The easiest way is to probably open up your NVIDIA control panel, click on 'Adjust GPU Settings' under the performance tab, and you can use the 'Custom Clock Frequencies' and from there you can turn down both your Core & Memory bus. Hope that helps.

I was told that once you get into the 70's it's not so good, not blowing up hot but still pretty hot, and when I do feel the card it is Very hot.

If I were to lower it in the Adjust GPU Settings, what Should I set it at to maybe not have it in the 70's while in game playing.

just try turning up the fan speed instead of underclocking it

lol, my card runs in the low 90's and it seems that most nvidia cards are around your temps, but can handle into the 80's, so unless you are having problems I wouldnt worry about it.

Best,

Okay good, i've set the GPU fan to 80% and it runs about 65-67 in-game now which is good.

Is setting the fan higher gonna make it much louder or like blow it up or something lol What would happen if I set it to 100%?
