Zalman CNPS 10X Extreme or Xigmatek Dark Knight S1283V?

I currently have a Zalman CNPS 8700 NT, but am returning that due to just buying a random compatible HSF and not conducting research.

Right now, I'm opting for a new CPU HSF and after reading several reviews, I've decided to get either the Zalman CNPS 10X Extreme or the Xigmatek Dark Knight - S1283V.

Performance-wise they seem to be on par with each other. However, I lean towards the Zalman because my whole system is built around a blue LED/black theme and it has the PWN mate controller. The only thing stopping me is that the Xigmatek is 45 dollars and is a lot quieter, whereas the Zalman is 70 dollars and a lot more noisier. I'm wondering if the extra 25 dollars is worth it?

My build is:

Case: Antec 902 (I've changed it so that the bottom front intake fan is placed on the top of the middle fan, so it blows air directly to my RAM/CPU HSF)
Mobo: MSI 790FX-GD70
CPU: AMD Phenom II x4 955 BE (I want to OC around the 3.8ghz range)
RAM: Mushkin DDR3 RAM (996657) - This is just to clarify that I have a low-profile RAM and I'm using the outer slots on my MB.

Also, are there any better alternatives? Like the Scythe Mugen 2 or Sunbeam's Core-Contact Freezer? I would prefer it to have a blue LED with a black/nickel-plated finish to it, but other HSFs are acceptable as well. Thanks.
