ok, another thing.
look at this picture. (GTX460 Fan Pin)

The Fan power pin is no correctly attached to the power, "why?" its because when i push it harder , or when I fit it exactly to the end, the fan speed becomes slower, and its just like a 5v case fan air.
and as you can see the picture, I did that because the fan speed becomes super fast, like 100% speed.
with that, I can change the fan speed (MSI afterburner, EVGA Precision ,Thunder Master ....etc) but I don't see any difference when changing it, but when the fan power is pushed harder on the socket, I cant change the fan speed or the scroll to increase , and ended up with Mouse lag.
any ideas why is this happening? and is this safe???
