LGA1366 Passive cooling?

I've never had a passive heatsink on a CPU ever, so I'm not too sure how it compares. I'm planning on getting a i7 920, probably not going to overclock it. I want minimum noise in this thing, and my case is an Antec P180. Right now it has stock fans, but I want to swap the back one for a Noctua NF-R8, once again because I heard they're quiet but still give decent airflow.

Any reccomendations/thoughts(Is this even going to be enough)?
 
I doubt you'd want to use the Ultra 120 Extremes with out a fan. With a fan you're looking at 60-80C. So without one is extremely improbable.
 
Use a low-speed fan (or 2) on a TRUE - it will be quiet & cool enough. Better yet, watercool it!
 
The problem with passive, is how much even a little bit of air flow helps. A decent 120mm fan, such as the Noctua NF-P12, running at 600rpm will be dead silent, and provide good results.
 
Dude, I have a P182. And with all the fans on low....and even with the stock i7 cooler, it should be pretty damn quiet. I wouldnt recommend passive cooling even if your not overclocking. Stick with the stock and maybe you could set the RPM on the fan if it bugs you with speedfan.
 
I'm using the low voltage adapter with the kit, and runs cool to the touch, even load. Once I stopped the fan with my finger, the heatsink then begins to get warm, and then very warm, at 20% load. I would avoid running passive, even with a good cooler. :eek:
 
passive cpu cooling is possible on a platform like atom that won't require significant case cooling. if you're intending to passively cool an i7; overclocked or not, you will still require near perfect case cooling.
 
I would recommend a fan at 7 volts. Something that already is around 25db. I can promise you if you have stock cooling on your video card, that will be much louder then the fan
 
Do NOT run passively with that CPU. Most CPU heatsinks have fins that are too tight for passive operation anyway. As others have said, even a slight amount of airflow will be FAR better than passive.

My TRUE with an 800rpm Scythe fan was dead silent.
 
ManiacChart,

I have a Noctua NH-U12P 1366 in my TJ09 and I'm using the ultra-low noise adapters. So far, my 920 (still) idles lower than the stock Intel heatsink. I couldn't believe how loud the Intel heatsink was. It would easily eclipse my GTX 260. Now I can actually hear my 3 hard drives again.
 
even with the stock fans for the TRUE you shouldnt be able to hear it in an p180 case unless its sitting right next to your ear..
 
Alright, thanks for the input everyone! Lots of great answers!

Looks like passive is out the window then. I'll look into the low RPM solutions.
