Have a Scythe Big Shuriken low profile heatsink for sale. Was only used for a week or so and is in like-new condition. SPCR did a low profile heatsink roundup that has some info on the Big Shuriken's noise and performance. Here's a link to the article.

Looking for $22 shipped (SOLD) within the US. Heatware is under frostedflakes.

Just curious, why are you selling it?

Built a low profile system, but ended up going back to my old tower for a couple reasons. The cooling wasn't that good, it was loud, and it wasn't that much more compact than my NSK3300 (actually it seemed a lot bigger, despite having a smaller volume, because it was a few inches longer and deeper). I was very pleased with the Big Shuriken, though, it seemed to cool the processor quietly. But now that everything is installed in my old case and I have enough room for a Ninja, I'm using that again.
