When I said seated correctly i was referring to proper contact. Meaning that the copper base was making complete, flush contact with the gpu and memory.Also known as seating the heatink correctly on the gpu and memory. It was very clear that "proper contact" was being made because upon removal of the heatsink, many times, complete coverage of all surfaces (memory and gpu) with the correct amount of theramal compound. I should also add that the first unit actually broke. One of the mounting lugs snaped in two due to tighting, and losening, the heatsink so many times.As I said it was replaced by the great guys at crazy pc, and I had the same issues and results with the replacement unit as well. That was not confusing to me and I am sorry that it confused JBDAN or anyone else. I do not feel that the nv silencer is worth your time or money if using it on an ultra.I think I have made completly clear.
I guess we agree to disagree at this point. thanks for your input on this topic. Since you put up a link to this site here are the results on the 6800 ultra from that review:
6800 Ultra
I chose the 6800 Ultra first because this card may be the most power hungry, heat producing video card on the market. As you can see, the stock heatsink for the 6800 Ultra is exceptional already. The heatsink itself is comprised of a large aluminum heatsink, while the ram is heatpipe cooled with aluminum rods and another large aluminum heatsink. The fan is a LOUD delta blower that pushes a lot of air. Overall, the stock heatsink is very impressive. One flaw I need to point out, already discussed previously, is that the new Silencer will not work on a double bracket video card, such as this 6800 Ultra. The exhaust would be blocked for the duct if you were to use the existing double PCI bracket on the video card. My solution was just to exchange the bracket on the GT for the Ultra and then dremel the VGA connector to accommodate the DVI connector. Here are the results
Idle stock 50 silencer 49
load stock 72 silencer 69
Notice how the Silencer doesn't do much in lowering temps. The reason could be Nvidia's need to integrate an already sufficient cooling system for their power hungry 6800 Ultra. The Silencer did manage to reduce overall ambient temps, but not by much. One thing to note is the decrease in overall sound from the VGA fan with the Silencer. The 6800 Ultra comes equipped with a thick Delta blower that can be hard on the ears once the thermal fan control function starts kicking in. The Silencer was noticeably much quieter. The max overclock for both coolers were the same, possibly indicating I have reached the limit with air cooling since this card was flashed to a 6800 extreme edition.
