I regularly sit in my room at (30.c) 86.f before I even bother turning an AC on, most people are in big enough rooms where a GPU even at full load will barely even change the ambient temperature, unless you're in a prison sell then it won't really make a difference, also don't go spreading misinformation, a GPU idling at 40.c when its fans are off (Which its designed to do) will not kill it, most GPUs run anywhere from 55.c (131.f) to 75.c (167.f) when under load and air cooled.
To be clear again, when the GPU is in its auto fan off mode, which 3000 series NVidia cards ship with by default, they will go all the way up to 45..c (113.f) before the fans kick on, this is normal behavior, don't listen to this guy...
I would also like to add that I have built over 15+ PC that all included NVidia 3000 series GPUs all configured from the factory to turn off their fans if below 45.c (113.f) and not a single person has come in crying that its going to kill their card
I'm done with conversation, no point in arguing with you uneducated users anymore...
