Why my GPU fan gets loud while playing games and it gets hot as well while the temperature of my GPU while playing game is 65-67 and without playing games it stays to 40?
My Specs: core 2 duo 3.0 ghz.. nvidia geforce gt 630 2 gb, 160 gb hard disk, windows 7 32 bit.. intel DG33bu mother board.
Yea, when a fan spins, it creates noise, and when it gets told to spin faster, it creates more noise - You might want to check if your gpu fan is all clean, but other than that its pretty damn normal (also whats the excact name of your graphics card?)
As the user above says, when things get hotter from use, the fans tend to be told to go faster(more voltage or a pwm signal says faster).
This is perfectly normal with modern hardware. Older hardware used to run the fan at one speed all the time, but that would be too loud with todays more powerful hardware(this modern hardware clocks down when not in use so it runs cool and only needs a slow fan speed until it gets working).
You mean to say that it will not damage my card or something? I just bought it.. what if i play for 3-4 hours.. will it damage.. I'm afraid because i just bought it.. i don't want it to be dead right now!
No problems with those temperatures, they are actually very good for a card under load, and it will be safe up to 80C or even higher.
That 40C when idle is normal, it is just because the fan is running very slowly, to keep the card quiet.
