NV Silencer 5

I just purchased an nv silencer 5 for my Chaintech 6800NU. The stock fan was just a little too loud for me. I am basically how much AS5 to put on the core and mem when I install it. Two schools of thought seem to emerge from my net searching. Some say to follow the AS website, applying a very thin film with a razor blade (which I did for my CPU), and I have also seen guides online saying to place a generous amount on the middle of the core and mem chips and just apply the silencer, allowing it to spread itself evenly. Basically, I'm wondering which route to go? Any thoughts?

Thanks for your opinions

I would believe a thin amount would work best.

You must remember that the heat from the gpu and ram want to get to the heatsink as fast as possible, allowing the heat to dissapate quicker. Having a nice thin layer will allow it to do this. the thermal compound simply acts as an effecient way to get the heat dissapated.

The compound should be as thin as possible. The compound is better than air for conducting heat. But, it is much worse than direct chip to heat sink contact. So, you want the compound only to fill the air gap in between. If you put too much, there will be a layer between the two, which is not good.
In other words, if you think of the chip surface on a molecular level, it has peaks and valleys. The heatsink surface also has peaks and valleys. You only want compound to fill the valleys. But where a peak of the chip and a peak of the heatsink coincide, you do not want any compound.
So, use as small an amount as you can.

The NV5 heatsink is not made particularly well and is not exactly, flat. Most ppl are having to put quite a bit of AS5 on the heatsink so that there is contact with the DDR. A very thin layer was shown to increase the heat quite a bit because there was not a very good contact. Most of the ppl on this board who have tried it have had to put more AS5 on than expected to keep the temps down.

The GPU should have about as much as your CPU does. The ram chips need a bit more to cool properly.

Alright, thanks everyone. Still mixed ideas here, but I'm thinking that the thin layer on GPU/thick blobs on RAM sounds most logical. I'll post temp drops when it's installed!
