Me again!

here's a question...
So my Nvidia panel didn't show where I could adjust fan speed, so I searched it, found this:
http://www.fanhow.com/knowhow:Change...speed_27843686
which directed me to Nvidia site where to DL the performance part of the control panel
http://www.nvidia.com/object/nvidia_...ools_6.05.html
And so I installed it,and it also has a nifty little system monitor of it's own, which I like,although it fills the screen and I'd like to be able to minimize/make it a little box....
Moving on.... but when I go to look into the performance section, it gives this
dire warning that you must accept before being able to use the performance section, called Accept End User Agreement which I can't even c&p but basically says the software utility may cause system damage and void warranties, and so on etc....all scarey bad things!
I guess this is warning ppl who plan to go in to overclock, etc.? Idk, you guys know anything about this utility? I really just want to be able to manually increase my GPU fan speed, but now it has me scared ....maybe I'll wait til after this weekend to see how necessary that will be anyway....
Thoughts?
