The Noctua NH-P1 -- any performance comparison reviews or firsthand experience?

I've been away -- not doing any computer building, spending my time in the "Social" forums. But I've come back to HW and Technology as I'm building a machine with 4-year-old parts. Even so, I contemplate building another system next year -- probably on an Arrow Lake platform. I happened to come upon this heatpipe cooler by Noctua: The Noctua NH-P1 It also allows for use of a fan -- it doesn't have to be fanless. But I want to see some performance comparisons, or hear from someone who is using one. I'll keep looking myself, but I thought I would post this quickly. Gamer's Nexus has a comparison review which shows most other coolers outperforming this, so "false alarm". Nothing to get worked up about.
