My friend is building a socket 939 system of which will be transported a lot. He lives in toronto, which is a big lanning city :). He also wants it to be very silent and that is why he is using seagate drives and silenX fans. When he asked what heatsink he should get, I immediately said the zalman 7700 because of its performance and low noise. Then, I remembered that his computer would be transported a lot and the zalman 7700cu is almost 1kg (918g). How much performance loss do you think would be seen from going to the zalman 7700alcu which is only 600g?

The other option would to use thermalrights new line of alluminum coolers which are only 360g and 370g for the xp-90 and xp-120 respectfully. Which do you think would be better? Xp-90 w/ 36cfm 14dba silenX fan, or a xp-120 with a 120mm 58cfm 14dba silenX fan. I would think the xp-120, but I have also seen a lot of people report that they acheive better temperatures with a 92mm fan as opposed to a 120mm fan because of the larger dead spot on larger fans. Yes I know 36/58 cfm is very little for a 92/120 mm fan, but this computer needs to be inaudible; from past experience, I have found 20dba fans to be extremely noisy in circumstances where airflow was blocked (ie heatsink / fan grills). Another idea I had to reduce noise, to eliminate the need for a high static pressure fan, and to eliminate a dead spot was to make a stand for a fan using a gutted 120mm fan or a 120-92mm adapter. 1. Which idea would be best? An adapter or a stand? 2. Will this even work :).

So in summary if you decided not to read the whole thing (I don't blame you), I need a high performing light hsf that is inaudible and fits the new dfi Nf4 series.

I'd suggest XP120 with a 92mm fan.

Use a 120MM fan, it will make less noise and push more air.

w/ or w/o 120mm-92mm adapter?
wouldnt it make less noise with the adapter since there will be less resisitance?

I think that an adapter will only increase the noise level, it is putting more air though a space the same size. Also it increases turbulence because the air needs to change directions in order to go from 120MM to 92MM.

If you're going to use the 120mm, get one with a small dead spot, otherwise a 92 might be better.
