The NV Silencer is an incredibly good cooling solution. I recently got an eVGA GeForce 6800 and the stock fan on that has this obnoxious whining sound, not to mention the fact that it doesn't exactly cool all that fantastically. After using the stock for about ten minutes, I immediately went and put on the NV Silencer 5 Rev 2 that I had bought with it. I used the stock thermal pads for the RAM and used Arctic Silver 5 for the GPU. When I first installed the card, I didn't notice much of a difference in the cooling. I later came to find out that a cable from inside my system was blocking the fan which prevented it from spinning at full speed. Hence why my video card ambient temperature was around 50 C and under a full load it went into the mid 70's. With the fan fully able to turn now, the idle temperature of my GPU is only about 43C and under a full load it gets to around 61C. The biggest benefit of all is that my overall system temps have dropped about five degrees C thanks to the cooler pulling air from inside the case, and the fan itself is nearly silent. I can't hear it over the power supply/CPU/case fans that I have. I'd say that it's well worth the money. 😀
