Until the machine crashes... Honestly, if the machine runs FurMark longer than UT crash time limit, it's probably not a problem of an over heated GPU.papercoffee wrote:How long should FurMark run?
I neither have concrete data - only the manufacturer can give reliable specifications (maybe have a look at manufacturer's web site). But 100°C seems a lot; I would put a fan on it (it is a passive cooled graphic card).papercoffee wrote:I reached 100°C after 3 minutes. I have no clue how hot a video card can get before it's unhealthy.
If you decide for a GPU fan, consider also mounting a case fan - twirling hot air in the case instead of blowing it out means other components will get warmer also.
In the years of handling hardware my guideline has been: if you cannot touch it anymore, it's too hot. Furthermore: the higher the temperature, the shorter is the life time of electronic components.
