What is the best bet for fanless cpu cooling on my 775 board? My CPU only pulls 20 watts. If anyone could link me a heatsink or any other option, plz do.

A Thermalright HR-02 would be my first pick Its big tho, so i would only get it if your case has a 120mm rear exhaust.

These guys can most likely be run passive @ 20W, and if you have a exhaust or any air movement in the rear even better.
They have a wide fin spacing which was designed for that.

Another is the Nofan but its very pricey.

Are you going for a complete passive build?
Even adding a low spin fan in the rear exhaust will help immensely, and not generate a lot noise.

Thx for the recommendations. A little out of my price range tho. I was hoping for something cheaper. What low spin fan would you recommend for the rear exhaust?

The thing about passive is they require mass.
Mass = $$$

As for fan selection, these guys are great, IMO the best value for performance / noise:

These guys are the gold standard for noise / performance.

The grey noctua is basically the bulk version of the brown/tan, in a cheaper retail box with less accessories, hence the difference in price.
