I want passive cooling solution

I am currently using a cheap Thermaltake Fan / Heatsink to cool my P4 3.2 GHz system. The Thermaltake cools well because the fan speed is very high. The fan is also very noisy. Does anyone know of a good passive cooling alternative, basically heatsink only that can cool a 3.2 GHz P4 under stock conditions (no overclocking)?
 
Scythe Ninja is supposed to be among (perhaps is) the best passive cooler in lower/quiet airflow systems. With more airflow, I guess the Scythe Infinity would be better, but then you're using a louder and faster fan.
 
The ninja looks good. But it looks like it requires a 120 mm fan. Is there a heatsink that I can use for P4 that is completely passive -- no energy, no moving parts?
 
I'm using my ninja in my p150 case. I took out the stock antec tricool case fan and replaced it with the really quiet scythe fan that came with the ninja. There's no fan on the ninja itself, and with the scythe fan running as slow as it can, my e6300 at stock speeds is at 40 idle, maybe 60 load (never really loaded, I don't really do cpu intensive tasks). I'm guessing your p4 will run hotter so I advise you to increase the case fan's speed or something.

the ninja can be used with out without a 120mm fan depedning on the application.
it will probably work ok as a passive cooler in ur case...
 
I forgot to mention that I do run Folding@Home under 100% CPU load during the day. I think I am going to swap the CPU with an E6700 from my other computer, install the largest heatsink that I can find, leave the case open-air and see what happens... I am not sure if passive cooling can cool at Prescott under full load...I suspect not. The heat will be transferred into the heatsink efficiently, but from there, I think it will diffuse into the air too slowly.

Unless you plan on using no fans at all, I suggest you just don't put it in a case at all and or install it into a 1U enclosure with the top off and then you can leave it flat somewhere. Then you'll get true radiant heat but with a case, its enclosed and won't get natural air circulation moving through the fins.
