Subnautica causing GPU to overheat!? O.o

This problem is becoming annoying I must say. The graphics desperately need optimization. Even on low graphics it still causes my pc to shutdown after about a half an hour... this is the only game I've ever encountered to do this to my rig. I keep my pc dust free, and even in an AC environment it just seems to push my GTX650 too hard.

    Yes, I have noticed that the fan in my labtop goes into overtime whenever I play this game. Hopefully as time goes on so the devs will be able to optimise the graphics a lot better to prevent this. Perhaps this is why I get the regular lags as I play.

    While the game can surely benefit from optimizing, no pc should ever overheat in any situation.
    If the driver allows the card to overheat, the cooling in the pc is to poor to begin with.

    My pc works fine with any other game. GTA V dang near maxed out no issues. Subnautica here for the past month or so is a different story. Even got the add-on for nvidia control panel to make my gpu fan run at 100%. The most I can push out of SubN is about 30 minutes and that's on low graphics. So I just don't know.

    Got speedfan to check things out. My gpu stays around 35c give or take. When I play Subnautica within 15 minutes it's up to 80c O.o :( I clean my pc religiously, so I don't know what else to do. Do they sell water cooled gpu's yet?

    I suppose a better gpu is in order, but I was trying to wait until I can get a newer one and the Oculus at the same time... perhaps a new gpu is my only option.

    80 degrees C is high, but not THAT high.

    My GPU (Radeon HD 7870) is around 65-70 degrees C after hours of playing. That is with a load of 90+% on it while playing.

    Maybe the heat from the GPU is causing something else to overheat?

    It may be the duration of usage.

    Most GPU and CPU are going up and down in frequency to preserve both power and lower heat. (Ironical many max performance profiles force the existence of a problem I shall explain.


    Most know cooling basics.. Heat is produced by gpu, cpu etc, cooling transfers this to air, fans push air out. The more and faster this is, the cooler your gpu.

    But the cooling elements THEMSELVES also heat up. Ideally they have chance to cool because the gpu throttles down when it can. Also as air/fans transfer heat away from the cooling element, they can in theory become cooler again.
    Now a problem of saturation arrives where the gpu is pushing out so much heat on such a continues basis, that the cooling element does not cool down. From this point on cooling will take a hit.
    You see, if the cooling element is not cooling down, the gpu can not transfer heat to it. As in, if both are roughly the same temp then the cooling element can not absorb more heat. It has to get rid of heat FIRST.

    This problem shows up faster when GPU/CPU are working near max efficiency nonstop. The only real solution would be a cooling element which can sustain this heat punishment and still cool down enough, with correct airflow.
