs at least a couple of tasks in the background that intensify when the normal runs are less frequent. So in low intensity situations you would basically see a little bit lower graphics card "shader"-drain depending on how complex the scene is. And an increase in bus-traffic and background tasks on the cpu.

So typically the cpu will have something to do pretty much all the time.

Normally, games won't do that - instead you have small bursts of cpu activity once in a while, and then nothing in between. This is why the comical overclocks on certain rigs nowadays actually "work" in practice fairly often. Because what increases the performance is higher burst performance. So if you can sustain that burst for the typical 3 second peak loads you need, then the overclock, practically speaking, really does increase performance.

Because the processor really does perform better up until the point when it hits the max watt-drain and is throttled, or hits max temperature and is throttled. In the same way, a badly cooled processor can also perform perfectly fine with a cold coffee-cup put on top of it.

Basically, if you have an fx hexacore of some sort, and you hit 80 degrees, this is way too high. This should never happen outside some sort of crackling super-clock and while running a linear benchmark that fills all registers continuously or something.

Anyway, so what you want with NMS is basically stable max load. First thing I would do on your rig would be looking at the goop on the cpu, really, because of how the cores have different temps. That's not.. really supposed to happen normally. After that... invest in a good cooler, and plug your cabinet shut, and install a 120mm fan, get a decent draft, etc.

i have a 4 core i5 and my temps are all normal (max around 60-70 degrees C), so i've not noticed anything like this. Are you running other stuff in the background while you play perhaps? But it is odd you only get this with NMS and not other games, as that would then indicate a hardware/cooling issue, but you have a specific NMS issue. Very strange.

Mobo kicks the voltage up with load and cooks the cpu. i did disable the OC options but it doesn't listen. Running a 8350 cpu is too much for this mobo. Will put a 6350 cpu back in. its not as hot running and Its in my other game rig. i have 2 game boxes. same mobo and vid cards (different brands) with 6350 in one 8350 in the other. the 6 core runs around 65*C with vid card hitting 83*C on occasion. The 8350 ran the vid card at 65*C but cooked the cpu with 2 cores hitting 83,85*C.
Perhaps the ambient temp must be very hot where you are? Maybe invest in better cooling/ventilation before you damage your rig! High temps make me worried ;) Good luck with fixing your issue :)

Its mobo specific. Place the 8 core in a different mobo and runs fine at 65*C. No muss no fuss. Won't buy the troublesome mobo again.
